To properly assess a specific risk, you need to have some idea of how likely it is to happen. For example, the likelihood or chance of being in a minor ―fe nder bender‖ is much greater than the chance of being in a fatal collision. Teenage behaviors contribute to teen-related crashes. Things that aggravate the problem are Inexperience and immaturity combined with: Speed Drinking and driving Non seat belt usage Distracted driving (cell phone use, loud music, other teen passengers, etc.) Drowsy driving Nighttime driving Other drug usage “...of injury, damage, or loss.” — These are the consequences of a crash. They are an unwanted outcome of an activity that anyone would want to avoid. ―Injury‖ could involve yourself or others, and could be permanent or even lifethreatening. “Damage” involves personal property. ―Loss‖ could include things such as financial loss, loss of opportunity, loss of convenience, loss of time, other losses. Assessing risk involves knowing what the consequences could be. For example, the consequences of a high-speed, head-on collision, or any collision with a train are far more serious than a minor fender bender. The driving task involves more than just the skill to operate a motor vehicle. One of the most important aspects of driving is handling risk. Young people as a group have been found to be more likely to take risks. This is one possible explanation for the fact that young drivers are over-represented in motor vehicle crashes and fatalities. Even though they are more likely than older drivers to be risk-takers, they do not necessarily have the ability to either properly assess the risks in driving or to handle potentially dangerous situations which they may encounter. Driving is a risk-taking activity. Each driver accepts a certain level of risk just by getting into a vehicle. Risk acceptance is a natural part of driving. Drivers who take unnecessary chances demonstrate risk-taking behavior and the probability of being involved in a collision increases by the elements of risk involved. Therefore understanding that ―r isky‖ activities are based on how we assess the risk and how much risk we are willing to accept is the first step to becoming a safe driver. Many times, driving behavior is based on risk perception rather than actual risk. 5—5 Risk Factors Types of Collisions Participation in the HTS involves constant risk that must be predicted, analyzed, and minimized including the effect a driver’s actions have on vulnerable roadway users. Benefits of predicting, analyzing, and minimizing both potential and immediate risk factors. Risk and the Driving Task. The driving task involves more than just skill to operate a motor vehicle, it is just as important to make reducedrisk decisions. As hard as you try, you may not always do things correctly - many incidents could have been avoided or eliminated if you could. The problem is, there will always be factors working against you, but there are many factors working for you as well. Risk Assessment — Involves Knowledge. While it is impossible to determine with accuracy the levels of risk in all driving situations, there are guidelines to help you assess risk more accurately. Consider the possibly of a dangerous situation developing. Prepare yourself to take action in the event of a conflict. Always consider your options and the consequences of your actions. Head-On Collisions. The possibility of serious injury and death is more likely with a front-impact crash. Head-on collisions are more likely to occur on two-lane highways, in narrow lanes, and in construction zones. Rear-End Collisions. Rear-end collisions are one of the most common types of multiple vehicle collisions. Tailgaters are especially at risk. You can lower your risk if someone is tailgating you by slowing down to encourage the tailgater to pass you. Side-Impact Collisions. Despite recent safety advances in side protection such as reinforced steel beams in doors and sidemounted airbags, most vehicles are less well-equipped to withstand a side impact than they are a head-on impact. If you are at risk of colliding with the side of another vehicle, honk your horn and flash your lights to warn the other driver. Swerve right rather than left when there is no time to look first. If your car is about to be hit, your best option is to accelerate rather than brake if the way is clear. Accelerating will get you past the danger more quickly. Braking may actually contribute to a side-impact collision, especially if the other driver has judged that your speed is sufficient to avoid a crash. If the way ahead is not clear, another alternative is to turn in the direction that the other vehicle is moving to force the impact behind you to the rear of your vehicle. If you turn in the direction of the approaching car, you risk colliding head-on with it.

To accomplish this, a driver must process information from the traffic scene. Information processing is the brain’s ability to interpret information provided by the human senses and to employ critical–thinking, decision-making, and problem-solving skills in performing legal and responsible reduced-risk driving practices in the Highway Transportation System. Place your hands at 9 and 3 or below on the steering wheel with thumbs along the rim. Adjust speed for conditions. Drive only when alert and able to efficiently process information from the driving environment. Adhere to traffic laws - they are designed to improve safety and efficiency. Vision is the main sense that provides the information to the brain so the brain can employ critical–thinking, decision-making, and problemsolving skills in performing legal and responsible reduced-risk driving practices in the Highway Transportation System. Immediate Risk is the high priority possibility of having a conflict that results in a crash or collision needing a driver visual attention. Potential Risk is the probable possibility of having a conflict that results in a crash or collision. Ways to Predict and Analyze Driving Risk Examine in detail what threats or changes in conditions could increase/decrease threat Examine in detail how the potential or immediate hazard might affect your intended path of travel Drivers need to develop reduced risk driving habits. A driver must make every effort to reduce risk in order to lessen the possibility of a conflict. Ways to Minimize Driving Risk. Reduce the possibility of conflict by putting more space between your vehicle and the hazard. Wear your seat belt and sit at least 10 inches from the airbag. Turn your headlights on at all times. Continue to improve your traffic safety knowledge and refine your driving skills. Keep a margin of space between you and other vehicles. Wise drivers keep vigilant control over the space in front of their vehicles. Use a simple visual search process—SEE iT (Search, Evaluate, Execute, in Time) Maintain your car and understand how it works. Develop safe driving habits. Position your vehicle to maximize your ability to see and be seen by others. —Failure to Wear a Safety Belt — Even though failure to wear a safety belt is seldom the immediate cause of a crash, it often makes the consequences of the crash worse. Studies have indicated that failure to wear safety belts is often associated with higher risk drivers. For example, in one study, researchers at General Motors Research Laboratories found that drivers who tended to leave shorter following distances were also the ones who most often failed to wear a safety belt. 5—7 Factors that Contribute to Risk The driver — Very often the drivers actually create the high risk situations they become involved in. A lack of risk awareness is one possible explanation for why this happens. According to the Texas Department of Public Safety statistics, the following are the seven driving behaviors that Photo Courtesy of AAA Foundation for Traffic Safety most often lead to crashes. 1. Speeding — This is the number one cause of crashes in Texas. This includes both driving above the posted speed and driving too fast for conditions. Increased speed leads to more severe collision and longer braking distances, and shortens the time a driver has to react. Studies have shown that novice drivers are more likely to drive at higher speeds than experienced drivers. 2. Failure to Yield Right of Way — This is the second leading cause of crashes in Texas. Examples would be trying to ―beat ‖ another car while entering a freeway, trying to "beat" a train at a crossing, or ignoring a yield sign on an access road. This daring behavior may be the result of impatience, aggressive driving, inattention, or poor judgment. 3. Driving While Intoxicated — This is the third leading cause of crashes in Texas. Younger people are often experimenting with alcohol during their early years of driving. This is a dangerous combination. Studies have shown that driving ability decreases as Blood Alcohol Concentration (BAC) increases. It is also evident that driving is impaired far below the BAC level that is considered legal intoxication. The risk of being in a fatal collision goes up dramatically as BAC increases. The risk is even greater for young inexperienced drivers. 4. Following Too Closely — This is the fourth leading cause of crashes in Texas. Studies have indicated that novice drivers tend to leave shorter following distances than experienced drivers. This is often cited as an example of a risk-taking behavior linked 5—8 to the higher frequency of crashes among young drivers. Space provides time– time to change speed or lane position to avoid a hazard. 5. Disregarding stop and go signal — This is the fifth leading cause of crashes in Texas. This could be from inattention or from trying to ―bea t‖ a light or ― roll‖ through a stop sign. These actions can lead to crashes because other drivers expect you to stop. 6. Improper Turns — Examples of improper turns would be turning wide in a right turn or cutting corners on left turns. Sometimes improper turns are caused by failure to control speed going into a turn. 7. Unsafe Passing — This involves illegal passing or passing without sufficient clearance. A lack of driving experience, or risk-taking could contribute to this problem. Taking unnecessary chances or risk is not the only cause of crashes. Distractions while driving can be just as deadly. Often drivers do not realize what they are doing is distracting them from the driving task. Typical distractions include: Changing the radio channel, CD or tape Dialing, texting or talking on the cell phone Passengers Pets Eating (especially when food falls in your lap) or drinking Smoking Reading a road map, directions, etc. Searching for an item in a purse, wallet, glove compartment, back pack etc. Having items slide off the front seat Engaging in intense or emotional conversation Putting on makeup or looking at yourself in the mirror Driving an unfamiliar vehicle without first adjusting the mirrors and seat, locating vehicle options (lights, windshield wipers or other vehicle controls). Risk Factors How to predict and analyze potential and immediate risk by categorizing risk factors into controlled, low, moderate, and complex risk. How reduced-risk driving practices respond to potential and immediate risk in controlled, low, moderate, and complex risk environments. Low Risk Environment. A low risk environment is usually limited to speeds under 40 mph having uncontrolled and controlled intersections in urban, suburban, and rural settings. Traffic flow volume in low risk environments should be at a minimum allowing time for the novice driver to identify risks through changes to line of sight or path of travel. Features Wide, clearly-marked lanes Break away sign support posts New design guard rails Protected left and right turn bays Banked roadways Crowned roadways Grooved roadways Curbs Side walks Risk Factors Inherent to Low Risk Environment: Line of sight restriction caused by houses, trees, bushes, etc. Path of travel restrictions caused by vehicles parked on the side of the road, toys in street, children playing in streets, etc. Pedestrians Animals School zones School buses Parks and recreation centers Children playing in driveways Complacency - Driver lulled into false security that environment will remain low A driver must be cautioned that a low or moderate risk environment one moment has a possibility of changing to complex at any moment, especially when children or pedestrians are present, traffic volume is increased, or traffic flow changes. risk Unexpected increase in and type of traffic flow Moderate Risk Environment is limited to speeds under 60 mph having controlled intersections in urban, suburban, and rural settings. Traffic flow is moderate, allowing time for the novice driver to identify risks through changes to line of sight or path of travel. Two way, one way, and multi-lane roadways are recommended for use in moderate risk environments. Features Wide, clearly-marked lanes Break away sign support posts New design guard rails Protected left and right turn bays Banked Roadways Crowned Roadways Grooved Roadways Curbs Side walks 5—9 Risk Factors Risk Factors Inherent to a Moderate Risk Environment : Lane blockages No gap in the traffic flow in which to make a lane change Traffic stoppages that could trap you in an intersection One or two way reversible lanes Shared left turn lane Yielding to pedestrians in the crosswalks Turns allowed from more than one lane Changing speed limits Increased traffic flow, especially at rush hours (morning, noon, and evening) Line of sight restriction caused by houses, trees, bushes, etc. Line of sight restrictions caused by buildings, billboards, stores, etc. Path of travel restrictions caused by vehicles parked on the side of the road, toys in street, children playing in streets, etc. Pedestrians. Animals. School zones and school buses Pedestrians waiting for city buses Light rail Commuter parking areas Local business Fast food restaurants Gas Service Stations Business driveways Parks and recreation centers Children playing in driveways Complacency - Driver lulled into false security that environment will remain moderate risk Unexpected increase in and type of traffic flow Complex Risk Environment is limited to speeds under 70 mph having controlled or limited access interchanges or intersections in urban, suburban, and rural settings. Traffic flow is heavy and many times unpredictable, which does not allow excessive time for the novice driver to identify risks through changes to line of sight or path of travel. Two-way, one-way, limited-access, and multi-lane roadways are recommended for use in complex risk environments. Features: 5 — 10 Wide, clearly-marked lanes Break away sign support posts New design guard rails Protected left and right turn bays Banked Roadways Crowned Roadways Grooved Roadways Clear highway shoulders Rumble strips New design median barriers Crash attenuators Risk Factors Risk factors inherent to Complex Risk Environments: Risk Factors — Merging Lane Risk Factors — Multiple Lane Roadway Heavy traffic Higher speeds—greater braking distances needed because it takes longer to stop Lack of a gap to merge Traffic slowing or stopping ahead Field of vision is narrowed Visibility problems ahead and to the side Highway hypnosis Velocitation effect (not realizing the actual speed of the vehicle is faster than what you feel) Risk Factors — Passing Passing is one of the most dangerous maneuvers a driver can attempt High speed passing on expressways adds to the danger Entering and exiting sometimes on the left Vehicles on shoulder reentering High volume of traffic on expressways increases the chances of collisions Passing may occur on the left or right Windy sections of the roadway Two vehicles changing lanes into same lane More than two lanes heading in the same direction present special search technique challenges Slow moving vehicles ahead ―Pack D riving‖ Tire Hydroplaning during wet weather conditions Risk Factors — Exiting Heavy traffic Short ramps Acceleration lanes High walls that may block visibility Traffic ahead on the ramp may slow or stop abruptly Risk Factors — Entrance Ramp Picking the wrong lane Traffic ahead and behind on the ramp Sharp curves on the ramp Visibility problems ahead and to the expressway Risk Factors — Acceleration Lane Amount of traffic in lane and on expressway Short acceleration lane Limited space ahead Actions of drivers ahead and behind ―Weave‖ lane conflicts Traffic on the exit ramp Short deceleration lane Very slow ramp speed Risk Factor — Highway Hypnosis. When driving over a long period of time, particularly on a rural expressway with little traffic, be aware of a condition known to drivers as ―h ighway hypnosis.‖ When traveling at high speeds for long periods of time, the driver may become hypnotized by constant staring ahead on the roadway, which may result in driving in a dulled, drowsy, trance-like condition. Risk Factors — Expressway Entrances 5 — 11 This is a dull or drowsy condition that can occur because of the concentration needed while driving long distances. Plan breaks and rest stops to combat highway hypnosis. Pull to a safe area for rest and sleep when Risk Factors How risk is processed differently by novice and experienced driver. How risk factors are predicted, analyzed, and minimized by employing Traffic Laws, Driver Preparation, Vehicle Movements, Driver Readiness, and Risk Reduction reduced-risk driving practices. How multi-task performances and distractions complicate predicting, analyzing and minimizing risk factors. timing divided attention tasks managing distraction utilizing a space management system that includes information processing It is also important to recognize that taking attention from the path of travel means the vehicle is moving on the roadway without the driver seeing where the vehicle is going or mentally processing any new information. Therefore, a driver should not increase risk by allowing any of the multi-task performances to become a distraction: Although risk-taking involves both novice and experienced drivers, statistics have shown younger drivers are more likely than older drivers to be risk-takers. Novice drivers often have less understanding and knowledge of risk awareness, especially in right-of-way, need to reduce speed (slow down), speeding, distractions, driving under the influence of alcohol or being a passenger with someone who has been drinking, improper turns, stop and go signals, passing, and following too closely situations. Studies have shown that younger drivers often believe they possess the ability to either properly assess the driving risks involved or to handle the potentially dangerous situations they encounter. Unfortunately, this misjudgment has resulted in younger drivers being overrepresented in motor vehicle crashes and fatalities associated with risk taking. A driver manages (predicts, analyzes, and minimizes) risk by utilizing risk reduction techniques including: applying knowledge and understanding of Texas traffic laws utilizing driver preparation procedures utilizing occupant protection and having passengers utilize occupant protection utilizing vehicle operation and control techniques utilizing attention techniques targeting line of sight and path of travel utilizing vehicle movements procedures utilizing reference points maintaining vehicle balance utilizing driver readiness techniques Targeting line of sight and path of travel Signaling Changing gears Checking gauges Checking mirrors Checking blindspot Monitoring speed Checking lane placement Checking traffic signs, signals, and roadway markings Checking street signs Checking roadway characteristics - Road and lane width, lane markings, roadway surface, shoulder condition and slope, curb type and height, hills and curves, intersections and interchanges, areas of limited visibility, location and type of structures adjacent to the roadway Checking weather conditions Monitoring intersections/interchanges Checking motorized and non-motorized highway users Photo Courtesy of AAA Foundation for Traffic Safety 5 — 12 Risk Factors Regrettably, we do not always do things in the right manner. How many incidents can be eliminated? Since there will always be factors working against you, what do you have working for you? A space management system is like an insurance policy. It can give you substantial protection for a small investment—just your involvement and understanding. Decision-making. Decision making is the most important skill used in driving. A driver operating in city traffic flow makes 50-60 decisions per mile. Most driving decisions are based on an internalized sense of procedures that tells us an action/decision is appropriate or not. These procedural decisions then become our habits, based on our experiences. These experiences can be positive and negative experiences. Complacency. Drivers easily get complacent about what has appeared to be a good style of driving. For example: Have you ever had to ride with someone who makes you very uncomfortable? The driver felt good about using inappropriate performances because for many years those same actions had led to success rather than failure. Performance. It is easy for us to do something incorrectly and not know it. We perform poor maneuvers at times and get away with them. Perhaps, after a while, we cease to see them as being poor driving procedures. Experiences. Drivers learn from positive experiences as well as from negative experiences. New drivers often learn by observation of other drivers. Their habits become specific behaviors which are mimicked by new drivers. Habits are difficult to change. Practicing specific behaviors and making judgments can lead to the changing of habits that take place on a procedural level. Guided Practice Concepts. A space management system will provide a background of good processes and judgment only if time is taken to practice. Resistance. There is an internal resistance to changing habits. The greater the resistance felt when attempting to use a space management system, the greater the need there may be to change the habits already formed. Habits. A driver’s current driving habits will, as the years go on, probably lead to sloppier driving which, of course, can get the driver into trouble. The reason for this is that it is easy for drivers to get positive feedback from negative behavior. Good Driving. Drivers tend to feel that whatever they do is good driving, provided there is no crash. When there is a crash, it is usually caused by the "erratic actions of the other driver.‖ In-Car Sessions. Practice should consist of 1530 minute sessions. The time must be spent actively getting feedback on what is being done in accordance with the space management system. If drivers are to benefit from the practice sessions, they need a clear concept of what to practice. 5 — 13 Guidelines for Risk-Taking Never risk more than you can afford to lose. Example is that of a young driver who breaks a specific traffic law or parental rule which will result in the loss of his license. The young driver might be risking too much. Another, would be in gambling. If you cannot afford to lose money, you should never wager that much. Do not risk a lot for a little. An example of this behavior might be ignoring a railroad crossing to save a few seconds or even minutes of time. The risk of a very severe crash or an expensive ticket is not worth that small amount of time savings. Consider the odds and your situation. Elements of driving that are beyond your control (actions of other drivers, weather, pedestrians, etc.) from those you do control (speed, use of alcohol, wearing safety belts, obedience to traffic signals, etc.). In dealing with risk, drivers should try to use those things they can control to help deal with those things they cannot. Factors Contributing to the Degree of Risk Factors Contributing to Degree of Risk Vehicle condition (condition of tires, suspension system, brakes, clean windshield, etc.) Weather (rain, ice, snow, glare, etc.) Driver condition (fatigued, impaired, distracted, angry, late, inexperienced, ill, etc.) Poor skill (poor communication, weak visual search skills, bad habits, etc.) Road condition (narrow, poor condition, obstructions, construction, etc.) Other users (children and other pedestrians, cyclists, trucks, wild and domestic animals, etc.) Underestimating risk (overestimating ability and vehicle capabilities, not wearing a seat belt, drinking and driving, not accepting responsibility for bad driving decisions - it's the other guy fault, being invincible, etc.) Emotions (angry drivers are more likely to take risks than happy drivers, passengers can affect driver emotions, driving to "cool off,‖ etc.) Distractions (smoking, portable technologies, pets, passengers, stereo systems, etc.) Underestimating the physical laws that affect driving (speed, gravity, traction, torque, inertia, kinetic energy, force of impact, centrifugal force, center of gravity, etc.) A number of studies of the relationship of Blood Alcohol Concentration (BAC—amount of alcohol in your blood) to fatal crash risk have been undertaken. As one would expect, the chance of being involved in a fatal motor vehicle crash increases as the BAC increases. When specific age group analysis is made, however, it is very evident that young drivers are at a much greater risk of being involved in a fatal motor vehicle crash. The risk for drivers age 16-19 is higher than for all other age groups at any BAC level studied. In addition, risk of death rises faster, as BAC levels increase, for this age group. For example, even at BAC’s of .015-.045%, the younger group was about two and one-half times as likely to be in a fatal crash, while the older group’s risk was no different than the sober level. A similar comparison for the .05-.079% BAC range found that the 16-19 age group’s risk factor was nine times greater than a sober driver while drivers over age twenty had a risk factor only two times greater. Drivers age 16-19 have forty times greater risk of being in a fatal crash at a BAC of .08-.099% than a sober driver. The same BAC range produces a risk of about seven times greater for drivers over age twenty. At the top side of the scale, BAC’s of over .15% produce extremely high risk for young drivers (420 times more likely to be in a fatal crash). It should be noted that in Texas, the average BAC at arrest is .16%.

Ways to reduce the risk factors related to multi-task performances. Risk factors and the top five contributing factors to crashes and fatalities in Texas by examining the motor vehicle crash and fatality statistics as reported by the appropriate state agency. Traffic crash and fatality rates of drivers in various age groups to the rates of novice drivers ages 15 – 17; Why novice drivers are over-represented in crashes, injuries, and fatalities including those involving speed, alcohol and other drugs, single vehicles, and off-road control loss crashes. Reduce risk by legally and responsibly predicting, analyzing, and minimizing risk factors. Another factor affecting visual attention is that the more driving experience a driver has, the driver is more likely to become a victim of seeing what ― they expect to see‖ (perceived risk) rather that what is actual risk. Usually a driver thinks things are not as threatening as they actually are. However, it is extremely important that a driver continually uses their eyes to check to the front, sides, and rear of the vehicle for the ―a ctual risk.‖ Top five leading causes of traffic fatalities in Texas as reported by the Texas Department of Public Safety are: Driving while intoxicated Speed - Under Limit – Unsafe Speed Over Limit Fail to Yield ROW to Vehicle Wrong Side-Not Passing The top driver errors committed most frequently by 16-year-olds in crashes are: Not attending to the path of travel Driving five mph or more too fast for conditions Trying to drive through a curve at too high a speed Inadequate searching at an intersection— pulling in front of cross traffic Involving the so-called victim’s lack of attention at an intersection and being struck by another driver Using improper evasive action—quick turn not made Failing to maintain visual lead Failing to see action developing at the side of the roadway Following too closely Willfully taking right-of-way Being distracted Most of these behaviors involved improper visual search, frequently combined with an inappropriate decision, i.e., speed in curves or for conditions and following too close. Some involved failure to take proper evasive action (i.e., simply steer out of danger rather than hard brake); some were the result of willfully dangerous behavior. Factors that reduce the effectiveness of risk reduction techniques include: Driver Conditions Distracted Fatigued Aggressive while driving Alcohol and other drugs usage Risk-taking Weather conditions Light Conditions Traffic conditions Roadway conditions Vehicle conditions Photo Courtesy of AAA Foundation for Traffic Safety 5 — 15 Factors that contribute to RISK The vehicle — Ownership responsibilities require that a vehicle always be in good working order. But there are times when a driver either waits too long or neglects to do vehicle maintenance. Factors such as worn or bald tires; poorly adjusted and/or worn brakes, broken headlights, worn windshield wiper blades, dirty windshield, etc. all can be risk factors leading to possible conflicts and crashes. Developing Habits and Judgment Experiences you gain will guide you in your decision making. Learning to drive means first learning the physical skills of driving (procedural tasks) and with extended practice refining these procedures until they develop into habits. As habits form, you will begin to feel more comfortable with the procedural tasks of operating a motor vehicle. Then through observation and instruction, you will begin to start applying decision-making skills (processing tasks) based on the space management system you are learning. The roadway and environment — Roadway and environmental risk factors include; roadway construction and maintenance; areas of restricted vision, such as intersections, hills and sharp curves; weather conditions, such as bright sun glare and shadows, wet slippery roads, and limited visibility brought on by adverse conditions. There may be times when you may feel resistance to the changes required to effectively apply the skills you have learned into a more structured method of driving. This internal resistance to changing habits is natural, but when changes are needed and you put them into practice, it will aid you in developing risk management skills. How does one determine how much risk is acceptable? Decision-Making is the most important skill used in driving. The driving task is fundamentally a thinking task, your hands and feet will do only what your brain tells them to do and, in turn your vehicle will respond to their input. A driver operating in city traffic conditions can often make 50-60 decisions per mile, most of them without the driver realizing a decision has been made. That is because most driving decisions are based on an internalized sense of procedures that tells us whether an action/ decision is appropriate or not. These procedural decisions then become our habits, based on our experiences. Risk Acceptance—Involves Knowledge about the potential for errors and the result of the consequences for your decisions. As mentioned earlier, you sometimes do not do things correctly, but with knowledge you can help reduce risk. Good seeing habits and your ability to manage space on the roadway are essential ingredients for reduced-risk driving. Drivers need visibility, space, and time to avoid possible conflicts and perform the driving maneuvers needed to be a safe driver. Risk Compensation—Involves recognizing potential errors or limitations and making appropriate adjustments to: Reduce speed to reduce errors Adjust lane position to reduce errors Use appropriate communication to reduce errors The structure of a space management system can help. You will very seldom be surprised by the actions of others that would require a critical high stress or evasive response if you watch for slight changes, make minor adjustments for best speed control and lane position, and use effective communication. Risk Management. To manage risk and to lower the probability of a conflict, drivers must perform driving tasks with reduced-risk results. In order to do this, the driver must develop social, physical, emotional, and mental skills. As you begin your driving experience, you will learn from both positive and negative experiences.

How to predict, analyze, and minimize risk factors by utilizing a space management system, such as "SEE iT—Search, Evaluate, and Execute in Texas." Space management system such as "SEE iT—Search, Evaluate, and Execute in Texas‖ while establishing vehicle operating space, line of sight, path of travel, lane placement, right-of-way, following interval, vehicle speed, and communication. Space management system, such as Search, Evaluate, Execute in Texas (SEE iT) to predict, analyze, and minimize risk. Space management system to safely interact with other roadway users including vulnerable roadway users. Reduce risk by legally and responsibly employing a space management system, such as Search, Evaluate, Execute in Texas (SEE iT) to predict, analyze, and minimize necessary to bring the vehicle into the most controllable situation. With a welldefined system for determining a good or poor situation, the driver can on a processing level, receive sufficient feedback to improve the procedural level of his/ her mental driving performance. Before moving the vehicle, the driver must search for the ongoing conditions, continuously evaluate the space/areas to determine which are open, closed, or changing in the driver’s line of sight or path of travel, and execute how much acceleration is best, what lane position to take, and decide whether or not there is a need for communication. As the driver proceeds, the speed and lane position selected should be determined by the changing conditions of the line of sight, path of travel, and target areas. Examples of changing conditions are: legal speed limits, roadway conditions, lane width, environmental conditions, lane selection, visibility, traffic flow, time of day, traffic controls, and weather conditions. Each of these conditions should have an influence on what speed feels comfortable, what lane selection or position is chosen, and how communication techniques are used. Developing a System. Drivers are more likely to see what they anticipate seeing, the more routine their driving experience becomes. A low level of risk expectancy makes a driver think that things are not as threatening as they actually are. A space management system is a way to organize information into meaningful categories so drivers can easily and quickly make good decisions. As a result, the driver may continue to operate in situations when conditions, on a processing or judgment level, should dictate to him/her that an adjustment in speed or lane position (time or space) is needed. Fortunately, the consistent use of a space management system can combat this low level of expectation. Therefore, to help new drivers develop safe driving habits, it is necessary to establish some guidelines on the processing level that will compensate for this lack of alertness and low level of awareness. Driving safely involves knowing all the available options and the willingness to use them. Otherwise, this low level of risk expectancy will lead a driver into not adjusting the speed or lane position that is 5 — 17 Orderly Visual Search Process Look Ahead — Do Not Look Down! Speed and Vision. As speed increases, the amount of information needed to maintain car position and detect movement also increases. The ability of peripheral vision to detect the motion of other objects is reduced when speed increases. Minor adjustments to the steering wheel occur in shorter time frames, causing significant or exaggerated vehicle movements. With higher speeds, the visual lead needs to increase to give: More time to gather information. Increased peripheral vision, giving the driver time to detect motion and decide an adequate response. More space between other vehicles and your vehicle, so abrupt responses are held to a minimum. The Visual Search Process. The first space management skill a driver must develop is an effective visual search. To search effectively, a new driver needs to know where to look, when, how, and what to look for, and how to evaluate if a potential problem could be a high risk or reduced risk situation. A visual search process is an organized pattern of focused eye movements scanning the path of travel and driving environment searching in a regular sequence for critical areas or conditions. An organized searching process starts from the visual lead area, which is 20-30 seconds from the front of the vehicle. Keeping the eyes focused farther away from the vehicle will allow the driver more time to make decisions. Targeting in the center of the path of travel at least 20 to 30 seconds ahead is critical to gaining as much information as possible from the driving scene. WHERE AND HOW TO SEARCH Where to search involves moving the eyes from near (inside and outside the vehicle - as close as the dashboard and mirrors) to 20 to 30 seconds into the target area to identify objects or conditions that could increase the level of risk. There are three forward search patterns that should continually be evaluated to gain control over the intended path of travel. To have effective control over the front zones drivers must also keep awareness over the rear zone which becomes the fourth search pattern. A systematic search can help drivers develop an effective searching pattern into habit. Such searching habits will provide opportunities to be mentally ahead of the vehicle and eliminate high stress, high risk situations. One example of a search pattern is: Look to the target area Search and evaluate the front zones in the 12-15 second range Search driveways and intersections for possible changes to the line of sight/path of travel Check the rearview mirror Evaluate the 4-6 second range before entering that space Look again to the 12-15 second range Check the 4-6 second range Check the rearview mirror Check speedometer and gauges If environmental conditions limit one’s line of sight to less than 20 seconds, adjust speed as appropriate and look to the furthest point possible. Determine an appropriate speed and position and identify an alternate path 12 to 15 seconds ahead if the planned path of travel should become closed or threatened. Searching also involves monitoring the immediate path of travel, four to eight seconds ahead, the instrument panel, and timely mirror usage to monitor traffic to the sides and rear. 5 — 18 Space Management System before searching to the target area, three or four seconds would be quickly consumed and the driver is not able to get mentally ahead of the vehicle. When to search involves timing and direction of the search pattern. When to search requires consciously looking to determine conditions all around the vehicle before initiating any maneuver. What to search for requires forethought and planning - To be effective when searching the highway and traffic scene, the driver must be looking for specific kinds of information. Simply stated, ― Theeyes don’t tell the brain what it sees—the brain tells the eyes what to look for.‖ If the brain is not programmed to look for specific information, the eyes simply scan the scene and primarily respond to the more colorful and/or moving objects. How to search involves looking in a systematic pattern of far ahead to near, as well as to the left, right, and rear of the vehicle; and, making efficient use of both central and fringe vision. Searching/Look To The Sides: When approaching any place where other cars, people or animals may cross the intended path, look to both sides. Don’t rely on traffic lights or stop signs. Always watch out for other drivers— they may run the light. Check to the sides for speed and lane position options. Identify the best speed and lane position options for existing conditions. Since the brain is limited in the amount of information it can process at any one time, a more effective method is to search for and classify information by category. Searching can be made easier by classifying topics into one of four groups: Searching/Look Behind: Check the traffic behind every time the foot goes to the brake. Know if somebody is tailgating, coming up too fast, or trying to pass. Most rear-end collisions are caused by vehicles following too closely. 1. Roadway Features Road and lane width Lane markings Roadway surface Shoulder condition and slope Curb type and height Hills and curves Intersections and interchanges Areas of limited visibility Location and type of structures adjacent to the roadway. 2. Signs, signals, and markings: Warning, regulatory, directional, and informational. 3. Motorized vehicles: Cars, trucks, tractortrailer rigs, buses, motor homes, motorcycles, construction/farm tractors, and other slow moving equipment and horse drawn equipment. 4. Non-motorized highway users: Pedestrians, bicyclists, and animals. Searching/Blind Spots: These are areas around the vehicle that are not visible in the mirrors. Enhanced Mirror (BGE) Settings help reduce the blind spot areas. Before making any move to the side, quickly turn the head to see if the blind spot is clear. Also avoid driving in someone else’s blind spot. It’s as important for other drivers to see you as for you to see them. Searching/Identify: Scan the road ahead for potential hazards such as a vehicle, pedestrian, animal, or situation that could force you to slow down, speed up, or turn. Make more aggressive searches when there are line-of-sight restrictions that may conceal a pedestrian or a bicyclist. A driver can look in, under, and around parked cars for feet, wheels, shadows, and movement. When done at the proper distance, pedestrians and bicyclists can be seen before they create a surprise. Would an airplane ever land on a highway? The immediate path is the space within 4-6 seconds of travel time. It is very important to acquire the skills to search all three ranges: the target area, the 12-15 second range, and the immediate path. The immediate path should only require an update of the conditions originally detected when evaluating the travel path. By looking only at the immediate path Be prepared for anything to appear on the roadway! 5 — 19 Space Management Communication is an exchange of information. To be effective communication must be clear and take place early enough for others to receive and act upon the information that was sent. Drivers can communicate with other highway users in several ways: through the use of turn and emergency flasher signal lights, brake lights and headlights; by lane selection and position of the vehicle within a lane; the use of hand signals, the horn and speed of the vehicle; the actions of the driver such as the use of a cell phone. Depending on circumstances one method may be more effective than another and at other times more than one method may be needed. Where to Stop. The pavement will tell you where the legal stop must occur: the stop line, the crosswalk, or before entering the intersection. Use a staggered stop (15 feet from the legal or safety stop) to give space for turning traffic entering the lane beside you. Few drivers realize that signal lights flash only one to three times per second and as a result the signal should be activated several seconds in advance of any planned move so that other highway users have enough time to see and interpret your intentions. This time/distance is typically well beyond the minimum distances required by the motor vehicle code. Searching into Turns. Turns and curves reduce your line of sight. Adjust speed before entering the turn. Before turning, turn your head and look into the turn before turning the steering wheel. Look through the turn to the exit. If you can’t see the exit of the turn – Slow Down! Searching Intersections. When approaching an intersection search 45 degrees to the front, left, right. While stopped, search 90 degrees – left/front/right. The sequence depends upon the conditions in the intersection. Search for line of sight and/or path of travel restrictions. Determine the point of no return (you will continue into the intersection) when you are 2 seconds from the intersection. Your speed will determine the distance from the intersection. The slower you approach an intersection, the more time you will have to decide if you can enter the intersection or you must stop. 5 — 20 Space Management System The Space Management System, SEE iT (Searching, Evaluating, and Executing in Texas — good to use while driving in all other states, too) consists of components that will allow the driver to manage time, space, and visibility. The space management system is easy to use and applies to all highway situations. EXECUTE appropriate adjustment(s). Carry out any alternative action needed that best fits the situation that has arisen. (Speed, lane position, space cushion, and communication method may all be required to reduce the risk.) The driver can change speed, change direction, or communicate. A driver’s options relative to speed control are: Projected path clear - maintain speed Projected path clear - increase speed Projected path threatened - off accelerator/ decrease speed Projected path closing -no alternate path/ decrease speed Projected path closed - controlled braking/ decrease speed The three-step process is to help change a driver's awareness from the procedural habit level to the process judgment level of driving. The three steps must be actively practiced to develop them into a decision-making process. All three steps will be used to illustrate line of sight and path of travel problems and solutions. Achieving the very best use of speed control, lane positioning, and communication is the most important goal in reducing risk. Using the three steps involved in space management and applying them to the six basic space areas (zones) around your vehicle will help you attain that goal. Considerations relative to communication including adjustment of position, speed, and use of signal devices are: Circumstances under which a driver should communicate Timing of the communication Method used to communicate SEARCH for objects or conditions. Searching means to scan the entire scene for anything that might come into your line of sight or path of travel. For instance, other roadway users or conditions in or adjacent to the projected path of travel that could increase risk. Included are vehicles; pedestrians; animals; restricted visual field; limited space to the front; sides and/or rear; and potential conflict points such as curves, long and/or steep downgrades; hill crests, railroad crossings, and interchanges. EVALUATE the projected path ahead for alternate paths of travel. You need to give meaning to what you have observed. Evaluate where the possible points of conflict may occur, what could happen and how it will affect you if does occur, and what alternative in path of travel and speed adjustments may be needed to prevent the conflict from occurring. Check to sides and rear for speed and lane position options. Maintain open space on at least one side into which the vehicle can be steered. Identify best speed and position options for existing conditions. Photo Courtesy of AAA Foundation for Traffic Safety 5 — 21 Space Management — Searching Searching 20 - 30 seconds ahead. Sometimes a typical driver search is only four to five seconds ahead of their vehicle. While adequate to avoid stumbling when walking, this short visual search leads to excessive braking, and adjustments of speed and position when driving. Development of an adequate visual search is difficult to master. However, it is the only way an individual can effectively assess a safe travel path, identify possible sightline changes well in advance, and determine appropriate speed or position adjustments. however, that a loaded tractor-trailer rig may require 10 to 15 seconds to stop under the same conditions. Searching 4-8 seconds ahead. Searching 20 to 30 seconds ahead and identifying an alternate path 12 to 15 seconds ahead into which the vehicle can be steered, can assist in avoiding most threatening situations. The driver must also monitor the immediate path, 4 to 8 seconds ahead. The 4 seconds ahead represents the following interval and the 8 seconds provide a safe stopping zone under most conditions. In heavy traffic, the old 2 second following interval provided time to steer, assuming the driver was monitoring the actions of the vehicle five units ahead, but was rarely sufficient time to safely brake to a stop. Searching 12 - 15 seconds ahead. By searching ahead 20 to 30 seconds and identifying an intended path of travel and possible alternative paths 12 to 15 seconds in advance, the driver has more time and space to exercise options. By looking as far ahead as possible and adjusting speed to the visual field, the driver has more time to identify potential problems. Early identification and assessment of objects and/or conditions provides time to adjust speed and/or position with awareness of adjacent, oncoming, and/or following vehicles. Depending on the driver’s level of attention to driving and where that attention is directed at a specific point in time, four to eight seconds should provide sufficient time to bring most passenger cars to a stop on a dry paved road or improved shoulder. It is essential to remember, 20 to 30 12 to 15 4 to 8 Although your field of vision allows you to see the front three zones around your vehicle, you will need to keep aware of the conditions in all six of the zones. This requires you to scan ahead of your intended path of travel. In our illustration we have outlined this area in blue from the beginning of your field of vision to the intended target area. You will need to perform an orderly search process in this area. The search process will consist of three ranges: 4 to 8-second range—Immediate Action Required! 12 to 15-second range—Escape Routes. 20 to 30 second range to the target area—Looking for open path of travel. 5 — 22 Space Management — Searching Three to Four Second Following Time. Gives the most control over the space directly in front of the vehicle. Reduce risk by creating as much space as possible. Adequate distance has many advantages: More time to adjust to traffic conditions reduced surprises More space in which to maneuver the vehicle Control of the space ahead of the vehicle Controlling Space to the Front and Rear. There are three ways to control space to the front. Time arrival to a given point by Adjusting speed Placement of the vehicle when stopping Controlling speed while in motion. Following Time. Following too closely is a primary causation of traffic collisions among all drivers. Time is needed to react to danger to avoid a collision. A reasonable following time may change as a result of road conditions, weather conditions, fatigue, drugs, inattention, or traffic conditions; and, even vehicles of different weights affect the ability to stop. The three to four second following time is the minimum following time under good driving conditions. Remember, how it works like this: Choose a fixed object such as a sign or tree ahead of the car in front of you. As the car ahead passes the object, count off three or four seconds (one-thousandone, one-thousand-two, one- thousandthree, one-thousand-four). If it takes at least three to four seconds before you pass the object, you have enough distance for a sudden stop. In bad weather, increased your following time by several seconds to give an extra All time and distance relationships are designed for the best driving conditions: A 2-second following time provides the driver time to steer out of problem areas at all posted speeds on a dry surface and brake out of problems at speeds under 35 mph. A 3-second following time provides the driver time to steer out of problem areas at all posted speeds on dry surfaces and brake out of problems at speeds to 45 mph. At highway speeds even a 3-second following time is inadequate when braking to a stop to avoid striking a fixed object if the vehicle following behind is a tractortrailer rig. In such instances, a stopping zone of 10 to 15 seconds may be required.) A 4-second following time provides the driver time to steer out of problems at all posted speeds on dry surfaces and brake out of problems at speeds up to 70 mph. It is important to note that many passenger car tires are not designed to steer out of problem areas at speeds beyond 75 mph. At speeds over 75 mph, high speed rated tires are required due to sidewall flexion at higher speeds and turning movements. 5 — 23 Space Management Controlling Space to the Rear. There are options for controlling your rear zones: Check the rear view mirror: After seeing a change to conditions ahead Before and after braking action While stopped in traffic Before and after making turns Before and after making a lane change The larger the vehicle in front of you, the more following distance you will need. Stopped at a Traffic Light. When you are the first driver at a red traffic light and the traffic light turns green, take two seconds to ensure the intersection is open by delaying moving until after you have searched the left, front, and right zones. Stopping Behind a Vehicle. When stopping behind another vehicle, a safe driving habit is to leave enough distance from the vehicle in front so that the rear tires are seen touching the pavement. This good habit may keep you from hitting the vehicle in front of you if someone crashes into the rear of your vehicle. It also allows room to go around a stalled vehicle without backing and causing a traffic hazard. Conditions Adjustments A. Is your mirror blind spot clear? Slow down or accelerate until you have a safe following interval for either your car or the other car and then change lanes. This applies to both A and B conditions. Your vehicle position usually determines which alternative you should choose. B. There may not be enough space in the next lane for your vehicle to move into. C. A vehicle in the lane you want to move into may be approaching at a speed greater than you are traveling. Wait until the vehicle passes and then proceed with the lane change. D. You may not be able to complete your lane change before entering an intersection. Wait. DO NOT change lanes in an intersection. Drive through the intersection first and then proceed with the lane change. There can be many other reasons to cancel or wait to make a lane change. SAFETY MUST ALWAYS COME FIRST. If there appears to be the possibility of a conflict, WAIT UNTIL THE WAY IS CLEAR. 5 — 24 Space Management When the planned path of travel is open, but threatening objects or conditions exist on both sides. When there are threatening objects or conditions to both sides of the path of travel, reduce speed, cover brake while in the area of reduced space, and maintain lane position one. Making Lane Placement Decisions. When space to the front is clear. When traveling in lane position one, search 20 to 30 seconds ahead along the planned path of travel and 12 to 15 seconds to the left and right frontal areas to identify planned and alternate paths of travel. Continually reassess the immediate path four (4) to eight (8) seconds ahead. If an object or condition adjacent to the projected path of travel reduces space to either side, check to the rear and side and move to position two or three as appropriate. When there is no following traffic. The absence of traffic to the rear provides the maximum level of control to the rear. It permits quicker and more abrupt changes of speed and/ or direction in response to changes in ongoing and oncoming traffic or other roadway users. When more than one object or condition adjacent to path of travel poses a possible threat. Having identified that the planned path of travel is open, determine which object or condition poses the greater risk and decide on change of speed and/or position appropriate to the situation. Depending on which object represents the more serious consequences; a reduction in speed and movement to lane position two or three is typically sufficient. Selecting a Safe Gap. Knowing how much space there is between you and other vehicles is critical. The ability to judge a safe gap is necessary any time a driver is joining with traffic or passing through an intersection. Enough time is needed to make speed and steering adjustments. The vehicle approaching from the left will be the most hazardous, since it will enter your path of travel before vehicles traveling from the right. Different size gaps are needed for different maneuvers. To judge a gap, estimate the speed and closing rate of the on-coming vehicles. A larger gap is needed to turn right than to cross an intersection. A left turn is more dangerous than a right turn because the vehicle is in the intersection for a longer period of time. When the planned path of travel is closed, but alternate paths are open. Having identified alternate paths of travel 12 to 15 seconds ahead and maintained an area into which the vehicle can be steered into at least one side, more time is provided to reassess traffic to the side(s) and rear and communicate intentions prior to adjusting position and speed. From a stopped position, to pass through an intersection with traffic moving at 30 mph the gap needed is: 5-6 seconds to cross a two lane roadway without interfering with traffic flow (look for vehicles almost a block away) 7-8 seconds to cross a four lane intersection 7-8 seconds to turn left (look for vehicles more than a block away) 6-7 seconds to turn right (look for vehicles at least a block away) When changing lanes look for a 4-6 second gap When the planned path of travel is closed and there is no alternate path. Having determined when searching 20 to 30 seconds ahead that there is no alternate path available 12 to 15 seconds ahead, immediately check to the sides and rear to detect the presence, location, size, and speed of any following vehicles. If present, flash brake lights to alert the following driver and begin to apply the brakes. Attempt to maintain forward motion while opening up the space ahead. If the distance ahead cannot be increased, brake to a stop while maintaining a gap to the rear. 5 — 25 Space Management Vehicle Distance Traveled Per Second. Vehicles travel at 1.467 feet per second. To determine how many feet a vehicle is traveling at a given speed two methods for calculating result in almost the same answer. Simple reaction time: the average is .75— ranges from .5 to 2.0 seconds Complex reaction time: the average is 2.5— ranges from 2.0 to 7.0 seconds Factors Affecting Response Time Perception time can be affected by: distractions, inattention, poor visibility, line-of-sight restrictions, etc. Reaction time can be affected by: fatigue, illness, medications, alcohol, age, etc. Formula #1 5,280 feet ÷ 60 min ÷ 60 Sec = 1.467 feet traveled per second 1.467 X 50mph = 73.3 feet per second Examples of response times: Formula #2 (For a more simplified calculation, but not precise, multiply speed by 1.5 feet per second) 2 seconds on dry surfaces — steer out of problem areas at all speeds or brake out of problem areas at speeds under 35 mph 3 seconds on dry surfaces — steer out of problem areas at all speeds or brake out of problem areas at speeds under 45 mph 4 seconds on dry surfaces — steer out of problem areas at all speeds or brake out of problem areas at speeds up to 70 mph 1.50 X 50mph = 75 feet per second Formula #3 (for the easier calculation). Take the speed, divide by 2, add the result back to the original speed. 50mph ÷ 2 = 25 25 + 50 = 75 feet per second Knowing how fast the vehicle is traveling can help drivers understand the limits of their ability to react and the vehicle to respond. Cut reaction time by covering the brake when a possible conflict is seen. Covering the brake is accomplished by holding the foot over the brake pedal. Most passenger car tires are not designed to steer out of problem areas at speeds over 75 mph. High speed rated tires are required because of sidewall flexion at high speeds and turning movements. Driver Response Time. Drivers need sufficient time to see a hazard, determine a safe response and time to take the correct action. Perception time is the amount of time it takes for you to see a hazard. Reaction time is the time it takes for you to act after you saw the hazard. The average reaction time is 3/4 second. The hands can respond quicker than the feet. Photo Courtesy of AAA Foundation for Traffic Safety 5 — 26 Space Management Reduced Risk Driving Decisions. When driving, 50-60 decisions are made per mile. Those decisions are based upon the ability to see and identify potential hazards. As traffic conditions are evaluated, the driver must be able to accurately predict If the hazard is moving toward you or away from you? If the traffic light is a stale green? If the zone will be open or closed? What lane position should you be in? Where will the other driver go? Is there more than one possible action? Where would your escape route be? Where will the point of conflict occur? Will the pedestrian enter the roadway? Is there is sufficient traction? How fast is the vehicle traveling? What other possible decisions could be made? fend) 2. Change Speed. Path of travel is open—maintain, increase, or decrease speed Path of travel is changing—off accelerator and cover brake Path of travel is closing—off accelerator, squeeze brake Path of travel is closed—controlled braking 3. Change Direction—some times the safest action is to take another route. Once a prediction is made, the decision must be made on the action you will take to avoid the hazard. Your goal is to perform (execute) the action with smooth precision. Drivers have three actions available; and, more than one action may be needed. Move to a different lane position to gain more space Change lanes Turn onto another street New conditions and situations are always present when driving. A driver must constantly question the present conditions. What speed selection feels most comfortable for each situation? What is the legal speed limit? What should the lane or lane position be? What is a good speed selection for this situation? 1. Communicate. To be effective, communication must be clear and early enough for others to perceive and react upon. Communication techniques include: Signals (turning, backing, hazards) Brake light (flash, slowing, stopping) Lane position (space management, turning intent) Horn (a light tap to warn, increase eye contact) Head lights (visibility, hazards) Hand signals (never intentionally of- What would be a high risk or poor speed selection, with little to gain? Each situation is different with changing conditions. The speed and lane position selected are usually based upon the legal limitations, the destination, and what is comfortable for the driver. Whatever the choices for speed and position, the space management system relies on looking for conditions that could cause less control over line of sight, and/or targeting area, and/or path of travel. Watch for changes 5 — 27 Space Management System There are five choices for lane placement without making a lane change. Most cars are less than six feet wide while highway lanes are 10 to 12 feet wide. This leaves four to six feet of space to the side without having to change lanes. Lane Placement: Lane placements 1, 2, and 3 are positions within a given travel lane. Lane placement 4 and 5 involve moving the vehicle so that the left or right wheels are straddling the lane line markers. Other options involve changing lanes or moving to the shoulder of the road. least one side 12 to 15 seconds ahead into which the vehicle can be steered and safely brake to a stop. Under conditions where there is no alternate path into which the vehicle can be steered, the only option is to reduce speed to increase the following interval. Anytime a driver moves into an area of reduced space with a vehicle tailgating, it is essential that the driver start reducing speed earlier. Slowing earlier and tapping the brakes to alert the following driver provides greater control over the vehicle to the rear. Controlling space to the front - There are three ways to control space to the front. The driver can time arrival at a given point by adjusting speed, placement of the vehicle when stopping, and controlling speed while in motion. To improve following interval under heavy but free flowing traffic conditions, take advantage of the tendency of drivers to travel in platoons or packs. Rather than driving in a pack, position the vehicle in the first or second lane from the right, behind the last vehicle in the pack and establish four second following interval. Now reduce speed by two to three miles per hour. Within a matter of seconds traffic will clear. True, faster moving vehicles in the next platoon will overtake and pass, but basically there will be many fewer vehicles to deal with at any one time. In the past, on multiple lane higher speed highways, faster moving traffic tended to travel in lane one, the lane furthest to the left. However, over the past few years there appears to have been a move away from such lane discipline, and weaving has increased between all lanes. This behavior obviously calls for increased vigilance of traffic to the sides and rear regardless of the lane selected. The purpose of an aggressive visual search is to better enable the driver to identify safe projected and alternate paths of travel. The vehicle must be positioned properly so that the driver has an adequate sight path. Maintaining an adequate sight path requires a following interval of at least four seconds. [The two second following distance rule was intended to provide time to steer, not stop]. At highway speeds even a four second interval is inadequate when braking to a stop to avoid striking a fixed object if the vehicle following behind is a tractor trailer rig. In such instances a stopping zone of 10 to 15 seconds may be required. Therefore one of the goals of the decision making process is to always attempt to identify an alternate path, an open area to at 5 — 28 Space Management System Basis for lane adjustment. Using the SEE system approach, lane adjustments are based on restrictions to the line of sight or to the intended path of travel. Assigning lane position numbers or colors to the basic positions within a lane allows the new driver to move to the position quickly and can be communicated more easily than asking the student to move over a little (Module 3). Each lane position has a reference guide to make it easily used. LP 1 is 2 -3 feet from left and right sides of lane, while LP 2 is within 6 inches of the left line, and LP 3 is within 6 inches of the right line. Straddle positions are to the left or right lines or edges of roadway. Other adjustments are lane changes and should be considered to the left or to the right. When the planned path of travel is closed and there is no alternate path. Having determined when searching 20 to 30 seconds ahead that there is no alternate path available 12 to 15 seconds ahead, the driver should immediately check to the side(s) and rear to detect the presence, location, size, and speed of any following vehicles. If present, flash brake lights to alert the following driver and begin to apply the brakes. Attempt to maintain forward motion while opening up the space ahead. If the distance ahead cannot be increased, brake to a stop while maintaining a gap to the rear. When the planned path of travel is open, but threatening objects or conditions exist on both sides. When there are threatening objects or conditions to both sides of the path of travel, reduce speed, cover brake while in the area of reduced space, and maintain lane position one. When space to the front is clear. When traveling in lane position one, search 20 to 30 seconds ahead along the planned path of travel and 12 to 15 seconds to the left and right frontal areas to identify planned and alternate paths of travel. Continually reassess the immediate path four to eight seconds ahead. If an object or condition adjacent to the projected path of travel reduces space to either side, check to the rear and side and move to position two or three as appropriate. When there is no following traffic. The absence of traffic to the rear provides the maximum level of control to the rear. It permits quicker and more abrupt changes of speed and/ or direction in response to changes in ongoing and oncoming traffic or other roadway users. When more than one object or condition adjacent to path of travel poses a possible threat. Having identified that the planned path of travel is open, determine which object or condition poses the greater risk and decide on change of speed and/or position appropriate to the situation. Depending on which object represents the more serious consequences, a reduction in speed and movement to lane position two or three is typically sufficient. When the planned path of travel is closed, but alternate paths are open. Having identified alternate paths of travel 12 to 15 seconds ahead and maintained an area into which the vehicle can be steered on at least one side, more time is provided to reassess traffic to the side(s) and rear and communicate intentions prior to adjusting position and speed.

At 50 mph it will take 6 seconds to pass a vehicle traveling at 40 mph. 3-Point Turnabout: 20-30 second gap in both directions When stopped in traffic wait 2 seconds before moving your vehicle – search the front zones. When you are the first one stopped in line at a traffic light, wait 2 seconds before moving when the light turns green. Search the intersection for red light runners. You will need to increase these times and distances for: Large trucks Campers Buses Heavy traffic Adverse road conditions 5 — 30 Space Management System Searching into a curve. Seeing the curve and/ or downgrade 12 seconds ahead as a front zone change or a limitation in the path of travel will cause less stress and give the driver more control because he/she will now test the braking capabilities and get the best speed and lane position to negotiate the curve. account of your tracking path. As you are more confident in the use of reference points, your fringe vision will be more comfortably and efficiently used. By searching into the curve you are able to immediately evaluate any problem to your LOSPOT at a time when you may need to avoid a surprise crash situation. If a driver notices that the front is closed to your path of travel (POT— space to the target ahead that your vehicle will occupy on the roadway) due to the red light and the stopped car. You can save fuel if you stop accelerating and use the energy of the car’s momentum. You should also apply the brake with light pressure. Looking 12 seconds ahead would enable you to see the right zone change created by the traffic that is pulling out of parking spaces and by the bus that is stopped or stopping in the right lane. The control you have of the front zone will be changed by the curve of the entrance ramp and by the traffic flow that will be coming from your left. Trees can cause a LOS limitation. After seeing a curve in the roadway, make a mirror check for rear zone awareness. Check the left, front, and right zones to know what your options are. To evaluate your POT, search into the curve before you turn the steering wheel. Search 12 seconds ahead for new LOSPOT changes. Looking for Problems. The problem most drivers have is that most often they don’t have problems. Think about that for a while. Do drivers really expects a problem over the hill crest or around the curve? For the previous 9,000 times going into the curve, there wasn’t a problem. Drivers feel comfortable going a little faster than they perhaps should, but still there is no problem. When the problem does occur, we get surprised. Curves and hills reduce a line of sight (LOS – sight distance from the driver’s eyes to the target at the end of the intended path of travel) You are unable to see what you are driving into; therefore, you cannot know how your POT is. Looking 12 seconds ahead into curves means to direct your eyes through the curve, trying to see to the end of the curve as soon as you possibly can. By looking through hills and curves, you are consciously looking to see if your POT is open or closed to your vehicle’s movement. For example: a car stalls while backing out of a driveway into our POT. So what’s the solution? We must see the curve and hill crest as a LOS change, then aggressively look for the actual POT available or not available to you. Basic Cornering. As you approach a curve, do your braking in a straight line. Remember the bit about the tire patches. If you’re braking at 1.05 Gs, and that is the limit of the tires, if you start to turn, something’s going to happen you don’t want to happen. As the driver turns to the apex, he/she should release pressure on the brake. If you were looking ahead, you would see the zone change to your LOS-POT created by the curve. Your LOS is closed. As you get closer to the curve, by looking into the curve you would be able to see the condition of your POT as early as possible. If the driver is still braking as steering is feed to the vehicle, he should release pressure in the same manner as he/she steers. This is called trailing brake and will allow the driver to control motion of vehicle into curve. The apex of the corner is the point at which your car is closest to the inside edge of the usable roadway surface. With most cars, the driver should use a late apex so that they can use the power sooner on the exit of the curve. While looking into the curve you will be using your central vision to see any changes to your POT, and your fringe vision should keep 5 — 31 Space Management System Managing Space—Multiple Lane Roadways Adjust the vehicle’s position and speed to road and weather conditions in order to provide time for braking, accelerating, and steering. Develop a minimal four second following interval when merging onto the roadway, changing lanes, and exiting the expressway area. Minimal steering inputs are needed to change lanes when passing, entering, or exiting. Excessive steering can lead to a loss of control at higher speeds. Move over one lane at a time rather than moving across multiple lanes. Visibility and time are key elements to performing a safe lane change. Make room for vehicles entering the roadway from an entrance ramp by changing lanes when clear. When another driver tailgates, it is safer to change lanes while keeping an adequate distance to the front of the vehicle. Maintain plenty of space when returning to the lane after a pass. Reduce speed when roadway narrows at tunnels, construction zones, and for larger vehicles. Be alert for cross winds when driving over bridges or through open mountain passes. 5 — 32 Space Management System—Scenario Review Vehicle Operating Space (Module 3). There are seven basic areas of operating space for a vehicle. Six of the space areas (zones) are around the vehicle, and the seventh or the central space is what your vehicle occupies. Our concern is for the six zones that surround the central area. This diagram illustrates the six zones which are visible to the driver in the central area. Each of the six zones around the vehicle is identified by number, name, and color. This is to help make the zone areas easier for you to understand and identify. Direction of Travel 3 1 Right-Front Zone (Maroon) Front Zone (Yellow ) 2 Right-Rear Zone (White) Central Space Area Left-Front Zone (Green) 5 Rear Zone (Blue) Left-Rear Zone (Red) 6 4 A zone refers to one of the six spaces around your vehicle. It is the width of a traffic lane and extends as far as you can see. A zone has three characteristics, it can be OPEN, CLOSED or CHANGING. OPEN — An open zone is a space where you can drive without restriction to either your line of sight or path of travel. CLOSED — The space or area is not available for the vehicle’s path of travel or there is a restriction to the driver's line of sight. An alternative path of travel must be developed. CHANGING — A worsening zone condition. It is often an open zone space that is changing to a closed zone. Line of sight and/or path of travel become restricted resulting in an area with additional problems or changes developing. New conditions are always presenting themselves when driving. A driver must constantly question the present conditions based on risk probability and potential consequences. There are many ways a driver can be involved in a crash. Most are a result from the driver's inability to control the target area, line of sight, or path of travel. Imagine you are the driver of the RED CAR. In this illustration you are driving 55 miles per hour in the center lane on a three-lane roadway. There is a motorcycle traveling 50 miles per hour and a blue car traveling 60 miles per hour in the adjacent right lane. Do you recognize the potential for a conflict? Target Area Line of Sight Path of Travel Direction of Travel Avoiding most problem situations requires you to apply the proper visual search techniques to the zones around your vehicle, evaluate what you have observed, and make the necessary adjustments to path of travel, speed, and target area. First, add zones to our illustration. We will apply a search of the overlaying six zones to see if we can get a better perception of the area or areas that could possibly develop into a space conflict. 5 — 33 Space Management - Scenario Searching: (Keep your eyes moving.) Look ahead to your target area range. This area should be clear of any obstructions. If a vehicle moves into your path of travel, adjust your target area to a new location and reestablish the path of travel with an appropriate following distance. In heavy traffic volume, try to maintain a minimum 4second following distance to ensure time to respond should a conflict arise. Check your left-front zone and your right-front zone in the 12 to 15 second range. Look for things that could obstruct your line of sight or path of travel (intersections, driveways, traffic control devices, parked cars, etc.) Use your mirrors (rearview and side) to check your rear zones. Give quick shoulder checks to check blind spots. Evaluate your 4 to 8 second range, this is critical space when you need to respond to a potential conflict that may arise. (Although it may not always be possible try to keep 4 to 8 second range area clear in all three of your front zones it is important to identify which of the six zones are open and which are closed in case of a conflict.) You will repeat this pattern continually as you move forward. Each time you look or glance at a zone, it should only take an instant, allowing you to scan all six zones within seconds, without distracting you from your original line of sight and target area. Searching using this pattern above will allow you to evaluate all zones in your path of travel well in advance of possible conflicts. In our next example, we can see how this search method applies. Evaluating — After searching and seeing a changing or closed space area, evaluate the conditions of the opposite space area before making a decision. Our path of travel appears clear, but the blue car approaching the motorcycle, is traveling at a faster speed, and consequently a possible zone change could happen. The motorcycle is in zone three and is also in the 12 to 15 second range. The blue car is also in zone three, but is in our 4 to 8 second range and closing in on the motorcycle which is traveling slower. DO YOU SEE the possible PROBLEM that could develop into a conflict? 3 5 1 6 2 4 5 — 34 Space Management - Scenario Executing — Based on your evaluation of the related space areas, make a conscious effort to communicate your intentions, and then execute the best speed and lane position adjustments that the situation may require. Whatever speed and position you choose, the space management system recommends looking for ways to compensate for ongoing conditions that could cause less control over line of sight, targeting area, and/or path of travel. In other words, the driver should closely monitor changes to the space areas in the front and to the rear of the vehicle. In our example, there are a number of different actions you could take to avoid a potential conflict. Let’s now conclude the scenario — You identified a possible conflict situation developing between you and the blue car. This conflict will happen because the blue car traveling 60 mph is going at a faster speed than the motorcycle which is traveling at 50 mph. In a few seconds the blue car must cross into your path of travel to overtake the motorcycle. (You must never assume the driver of the blue car knows you are there. You may be in the driver’s blind spot, the driver may be distracted, or the blue car’s driver may simply believe he/she has plenty of room, or that you will get out of the way.) Response - You noticed zone 3 is closed — with the possibility of zone one becoming closed as well. You need to adjust your speed and lane position to allow the 4-to-8 second range to clear. This action results in the motorcycle moving into the 20 to 30 second range in zone 3 and the blue car moving into the 12 to 15 second range of zone 3. The blue car started to change lanes upon entering zone one. You had prepared by adjusting your speed and lane position in the central zone. As the lane change occurred you had two options: slow down even more and allow the blue car to proceed into zone 1; or change your position and move into the open zone 2. Both options would safely avoid any conflict between red and blue cars. There are other possible choices you could have made. You must evaluate each situation that develops on its own merit, and make the best decision you can based on what you have observed. By watching for slight changes, making minor adjustments for best speed control and lane position, and using effective communication, you will very seldom be surprised by the actions of others. Therefore, high-stress or evasive responses may be minimized or avoided entirely. Our example had several easy solutions. Experienced drivers who have developed proper search patterns would have considered this a routine situation. Hopefully, this scenario raised your awareness of the need to always be diligent in your space management system by applying proper visual searches and utilizing zone control. 5 — 35 In-Car Progress Assessment In-Car Progress Assessment Tool located in Module 13: In-Car Instruction The student reduces risk by legally and responsibly utilizing an in-car progress assessment tools to evaluate and improve behind-the-wheel skill level (mastery equals 70% or above).
