MESSAGES ON PAVEMENTS
(including bus lane treatments)
Special Note:
As of 1 January 2011, the RTA is adopting the Austroads Guides (Guide to Traffic
Management) and Australian Standards (AS 1742, 1743 & 2890) as its primary technical
references.
An RTA Supplement has been developed for each Part of the Guide to Traffic Management
and relevant Australian Standard. The Supplements document any mandatory RTA practice
and any complementary guidelines which need to be considered.
The RTA Supplements must be referred to prior to using any reference material.
This RTA document is a complementary guideline. Therefore if any conflict arises, the RTA
Supplements, the Austroads Guides and the Australian Standards are to prevail.
The RTA Supplements are located on the RTA website at www.rta.nsw.gov.au

9.1
General
This Section should be read in conjunction with Australian Standard AS
1742.
Words, numerals and symbols may be marked on pavements to guide, or to
convey warning or regulatory messages to drivers. They should be
elongated in the direction of traffic movement in order that they may be
legible at the maximum distance. However, it is important to note that the
benefit obtainable with increasing elongation diminishes if the distortion
ratio exceeds about 10:1.
9.2
Words and numerals
The dimensional proportions of letters and numerals should be as shown in
Figure 9.1. Following are the general principles:
9.2.1 On roads where speed is 80km/h or less
The height of letters and numerals shall NOT be less than 2.5 m in where
the speed is 80km/h or less. Any departure from this practice requires
special approval from the General Manger, Traffic Management.
A message should, if possible, be confined to one line. Where two or more
lines are required they should have a separation of one-half to one times the
letter height and the message should be arranged to read from top to
bottom.
9.2.2 On roads where speed is > 80km/h
The height of letters and numerals shall be AT LEAST 5m where the speed
is > 80km/h.
A message should, if possible, be confined to one line. Where two or more
lines are required, a separation between lines should be four times the letter
height and the message should be arranged to read sequentially, i.e. with the
first word nearest to the driver.

Application of messages for use on road
pavements
Refer to AS 1742.2 for the types and details of word messages which can be
used on road pavements. The following messages have variations or are
additional for use in NSW:
KEEP CLEAR
FORM ONE LANE (Used at merges)
BUS LANE, BL
BUS ONLY
BUSES EXCEPTED (Refer to Fig 9.10 for details)
TRANSIT LANE, T2, T3 and TL
Control of exclusive turning lanes is to be by means of pavement arrows. If
necessary the word ONLY may be used between arrows (see Section 10.5).
Where the message is an advance warning the word AHEAD should be
added at the end of the message if there is likely to be some confusion as to
whether the message applies at that point rather than at some distance
ahead. The word END never needs to be used.
Following are some examples of pavement markings associated with word
messages.
9.3.1 Rail X
Provision and layout of pavement markings and box markings and
signposting on the approaches to railway level crossings shall be in
accordance with AS 1742.7. However the KEEP TRACKS CLEAR
(G967-2) sign is to be used on both the approach and departure of the level
crossing in NSW.

9.3.2 Keep Clear
9.3.2.1
General
‘KEEP CLEAR’, pavement markings may be used on a carriageway or traffic
lane, when a traffic queue obstructs other traffic wishing to cross that
carriageway or lane (i.e. right turning traffic).
9.3.2.2
Use
'KEEP CLEAR' markings should be used to treat:
Unsignalised intersections, which are frequently blocked by traffic queues,
mainly on the approach to traffic signals or railway level crossings, or
Car park entrances which are frequently blocked by traffic queues, or
Emergency vehicle station accesses, which may be blocked by traffic queues
9.3.2.3
Warrants for use
When considering the use of 'KEEP CLEAR' pavement markings, the
following must be observed:
The markings should only be provided where right turning vehicles are
prevented from entering or exiting the side street or car park (i.e. crossing
the queue) and subsequently cause traffic to queue back through a signalised
intersection, or where the waiting right turning vehicle causes a road safety
problem due to the road geometry.
The markings must NOT be provided to allow vehicles to turn left from a
side street or car park. 'KEEP CLEAR' pavement marking is regulatory and
thus a left turning vehicle would be committing an offence if they joined the
queue by entering the keep clear area. In this situation the soft option of
erecting an advisory 'DO NOT QUEUE ACROSS INTERSECTION
(G9-237) sign should be considered.
9.3.2.4
Restrictions
Following the decision to implement 'KEEP CLEAR' markings at an
intersection, the right turn movement out of the side street needs to be
considered. If this movement is considered to be unsafe due to road
geometry, traffic volumes or especially sight distance restraints caused by
9-4

the queue, a limited No Right Turn ban from the side street should be
considered.

9.3.3 Bus Lanes and Bus Only Lanes
9.3.3.1
(a)
General Specifications
Definitions
A ‘Bus Lane’ is a reserved lane predominantly for the use of public buses,
however, taxis, HC plated hire cars, motorbikes and bicycles can also use a
Bus Lane.
A ‘Bus Only’ lane’ is a reserved lane for the use of public buses only.
Note: A public bus is defined as a coach.
A coach is:
(a) Constructed principally to carry persons, and
(b) Equipped to seat more than 8 adult persons, and
(c) Used to convey passengers for hire or reward or in the course of
trade or business.
Emergency vehicles and NRMA patrol vehicles are granted an exemption to
use a Bus Lane during the course of attending an emergency. Vehicles under
the direction of the RTA can also use a Bus Lane to conduct emergency
maintenance or traffic surveys.
(b)
Types of Signs
Regulatory signs are required to define the start and end of a Bus Lane or
Bus Only Lane. In certain circumstances pavement text may be used in lieu
of signposting. Lane definition is enhanced by the use of pavement text and
colouring.
R6-234 series signs are to be used to indicate the start and end of a Bus
Only Lane. Where the length of the bus only lane is too short for signs then
pavement marking (BUS ONLY) at the start of the lane is sufficient and
legally enforceable. However it is important to note that pavement markings
end at the next intersection.
R6-235 series signs are to be used to indicate the start and end of a Bus
Lane. Where the length of the bus lane is too short for signs then pavement
marking (BUS LANE) at the start of the lane is sufficient and legally
enforceable. However it is important to note that pavement markings end at
the next intersection.
9-6
Version 1.1
UNCONTROLLED WHEN PRINTED
Delineation – Section 9 Messages on Pavements
In general terms bus lane and bus only lane signposting must be located
either adjacent to or above the Bus Lane or Bus Only Lane. Where this is
not possible then supplementary plates (R6-234 and R6-235 series) must be
used with the regulatory signs to identify which lane they apply to.
(c)
Types of Pavement Markings
L6 lines (35m mark 1m gap) are marked to separate the Bus Lane and Bus
Only Lane from the adjoining lanes.
In certain circumstances C1 lines (1m mark 3 m gap) may be used in bus
lanes 100m prior to the approach to an intersection to indicate where the
lane may be entered by traffic about to turn from the lane.
For dimensions and pattern of these lines, refer to Section 4.
Pavement messages for Bus Lanes or Bus Only Lanes are installed according
to the principles given in 9.2. In Bus Lanes where intersections are frequent,
the alternate pavement marking BL (short for Bus Lanes) may be used.
Red coloured pavement overlay or red bitumen for Bus Lanes and Bus Only
Lanes must be installed in accordance with Section 3.4.
Details of Pavement text are given in Figure 9.3.
Figure 9.3: Pavement Text (Speed Limit ≤ 80 km/hr)
Note
The height of letters and numerals shall be AT LEAST 5m in rural
areas (speed is > 80Km/h). The separation between lines should be
four times the letter height and the message should be arranged to
read sequentially, i.e. with the first word nearest to the driver.

9.3.4 Details of Bus Only Lanes
9.3.4.1
Warrants for Use
Bus only lanes must be used on the approach to all B-signals.
Bus only lanes must not be used across driveways, non-signalised
intersections, left slip lane entries or non-kerbside lanes which require
drivers to cross the lane to access an adjoining lane.
All bus only lanes must have red pavement. The use of red pavement is to
finish 10m before the stop line. For short lengths e.g. adjacent to turn
islands with left turn slip lanes, the red may be laid up to the stop line.
The road rules allow a bus in a Bus Only lane at an intersection with Bsignals, to make any turn when the B-signal is not red. Therefore this must
be considered and treated if necessary.
9.3.4.2
Messages on pavement
Pavement Message (BUS ONLY) is to be placed in the bus only lane adjacent
to both the first Bus Only Lane sign and each subsequent large repeater sign.
Additional BUS ONLY pavement messages may be used where it is
considered that they will add to the operational effectiveness of the lane
(e.g. where non-compliance is a problem). Typically these additional
markings are to be no closer than 50m apart in built up areas and 250 m for
motorway conditions.
Pavement messages (AM, PM, AM+PM or 24HR) shall only be used with
BUS ONLY pavement messages where it is considered that they will add to
the operational effectiveness of the lane. When used the markings shall be
placed after the BUS ONLY message. Pavement messages (AM, PM, AM+PM
or 24HR) should not be used on new lanes where no operational
characteristics apply. It is to be assumed that the standard signs and
markings will be sufficient.
Where the movement of buses requires restricting at an intersection (e.g.
no right turn), then pavement arrows are to be placed in the bus only lane
in the normal manner.
Where it is intended that other vehicles are to turn from the adjoining lane
because they cannot use the Bus Only Lane, pavement arrows must be
placed in the adjoining lane in the normal manner to permit the turn.

9.3.4.3
(a)
Treatments of Bus Only lanes
Where the bus only lane is the kerbside lane
L6 lines (35m line 1m gap) are to be used as the marking between the bus
only lane and the adjoining lane.
Refer to Figure 9.4.
(b)
Where the bus only lane is adjacent to an island
L6 lines (35m line 1m gap) are to be used as the marking between the bus
only lane and the adjoining lane
Where the bus only lane is at the end of a left turn lane, a C1 line (1m line
3 m gap) is to be used across the start of the bus only lane. In addition, as a
minimum, the final left turn pavement arrow on the approach is to exempt
buses. Consideration may also be given to placing the exemption text at the
first arrow in the left turn lane if it is considered that it will add to the
operational effectiveness of the lane.
Refer to Figure 9.4.
9.3.5 Details of Bus Lanes
9.3.5.1
Warrants for Use
Bus lanes can be used across driveways or non-signalised intersections.
All bus lanes must have red pavement. The use of red pavement is to finish
10m before the stop line at signalised intersections and adjacent to the side
street kerb line at unsignalised intersections. For short lengths e.g. adjacent
to turn islands with left turn slip lanes, the red may be extended up to the
stop line.
The red pavement is then to recommence after the intersection. In the case
of a signalised intersection this shall be after any marked foot crossing and in
the case of an unsignalised intersection adjacent to the side street kerb line.
9.3.5.2
Messages on pavement
Pavement markings (BUS LANE) are to be placed in the bus lane adjacent to
both the first Bus Lane sign and each subsequent large repeater sign.

9-9
Delineation – Section 9 Messages on Pavements
Pavement markings (BUS LANE) are to be placed on the departure side of
all intersections.
Where intersections are infrequent then additional pavement markings (BUS
LANE) should be installed at 100m intervals in built up areas and 250 m for
motorway conditions.
Where intersections are frequent, closer than 100m apart the number of
pavement markings may be reduced, or the alternate pavement marking (BL)
may be used. However, a driver entering a road from a side street should
never travel more than 100m before reaching a large regulatory sign or
pavement marking.
Pavement messages (AM, PM, AM+PM or 24HR) shall only be used with
BUS LANE or BL pavement markings where it is considered that they will
add to the operational effectiveness of the lane. When used the markings
shall be placed after the BUS LANE or BL message.
Pavement messages (AM, PM, AM+PM or 24HR) should not be used on new
lanes where no operational characteristics apply. It is to be assumed that the
signs will be sufficient.
Where the movement of the bus requires restricting at intersections (e.g.
no right turn), then pavement arrows are to be placed in the bus lane in the
normal manner. [Note: These pavement arrows will also apply to motor
vehicles.]
Where drivers are turning left from the second lane due to ignorance of the
law, pavement arrows may be used in the bus lane and second lane to
indicate the permitted movements.
9.3.5.3
Treatments of Bus Lanes
(a) Where the bus lane is the kerbside lane with no left turn slip
treatment: (i)
Signalised intersection approach
L6 lines (35m line 1m gap) are to be used as the marking between the bus
lane and the adjoining lane
Where drivers are turning left from second lane due to ignorance of the law
and use of pavement arrows has not helped, the C1 lines (1m line 3m gap)
may be marked for 100m on the approach to the intersection.

crossing.
Refer to Figures 9.5 to 9.9.
(b) Unsignalised intersection approach and departure
L6 lines (35m line 1m gap) are to finish adjacent to the red pavement on the
approach and are to recommence adjacent to the red pavement on the
departure of the intersection.
Where no TF line (Stop Line) or TB line (Give way line) exist on the side
street, a TB line may be installed between the bus lane and the side street if
it is considered that vehicles are likely to intrude into the bus lane.
C1 lines may be marked for 100m on the approach to an intersection to
indicate where the lane may be entered by traffic wanting to turn from the
lane, when the use of pavement arrows has not improved non-compliance
to the road rules. Refer to Section 9.3.4.2.
Refer to Figures 9.5 to 9.9.
(c) Where the bus lane is the kerbside lane with a simple left
turn slip treatment
(i)
Signalised intersection approach
L6 lines (35m line 1m gap) are to be used as the marking between the bus
lane and the adjoining lane.
A C1 line (1m line 3m gap) is to be used across the left turn slip exit.
C1 lines (1m line 3 m gap) may be marked for 100m on the approach to the

Where the length of the bus only lane is too short for signs then pavement
marking (BUS ONLY) at the start of the lane is sufficient. End pavement
markings are not required, as the bus only lane automatically ends at the
next intersection.
R6-234 series signs are to be repeated every 500m.
Where the bus only lane is part time, parking reminder signs (R5-310 series)
are to be placed above every permissive parking sign along the length of the
bus only lane or every 35 m in built up areas without parking restrictions.
9.3.6.2
Bus lanes
R6-235 series signs must be used to indicate the start and end of the bus
lane.
R6-235 series signs are to be installed approximately 50m on the departure
side of all major intersections.
R6-235 series signs are to be repeated every 500m where major
intersections are infrequent.
Where the bus lane is not the kerbside lane either the R6-235 series signs
are to be located directly above the lane or the R9-208 or R9-209 series
supplementary plates (diagrammatic lane arrangement signs) are to be
placed below the R6-235 series signs.
End signs are not required where the lane type changes (e.g. where a bus
lane changes to a bus only lane). In this situation the first new sign type acts
as both the end and start sign.
Where a lane changes type merely by signposting, an AHEAD sign should be
used 50m prior to the first new sign type.
Where the length of the bus lane is too short for signs then pavement
marking (BUS LANE) at the start of the lane is sufficient. End pavement
markings are not required; the bus lane automatically ends at the next
intersection.
Where the bus lane is part time, parking reminder signs (R5-310 series) are
to be placed above every permissive parking sign along the length of the bus
lane or every 35 m in built up areas without parking restrictions.

A square patch is installed on the road pavement adjacent to all school zone
(R4-230 or R4-235) signs and school bus stop zone (R4-232) signs installed
on the left hand side of the carriageway.
The pavement marking shall be two part cold applied plastic or
thermoplastic material, conforming to RTA specifications 3360 or 3357
respectively.
The pavement marking shall not have retro-reflective
properties, however, the skid resistance properties shall be as per the
Australian Standard AS 4049.2.

A transit lane can be to the left of, right of, or between other traffic lanes.
However, for enforcement reasons, it is preferable that a transit lane be to
the left of other traffic lanes.
Any motor vehicle may enter a transit lane for up to 100m before making a
legal turn to the left, or right, from a transit lane.
Examples of transit lane treatments are shown in Figures 9.16 to 9.21.
9.3.10.2
Signs
Position transit lanes signs:
(a)
To the left of a transit lane that is in the left lane, see Figures 9.16 and
9.17
(b)
To the right of a transit lane that is in the right lane, see Figure 9.18
(c)
Above a transit lane that is between other traffic lanes, see Figures
9.19 to 9.21.
Where the transit lane is between other traffic lanes, all efforts should be
made to place signs above the lane at 500m intervals. If this is not possible
then lane usage supplementary plates can be used with the Transit Lane
signs, see Figure 20.
Times of day shown on transit lane signs are standard. Do not use other
times without approval from the General Manager, Traffic Management.

Use Transit Lane signs as follows:
Start signs
Reinforcement signs
Use the above signs as reinforcement signs between "start" and "end" signs.
Firstly, at about 50m beyond each major intersection, then at about 500m
spacings for intermediate locations.
Where there are no major intersections between "start" and "end" signs
erect them at about 500m spacings for intermediate locations.

Use only lane line type L1 to determine a transit lane.

Pavement messages
For speed zones of 80 km/h or less, letters and numbers should not be less
than 2.5m high with longitudinal spacing equal to letter or numeral height.
For speed zones greater than 80 km/h the spacing, letter and numeral height
may need to be at least twice that for lower speed zones.
See Figure 9.1 for letter and numeral details.
For AHEAD, and AM + PM pavement messages reduce the letter or
numeral size up to 75% so these messages fit within the lane width.
