Official Rules 2016
of the Euro Scooter Challenge IG member of DMV e.V
Issue: 03.03.2016
European Scooter Challenge 2016
These rules are valid for all races held as part of the European Scooter
Challenge 2016.
As such it shall therefore be a fundamental part of any individual rules of
the corresponding races within the ESC 2016.
I. General Terms
1. Entrants
Any person from the age of 18 may participate, provided the the entrants riding skills
have been scrutinised and a starting permit has been granted by the event manager. .
2. Vehicles
The vehicles shall comply with the rules commencing section II of these rules.
3. Entry and Entry Fee
Number assignment, registration of vehicles and rider, as well as pre-entry are to be
carried out online via: http://www.eurochallenge.de .
Vehicle acceptance, the binding entry and payment of the entry fee are carried out onsite. The amount of the entry fee will be defined by the organiser and announced
under : http://www.eurochallenge.de in a timely manner.
Late entries can be arranged with the organiser on an individual basis and at an
increased rate on-site.
4. Execution
Each official ESC race weekend will be carried out under following basic parameters:
• A minimum of 2 x 15 minutes practice. The best lap (?) time of these two practice
sessions will determine the start grid position in the first race heat.
• Two race heats are held in a 10 minutes + 2 laps mode.
• The grid position in the 2nd heat equates to the placing in the first heat.
5. Scoring System
a) Points System
• Each ESC race day consists of 2 heats
• The first 15 riders of each class are awarded points in every heat.
• The winner is awarded an additional point, i.e. 1st place = 16 points, 2nd place = 14
points, 15th place = 1 point
• In case of points tie in the day scoring the 2nd heat of the day counts more.
• For a championship title to be awarded in a certain class at least 3 races each with a
minimum of 3 riders within a season shall have been ranked. Riders are considered
ranked if they have been ranked in at least one heat of a race weekend in this class.
b) Drop Results
• 8 races per season count towards the ESC Championship.
• The drop results are adjusted according to the actual amount of races per season.
• Hence there is an absolute minimum amount of 4 race weekends without drop
results per season to establish a valid championship.
• If there are more than two drop results due to the amount of race weekends, two
drop results need to be on a single race day. The remaining drop results can be chosen
freely.
c) Points Entitlement
• A rider is awarded points in an ESC heat provided he/she is less than 3 laps behind
the winner of this particular heat, he crosses the finish line and if the race
management has not disqualified the rider for technical reasons or because of unfair
riding.
5. Assignment of Numbers
Numbers are assigned based upon the class the rider is starting in, hence the numbers
are generally 3-digit.
Example: In future an entrant in class 1 gets a number starting with 1xx, an entrant in
class 4 gets a number starting with 4xx.
This system will technically implemented into the Eurochallenge website until the
start of the new season.
The assignment of numbers will after activation be carried out solely via
http://www.eurochallenge.de
The respective race organiser can assign numbers on-site at an increased rate in
justifiable, exceptional cases
6. Race Accident Insurance
• Each ESC-entrant is obliged to have a race accident insurance.
• At the entry procedure each race entrant shall provide evidence of either a DMVmembership or proof of a personal race accident insurance
• Alternatively a day insurance can be taken out on-site via the DMV
7. Scrutineering – Parc fermé
After each ESC-heat the respective ESC organiser and/or the technical scrutineers
can send up to 5 vehicles per class to Parc fermé for scrutiny.
If a breach of rules is detected during the scrutiny, the respective rider will be
disqualified from the classification for the particular race day and no championship
points of the race day will awarded. The ESC IG reserves the right to impose
sanctions beyond the aforementioned.
Furthermore applicable in general: Each entrant of the ESC-races shall at any time
prove by themselves the compliance with the rules of the scooter to the technical
commission, if asked to do so.
8. Protest
A protest regarding the non-compliance of rules shall be submitted to the technical
commission in writing on the race day. A deposit of 50EUR shall be paid. The
protester will be refunded the 50EUR if the suspicion is confirmed, otherwise the
money goes towards the ESC IG.
9. General code of conduct / handling of infringements
- Grid line-up at re-start after race stoppage:
After completion of the the second lap the position in this lap equals the grid
position. If the race is stopped before completion of the second lap the start
shall be carried out according to the qualifying position.
- Handling of false starts:
At the re-start the causer of a false start shall start the race from the last grid
position. Whoever causes multiple false starts during a race day shall be
disqualified for the the whole race day. If several riders cause a false start the
above rules apply to each individual.
- Conduct during the warm-up lap:
During the warm-up lap no overtaking is allowed and the track may not be left.
Technical issues shall be reported to the race manager by means of a distinct
hand sign.
- Penalty for excessive relentlessness:
The ESC organisers shall have the right to impose time penalties or re-ordering
in the grid position to their sole discretion in case of excessive relentlessness or
unfair behaviour on the race track.
This rule applies from the first free practice until the last race of a race
weekend.
II. Technical Rules
Track specific noise emission regulations shall be generally complied with.
