ProMX
RULES AND REGULATIONS
These rules and regulations shall be used for the Promx events. From time to time circumstances and conditions will require modifications of some rules. Such modifications are at the sole discretion of ProMX Group race officials. It is the rider or guardian’s responsibility to know his limitations and to ride within those limitations and to know the rules. Never should a rider be allowed to compete when the rider is not 100% both mentally and physically.
Steward or Promoter is the owner or who is in charge of the event and how the event will be ran, changes of the event can be made due to weather or daytime hours and nighttime events.
Under any circumstances a rider must compete in the highest classification he has ever achieved with any recognized organization. A riders age on January 1st will determine his or her age for that years events. A rider may not return to a lower classification without Promoter/ProMX approval.
Once a rider moves to the next higher age class in competition, they may not move back to the lower age class.
No refunds or rain checks are given after Race day practice.
Rider must own or rent a MyLaps Transponder and be on his bike to be in any event or allowed on the track during a ProMx race. We do not require them for practice
Riders must compete with proper numbers on front number plates as well as both side plates. Any rider who does not might not get scored for the event with no protest.
Even if you have a transponder on your bike you still need numbers on your bike.
All flag signals must be obeyed immediately by all involved or concerned riders. A rider who disregards any flag signal may be excluded from the meet, incur position penalty, or suspension for an indefinite period of time by the Steward of the meet.

The method of starting will be at the discretion of the Steward/Promoter and/or Starter, to be determined at the beginning of the event.
The following regulations shall be enforced. Additional regulations of conduct for particular situations may be issued for specific meets and will be explained at the event.
Once the events start no one is allowed on the race track or infield except during the peewee (50cc) races One parent or guardian per riders no minors should be on the infield of the track during a race. Riders or Racers cannot ride or walk the track or infield after Moring practice starts.
All outside assistance, except that of course officials, is forbidden during any race escaped for the 50cc Peewee classes
Anyone found consuming an excessive amount of alcohol, will be asked to leave the event. Any rider found consuming ANY alcohol or any drug or smoking marijuana, will not be allowed to compete and will be asked to leave the event.
During any practice session, any race, or any time, it is expressly forbidden to ride or push any vehicle for any reason in the reverse direction of the course, unless so directed specifically by an authorized course official. A violation of this regulation can entail possible suspension.
Cutting the track inside the track markers or hay bales where the track is clearly marked will be up to the promoter on how may Positions will be docked from the rider and is considered cheating
Any machine found illegal, upon being protested, can lead to suspension of the entrant, his sponsor, and pit crew. All points accumulated upon suspension will be forfeited.
Any rider or member of a rider’s pit crew found racing a machine in the pit area will be subject to immediate disqualification from the meet, for the rider possible suspension. A special area may be designated by the Steward/ promoter of the course as a warm-up area.
All vehicles, bikes and carts must go slow in the pit area.
Rider caught jumping the start, or blocking off a starting gate or line will be subject to position penalty. If further violations occur, disqualification for the rest of the meet will be assessed by the starter or clerk of the course.
Anyone participating on the course without first being entered for the Race will be subject to disqualification and/or suspension. Must be signed up for the event to be on the track.
Rider or riders entering the course at any point other than the starting area for or during a race or practice session, is subject to disqualification from the days events.
For safety reasons, there are no practice starts allowed at the start line.
All riders are responsible for the conduct of their parents and pit crew. Suspension can be levied against any rider or pit crew member showing bad conduct on or off the course at any race or practice event.
The ProMx Steward/Promoter shall exclude immediately any rider who, in his opinion, is guilty of any foul, unfair or dangerous riding.
The competition committee of ProMx Group is empowered to settle finally, any appeal or dispute arising at this event, and a decision by this committee shall be final and binding on all parties.
Protest must be filed within 30 minutes of the posting of results of the class in question, and must be in writing. Protest fee shall be $300.00. Part of the fees will go to the company doing the teardown. If the protest is found valid, the rest of the fee shall be returned. If found invalid, the fee is forfeited to the body whose sanction has been issued. If parts are involved an amount will be declared by the Steward/promoter of the event. No fees will be given to a protested entrant, labor or parts, which is found to be competing on an illegal machine.
Written protest and fee must be presented to the Promoter/Steward of the event. In the case of a questionable protest where rules and regulations are not specific, a ruling will be made by the steward/promoter of the event.
There will be no protest allowed against the decision of the Steward/Promoter of the event.
Protests may only be made by a rider or entrant of a machine in the same class as the protested machine or rider.
Persons camping at any race meets must conform to all regulations and Rule set up by ProMX Group or raceway personnel must have permission to do so. Camping or overnight parking at any of the events is a privilege not a right Resects all rules. Maybe some camping fees
Riders and/or family and pit crew who direct foul and abusive language to an official of the sponsoring club, organizer, ProMx official, are subject to disqualification for the entire meet and additional penalties up to, and including, suspension by the ProMx Group.
If mail or Online entries are requested, they must be received by the Promoter by the deadline.

The Olympic Scoring method will be used in scoring motocross events. 1st Place = 1 points, 2nd Place = 2 points, and so on. The rider with the LOWEST total after all events are added together will be the winner. In case of a tie, the rider with the best score in the final moto will be the winner.
If a race or event is stopped because of an apparently injured rider, said rider shall not be allowed to re-enter that particular race or event unless allowed by the starter, referee or official. He may, however, enter other heats or events for which he is qualified.
If a rider, or riders, starts the moto but does not complete half the laps of the event, they will be scored as last place plus two (2) positions. If a rider, or riders, do not start the moto, they will be scored as last place plus three (3) positions.
Two (1) minutes only shall be allowed for a machine and rider to make the starting line at a closed course event after a call from the referee or pit steward. After this lapse of time, if not ready, the rider and machine are out of that moto only.
If a rider, or riders do not start an event they will receive no score for that event.
Motos may be shortened at the discretion of the Referee/Promoter for safety. When the motos must be shortened for other reasons, the riders shall be informed before the start of the shortened moto over the PA System
If a rider starts on the wrong gate drop in his moto he will be scored as last place.
Any motorcycle that complies with the regulations set forth in these rules may compete. Technical inspectors may exclude any motorcycle of which the construction, condition, or controllability is deemed to be dangerous. The major concern of ProMx Group and its officials is safety. It is the rider’s and his support crew’s responsibility to keep his machine in top condition at all times.
