(1) Pit apparel: Persons less than 16 years of age and pets are prohibited in the Signal Area. Pets in the paddock must be on a leash or properly contained. Shirts must have a collar. Open-toed shoes, cut-offs and sleeveless shirts/tank tops are not permitted.
(2) Assistance: Outside assistance on the course is forbidden, except by corner workers or officials. In motocross, Supercross and Arenacross, assistance is allowed at the starting gate up through the first turn (at the start of the race only).
(3) Minimum motorcycle weights: 250 motocross class: 194 pounds (two-stroke)/212 pounds (four-stroke); 450 motocross class: 212 pounds (two-stroke)/220 pounds (four-stroke). Weight limits must be met after qualifying and after a race. The chief technical inspector may require a motorcycle be cleaned of excess mud or dirt before weighing. The official AMA scale will be available before qualifying and during the races for weight checking. No fluids may be added to the motorcycle, except water to the engine cooling system. The fuel must be drained from the fuel tank. A ballast attached to the motorcycle is not permitted.
(4) Race schedule: The race program will consist of two practice sessions per class. The first session will be free and a timed qualifier; the second session will be a timed qualifier only. Timed qualifying will be used to determine the order in which riders choose their starting position. Starting positions for the riders’ second National moto will be based on the riders’ finish in the first National moto.
(5) Throwing goggles: Riders and crew are prohibited from throwing any rider apparel or any other similar items into the spectator areas, particularly during podium activities.
(6) Audio/video devices: Riders are prohibited from using any personal audio listening device while operating a vehicle on the race course. The use of any on-board or helmet-mounted video recording device is prohibited, except upon approval by MX Sports.
(7) Start procedures: There will be no grooming in front of the starting gate by riders or mechanics. Grooming may be done behind the gate provided no shovels, tools or other implements are used. Watering of starting lanes by riders or crew is prohibited. Ten minutes prior to the start of the race, riders will be released for the sighting lap. The sighting lap is optional. Riders may receive repairs in the signal area during the sighting lap. Four minutes prior to the start, all riders must have completed their sighting lap and reentered their position on the starting gate. Once the motorcycle enters the staging area and is called to the starting line, the motorcycle will not be permitted to return to the paddock. If the motorcycle is removed from the staging area after this point, the rider will not be permitted to start the race. Riders may not exchange gate positions with other riders.
(8) Intravenous hydration: At no time during the event may a rider receive any type of intravenous hydration, unless such hydration is deemed medically necessary by medical personnel as a result of an emergency medical situation (i.e., heat stroke) encountered by the rider during, or as a result of participating in, any practice, qualifier, moto race or other activity in the event. Once a rider receives such hydration during the event, the rider will not be permitted to compete in any further event activities, including, but not limited to, any further practice, qualifier, moto race or other activity in the event, unless and until the rider is released by the medical personnel who treated the rider for the specific emergency medical situation at issue. Any rider who has received medical treatment from the event medical director, and where such treatment includes the recommendation that the rider be transported to an emergency medical treatment center, that rider shall be prohibited from competing in any further practice sessions or motos at that event.
(9) Disciplinary action: The following offenses will be subject to disciplinary action by AMA Pro Racing: Falsifying one’s age. Competing under a false name. Knowingly engaging in any race in which the result is “fixed.” Offering or accepting a bribe to circumvent AMA Pro Racing rules. Engaging in a rider boycott. Any unfair practice, misbehavior or action detrimental to the sport. A physical or verbal attack on an AMA Pro Racing official. Failing or refusing to submit to drug testing. No rider may, at any time, ride in such a manner as to endanger life or limb of other riders, officials or the public. Any rider or official discovered to have a measurable blood alcohol content during a professional racing event shall be barred from the event.
(10) Breaking ties: In the event of a tie for the championship, the winner will be determined based on the number of race wins during the series. If the tie remains, the number of finishes of second, third, etc., will be tallied until the tie is broken. If the tie continues to remain, the final moto finish of the last event will determine the champion. In all other cases of ties for championship positions, the final race finish at the last event will determine the final position in championship standings.
