Participants are expected to be alert to the inherent hazards of mud racing and are admonished to exercise good safety precautions and procedures. (The word participant shall include any person directly or indirectly associated with any vehicle lawfully on the premises for the purpose of competition, including but not limited to owners, drivers, and crew members.)   Drivers under 18 years of age must have written consent from a parent or guardian and will need LSMR Committee permission to enter.   Courteous conduct is expected of all participants. Horseplay, mud wrestling, throwing objects, tampering with competitors' vehicles, or general bad conduct will not be tolerated.

Any driver or pit crew found to be under the influence of alcohol or drugs, regardless of the amount, will be disqualified and asked to leave.   The shut down area and starting line shall be clear of people and machines during each run. No spectators will be allowed at the starting line or at the end of shut down.   All drivers MUST wear D.O.T. approved helmets.   Eye protection (face shield, goggles, or safety goggles) must be worn in any vehicle that has an open windshield.   Driver restraining system required in all vehicles.

Fire extinguishers are Mandatory in Modified, Mod II, and Unlimited classes,  please ask for one if you do not have one. For Super stock its highly recommended to have fire extinguisher in vehicle.  Driver must notify race officials and provide their own fire extinguisher if they have a chemical preference.   If your vehicle becomes stuck during the race, do not continue to spin the tires and dig holes. If this is ignored you will be disqualified. Once a vehicle stops forward motion, the run ends and distance will be measured.   There will be a tech inspection on all vehicles. Random inspections will be made throughout the season.   A race consists of two heats. The driver with the lowest combined time for the two runs will win that class. In the case of a tie, there will be a run off for that position.   A foul will disqualify a driver from that class. The driver will not be eligible for trophies or prize money. A foul consists of: (1) leaving the lane to left or right side, (2) early or false start, or (3) an incomplete pass. A foul is determined by the race officials. The decision is final!

Trucks in Mod, Mod II and Unlimited may run twice per class with a different drivers. Trucks racing Mod may bump up  to Mod II without any changes to the truck. Trucks running Mod and bumping up to Unlimited need to change truck; aka… a tire swap and or use nitrous.
