The Central Alberta Raceways (CAR) has no express implied warranty of safety resulting from publication of, or complaint with these rules. They are intended as a guideline for conduct of the sport and are in no way a guarantee against injury or death to spectators or participants.

Participants are expected to be alert to inherent hazards of Mud Racing competition and are expected to exercise good safety precautions and procedures.



The primary responsibility for the safe conduction and operation of Mud Racer in competition rests with vehicle owner and driver. The total responsibility for mud racing's progress is shared by everyone associated with the sport. Close observance of the standards set forth in this rulebook is an important fundamental. The standards set forth by the CAR will serve as guidelines based upon experience ands professional mud racing.


 RULES and Requirements 

Mud Racer's primary objective is to drive a 4x4 vehicle through a pit of mud as fast and as far as possible and become the overall champion. C.A.R affords every Mud Race an equal opportunity at the title. Mud racing competition consists of classes for vehicles used in everyday aspects of the street, to classes that are designed for the professional vehicle that is not driven on the street.  

Individuals compete against the clock in attempt to have the fastest time while driving through a mud pit. In order to allow each competitor the fairest start possible.

Time starts when the light turns green and stops when the vehicle crosses an electronic beam at the finish line. Individuals compete against the clock. Winners in each class are determined by the combined time from both days' runs (using the best 3 of 4). The fastest combined time determines the winner. In the event that the electronic timer fails, a rerun will be awarded. If a complete run is not made, a measurement to the front of the vehicle is used to determine the distance traveled. Winners in each class are determined by combined distance from both days' runs. The farthest combined distance is the winner.

 Distance and time are kept on all runs. In the event of a tie, the combined distance plus the combined time is used, with the fastest time determining the winner.

Distance and /or time are awarded to the vehicle, not the driver. A vehicle may only compete ONCE in any class.

All competing vehicles stage with the staging light and must come to a complete stop before breaking the start beam. Failure to stop will result in an automatic disqualification (DQ) for that pass. Staging time is the time it takes to be at the start line in your running order. Pit officials have the authority to decide on the eligibility of a particular run.

Competitors and their vehicles should be prepared to be on time for their run and be in the staging order. Reasonable staging time is at the discretion of pit officials. All vehicles must be pulled forward. Only exception is if a vehicle breaks down within the 1st twenty-five feet, the driver can opt to be DQ'd for the pass and be pulled out backwards.

Staging must be done under the vehicles own power.

Reverse at any time during a run is an AUTOMATIC DQ!! Once you have broken staging beam you can no longer back up.

Any vehicle that comes out of the pit or in contact with any equipment is DQ’d for that run.

If a vehicle starts at the lights before the green light and the red light comes up on the tree - you will be DQ’d.

Once a vehicle has ceased forward motion and been flagged, it is not permitted to move again.

Vehicles that dig unnecessary holes in the pit are automatically disqualified for that run.

Driver's hands must be visible to the flagman during hook-up.

In Non Nitrous classes, Pit officials check to ensure that Nitrous bottles are sealed and tapped off.

Any competitor found to be running illegal will forfeit all points acquired during current race year and be fined the amount of any race payouts won. Fines must be paid back to C.A.R prior to the competitor competing in the next high class for the remainder of the race year, if the vehicle meets the standard of the lower class the next year, the competitor shall be allowed to race in the lower class again.

Violation of any governed rule shall constitute a disqualification.
