 ATV Mud Pit & Mudda-Cross Rules


bulletFull Face DOT Helmets, boots and gloves must be worn during any Competition as well as long sleeve shirts and long pants.
bulletAll classes, except for the open class, will be determined by the manufacturer’s label and the number of cylinders in the ATV.
bulletHigh Lifter reserves the right to make rule changes or decisions as it sees fit to promote fairness in the competition. All decisions by High Lifter are final.
bulletAll entrants must sign a waiver in advance releasing High Lifter and sponsors from liability. A parent or guardian who will execute the waiver must accompany entrants less than 18 years of age. No one under the age of 16 may participate.
bulletNo late registrations will be accepted.
bulletIf a rider registers for the wrong class that rider will be moved to the appropriate class and given the opportunity to race. If a race unit exceeds a class then it will be bumped to the next highest class. If it doesn’t meet that class, it will be bumped to the next highest class. In other words, it will be allowed to run in the smallest class it qualifies for – not automatically raised to the highest class. No refunds will be given if the rider chooses not race.
bulletEntrants may enter any class that they are not disqualified from entering. In other words, a racer can race in their class or in a higher class. You cannot race down a class.
bulletFemales may enter any class for which their machine qualifies.
bulletEach ATV or RUV is limited to one class. The only exception to this rule is that if an ATV is borrowed to run in the woman’s class. If an ATV is borrowed for the woman’s class, she will not be able to compete in any other class, even if on another ATV.
bulletRiders must be at least 16 to enter High Lifter events.
bulletIn the event that any participant is observed operating his or her machine in an unsafe or unsportsmanlike manner they may be disqualified and excluded from competition or banned from future events.
bulletAll ATVs and RUVs entered in an event must have a means of attaching a tow rope to the ATV or RUV should it become disabled or stuck during the event.
bulletStarting line position is determined by computer randomization. The first rider generated for a heat will start the race from the left-hand lane. The second in the next position to the right. This process will be repeated for as many riders as are in the given heat.
bulletIf a rider commits a false start, (leaving the gate early) the rider will receive a warning and the race will be restarted. If a rider commits a second false start, this rider will be disqualified and the race will be restarted.
bulletBoundaries of the mud bog will be clearly marked with flags, stakes, and/or banners. Participants who partially leave the course with any portion of their ATV will be disqualified.
bulletAll bikes arriving to the starting line must be ready to race without any work being done to the bike. Work may not be performed on the bikes staged at the starting line.
bulletNo person other than incidental contact by other racers may touch the participating ATV/RUV during the race. If any other party touches the participating ATV during the course of the race, the rider will be immediately disqualified.
bulletParticipants may push their ATV if they become stuck. There is no one foot rule.
bulletAll occupants of RUVs must stay in the RUV cockpit throughout the race. If the RUV becomes stuck or disabled neither the driver nor the passenger may get out to push for safety reasons.
bulletEvery racer assumes full responsibility and liability for racing. Racing is a dangerous sport, even with all the safety precautions that are taken.
bulletParticipants should not consume any alcohol beverages, drugs or any contraband on the day of the competitions. Any participant found under the influence of alcohol or drugs may be immediately disqualified from the competition.
