● There will be 2 car heats, a powderpuff and the main event.

○ All cars that participate in a heat or the powderpuff are eligible to return for the main event.

○ The car qualifies, not the driver, i.e. a puff car can be driven in the main by a male driver as long as he has signed the waiver and entry form and must be declared upon registration.

○ Women can drive in the main event if they choose to do so.

● No one is allowed in the arena area during the event.

● Only one person will be in the car when participating in the event.

● Drivers must have an approved full face helmet. NO bicycle, football or half helmets allowed.

● Drivers will stop at the gate before entering the arena so officials can check and make sure helmets are secured and seat belts are on. If a driver is found to not be wearing a seat belt or not have their helmet properly secured, they will not be allowed to enter the arena until they put their seat belt on and secure their helmet properly.

● A seat belt must be worn AT ALL TIMES. (see seatbelt section)

○ If you fail to wear your seatbelt for the entirety of the heat or main event, you will be disqualified and forfeit any prize you may have won.

● Drivers may do a “HANDS-OFF” inspection of other cars.

● No intentional hitting of the driver’s door. The judge’s decision is final.

● In the event of a roll over, the event will be stopped until the vehicle is upright. ○ Roll-over cars will not be allowed to continue.

○ If the vehicle is flipped on its side, it will be the judge’s discretion if the vehicle is safe to continue.

○ If a car is disqualified in any heat for any reason, it is allowed to advance to the main event if the officials deem it safe to do so.

● All drivers will stop in case of fire, roll-over, or other emergencies. ○ Drivers must remain in the car unless declaring themselves out of the competition.

○ It is the driver’s decision to shut off the motor under these circumstances, unless directed otherwise by an official.

● No radio or cell phone communication allowed in the arena.

● Flags will be up during the heat and the main event until drivers take themselves out of the competition.

○ If you break your flag, you cannot reenter the action. If you break your stick or wave your flag in a heat, you are automatically out and forfeit your placement if there are still other cars on a timer. i.e. if there are three competitors remaining in action and you break your stick you will default to third place. If there are four you default to fourth, and so on

○ You will be given 2 flags upon passing inspection.

● All cars must be in continual action.

○ Cars cannot be out of action for 2 minutes or you will be told to pull your flag. Cars must make a hit every 2 minutes or be disqualified, meaning unassisted contact in forward or reverse under their own power. Rocking back and forth is not considered a hit. NO SANDBAGGING!

● Any car or driver the officials deem to be unsafe or a hazard will be ordered to stop and take themselves out of competition.

○ A car will not be allowed to compete if the judges find it to be unsafe prior to a heat or the main event.

● Most aggressive Driver will be determined by all officials and event staff! ● Judges decisions are final

● This really shouldn't have to be here, but drivers must stay seated in their seat for the entirety of the heat. Absolutely no standing up to fix something while you are competing. If a driver fails to stay seated, they will immediately be disqualified.

● MWFA cars will not be allowed in the main event.

● All drivers must refrain from intentionally pushing cars through logs/barriers. This creates a safety hazard for officials and emergency crews around the track. ○ If you intentionally push a car through/onto the logs/barriers, you will be told to break your stick for intentionally breaking rules.

○ If you are pushed onto a log/barrier and can not get yourself off, we will pull you off.

○ We understand accidents happen, but intention to push someone through the log/barrier is clear. Help us keep this event as safe as possible for officials and emergency crews so we can continue to have it.
