RACING STRUCTURE:

If eight or less sign up in a 4-wheeler class, a traditional, two moto format racing and scoring system will be used. If there are more than eight registered in a 4-wheeler class. it will use qualifying rounds to determine who races in the Main. The number of qualifying heats and number of riders that transfer will depend on number of entries, and times and results from qualifiers and LCQ’s will determine staging in mains. Mains will be at least 10 minutes in length unless conditions warrant changes. The maximum number of 4-wheelers on the track at one time, or going to a main event is 8. If there are more than 8 in a race, and there is insufficient room for a single row start, a second row will be added and lower ranked riders, or losing draw riders will start there. Qualifying groupings will be determined by random draws.

Drivers MUST wear a helmet, eye protection, gloves and boots. Chest protectors are recommended but not required. 5-Point harnesses are recommended but NOT required for ATV classes.
