This rulebook is designed as a guideline or quick reference tool to help you understand the rules that pertain to the Ditchbanger National at ERX Motor Park. All racers should be fully aware of the regulations set out in the rulebook and should be prepared to abide by them. Any questions concerning rules should be directed to the ERX Race Director.
