The following rules and regulations supplement the CMRC Amateur Competition Rules, and are solely applicable to the Alberta Dirt Riders Association.

The rules in the 2008 CMRC Competition Rulebook are not the governing rules of the ADRA ATV racing. The ADRA does not have enough entries in the ATV classes to observe all the classes and rules as they are printed in the CMRC rulebook. The ADRA has amended and adopted ATV rules of their own to accommodate the ATV racing population in Alberta.

These rules apply to the Alberta Provincial and Southern Alberta Series only and are in addition to all pertinent race day rules and regulations outlined previously in the rulebook.
