CACC motorsport regulations are periodically revised using a Rule Change Proposal process where suggested changes to rules and regulations are submitted by CACC members for review and approval by the CACC and its membership.
To propose a rule change, any licensed CACC member may submit a Rule Change Proposal prior to October 1 each year. Proposals will be reviewed for appropriateness and then presented for discussion and voting by discipline licensees at the appropriate motorsport discipline meeting.
Note that General Competition Regulations and changes relating to matters of motorsport safety are the sole purvue of the CACC Board of Directors.
