If a competitor is deemed in violation of the spirit and intent rule he or she may be disqualified netting zero points for the day in the class of the DQ without the option of dropping that race from the season points total if applicable. 22 bonus points are awarded to each competitor that attends all 10 competition days of the scheduled Route 66 events.
