  • The first black flag will be a drive-through warning letting you know you have exceeded the time. The second black flag will be a two- (2) minute hold. The third black flag will be a five- (5) minute hold. The fourth black flag will result in a disqualification for that race, and the vehicle will be removed from competition for the rest of the day.
