General Motor Racing Rules - Applies to all series:

Results will be graded at the end of the race as posted on the official site for that series e.g. Nascar.com, f1.com, indyracingleague.com etc. If there was an error on the site in the posting of the results, then the results will be regraded. If changes are subsequently made due to appeals or decisions of the governing body unrelated to the original finishing order (i.e. penalties for rules infractions, dangerous driving, etc.) the original results will still be deemed as the official results for grading purposes. Appeals and administrative penalties are not applicable for betting purposes.

A driver must start for action. If the driver withdraws prior to the start of the race then bets on said driver will be refunded. If he withdraws after the start or is replaced by another driver all bets on that driver will stand. In the case of a replacement driver the original driver will be deemed as the driver of that car for the entire race.

If a race or qualifier is postponed for any reason, all wagers will remain valid for 4 Days (96 Hours). If the postponement lasts more than 4 Days, all wagers will be canceled and the monies refunded.
