NASCAR has banned its members from wagering on its races as more US states authorize legal wagering within their borders.

On Monday, the National Association for Stock Car Auto Racing (NASCAR) announced its new Sports Betting Policy, which bans team owners, drivers, crew members and officials from gambling on NASCAR events. The policy also prohibits sharing inside information with third parties that could be used for betting purposes.

NASCAR members are also required to fink on anyone they suspect of involvement in any of the transgressions listed above “without undue delay.” Failure to comply with the new policy could result in fines ranging from $150k-$250k, along with the possible indefinite suspension or even termination of one’s membership.

NASCAR members who violate the new policy will receive a written communication detailing the steps they need to take to get back into the body’s good books. Only after completing these requirements will a member be eligible to be even considered for reinstatement.
