Which action can the Board of Stewards take against a licensee for violating the Rules of Racing?

The Board of Stewards has the authority to impose varying levels of penalties for violations of the Rules of Racing, which can include fines, suspensions, or referring a licensee for revocation of their license. This range of disciplinary actions is designed to ensure compliance and maintain the integrity of racing.

Fines serve as a monetary penalty for violations, suspensions temporarily restrict a licensee's ability to participate in racing activities, and referral for revocation indicates a serious breach that could result in losing one’s license altogether. This layered approach allows the Board to respond appropriately to the severity of the violation and uphold the standards of the racing industry.

In contrast, the other options are limited or insufficient responses to the range of potential violations that can occur within the racing context. Issuing only a warning does not adequately address serious infractions and may fail to deter future violations. Blocking future racing entries similarly does not include the same level of consequences as fines or suspensions, and requiring additional training seminars, while potentially helpful, does not directly penalize the violation itself. The ability to fine, suspend, or initiate revocation proceedings is crucial for effective regulation and enforcement in horse racing.
