Section 303.13 - Trainer responsibility rule

(a) The trainer is responsible for the condition of the horse entered in an official workout or race and is charged with the responsibility to guard and protect the horse at all times regardless of the trainer's location. The trainer shall be responsible for the presence of any prohibited drug, medication, agent or other substance, including permitted medications in excess of the maximum allowable level, in these horses. A positive test for a prohibited drug, medication or substance, including permitted medication in excess of the maximum allowable level, as reported by a Commission-approved laboratory, is prima facie evidence of a violation of this rule. In the absence of substantial evidence to the contrary, the trainer shall be responsible.

(b) A trainer shall prevent the administration, attempted administration or passive contamination by others, including the trainers' employees and assistants who have care, custody and control of the horse from any drug, medication, or other prohibited substance that may cause a violation of these rules.

(c) A trainer shall immediately report to the Stewards and the Commission Veterinarian if the trainer knows, or has cause to believe, that a horse in the trainer's care, custody or control has received any prohibited drugs or medications.
