(a) No person may be licensed as a trainer, owner, trainer-driver, or in any other capacity in which such person acts as the employer of any other licensee at any authorized race meeting, unless his liability for worker's compensation has been secured in accordance with the Labor Code of the State of California and until evidence of such security for liability is provided the Board. Should any such required security for liability for worker's compensation be cancelled or terminated, any license held by such person shall be automatically suspended and shall be grounds for revocation of the license. The trainer of a public stable shall provide evidence that the policy of insurance securing his liability for worker's compensation has been endorsed or amended to include, as an additional insured, each person for whom he trains horses to the extent that such person is exposed to liability as the employer of a jockey, unless such person has procured coverage for such exposure and has furnished evidence of such coverage to the Board.

(b) No licensee, for the purpose of avoiding the requirements for workmen's compensation insurance as set forth in this article, shall place any horse in the care of or attendance of any other person.
