Except by special permission of the official in charge, every jockey must upon pulling up unsaddle his own horse, and no attendant shall touch the horse, except by his bridle. Upon the returning of a jockey to the winner's circle to dismount after a race has been run, no one may touch the equipment of the jockey until he has been weighed in, except upon the approval of the official in charge.
