R 431.4225 Gate restrictions.

Rule 4225. (1) A person, other than the official starter, his or her assistant, and a patrol judge, shall not be allowed to ride in the starting gate unless permission has been granted by the stewards. (2) Use of a mechanical loudspeaker for any purpose other than to give instructions to drivers is prohibited. The volume shall not be higher than is necessary to carry the voice of the official starter to the drivers. (3) If there are 2 tiers of horses, the withdrawing of a horse that has drawn or earned a position in the front tier shall not affect the position of the horses that have drawn or earned positions in the second tier. When a horse is drawn from any tier, horses on the outside shall move in to fill up the vacancy. When a horse has drawn a post position in the second tier, the driver of the horse may elect to score out behind any horse in the first tier if he or she does not thereby interfere with another trailing horse or deprive another trailing horse of a drawn position.
