No whip shall be carried on any two-year-old until he has had two workouts under the supervision of the stewards. Thereafter, the decision as to when a horse is running true enough to permit the use of a whip shall be at the discretion of the stewards. No whip shall be carried on any horse in any race when making a first start unless its use has been approved by the stewards.
