Competitors must take the reins and whip, if carried, in one hand. The free hand should be lowered to the rider's side and the rider should nod their head. Gentlemen may salute in the same manner, or, if they wish, they may remove and lower their hat with their free hand before nodding.
If the salute is at the beginning of the test I look at which way we have to turn at C if left then I will salute with my right hand as if carrying a stick it is most likely to be in the inside hand. If turning right then I'l salute with my left hand.
If at the end of the test it will be with the hand that is not holding the whip - or if not carrying a whip then either hand
