168. When the starting judge so orders, each driver must direct his or her horse towards the starting gate placed approximately a quarter of a mile before the starting line.
The starting judge causes the starting gate to move towards the starting line, gradually increasing its speed until the required speed is reached.
When the horses reach the starting line or the safety line, as the case may be, the starting judge gives the official signal for the start of the race.
