Average operating speed The vehicle’s average speed is 20-35km/h, then the distance from the place where the sign is placed to the place where the signal is intended is 50-100m.
If the average operating speed of the vehicle is 35-50km/h, the distance from The distance from the place where the sign is placed to the place where it is intended to be reported is 100-150m.
