When a dangerous goods transport vehicle moves at a high speed, the censor at the rear of it can perceive the distance from the vehicle behind. If the distance is less than the “safety distance”, the words, “Keep Vehicle Distance”, will be projected on the ground at the back of the transport vehicle.
