Abstract (en)
A vehicle (1) is equipped with two rearward-protruding arms (3, 4) preferably spring-loaded which on reversing into an obstacle are telescopically pressed in and so actuate elements which cause the vehicle to stop or reduce its speed. The arms (3, 4) are provided with at least two devices (5, 8) for emitting and receiving radiation which passes between the arms (3, 4) the said devices (5, 8) controlling the drive unit of the vehicle in such a manner that an interruption in the beam of the second device (7, 8) causes the vehicle to stop unless two sensing elements (9, 10) mounted on each arm (3, 4) between the first device (5, 6) and the second device (7, 8) have both indicated that a pallet-like object has been introduced between the arms (3, 4), causing the vehicle to stop if a person, for example, is standing in its path but allowing it to continue if a pallet, for example, is there.
