A stop motion device for use in preventing or arresting movement, more especially for a vehicle when reversing, comprises detection means movable between an inoperative or retracted position on the rear of a vehicle to a rearwardly extending activated or operative position. When the detection means is in its operated position, contact of the detection means 26 with, or breaking of an infra-red beam (50, figure 3A) of the detection means by, an obstacle effects an immediate automatic application of the vehicle brakes and also simultaneous movement of the detector means to its retracted position. Thus for a reasonable cautious reversing speed, the braking distance of the vehicle is accommodated before it strikes the obstacle. With detection means 26 only light initial contact of the detection means 26 with the obstacle occurs.
