An impending crash detection system for tracked vehicles comprises a set of electromagnetic radiation emitter/sensors on each vehicle cooperating with retroreflectors on another vehicle or body. The emitter/sensor sets are angularly disposed so that they provide sequential signals indicative of decreasing separation, which are transmitted to a movement controller to reduce the selected drive speed at predetermined separations and, ultimately, to stop the movement. In the example shown in the drawings, the vehicles are handlers 1 and 2 linearly movable upon fixed rails (not shown) extending between end stops 3 and 4. The handlers are of similar construction and each consists of a carriage 5 supporting an extendable fork lift mechanism 6 movable upon a vertical post 7.
