Abstract
A vehicle 1 which is travelling along a lane 2a of a road in a direction A is fitted, by means of a support 1d, 1s with at least one optical or magnetic receiving device 5, 6 designed to detect and signal the presence and passing over B of a longitudinal boundary line 39 and/or the presence of the guard-rail 4 at a certain distance. The detection members 5, 6 are connected to a device for processing and amplifying pulses 7 and then to a control and command console 8 and a sound source 9 or other signalling device designed to warn the distracted or drowsy driver. <IMAGE>
