Abstract

According to the invention the device comprises an optical screen Sc, forming a zone of reduced transparency in the driver's visual field so as to attenuate all the luminous radiation coming from the part of the road (lane Cr) reserved for vehicles travelling in the opposite direction, and in which said zone of reduced transparency at least a little greater than the theoretical value alpha included, on the vehicle's windscreen Pb, between two ideal half lines s', m, respectively representing the margin of said part of the road (left-hand margin of the lane Cr) and the middle of the road itself, supposed to be straight and of infinite length, and intersecting in a point of convergence A, corresponding to the vanishing point of said half lines for the driver of the vehicle, said screen Sc possibly leaving the part of said theoretical angle close to said point A uncovered. <IMAGE>
