ABSTRACT:
A pair of protruding forms, shapes or objects serving as steering aids or safety devices affixed asymmetrically to the left side of the hood or radiator of a car, as viewed from the driver's seat, methodically situated in such a position as to correlate each of the two forms, designated as road delineators, to its adjacent boundary line of the traffic lane in order that the driver can determine conveniently, correctly and continuously the exact distance of the car from either boundary of the roadway, enabling motorists, as they maintain their normal driving posture, to avoid accidents.
