A U-turn signaling attachment useful with the turn signal stalk of a motor vehicle includes a frame conformed for engagement to the stalk and a lever pivoted on one end of the frame. A cam edge is fixed to the lever to oppose one end of a push rod which, at its other end, oppposes a double lobed surface attached to the steering column. The cam edge, at its center position, is chamfered transversely to clear the push rod during fore and aft motion.
