Abstract: The operator of a motor vehicle is provided with a glove or hand-worn member to which one end of a cord or other flexible member is attached with the other end being attached to the operating member of a switch or the trigger of an attention-producing device mounted to a fixed elevated portion of the vehicle located generally above the steering wheel. The cord or other flexible member is of such length that it is not taut when the operator's hand is in a normal driving position on the steering wheel but becomes taut before the operator's hand drops to his or her thigh. The alarm-producing device may be the horn with which the vehicle is normally equipped and the switch for the horn may be electrically interconnected to the storage battery with which the vehicle is normally equipped.
