ABSTRACT:
An electronic self-canceling turn signal device for use with a motor vehicle, and most advantageously a semi-tractor/trailer, having turn indicators or indicator lights providing numerous features. The electronic self-canceling turn signal device provides for the driver of the vehicle to make a wide or sweeping turn maneuver in an indicated direction by initially turning the vehicle in a direction opposite or counter to the indicated turn direction and then executing the indicated turn without canceling the indicated turn signal. The electronic self-canceling turn signal device further provides a time delay between the point in time a tractor completes an indicated turn and the time that the electronic self-canceling device cancels the indicated turn signal so that trailers pulled by the tractor will complete the indicated turn before the turn signal is canceled.
