Abstract: A supplemental step assembly for a vehicle having a vehicle step includes a step which has a first end and an opposite second end. A first side member has a first step end which is connectable to the first end of the step, and an opposite first vehicle step end which is connectable to the vehicle step, the first step end being offset from the first vehicle step end. A second side member has a second step end which is connectable to the second end of the step, and an opposite second vehicle step end which is connectable to the vehicle step, the second step end being offset from the second vehicle step end. The supplemental step assembly can be connected to the step of the vehicle in either an upward projecting direction or a downward projection direction. The supplemental step assembly provides an additional step which reduces the vertical step height and facilitates entry of the vehicle.
