A dual position step assembly that can be mounted into a standard square towing receiver that is previously installed on a pickup truck or similar vehicle is described. The step assembly is mounted to the rear of the vehicle. The step can be pivoted to two positions, either vertical or horizontal. When placed in the vertical position the step assembly automatically seats into a downward self locking position. The weight of the step assembly provides the force necessary to set the step assembly into the self locking position.
