Abstract
A door-activated retractable step for a truck includes at least one step cavity disposed within a side wall structure of the truck in proximity to a door thereof. An extendable cover for the step cavity housing, when closed, creates an aerodynamic continuation of the side wall structure containing the step cavity. The cover is pivoted about a horizontal hinge in response to the truck door being opened to form a continuation of the tread surface, creating a wide step.
