Abstract: A removable step, carried by a highway transport vehicle laterally adjacent the threshold of a side door defined in a cargo container body, aids worker access through the door. The step provides fastening legs releasably maintained in spaced fastening brackets carried by the vehicle frame. The fastening legs are inserted in the upper portions of the fastening brackets in a use mode and in the lower portions of the fastening brackets, with the step extending inwardly, in a storage mode. A releasable fastening pin extends between each fastening leg and associated fastening bracket for positional maintenance of the step in either fastening or storage mode. The step surface is of a non-skid expanded metal type.
