ABSTRACT:
A bus vehicle includes an entry way having a lower step, a middle step and a third step which is the floor of the vehicle. The bottom step is vertically movable to three positions, a ground engaging position, a position in the plane of the bottom of the vehicle and a position in the plane of the vehicle floor. A step extension portion is pivotally connected to the movable step and pivots out of the way when the step is in its two lowered positions and pivots to a horizontal position when the step is in its raised floor position thereby providing a continuous floor over the entry way. A closure plate closes the bottom of the entry way and is movable downwardly by the movable step when moving to its ground engaging position.
