Abstract
A retractable stairway assembly for entering and exiting a vehicle with a cab has a stairway with steps. The stairway assembly is movable between a retracted position, in which the stairway is beneath the cab, and an extended position, in which the stairway is exposed to allow entering and exiting of the vehicle. The stairway assembly also has a panel that substantially hides the stairway when in the retracted position. An actuator moves the stairway assembly between the retracted and extended positions in response to closing and opening the door.
