ABSTRACT:
A stair construction for a vehicle is attached to the vehicle at a position below a vehicle door and supports the weight of users entering and exiting the vehicle. In the event of forces that tend to bend or push the stairs upward into interference with the door, the stairs will fracture and break or generally predictably deform so that they do not interfere with the door.
