The lift shall be designed to meet the Federal Department of Transportation Regulations 49 CFR 38.
The lift shall include a hinged platform to bridge the coach floor to the lift platform. Bridge shall be

turned "On" or the lift door is open, for maximum safety. These features shall be wired to the lift
master switch to allow activation only when the transmission is in neutral. The coach directional
(Hazard) lights will also flash on/off. After the lift operation is completed, the lift shall be properly
stored and secured, with the access door closed and the lift master switch at the dash in the "OFF"
position in order to move the coach.
The lift door shall have a window in line with the other passenger windows and shall not detract from
the appearance of the coach. The door latch mechanism shall be located in the lower section of the door
