On school buses specifically, which of the following should be checked?

Stop Arm: If equipped, check the stop arm to see that it is mounted securely to the frame of the vehicle. Also, check for loose fittings and damage.
Passenger Entry/Lift:
- Check that the entry door is not damaged, operates smoothly and closes securely from the inside.
- Check that entry door glass is clean, not cracked or missing.
- Hand rails are secure and the step light is working, if equipped.
- The entry steps must be clear of debris/snow-ice and the treads cannot be loose or worn excessively.
- If equipped with a handicap lift, look for leaking, damaged or missing parts and explain how lift should be checked for correct operation. Lift must be fully retracted and latched securely.
Items such as kingpin and pintle hook do not apply to school buses.
