Re: the vandallock
That handle is the manual release for letting the door open. The "Vandallock" is actually an electronic lock-out system that prevents the bus from being started unless certain things are done first. Specfically one needs to unlock the rear and side emergency doors (they have to be unlocked while hauling kids around in case of accident, the vandallock prevents the bus from starting if those are not unlocked first). It's easy enough to bypass, and can be used for additional security if you're worried about the bus getting stolen.
The system was designed so that when the bus is parked, they can lock it up to prevent people getting inside of it and vandalizing things. Most School buses are not secure and cannot be locked.
You just might be a Redneck if...
...your motor home used to be a school bus!
...Your living room has a steering wheel!
...Your home has brake lights
