School Bus Vandalock No Start Possibility

I can talk from experience that I had a few service calls that involved the vandalock system. When engaged the bus will not start which is the main reason they were installed.

Retired School Bus Tour

This is a retired school bus tour showing some features this bus came with from the factory. We have sold all nine of our retired buses to the same company which is unusual.
