driving an ambulance does not exempt you from the rules of the road, and fleeing a state trooper who is attempting to pull you over is generally frowned upon by all involved. especially a high speed chance, than you are committing numerous violations including failure to stop, and most ambulances I know don't handle well to begin with, let alone with you are being chased by the cops with a patient in the back.
When I was dispatching I had an officer in another county call me and ask if a unit had a patient on board, and when I said no he asked if I would ask them to pull off at the next intersection and stop in a truck stop parking lot so that he could chew them out without making it look like he was pulling over an ambulance. I thought that was nice and decent of him Hard to tell them that and not laugh on the radio.
As he started to chew them out there was a bad wreck in the intersection and they ended up transporting 2 patients out of the 6 involved, so I don't think the officer ever finished chewing him out
