There's a story in OK about a cop pulling an ambulance over for failing to yield, although they were both on a call. I can link the story if you'd like, but not trying to get off topic.
Question is.....if they both have the right of way....who yields to who? and can a police officer really write a ticket to an on duty, middle of a transport, ambulance?
