I did that shit in a Fire Engine 6 months ago. We went on a call that dictated Code 3 to get there. Once we cleared I turned the master warning lights off, and we headed back to the fire station. Few blocks later we got toned out on a fire alarm. I pulled up to a red light, looked both ways, two cars stopped and we went through it. The Captain said "do you have the lights on?" Me "nope". Captain "well you just ran that red light". Me "P.D. ain't gonna pull us over, and those people are probably dumb anyway."
