I am a driver for a municipal fire dept. in NC. I was responding to a vehicle fire w/ subjects trapped on I-40. Traffic in all three lanes were stopped by a police officer, so when I entered I-40 I commited the truck to the left hand shoulder of the roadway. While approaching the vehicle fire, a Chief from a neighboring volunteer dept. passed on the right hand shoulder w/ lights and sirens. A minivan pulled to the left and encroached my clearance to pass. I tried to avoid the accident by pulling the truck as close to the concrete barrier that divided eastbound and westbound lanes. As I had no room to stop the 30ton truck, right side steps into the cab clipped the minivan. Minimal damage was caused to the truck. As we were approx. 100 yards away from the fire, the decision was made to proceed on. I informed the police officer, and the captain of the next incoming unit. They failed to check on the driver of the other vehicle. I wasn't written a ticket by the police, but the heads of the FD I work for called me in and told me I could be charged with felony hit and run. Given the circustances involved, is this true?
