That happened to me although I didn’t hit a pedestrian, I hit another car. Actually, I backed into a car with my dad's van. I heard a loud "crunch" but as I unknowingly backed into the car, the spare tire in the back of the van fell on the metal floor. I honestly thought that was what made the sound. I drove off, driving down OP Road and got pulled over about 5 min later by OP's finest. They cited me for leaving the scene of an accident. Long story short, had a friend who worked for an attorney who got it reduced to a parking ticket albeit 110.00 parking ticket.
