What happens if you have an accident in your vehicle with no other cars involved and you leave the vehicle at the scene?

Doing so is automobile abandonment. If left for several days, the local police will check for ownership via the license plates or VIN of the vehicle. Attempts will be made to contact the owner - If the owner cannot be reached, then the vehicle will be towed to an impounds lot. Parking is not free at the impound lots - sometimes as much as $8 per day in some regions. The owner will be required to pay the parking fees AND the towing charges before the car can be removed from the impound lot.
