What to Do If You Unknowingly Scratched a Car and Left Without Knowing, and the Other Party Reported to the Police?

[LaPreston]

If the traffic police department determines that you indeed did not know you scratched someone else's car and left unknowingly, then it cannot be considered a hit-and-run. Although it is not a hit-and-run, the fact remains that you scratched someone else's car, so you must either use insurance or pay out of pocket to cover the repair costs for the other party.
