It happened at 12ish am. The owners (a married couple) of the vehicle are out of town and will return in 2 weeks. It's unoccupied and there were no witnesses either.
I got out of a home party (my friend's b-day), was heading back home and that's when it happened. Not major but I still hit their rear bumper and it was a small scrape.
Do I have to tell my insurance the truth about it? It's obvious why. Yet I still thought I could make it home with no problems. Even with dizziness I saw myself with good coordinations so I trusted myself.
