That is really messed up.
I borrowed my father's F350 SD Dualie in the spring to pick up a new dishwasher. On the way home, the wife and I got hit from behind by a teenage girl with three other kids in the car. She totaled her car and stuffed my three ball hitch through the block. Wife looked at me and said "what was that?" I think we just got hit.
The sum of the damage to the truck was a lima bean sized dent on the bottom of the tailgate where her hood buckled into it. If it had been my truck I would not have even filed a claim but there was no way I was giving a borrowed truck back with damage, no matter how small. Her insurance company insisted on replacing the rear bumper, reciever, and paiting the gate. I still have a perfectly good reciever and chrome bumper in my garage.
Anyway, short story long, the officer gave both of use a form with the others info before we left the scene.
Best of luck with your issue!!!
