in many states unless someone is hurt or property (other than the vehicles involved) damaged, there is no police report.
I am not familiar with those states.
Police report? What if you wreck your scoot on a quiet road with no one else involved and you aren't injured and are able to get the bike home. Should you still call the police? and if not, is your insurance still liable to fix the damage?
You did not read my full statement then so I'll quote myself -
If the damage is high enough that you would make a claim it's most likely going to be looked upon with some suspicion if there is no police report to go with it.
As for your second quesion, I don't know. I would be willing to bet that you'll have a tougher time getting them to pay up without the police report.
