He laid the bike down and did some damage to himself and to the bike. It was the other driver's fault, but he did not have a motorcycle license or permit (which is why he didn't ask - I'd have said no!). The other driver's insurance probably will not pay the claim unless I file charges against my friend for unauthorized use of a vehicle. I realy hate being in this situation. What are the possible legal consequences for my friend if I file this against him?
