I also am not sure of who's guilt it is. I'll run it by my dad (who at least went to law school), but the law is probably different there.

I'm not sure if it's the law here, but I was at least taught that you should never make a U-turn in the middle of a road. Of course, I wouldn't need to be told that because to me, it just seems like a stupid thing to do.

By the way, I hope you weren't injured too much.
