Paramedics took it. I don't know where it ended.
Not to be rude, but you need to understand that those people rush, take everything out of you, put you in an ambulance and 5 min later you're on the road. Is not that you have time to think about that kind of stuff.
They care about your life, not legal matters. And at that point, they do not know how bad your injuries are.
Ah. I infered that you got rid of the helmet. My mistake. In that case, tell the insurance you no longer have it due to being carted off on a frickin' strecher!
