Be proactive!:idea:
Get with an attorney, get a copy of the police report. I hope you got names and numbers of the witnesses. Take photos of the "crime scene", especially the tire marks.
The best defense is a good offense.
The Boy Scouts are right, BE PREPARED.
A good attorney can advise you on how to position yourself. Get checked out NOW by a physician, unless you are a doctor. Two weeks from now when your ankle is still bothering you, won't be the time to have it looked at.
just my nickle Hope you feel better after the weekend.
