Not sure where in the US you are, but while the property damage portion you might be a bit SOL on, your PIP and Uninsured Motorist coverage (if you have UIM) should at least cover the medical portion to an extent, and possibly some of the property. Also, was this a commercial vehicle? If so, have your insurance claim rep and attny look into tracking down the company and the police report if you don’t have it already, could go after the company for the portion of the property damage they’re responsible for. Otherwise it’s still possible to pursue them personally for damages (depending on how auto liability laws work in your state, if it’s comparative negligence, pure liability or 50/50), even if not much comes out of it, insurance companies usually have some kind of collection agencies they work with in dealing with uninsured motorists.

The most important is that you are alive.
