On Feb 15, 2013. I was going down a busy 2 lane road and the cars infront of me slammed their brakes and I did too but there was a car behind me that didn't stop and it me on my left rear side and my car went to the opposing lane and went head on with it, i just came out with sprained wrist but my car got totalled and the car from the opposing lane too. And the car that hit from the rear, ran away from the scene. A month or so later the insurance company lets me go because I'm not at fault and on the last insurance statement it said that their claims were denied. But today, I received a call from my insurance company and they said that the car coming from the opposing lane has sued me. How can they sue me? I'm just as much as a victim as they are.
