I was in an accident on May 15, 2010 in Pittsburgh, PA. I was in the turning lane and had a green light as I was going through the light to make a left the arrow turned yellow than to a green circle. A car coming towards me smashed into my right front passanger side. I was more than half way through the light but the cop, who didnt do a sobriety test or ask me for anything but my licences, said that no matter what if you make a left turn its your fault. They also claim to have a witness but I was watching the cop the whole time he didnt talk to anyone besides the people in the accident. I then got a ticket for failure to yeild right and a point on my licences. What should i do?
