on their insurance company and this is why. First off...I haven't heard all the specifics regarding your accident. But, looking at the pixtures alone, here's what I see.
1.
You have the right of way. You are on the main road and he is, what appears to be, making a left turn in front of you. You probably have the option of going straight or turning right. BUT, he must yield right of way to you. Is there a stop sign for him? I don't see one. Again, this is what I see from the pix.
2. I've seen hundreds of accidents. If you were going too fast, there would most likely be more damage than that. I'd say you were doing 15mph...MAYBE 20 tops...but doubt that. And...if you were going too fast, not only would there be more damage, but the other car would have probably been moved over to his right more. No...you weren't speeding.
3. He came to a stop and then backed up???

You don't pull out in front of someone to go "OH SH!T" and throw it in reverse to back up. That's just not how it works and isn't a normal response. The normal response is to floor it or slam on the brakes. You don't stop and reverse.... AND...if you do, you're still at fault.
4. He already failed to yield ROW, but yeah...it looks like he cut the turn. Cutting the turn would not make it his fault or your fault in the acc....unless he has no stop sign and was making a left in front of you as you were making a right. Then, by him cutting the corner, would be an improper left turn (cut corner on left), and you could even go failing to maintain same lane (although I don't see any turn marks there).
5. It's tough to tell from those pictures, but you have to show a point of impact on your car and then show a direction of the scratches. That will usually help to give a reference point.
If any of this is right, take those pictures to his insurance company and don't settle on ANYTHING for the sake of settling. If you are 100% in the right, fight'em. I've had to do it before w/ other lying drivers and I've stuck it out. They got my first recorded statement and went back to their client. They called me back saying they got different stories. I told them, "Of couse you would. Because she doesn't want to take responsibility. I was expecting that." They asked for another recorded statment. I told them they could kiss it...becuase they already recorded a statement and if they "forgot" what I said, they could "roll back the tapes." No, I'm not stupid. They were trying to get me to foul up something and then use that against me. Please....they tried numerous times over the next two weeks for me to give another statement and I stuck to my guns. Next thing I knew...full check for all damages. AND, this was after the officer put the lady COMPLETELY at fault. Increadible what people do these days. Just suck it up folks...if you screw up, take it....
