My question involves a traffic accident in the State of: California
I was waiting on veteran ave to turn left onto gayley ave and since it is a one lane street on all directions there was a car on the opposite direction waiting to turn right so it held back all the cars so there was no incoming traffic on veteran ave. I did not want to risk it so I waited until it turned yellow to turn. As I am about to complete my turn I see a car speeding towards me (on veteran) and hits the back of my car (which I was already on gayley). I stopped to exchange information. I reported a claim to his insurance and two weeks later they deny my claim saying it was my fault because the cars straight have the right of way, but when I turned there was no incoming traffic which made it safe for me to turn left. No police report since he agreed it was his fault and were willing to exchange information.
Can I argue that he ran a yellow light which caused the accident?
