My question involves a traffic accident in the State of: California
I was driving in right hand lane and the other car was driving in the left lane of a two lane street, the traffic in her lane had stopped and the traffic in my lane was moving at at least 25mph there was a gap between my car and the car in front me and with no signal she tried to get infront of me into my lane I hit my brakes but still end up barely hitting the back of her car leaving a hardly noticeable mark right above her right rear tail pipe. She filed a claim with my insurance company and I don't know what she told them but there saying it's 100% my fault which I don't think it is being that she took my right-of-way and proceeded with an illegal and unsafe lane change into my lane. We didn't call the police so there is no report. Am I right or wrong? If I am right how do I prove it?
