About a week ago, I was driving on a busy Boulevard in Los Angeles on my way for a afternoon lunch. I was on a residential street heading towards the Boulevard. I come to a stop (posted stop sign) at the corner where you can only make a left or a right turn onto the Boulevard. I had a clear view of traffic in both directions. When I saw it was safe and had a chance to turn I made a LEFT turn. In the process of making a left turn, a female on the inner lane of the Boulevard rear ends me. She struck the back right side (passenger rear end) of my car forcing my car to do a 180 spin. Luckily where my car and I landed, I didn't hit any parked cars. There was another vehicle driving slightly behind her on the outer lane. Another vehicle was behind her in the same lane. These other vehicles were not close to hitting me and still were able to slow down or stop safely to avoid the accident. Those vehicles witness the accident but when safe they drove off. She never attempted to stop so she didn't skid nor did her air bags go off. She clear stated to myself and the officer that "she didn't see me at all" "she didn't know where I came from" "I came out of know where". I don't know if she was on her cell phone, changing the radio station, or just day dreaming to be aware of traffic. Officers were called onto the seen right away. We both have insurance. I only have liabilty. I don't believe I was at fault for the accident. I had enough space and time to make a left turn onto on coming traffic. I am not sure if I'm liable for the collision because I made a left turn? Or is she liable for rear ending me? WHO IS AT FAULT AND LIABLE FOR THE DAMAGES?
