Yesterday my girlfriend was pulling out of a parking spot with a large truck parked on her right. She was backing out slowly because she couldn't see very well, normally in situations like this I would get out to see but we were leaving the hospital where i had a medical procedure and couldn't. When pulling out another car sped through past her, the tail of her car was poking past the parked truck at that time. She hit the side of the other car, and the car was going fast enough that it tore her bumper off. Who would be found to be at fault?
