I was in an accident like this back in college. The g/f and I were heading south on a road coming back from renting a movie, she was driving. There was an old man, his wife, and their special needs daughter in the northbound turn lane waiting to make a left across our lanes. We had a green light and they had a yield on green. We were doing about 45mph (the speed limit) and it had just started to rain. As we got to the intersection, the old guy pulled right out in front of us.
It happened so fast there wasn't time to do anything. Luckily the g/f had #$%*ed at me literally 1 minute before about putting my seat belt so we both had them on (i probably would have died otherwise), but the car was old (87 ford tempo i think) so it didn't have air bags. I remember the g/f screaming right before impact, chaos, and then us rolling backwards down the side street the old guy was trying to turn on to. I had the where-with-all the pull the e brake so we came to a stop. Their car shot off to the left and went through a fence and almost hit a house 50 feet away.
Sadly we hit the front passenger door where the lady was sitting and she died on impact. The old man was pretty banged up and had some lacerations on his legs. I had serious whip lash and a nasty seat belt burn across my chest and lap. The seat belt chewed through the shirt i was wearing, I still have it somewhere. My g/f must have hit the steering column because she had a pretty bruised sternum. The worst part of it all was after i got out of our car I looked over at the other car and saw the daughter in the back screaming/ crying shaking her mom who's head was just rolling around as she did it.
Needless to say there was an investigation. We weren't found at fault for anything and now they have a turn arrow only for that left.
