Typically the person who hit you pays. If they don't have insurance, your no fault insurance will pay for it.
Car A pays- He started it. That's not always true. Was sitting at red light, was hit by other car that had been hit by other car. Insurance Co. said neither car was at fault, my insurance fixed my car. No fault ins.
The other person pays.
