My girlfriend was driving some friend back home from the bars last night. She was being the Designated driver, she was at a four-way intersection waiting at a red light when a drunk driver slammed into her car and completely totaled it. He drove off but a worker at a gas station next to her saw the whole thing and called the police with the details of the car. They were caught parked on a street a couple miles away. It was pretty obvious considering my girlfriends car had been totaled. What do we do now?
She had just gotten her car on a lease. The car is unfixable and she doesn't know if she's going to have to lease or buy a new car. Does the guy who hit her have to pay for everything? This has never happened to us before so we don't know what to do.
