Well, it doesn't matter where the car was hit really. The girl cut her off and hit the front of her car with the rear of hers. What is the other girl saying? Did she tell the police what she did? If so, it's open and shut.
Now, if the girl isn't copping to causing it, then it's going to be a fight, because the girl could say your girl hit her as well, which is bullsh*t. If they ask where the other girl was going, then with a road diagram, they can prove who was at fault.
But GET A DAMN ATTORNEY. My mom even asked if you had one. She said to get one NOW. A good lawyer won't ask for any money upfront. They will wait until the case is settled.
Good luck, hope your girl is doing better this morning.
