. . . all caused by people in front suddenly stopping and ramming into her.

Unless this is poorly written (maybe someone in back rammed into her when she had to stop suddenly?) then I can't conceive how these accidents wouldn't all be her fault. She wasn't rammed if she hit someone who stopped in front of her, she did the ramming. If you're following to close and you hit someone, then it is your fault. That's the way it works in the US. Is it different in the UK? Unless it can be shown that the party in front did some strange maneuver to suddenly insert themselves into the lane in front of the party who hit them, and I imagine that is difficult to prove. It is here--everyone has a different version of the story to report IF you can get any witnesses to stop and make the report.
