Due to the words and phrases you used, I can tell you're in the UK. While most aspects of your country put you as one of the leaders of the free world, your traffic and insurance laws are straight out of any communist dictatorship.
Hell yes get a lawyer, or at least a traffic defender. Traffic defenders, if you have them where you live, are often just as effective as lawyers but not nearly as expensive. They're usually paralegals or ex-cops (or both), and they know the technical traffic laws and courtroom procedures as well as any lawyer.
However much trouble your daughter is in, she is entitled to plead her case in a court of law and she has the right to independent legal advice. Look for a traffic defender in your area.
