Sorry to hear about your accident. Really Hate those people who don't accept responsibility for their actions. On top of it, you had a jerk of a trooper as well...
You may want to take you and your family to see a chiropractor on Monday. Sometimes, things get jostled up and need to get put back in place. You may start to feel sore in a few days too so now is a good time to put ice to minimize the inflamation
Take care and be well
