So, I was involved in a minor accident yesterday afternoon. I was rear ended at a slow speed. I was stopped behind a few cars and we were all waiting for a bus to cross train tracks. the driver behind me hit me, was probably slowing down from 30 mph. the good news is her bumper went under my back bumper and made a few scrapes there but no bumps or major damage. Her car did not appear to be damaged either. We exchanged info and left and did not call the police. I've never been in an accident so I wasn't sure if I should call them or not with there being no obvious damage. This morning when I woke up my back and neck hurt. Not bad, but enough to notice it. I don't think I need medical treatment and it will probably go away in a couple days. I am guessing it's just some soreness from the impact. I was wearing my seat belt as always. Not sure what to do here, should I report this to the police? Can I , even though it was yesteday?
