I was driving and the lady in front of me slammed on her breaks which caused me to rear-end her. We exchanged information but we didn’t think it was serious so we didn’t call the police. She called me a few days later and said the damages to her vehicle were about $2,000 which was surprising. She told her insurance company that I rear-ended her but skipped the part about her slamming on her breaks. She also said she was going to call the police. I wonder in this circumstance, will the police still issue me a ticket even for an after-fact report? Should I contact my insurance company and file a claim?
