Do I still have a case if I received a traffic citation stating I cause of the accident?The situation depends if the accident was not completely your fault. You can still recover damages from the other driver for the portion of the accident that was his or her fault.
Do I have to let my insurer know about the accident if the accident was not my fault?Yes, you need to inform your insurance company of the accident even if you weren't at fault.
What if I don’t report the accident to my insurance company?If you do not report the accident, the insurance company may deny payment of any claims you file subsequently. Your insurance company must notify you within 30 days of receiving proper notice of the claim whether it will pay or deny your claim, or inform you that it is still in the investigation stage.
