<prompt> Human: I was involved in a minor car accident. While stopped at a cross walk, the driver behind me slammed into to the rear of my car, resulting in some damage to my rear bumper.We exchanged info. I had a cop come by to take a look. And the driver filed a claim with their insurance company. I responded to a call from their insurance company and gave them my account of what happened. The driver admitted fault to me, but Im not sure they said the same thing to their insurance company...My question: do I need to contact MY insurance company to let them know what happened? Is there a downside to doing that? Again, the damage is pretty minor.  <response>: Previously, I contacted my insurance to let them know I was in an accident and the cop had already declared the other driver at-fault. They took care of the work that had to be done with dealing with the other driver and their insurance.
