If involved in an accident in California without a police reportmy fault with damage to other vehicle does the insurance company file a report with dmv?

I ythinnk it depends which state you reside in. In most states, unless someone is injured or their is property damage you do not need to have a police report. Actually, many police will not write a report at all unless there is actual damage. If there was no report and no injury the DMV will not know in MHO>
