Most insurance policies require their policyholders to promptly report every accident involving an automobile.  Your own insurance company needs to gather information regarding your accident for its records regardless of fault.  Failing to provide necessary information to your insurance company in a timely manner may result in your insurance not covering you for the accident.  This may occur and it would not be considered a bad faith maneuver by your insurance. 

Your auto policy will dictate the time frames in reporting an accident, and it is a good idea to review your policy for this information.  It is recommended that if you or your passengers were injured in an accident, or if you have any issues regarding your coverages, you should immediately contact an attorney for legal consult.
