Write the first description in plain facts

After reaching a safe location, record what you personally observed before comparing notes with others. Separate a fact you saw from something another person told you.

  • Any plate characters and the state if visible
  • Vehicle color, body type, damage, decals or unusual features
  • Direction of travel and last location seen
  • Driver description only to the extent actually observed
  • Time the vehicle left and when the agency was contacted

Preserve independent leads

Photograph your vehicle or damaged property, debris and paint transfer without disturbing the scene. List cameras that face the roadway, but label each one as a possible lead until its owner confirms that footage exists.

  • Damage transfer, debris and marks from several distances
  • Witness name, contact details and description in that person's words
  • Business, transit, residential or vehicle-camera location
  • Camera owner or contact method if voluntarily provided
  • Original photos, videos, voicemails and messages backed up

Track the report from first contact onward

Save the agency, time of contact and incident or report reference you receive. Use the official SJPD or CHP page that matches the investigating agency; do not guess the custodian from the fact that the other vehicle left.

Also review the DMV SR-1 criteria, which are separate from the collision-report request.

  • 911, dispatch or non-emergency contact time as appropriate
  • Agency name and incident, call or report reference
  • Officer or unit information actually provided
  • Report-request status notes and DMV record kept separately

Ask your insurer about the process that applies

Notify your insurer and describe the event accurately. Do not assume that a particular coverage applies or that the unknown driver has no insurance; ask for the insurer's written explanation and save each request.

  • Claim number and representative contact
  • Copy of the agency incident information supplied
  • List of requested photographs, estimates or statements
  • Written coverage or process explanation from the insurer
  • Tow, repair, rental, medical and other expense records
