You have been involved in a minor traffic collision with a parked vehicle and you can't find the owner. You must:

  1. Leave a note on the vehicle.
  2. Report the collision without delay to the city police or, in unincorporated areas, to the California Highway Patrol.
  3. Both of the above. ✓

Answer: C. Both of the above.

You must do both: leave a note with your name, phone number, and address on the parked vehicle, and report the collision to law enforcement.

Why this is the answer

The handbook says that when your vehicle hits or rolls into a parked car and you cannot find the owner, you should leave a note with your name, phone number, and address, attach it securely, and report the collision to law enforcement. It does not say to pick only one of those steps. The bank answer combines them, so leaving the note and making the report are both required in this situation.

Why the other answers are wrong

Remember it

If the owner is missing, handle both ends: a secure note for them and a report to law enforcement.
