Non-owner car insurance is an operator's policy. Vehicle Code section 16452 insures the named person for liability that comes from using a motor vehicle that person does not own, and a vehicle that person buys later, for no more than 10 days after the purchase.
DMV SR-104 uses that split on an SR-22: owner's certificate, operator's certificate, or broad coverage. The operator's policy keeps the same territory and the same limits as an owner's policy under section 16451, which follows the registered vehicle. The operator's policy follows the driver. It is not collision or comprehensive on someone else's car, and those coverages alone do not meet financial responsibility. For a policy issued or renewed on or after January 1, 2025, section 16056 sets the floor at $30,000, $60,000, and $15,000.
