How Long Can You Drive on Temporary Plates From a California Dealer?

What the law says: Vehicle Code 4456

Section 4456, operative since January 1, 2019, governs what a dealer or lessor-retailer does when it sells a vehicle:

• Report the sale through the DMV's electronic reporting system and attach a copy of the report-of-sale form to the vehicle before delivery.
• If the vehicle does not display plates the DMV previously issued, attach the temporary license plates issued by the reporting system.
• Submit the registration or transfer application, with fees, within 30 days of sale for a used vehicle and 20 days for a new one. Penalties for missing that deadline are the dealer's to pay, not the buyer's.

Subdivision (c) sets the buyer's driving window: a vehicle displaying the report-of-sale form or temporary plates may be operated without permanent plates until the plates and registration card are received, or a 90-day period from the date of sale expires, whichever comes first. Subdivision (d) allows temporary plates beyond 90 days only if the owner can show an application for replacement plates under section 4457 and no more than 14 days have passed since permanent plates were issued; a violation of that is a correctable offense.

How the temporary plates must be displayed

Temporary plates are still license plates. Section 5201 says license plates, "including temporary license plates," must be securely fastened so they do not swing, mounted where clearly visible, and kept legible; when permanent plates arrive, the temporary ones must be replaced and destroyed. The DMV's dealer guidance adds that dealers attach two temporary plates to a car that needs two plates and has none, fasten them through all four corner perforations, and do not place them in the window. A car that already carries two permanent California plates, even expired ones, does not get temporary plates.

What it means in practice

The 90-day clock runs from the date of sale, not from when you notice the plates have not come. If day 60 arrives with nothing in the mail, start asking. The usual causes are paperwork the dealer has not finished, a title problem with a trade-in, or a DMV address that is out of date.

Insurance comes before the first drive, not after the plates. The law requires you to carry evidence of financial responsibility whenever you drive, and a lender will commonly want its interest listed on the policy before it releases the car. Temporary plates do not change either requirement. A private-party sale is different: no dealer reporting system, no temporary plates from the seller, and the transfer paperwork is the buyer's job.

What to do

1. Have the policy bound before you drive off the lot, and keep the proof in the car or on your phone.
2. Check that the temporary plates are attached front and rear and are legible.
3. Write down the sale date and set a reminder at 60 days.
4. If the plates have not arrived as the deadline approaches, contact the dealer first; the application is theirs to file.
5. When permanent plates arrive, mount them and destroy the temporary ones, as section 5201 requires.
