New to California: Driver License & Vehicle Registration Guide (2026)
TL;DR: California gives new residents 10 days to apply for a California driver license once they accept residency (CVC §12505), and 20 days to register an out-of-state vehicle (CVC §6700). You skip the behind-the-wheel test if you transfer from a valid U.S. or qualifying foreign license, but you do take the vision exam and the California-specific written test. Smog certification is required for most non-resident vehicles. This guide walks the timeline, the documents (including REAL ID), the fees, and the 2026 changes for new Californians.
Table Of Contents
This guide is for anyone moving to California from another U.S. state or country. Out-of-state college students who maintain residency elsewhere have different rules — see the CSU/UC residency policies for those specifics.
The 10-day rule for your driver license
California Vehicle Code §12505 defines a resident as anyone who is "present in California for purposes other than a transitory or temporary purpose." Once you meet that definition, you have 10 days to either apply for a California driver license or stop driving with your out-of-state license.

Examples that establish residency:
- Renting an apartment or signing a lease in California
- Enrolling your child in a California public school
- Applying for in-state tuition at a UC or CSU campus
- Filing California state taxes as a resident
- Accepting employment in California (with limited exceptions for telework)
The 10-day clock is enforced lightly — there is no automatic ticket for day 11. But if you are stopped after 10 days with only an out-of-state license, you can be cited for driving without a valid California license.
Out-of-state license transfer
If you hold a valid U.S. driver license (any state), you skip the behind-the-wheel test in California. You still must:
- Pass a vision exam
- Pass the California-specific written knowledge test (46 questions, 38 correct to pass)
- Surrender your out-of-state license at the appointment (you cannot keep both)
- Pay the $45 application fee
Tip: California's written test covers California-specific rules (right-on-red, school zones, lane splitting). Use our California DMV practice tests to drill the question pool — even if you have driven 30 years elsewhere, the CA rules can surprise you.
Foreign license conversion
Drivers from certain countries can transfer without taking the road test, but most foreign licenses require both the written and the behind-the-wheel tests. California honors transfers without road tests from:
- Germany (specific federal states)
- Taiwan (under a 2015 reciprocity agreement)
- Specific provinces of Canada
- Some Mexican states under recent reciprocity
Drivers from countries without reciprocity follow the full California licensing process: apply for the permit, study, take the knowledge and road tests. International Driving Permits (IDPs) are valid only as supplemental documentation alongside your foreign license, and only for non-resident driving — they do not let you skip the California licensing process once you become a resident.
REAL ID for new residents
If you do not have a REAL-ID-compliant credential from your previous state, you need one to fly domestically or enter federal buildings. California issues REAL-ID-compliant licenses with one extra step: an additional proof-of-identity document. See our California REAL ID checklist for the complete document list.
You can request a REAL ID at the same appointment as your transfer — no extra fee, just additional paperwork.
The 20-day rule for vehicle registration
California Vehicle Code §6700 gives new residents 20 days to register an out-of-state vehicle. After that, late registration penalties begin to accrue.
To register, you will need:
- Form REG 343 (Application for Registration)
- The vehicle's current out-of-state title and registration
- A California smog certificate (most vehicles four years old or newer get an exemption from the initial smog requirement)
- VIN verification — by the CHP, an AAA office, or the DMV
- Proof of California insurance
- Use tax payment based on the vehicle's purchase price or fair market value, whichever is higher
Smog certification rules
California has the strictest emissions standards in the U.S. Most out-of-state vehicles need a smog inspection before registration. Exemptions:
- Vehicles four model-years old or newer
- Diesel vehicles 1997 and older, or with gross vehicle weight over 14,000 lbs
- Gasoline vehicles 1975 and older
- Electric vehicles (no exhaust)
- Motorcycles
Smog inspections cost $40–$80 at certified stations. If your vehicle fails, you may need repairs before California will register it.

Frequently asked questions
Do I have to surrender my out-of-state driver license when I get a California one?
Yes. The DMV cancels and returns your out-of-state license to the issuing state. You cannot legally hold two licenses at the same time in any U.S. state.
Can I keep my out-of-state vehicle license plates?
No. Once you register in California, you receive California plates and must surrender the out-of-state ones (or destroy them per the previous state's rules — practices vary).
How long do I have to drive in California on an out-of-state license before I must transfer?
10 days from the date you establish California residency. There is no grace period for visitors who become residents — the clock starts when residency begins.
Does California recognize International Driving Permits?
Yes, as a supplementary document for visitors. An IDP does not replace a California driver license once you become a resident — you must obtain a California license within 10 days.
What if I miss the 20-day vehicle registration deadline?
Penalties begin to accrue on day 21: $10 initial late fee, then escalating monthly. Register as soon as possible after arrival — the penalty system is not forgiving.
