    Are you moving to California or buying a vehicle from another state? Before you hit the DMV, here are the top 10 things you must know to avoid fines, delays, and stress when registering your out-of-state vehicle in the Golden State.

    1. You Must Register Within 20 Days

    California law requires new residents to register their out-of-state vehicles within 20 days of establishing residency to avoid late penalties.

    2. Smog Certification Is Mandatory

    Most vehicles must pass a California smog check, even if they passed in another state. Vehicles under 4 years old may be exempt.

    3. Bring Your Out-of-State Title

    You’ll need the original out-of-state title to transfer ownership and register the vehicle—no copies allowed.

    4. VIN Verification Is Required

    The Vehicle Identification Number (VIN) must be physically verified by a DMV employee, licensed verifier, or law enforcement officer in California.

    5. Use the Correct Forms

    Don’t show up empty-handed. Bring a completed Application for Title or Registration (Form REG 343) to save time.

    6. Pay All Required Fees

    You’ll be charged registration, title, use tax, and possibly smog abatement fees—based on the vehicle’s value and location.

    7. Insurance Must Be California-Based

    You must carry California liability insurance before registering your vehicle.

    8. Out-of-State Vehicles May Need Modifications

    Some vehicles, especially older or non-California-emission models, may require modifications to meet California emissions standards.

    9. Commercial Vehicles Have Special Rules

    Registering a truck, van, or business vehicle? You may need a weight certificate and additional fees.
