    Smog Exemption

  • A STAR smog station is subject to additional oversight and review by the BAR, and they conduct more strenuous smog testing. There are two types of STAR smog stations: STAR Test Only Centers, which are licensed only to conduct smog tests; and STAR Test & Repair Centers, which are authorized to both conduct smog checks and to conduct smog check repairs. STAR stations can conduct both regular and STAR smog checks.

    STAR Certified Smog Station

  • Test-Only stations are licensed by the state only to perform tests on vehicles. They are prohibited from performing any repair services. Gross Polluters can also be certified at these stations. In addition, potentially high-polluting vehicles in the state’s smoggiest regions are directed to these stations for their initial Smog Check inspections, as specified on the Department of Motor Vehicles registration renewal form.

    Smog Check Test Only Station

  • 1. The Department of Motor Vehicles renewal notice will indicate whether a Smog Check is required to re- register your vehicle.

    2. Most areas of the state require vehicles to have a Smog Check performed every two years, when being sold, and when being initially registered in California. These areas are referred to as the state’s Basic and Enhanced Areas. However, Change of Ownership Areas only require a Smog Check when the vehicle is being sold or initially registered in California.

    Who's Required To Smog Check

  • Currently, smog inspections are required for all vehicles, except: diesel powered vehicles 1997 year model and older or with a Gross Vehicle Weight (GVWR) of more than 14,000 lbs, electric, natural gas powered vehicles over 14,000lbs, hybrids, motorcycles, trailers, and gasoline powered vehicles 1975 and older.


    Vehicles registered in areas subject to the biennial smog certification program are required to submit evidence of a smog certification every other renewal period. Owners of vehicles 6 or less model years old will pay an annual smog abatement fee for the first 6 registration years instead of being required to provide a biennial smog certification. The registration renewal notice mailed to you by the department will indicate if a smog certification is required. If a smog certification is required and you have not had a smog inspection, you may still pay your registration fees to avoid any late fees. However, you will not receive your new registration or year sticker until the smog information has been received by DMV.



    NOTE: Upon initial registration, nonresident;

    • Diesel powered vehicles 1998 model year and newer with a (GVWR) rating of no more than 14,000 lbs, and specially constructed vehicles 1976 and newer require smog certification. The 6 or less model years old rule does not apply to these vehicles.

    • Hybrid Vehicles require a smog certification


    When you transfer a vehicle that is 4 or less model years old a smog certification is not required. (Determine the oldest-qualifying year model by subtracting three from the current year.) The 4 or less model years old rule does not apply to diesel powered vehicles. A smog transfer fee will be collected from the new owner . When a vehicle is more than four model years old, a seller must provide evidence of a current smog certification except when one of the following occurs:

    • The transfer occurs between a spouse, domestic partner, sibling, child, parent, grandparent, or grandchild.

    • A biennial smog certification was submitted to DMV within 90 days prior to the vehicle transfer date (a vehicle inspection report may be required for proof of certification).


    Smog certifications are good for 90 days from the date of issuance.
