Where to take your smog test in Bakersfield

Bakersfield has two types of smog test stations: STAR stations (state-certified) and BAR 97 stations (Bureau of Automotive Repair certified). Both are authorized to test your vehicle and report results directly to the California Department of Motor Vehicles. You can find either type by searching the BAR station locator on the California Department of Consumer Affairs website — enter your ZIP code and it will show you certified stations near you with their hours and phone numbers.

STAR stations are typically faster and less expensive because they are state-run and have lower overhead. BAR 97 stations are private businesses and may charge more, but both produce the same official test result. Most Bakersfield stations are open Monday through Friday during business hours, with some offering Saturday morning appointments. Call ahead to confirm hours and whether you need a reservation, especially during peak testing periods (late summer and early fall).

Key Takeaways

  • You can find certified smog test stations in Bakersfield using the BAR station locator, which shows you location, hours, and phone numbers.
  • STAR stations are state-run and typically cost less than private BAR 97 stations, but both produce results the DMV accepts.
  • Your vehicle must pass the test that matches its model year and engine type — the station will know which test applies to your car.
  • Bring your vehicle registration and a valid ID; the test takes 30 minutes to an hour and results are sent to the DMV electronically.
  • If your vehicle fails, you have 30 days to repair it and retest at no additional cost at the same station.

What to bring and what the test covers

Bring your current vehicle registration and a valid photo ID. The station will use your registration to confirm your vehicle's model year, engine size, and transmission type — this determines which smog test your car must pass. California uses different tests for vehicles built in different years and with different powertrains, so the station staff will tell you which one applies.

The test itself measures your vehicle's exhaust emissions through a tailpipe probe. The technician will plug a hose into your tailpipe while the engine runs at idle and at a higher RPM, and the machine records whether your emissions fall within California's limits. The whole process takes 30 minutes to an hour. Results are sent electronically to the DMV the same day, so you do not need to deliver anything yourself.

Cost and payment at Bakersfield stations

STAR stations charge a state-set fee, which is currently $29.75 for most vehicles, though the exact amount can vary slightly by station and vehicle type. BAR 97 private stations set their own prices and typically charge between $40 and $60. Some stations accept cash, credit, and debit; call ahead if you want to confirm payment methods.

The fee covers one test only. If your vehicle fails, you can retest at the same station within 30 days at no additional charge. If you wait longer than 30 days to retest, you will owe the full fee again. Some stations offer discounts for seniors or low-income drivers — ask when you call to schedule.

What happens if your vehicle fails the smog test

If your vehicle fails, the station prints a detailed report showing which emissions exceeded the limit. You have 30 days from the test date to repair the vehicle and return to the same station for a free retest. The station keeps your original test on file, so you do not need to bring paperwork back.

Common repairs that help vehicles pass include replacing a faulty oxygen sensor, fixing a loose gas cap, or addressing engine misfires. If repairs are expensive, you may be able to use the Smog Check Repair information Program, which provides rebates for certain repairs on older vehicles. Contact the Kern County Air Quality Management District to learn whether your vehicle qualifies.

Smog test requirements for Bakersfield residents

Bakersfield is in Kern County, which is part of California's South Coast Air Quality Management District. Vehicles registered in Kern County must pass a smog test every two years if the vehicle is six model years old or newer. Vehicles older than that must test every year. Diesel vehicles have different testing rules and may require a different test type.

You must pass the smog test before you can renew your vehicle registration with the DMV. If your registration is about to expire and you have not yet tested, schedule your test soon — the DMV will not process your renewal until the test result appears in their system, which takes one to three business days after the station submits it.

How to schedule and prepare your vehicle

Call a STAR or BAR 97 station directly to schedule an appointment, or walk in during their open hours — most stations accept both. Before you go, make sure your vehicle's engine is in normal operating condition: the check engine light should not be on, your gas cap should be tight, and your engine should not be making unusual noises. If the check engine light is on, the station will fail your vehicle automatically, so have that diagnosed first.

Warm up your engine for a few minutes before you arrive at the station — the test works best on a warm engine. Do not arrive with a very cold engine or one that has been running hard, as both can skew results. If you are unsure whether your vehicle is ready, call the station and describe any symptoms; the technician can tell you whether it is worth coming in.

Retesting and what to do if you fail twice

If your vehicle fails the retest within 30 days, you can test again at no charge. However, if you fail a second time, you will owe the full test fee for any additional tests. At that point, you may want to take your vehicle to a repair shop for a diagnostic scan to identify the underlying problem before testing again.

If repairs are too expensive or your vehicle cannot pass even after repairs, you may be able to register it under a different program. Contact the Kern County DMV office to ask about conditional registration or other options for vehicles that cannot meet smog standards.

Frequently Asked Questions

Can I test my vehicle at a station outside Bakersfield?

Yes. You can test at any certified STAR or BAR 97 station in California, not just in Bakersfield. The result is valid for registration renewal in Kern County regardless of where you tested. Some people test at stations in less busy areas to avoid wait times.

What if my check engine light is on?

The station will fail your vehicle automatically if the check engine light is illuminated. Have the code read at a repair shop or auto parts store (many do this for free) and fix the underlying problem before you test. Once the light is off and the repair is confirmed, you can retest within 30 days at no charge.

How long does the smog test result stay valid?

The result is valid for 30 days. You must use it to renew your registration within that window. If your registration expires before you test, you cannot legally drive the vehicle, so plan ahead if your registration is about to expire.

Do I need an appointment or can I just walk in?

Most Bakersfield stations accept both walk-ins and appointments. Calling ahead is faster because you avoid wait times, especially during busy seasons. Some stations may require an appointment on certain days, so ask when you call.

What if the station says my vehicle cannot be tested?

A station may refuse to test if your vehicle is unsafe (brakes failing, steering problems, major fluid leaks) or if the test equipment cannot connect to your vehicle. In that case, have the safety issue repaired first, then return to test. If the problem is equipment-related, try a different station.
