What All Star Smog Does

All Star Smog is a California-based smog check station that tests whether your vehicle meets state emissions standards. They perform the actual inspection — measuring your car's exhaust output against California Air Resources Board (CARB) limits — and issue the certificate you need to register or renew your vehicle registration with the Department of Motor Vehicles (DMV).

All Star operates as a licensed smog check provider, meaning they follow the same testing protocols and use the same equipment calibration standards as any other certified station in California. They do not set the emissions standards themselves; those come from CARB. What they do is run the test, record the results, and submit the pass or fail electronically to the DMV.

The station handles both initial inspections (when you first need a smog check) and repair verifications (when you failed a previous test, had your vehicle repaired, and need to prove it now passes). They also perform out-of-state vehicle inspections for people moving to California who need to register their car here.

Key Takeaways

  • All Star Smog is one of thousands of licensed stations in California; the test itself is the same regardless of which station you choose.
  • You need a smog check before you can register a new vehicle in California or renew registration on most vehicles older than four years.
  • The test takes 30 to 60 minutes and costs between $30 and $70, depending on your vehicle type and whether it is a basic test or a repair verification.
  • If your vehicle fails, you have 30 days to repair it and return to any smog check station (not necessarily All Star) for a retest.
  • All Star submits your results electronically to the DMV, so you do not need to carry a paper certificate to the DMV yourself.

When You Need a Smog Check

California requires a smog check in specific situations. If you are registering a vehicle for the first time in California, you need one. If you are renewing registration on a vehicle that is four years old or older, you need one every two years. Vehicles three years old or newer are exempt from smog checks for the first four years of ownership.

You also need a smog check if you failed one previously and had repairs done. In that case, you return for what is called a repair verification inspection to prove the vehicle now passes. Some vehicles — including those with a gross vehicle weight rating over 14,000 pounds, motorcycles, and certain other categories — have different or no smog check requirements, so check your registration notice or call the DMV if you are unsure.

The timing matters: you can have a smog check done up to 90 days before your registration expires, but not before. If you do it too early, the results will not be valid when you try to register.

What Happens During the Test

When you arrive at All Star Smog, you will provide your vehicle keys and registration. The technician will verify your vehicle identification number (VIN) matches your paperwork, then connect your car to a dynamometer (a machine that simulates driving) or perform a static test, depending on your vehicle's year and type.

The test measures hydrocarbons, carbon monoxide, and nitrogen oxides in your exhaust. For most vehicles, the test takes 30 to 60 minutes. You will wait in the station while the test runs. Once complete, the technician will tell you whether you passed or failed and print a receipt showing the results.

If you pass, All Star submits the certificate electronically to the DMV under your name and vehicle information. You can then go to the DMV (or use their online system) to renew your registration. You do not need to bring a paper certificate with you; the DMV will see the record.

What to Do If Your Vehicle Fails

A failed smog check does not mean your vehicle cannot be registered — it means you have 30 days to repair it and return for a retest. You can take your vehicle to any repair shop you choose; it does not have to be affiliated with All Star or any particular station. Many shops specialize in emissions repairs and can often diagnose the problem quickly.

Common reasons for failure include a faulty oxygen sensor, a loose gas cap, a malfunctioning catalytic converter, or an engine light that is on. Some repairs are inexpensive (a gas cap might cost $10 to $20); others are more costly. If you are unsure what is wrong, ask the smog check station for a printout of the specific emissions readings — this helps a repair shop narrow down the problem.

After repairs, you return to any licensed smog check station for a repair verification inspection. This test is the same as the initial test. If you pass, the station submits the new certificate to the DMV. If you fail again, you have another 30 days to repair and retest.

Cost and Location Details

All Star Smog's pricing varies by location and vehicle type. A basic smog check typically costs between $30 and $70. A repair verification inspection may cost slightly more or the same, depending on the station's pricing structure. Some stations offer discounts for seniors or military personnel, so it is worth asking when you call.

All Star operates multiple locations throughout California. You can find the nearest one by searching online or calling their main number. You do not need an appointment at most locations, but calling ahead to confirm hours and current wait times is a good idea, especially during peak registration renewal periods.

Payment methods vary by location, but most accept cash, debit, and credit cards. Some locations may require payment upfront; others may bill after the test is complete. Ask when you arrive or call ahead.

Your Rights and Options

You have the right to choose any licensed smog check station in California — All Star is one option, but you can go to any station certified by CARB. The test results are the same regardless of which station performs it. If you are unhappy with a result or believe the test was performed incorrectly, you can request a retest at a different station within 30 days at no additional cost to your registration timeline.

If you believe All Star made an error in testing or reporting, you can file a complaint with the Bureau of Automotive Repair (BAR), which oversees smog check stations. The BAR investigates complaints about testing practices, equipment calibration, and fraud.

You also have the right to see your test results before the station submits them to the DMV. Ask for a printout showing the specific emissions readings and whether you passed or failed. This information helps you understand what repairs, if any, are needed.

Frequently Asked Questions

Can I get a smog check at All Star if I do not have my registration with me?

You will need your vehicle registration or proof of ownership to get a smog check. If you have lost your registration, contact the DMV first to request a replacement. Some stations may accept a bill of sale or other proof of ownership in limited circumstances, but registration is the standard requirement.

What if I fail the smog check but cannot afford repairs right away?

You have 30 days from the test date to repair and retest. If you cannot complete repairs within that window, your registration will expire and you will need to renew it again later. There is no extension process, but you can reapply for registration once repairs are done. Some nonprofits and local programs offer repair cost information for low-income vehicle owners; contact your county's environmental or transportation department to ask.

Do I need to go back to All Star for the retest, or can I go to a different station?

You can go to any licensed smog check station for a repair verification inspection. You do not have to return to All Star. All stations use the same testing standards and submit results to the DMV the same way.

How long does it take to get my smog check results after the test?

All Star submits results electronically to the DMV when ready or within one business day. You can usually see the result in your DMV online account within 24 hours. You do not need to wait for a paper certificate.

What if my vehicle is very old — will All Star test it?

All Star will test any vehicle that is subject to California smog check requirements. Vehicles 1975 and older are generally exempt. Vehicles between 1976 and the current year are subject to smog checks based on their age and registration status. Call All Star or the DMV if you are unsure whether your specific vehicle needs a test.
