The station hands you the printout, and right there at the bottom it says FAIL. Your renewal notice is on the kitchen counter, the expiration date is coming up, and now you are wondering whether you will be able to register the car at all.
You have more options than most people realize. If you failed a smog check in California, you can repair and retest, apply for state repair money, retire the car for cash, ask a state referee for help, get a temporary permit to keep driving, or take the car off the road for a while. This guide from Arden Auto Reg in Sacramento walks through each one, so you can pick the path that makes sense for your car and your budget.
Failed Smog Check in California? Start With the Report
After every inspection, the station gives you a vehicle inspection report. It shows whether the car passed or failed and why. Read it before you spend a dollar on repairs, and ask the station to explain anything that is unclear.
According to the Bureau of Automotive Repair (BAR), some of the most common reasons cars fail are:
- Check engine light on. BAR says a vehicle will not pass with the check engine light on.
- Readiness monitors not set. If you recently disconnected or replaced the battery, BAR recommends driving for a week or two before testing so the system can reset.
- Modified software. Engine tunes that are not approved by the California Air Resources Board will cause a failure.
- Missing or altered emissions parts. The visual and functional inspection looks at the emissions control system itself.
- High tailpipe readings. Pre-2000 vehicles get a tailpipe emissions test. Most 2000 and newer vehicles are checked through the on-board diagnostic system.
Before paying for repairs, check your owner’s manual or warranty booklet. BAR notes that some emissions parts and repairs may be covered under warranty.
What a Failed Smog Means for Your Registration
In Sacramento County, most vehicles need a passing biennial Smog Check to renew. Gas vehicles less than eight model years old are exempt and pay a smog abatement fee instead. If your car needs smog and fails, the DMV will not finalize the renewal, even if you have already paid. That is the main reason people find they can’t renew registration after a failed smog.
Two things to do right away:
- Pay your renewal fees by the expiration date. California has no grace period. The DMV says that if you are missing a smog certificate, you should still pay on time to avoid penalties. You will get a receipt showing what is still needed.
- Do not drive on that receipt. The DMV is clear that it does not authorize operation of the vehicle. If you need to keep driving, look at the temporary permit option below.
If your expiration date has already passed, our post on missing your California renewal deadline explains the penalties and what to do next.
Option 1: Repair and Retest
For most drivers this is the simplest route. Get the car fixed, then retest. If your renewal notice says you must use a STAR station, go to one. If not, BAR says you can use any test-and-repair or test-only station.
A few things BAR wants you to know:
- Smog Check prices are not regulated by BAR and vary by station, so it pays to shop around.
- Stations charge an $8.25 state certificate fee on top of the inspection.
- Many shops offer a pretest, which can catch problems before the official inspection.
- When the car passes, the certificate goes to the DMV electronically and is valid for 90 days.

Option 2: Consumer Assistance Program Repair Help
BAR’s Consumer Assistance Program (CAP) offers smog repair assistance to income-eligible owners whose car failed its biennial inspection. BAR’s repair page currently lists help of up to $1,450 for 1996 and newer vehicles and up to $1,100 for 1976 to 1995 models. You pay a co-payment at the repair station, and amounts can change, so confirm the current figures with BAR.
Key eligibility points from BAR:
- Gross household income at or below 225% of the federal poverty level
- You are the registered owner, with the title in your name
- The car failed its biennial Smog Check and the emissions system has not been tampered with
- Registration is current, or fees are paid and the sticker has not been expired for more than 365 days
- The car is not registered to a business and is not in the middle of a transfer or new California registration
The big rule: do not start repairs until you receive your Letter of Eligibility. BAR will not reimburse repairs done before approval. CAP repairs are done at STAR test-and-repair stations. That same letter also waives the $50 DMV fee for a smog temporary operating permit. For more details on navigating registration renewal costs and smog requirements, check our guide on California DMV smog fees and requirements.
Option 3: Retire the Vehicle
If repairs cost more than the car is worth, CAP also pays you to retire it at a BAR-contracted dismantler. BAR currently lists three incentives:
| Incentive | Income requirement | Smog requirement |
|---|---|---|
| $1,350 | None | Failed its most recent Smog Check |
| $1,500 | At or below 225% of federal poverty level | Smog Check completed (pass or fail) within 180 days before applying |
| $2,000 | At or below 225% of federal poverty level | Failed its most recent Smog Check |
The car has to be in your name, driven to the dismantler under its own power, and have its basic parts like doors, windshield, seats and lights. Registration also matters. BAR generally requires the car to be currently registered, or fees paid with the sticker expired no more than 120 days, plus no long lapses in the prior two years. Do not let the registration sit expired too long if retirement is on the table.
Option 4: Contact the Smog Check Referee
The BAR referee program is a neutral resource. The DMV suggests contacting the Referee if your car fails, and BAR says Referees help with inspection results you disagree with, unusual vehicles such as engine changes or specially built cars, and hard-to-find emissions parts. If a station refuses to test your car, BAR also points you to the Referee. For a complete checklist of documents and steps to get your tags current, read our guide on CA DMV vehicle registration checklists.
Option 5: Get a Temporary Operating Permit
If you need to keep driving to work while repairs happen, the DMV offers a biennial smog TOP. You need your renewal fees paid, the failed inspection report and proof of insurance, plus a $50 fee unless you have the CAP letter. It is valid for 60 days from your registration expiration date, not from the day you get it, and only one is allowed per vehicle every two years. Our full guide on the temporary operating permit explains the details.
Option 6: Planned Non-Operation
If you are not going to drive the car for a while, maybe it is a project truck sitting in the garage in Arden-Arcade, Planned Non-Operation (PNO) stops the registration fees. The DMV accepts PNO filings up to 60 days before expiration or up to 90 days after, with penalties if you file late. The car cannot be driven, towed, stored or parked on public roads while on PNO, and that includes the street in front of your house. Read our guide to Planned Non-Operation in California before you file.
Selling a Car That Failed Smog
Thinking about just selling it? Be careful. The DMV says that when you sell a car, you need to give the new owner a valid smog certification. Writing “as is” on the bill of sale does not change that requirement. Cars less than four model years old are the exception, since the buyer pays a smog transfer fee instead.
Realistic options for a car that will not pass include fixing it first, retiring it through CAP, or selling it to a licensed dismantler. If you do sell, the paperwork still matters. Our post on how a title transfer works covers what both sides need.
Common Mistakes to Avoid
Starting CAP repairs before approval. BAR will not pay for work done before your Letter of Eligibility arrives.
Missing the renewal deadline while you sort it out. Pay your fees on time to avoid penalties, even before the car passes.
Testing right after a battery change. Give the readiness monitors time to reset.
Waiting too long for a TOP. The 60-day smog TOP window runs from your expiration date.
Letting registration lapse when you might retire the car. CAP has registration limits, so a long lapse can cost you the incentive.

Frequently Asked Questions

How long is a passing smog certificate good for?
BAR says the certificate is sent to the DMV electronically and is valid for 90 days.
Can I get money to fix my car?
Possibly. BAR’s Consumer Assistance Program offers repair assistance to income-eligible owners whose car failed its biennial Smog Check.
Can I sell a car that failed smog?
The DMV says sellers must provide a valid smog certification, with an exception for cars less than four model years old. Retiring the car or selling to a licensed dismantler are other options.
