Vehicle Inspection Rules in California, and What We Check Instead
California does not have a periodic vehicle safety inspection, so there is no annual or biennial safety certificate to obtain here as in many other states. What California does require is a Smog Check for most vehicles, and Five Points Tire can carry out a voluntary safety inspection any time you want the car properly looked over.
Vehicle inspection in California at Five Points Tire, in short
California has no periodic vehicle safety inspection, so there is no annual or biennial certificate to obtain here. What the state requires is a Smog Check for most vehicles at registration renewal. Five Points Tire in Redwood City carries out voluntary safety inspections any time you want the car properly looked over, which is the only thing that checks brakes, tires, steering and suspension.
Short answer: no. California has no periodic vehicle safety inspection.
There's no annual sticker, no biennial safety certificate, and no state inspection station to visit. If you've moved here from a state that requires one, the requirement simply does not exist here.
What California does require is a Smog Check, which is an emissions test and looks at nothing else. The rest of this page is the detail, and what it means for a car you actually depend on.
What California requires, and what it doesn't
California requires a Smog Check for most vehicles and no periodic safety inspection at all, where most states bundle the two into one annual visit.
The Smog Check falls every other year at registration renewal, on a change of ownership, and when a vehicle is first registered here from out of state.
It reads the emissions systems and the on-board diagnostics. It does not look at your brakes, your tires, your steering, your suspension or your lights, and it is not intended to.
So a car can pass everything California asks of it while being genuinely unsafe, and nothing in the process would catch that.
The gap that leaves is worth naming. Because nothing in California forces anyone to have brakes, tires, steering or suspension examined on a schedule, a great many cars on the road here have never had a safety check at all. Voluntary inspection is the only thing that closes it.
Signs you need a voluntary inspection
- You have moved to California from a state with annual safety inspections
- You are registering an out-of-state vehicle in California for the first time
- You are buying a used car and want it checked before you commit
- You are selling a car and want to know what a buyer will find
- Your registration renewal has arrived and you are not sure what is required
- You want the car checked over before a long trip
What California actually requires
| Requirement | Does California have it? | Detail |
|---|---|---|
| Annual safety inspection | No | There is no periodic safety inspection program |
| Safety inspection certificate | No | Nothing to display and nothing to renew |
| Smog Check | Yes, most vehicles | Generally every two years at registration renewal |
| Smog Check on sale | Yes | Required on change of ownership |
| VIN verification | Yes, once | When first registering an out-of-state vehicle |
| Voluntary inspection | Optional | The only thing that checks brakes, tires and suspension |
If you have moved from a state with annual safety inspections, that requirement does not exist here.
Bringing a car in from another state
Registering an out-of-state car takes a VIN verification at the DMV plus a Smog Check, and neither one examines anything mechanical.
The verification, done on the REG 31 form, confirms the car is the car the paperwork describes. The Smog Check applies to gasoline vehicles from 1976 and diesels from 1998 under 14,001 lbs.
Get the smog side done before your DMV appointment rather than after. It's the part that can send you away and make you come back.
The one safety inspection California does have
Revived salvage and junk vehicles, kit cars, trailers over 3,000 pounds and off-highway vehicles converted for the street all need a Vehicle Safety Systems Inspection certificate before they can be registered.
That one is a real safety examination. It covers body structure, brakes, lighting, the passenger compartment including seat belts and airbags, steering, suspension, tires and wheels, plus an on-board diagnostics scan, a safety recall check and a road test.
It replaced the old brake and lamp certificates, and paper certificates issued from late September 2024 are no longer accepted. It has to be done at a station licensed for it, and it is a one-time requirement rather than a recurring one.

The gap that leaves, and what to do about it
Unless your car is a revived salvage, nothing in California requires anyone to have their brakes looked at, ever.
Plenty of cars on the road here have never had a safety check of any kind. Not because their owners are careless, but because no process ever prompted one.
That's the gap a voluntary inspection closes, and the moments it's worth doing are specific rather than constant: before you buy a used car, before you sell one, before a long drive, and when you've just moved here and the annual check you were used to has stopped happening.
If you want the full list of what gets measured and how, that's on our vehicle inspection page. It is the same examination, done because you want to know rather than because the state asked.
Common assumptions about California inspections
- Looking for a state inspection station. There isn't one. California licenses Smog Check stations, and that is a different thing.
- Assuming the Smog Check covers safety. It reads emissions and on-board diagnostics. Brakes, tires, steering and suspension are not part of it.
- Booking the DMV appointment before the smog test. The smog certificate is the part that sends people away. Do that side first.
- Thinking a smog pass means the car is fine. It means the emissions systems work. It says nothing at all about whether the car stops.
- Skipping an inspection on a used car because the state doesn't ask for one. Nobody is going to check it for you here. That is the whole point of this page.
The bottom line
California has no periodic safety inspection, so there's nothing you're forgetting and no certificate you're missing.
Check whether your vehicle needs a Smog Check this cycle, and get that done before any DMV appointment.
Then decide separately whether the car has ever actually been looked over, because nothing in the state process will decide that for you.
When you want that done, our vehicle inspection page sets out what Five Points Tire measures. Call 650-365-0280 with any question about what California requires.
Vehicle inspection in California questions we get asked
Question not on the list? Ask us directly.
Does California require a vehicle safety inspection?
- No. California has no periodic vehicle safety inspection program. There is no annual or biennial safety certificate here. The state requires a Smog Check for most vehicles, which is an emissions test and does not assess brakes, tires, steering or lights.
I moved to California. Do I need a state inspection?
- Not a safety inspection, because California does not have one. Registering an out-of-state vehicle here does require a VIN verification and, for most vehicles, a Smog Check, both handled as part of DMV registration.
What does California require instead?
- A Smog Check for most vehicles, generally every two years at registration renewal, on change of ownership, and on first registration in California. That is the only mandatory periodic inspection in the state, and it covers emissions only.
Should I still get my car inspected if the state does not require it?
- It is worth it, precisely because nothing else will prompt it. Brakes, tires, steering and suspension all wear gradually enough that you adapt to them without noticing. An inspection is also the standard move before buying a used car. Five Points Tire carries out a voluntary inspection any time you want the car properly looked over.

Vehicle Inspections
California does not require a periodic safety inspection, so a voluntary check is the only thing that catches brake, tire, steering and suspension wear before it becomes a failure.
Smog Check Repair
If your vehicle has failed its California Smog Check, or the check engine light is on with a smog test due, the underlying fault has to be found and repaired before it can pass.
Brakes
If your brakes squeal, grind, pull to one side, or the pedal sinks further than it used to, have them inspected straight away rather than waiting to see if it settles.
Headlamp Replacement
A headlight that has failed, or a lens so clouded it is throwing away most of its light, is both a safety problem and something you can be pulled over for.
Wiper Blades
Wiper blades are rubber left out in the sun, so they harden and split whether you use them or not, and they usually fail right when the first serious rain arrives.
Suspension Services
Your suspension keeps the tires in contact with the road and absorbs what the road throws at the car, so when parts of it wear you lose ride quality, steering precision and grip together.
