If you have moved to California with a car registered in another state, you will usually need a California smog certification as part of registering it here. The DMV will also require a VIN verification.
This guide covers how those steps fit together for a new arrival in Modesto, without guessing at rules that depend on your exact vehicle.
Why the smog step comes up
California runs its own vehicle emissions program. A car registered for the first time in California, coming from another state, generally has to show it meets the state's smog requirements, unless it falls into an exempt category such as an electric vehicle or a gasoline vehicle from model year 1975 or older.
Your DMV paperwork is the authority on what applies to your vehicle. If you are unsure, ask the DMV before you assume an exemption.
VIN verification
Separate from the smog check, the DMV requires a vehicle identification number verification for vehicles previously registered out of state. It confirms the VIN on the car matches the paperwork. The DMV can tell you who is allowed to perform it.
What to bring to the smog appointment
Bring the vehicle and any DMV paperwork you have been given. Make sure the check engine light is off before you come in, because a lit check engine light is an automatic fail.
If the battery was disconnected during the move, or the car was shipped and has barely been driven, mention it when you call. The car's readiness monitors may need ordinary driving before it can be tested.

If it does not pass
An out-of-state car that has never been tested here can surprise you. At a test-only station a failure means finding a repair shop separately. At a Test & Repair station like CAR PRETTY on McHenry Avenue, the repair department on the same lot can diagnose the failure, repair it with your approval and retest the car at the same address.
