Do I Need a Change of Ownership Smog Check?
In many California vehicle sales, a valid smog certification is required before ownership can be transferred. In most private-party transactions, the seller is responsible for providing a current smog certificate unless an exemption applies.
If you're unsure whether your vehicle requires a smog inspection before the transfer, bring your paperwork or contact our team. We'll help determine the correct inspection based on your situation.
For official requirements, visit the California Department of Motor Vehicles (DMV) or the Bureau of Automotive Repair (BAR).

Do You Need a Change of Ownership Smog Check?

Why Is a Smog Certificate Required?
California requires emissions inspections for many vehicle transfers to help ensure qualifying vehicles continue meeting state emissions standards. A current smog certificate helps protect both buyers and sellers by documenting that the vehicle passed the required emissions inspection at the time of the transaction.
Once your vehicle passes the inspection, we electronically transmit the results to the California DMV, making the registration process faster and more convenient.
