Buying or Selling a Diesel Truck in California? What You Need to Know About Clean Truck Check Compliance

If you are buying or selling a diesel-powered commercial vehicle in California, understanding California’s Clean Truck Check requirements is extremely important. Many truck owners are unaware that Clean Truck Check compliance can directly impact DMV transactions, vehicle transfers, and registration processing.
According to guidance provided by the California Air Resources Board (CARB), vehicles subject to Clean Truck Check must be compliant within 90 days before the transfer of ownership. This means buyers and sellers should verify compliance before completing a sale to avoid unexpected delays or compliance issues.
For buyers, one of the most important steps is requesting the vehicle’s most recent compliance certificate before purchasing the truck. CARB recommends reviewing the issue date on the certificate to confirm the vehicle was compliant within the required timeframe before ownership transfer.
After purchasing the vehicle, the buyer must report the truck to their CTC-VIS account as soon as possible and no later than 30 days after the purchase date. If the vehicle was compliant within the required 90-day period, the new owner may be able to download the compliance certificate within 24 hours after successfully reporting the vehicle in the system.
Sellers also have important responsibilities under the Clean Truck Check program. Once ownership is transferred, sellers are required to deactivate the vehicle from their CTC-VIS account. This helps prevent duplicate VIN issues inside the CARB system and ensures the vehicle is properly assigned to the new owner.
Many buyers encounter problems during DMV registration because the vehicle does not appear compliant in the CARB system. CARB notes that vehicles generally need to show compliant status in the account for at least one business day before completing most California DMV transactions. If the vehicle shows “non-compliant,” the owner should review the compliance reason within the account immediately.
