California Air Resources Board

This guidance document provides reporting information on the Clean Truck Check, Vehicle Inspection System (CTC-VIS). This reporting database (CTC-VIS) is available at cleantruckcheck.arb.ca.gov. Any vehicle(s) subject to Clean Truck Check must be reported in the database by December 31, 2023. The initial annual compliance fee for each reported vehicle must be paid by December 31, 2023. In 2024, since there is only one emissions testing requirement that year, it must be paid by the last day of the month as noted in the table below.

Beginning in 2025, the compliance fee must be paid annually every "compliance year", which is the year between CA DMV registration expiration dates and for out-of-state or DMV Exempt vehicles, you use the table below to determine the expiration date (last day of the month in table) based on the last number of the vehicle's VIN.

Please note that CTC-VIS is separate from other California Air Resources Board (CARB) reporting databases, such as the Truck Regulation Upload, Compliance and Reporting System (TRUCRS). A new account will need to be created to report owner information and vehicle information for all vehicles operating in California. Vehicle information for the fleet can be downloaded from TRUCRS and then uploaded to CTC-VIS to allow for a more convenient reporting method if a TRUCRS account has been created for the fleet. Changes to the fleet operating in California (adding or deleting a vehicle) must be reported within 30 days of the action. 

The annual 30 dollar per vehicle compliance fee must also be paid in this system. Payments can be made via credit card, debit card, or e-check. CARB anticipates payment methods becoming available no earlier than October 16, 2023, at which time, a batch payment option will also be available.
