California Clean Truck Check (HD I/M) Program: Key Points for Your Fleet

The California Air Resources Board (CARB) launched the Clean Truck Check program to tackle air pollution from heavy-duty vehicles. Here's a breakdown of key points for fleet owners like you:

Who it Applies To:

Nearly all diesel and alternative fuel heavy-duty vehicles with a Gross Vehicle Weight Rating (GVWR) exceeding 14,000 pounds operating on California roads.
This includes in-state, out-of-state, public and private fleets.

Compliance Requirements

Before Compliance Testing:
- Report Vehicles: Submit information on your applicable vehicles to CARB.
- Annual Compliance Fee: Pay a yet-to-be-determined annual fee to CARB.
- Prepare for Testing: Familiarize yourself with the testing procedures (details available on CARB's website).
During Compliance Testing:
- Testing Frequency: Frequency will depend on vehicle type, age, and model year (specifics to be announced by CARB).
- Testing Procedures: Likely to involve on-board diagnostic (OBD) data checks and emission testing at certified stations.

Clean Truck Check - Heavy-Duty Inspection and Maintenance (HD I/M) Program

The Clean Truck Check program aims to lower emissions from diesel vehicles that operate in California even further. This program targets heavy-duty vehicles like trucks buses, and motorhomes, ensuring they’re running clean and efficiently. One key point to be aware of is that the Clean Truck Check (CTC) regulations apply to all trucks operating in the state, not just trucks based in California.

Deadline Update for Clean Truck Check Reporting: The California Air Resources Board (CARB) is extending the Clean Truck Check reporting deadline to January 31, 2024, to allow vehicle owners additional time to complete their initial fleet reporting and meet the compliance fee requirement.

Database Reporting CTC-VIS

Vehicle owners (or designees) will be required to report in 2024 in the Clean Truck Check database when creating their accounts to comply with the Heavy-Duty Vehicle Inspection and Maintenance regulation. Required information must be entered for vehicles in your fleet that are subject to Clean Truck Check with a $30 per vehicle compliance fee(s) paid for all vehicles in the fleet by January 31, 2024.

Fleet DMV Database Registration 12/31/2023

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.
