Fleet Reporting Systems
CARB uses four separate reporting databases for vehicle manufacturers and fleet owners to verify compliance several of CARB’s mobile source emission reduction rules and regulations. These reporting systems include Advanced Clean Fleets and Truck & Bus (TRUCRS), Clean Truck Check (CTC-VIS), Off-Road Diesel (DOORS) and Advanced Clean Trucks (ACTRS).
- Many entities will be required to report to multiple systems
- A new account may need to be created to report owner and vehicle information for all California vehicles operating in California for each reporting system.
- If a TRUCRS account has been created for the fleet, vehicle information for that fleet can then be downloaded from that TRUCRS account as a CSV file and then uploaded to CTC-VIS for a more convenient reporting method.
- Changes to the fleet operating in California (adding or deleting a vehicle) must be reported within 30 days of the action.
TRUCRS Reporting System for Advanced Clean Fleets and Truck & Bus
Truck & Bus applies to diesel vehicles with a GVWR greater than 14,000 lbs., privately and federally owned trucks and buses that operate in California, and any person, business, school district, tribal reservation, or federal government agency that owns, operates, leases or rents affected vehicles.
Advanced Clean Fleets applies to medium- and heavy-duty on-road vehicles with a GVWR greater than 8,500 pounds, off-road yard tractors, and light-duty mail and package delivery vehicles. This includes trucks performing drayage operations at seaports and railyards, fleets owned by State, local, and federal government agencies, and high priority fleets.

DOORS Reporting System for Off-Road Diesel Regulation
The Off-Road Diesel regulation applies to public, private, and government fleets who own or operate off-road diesel vehicles with engines 25 horsepower or greater (like backhoes and loaders) in California. Agricultural vehicles are exempted. Reporting is required through the DOORS system, which is an online tool to help vehicle owners report vehicle inventories and actions taken to reduce vehicle emissions.
Reporting Deadlines for the Off-Road Diesel Regulation
- March 1st each year: Complete annual reporting requirements and submit the Responsible Official Affirmation of Reporting (ROAR) form
