Vehicle owners are required to report vehicles subject to the Clean Truck Check program in the Clean Truck Check – Vehicle Inspection System (CTC-VIS) reporting database . 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 2023 compliance fee payment requirements.

The Clean Truck Check program applies to nearly all diesel and alternative fuel heavy-duty vehicles with a gross vehicle weight rating (GVWR) over 14,000 pounds that operate in California. This includes both in-state and out-of-state vehicles, as well as public vehicles (federal, state, and local government); motorcoaches; transit, shuttle and school buses; hybrid vehicles; commercial vehicles; personal vehicles; California-registered motorhomes; single vehicle fleets; and vehicles registered outside of California (not including motorhomes).

The Clean Truck Check program does not apply to:

  • Zero-emission vehicles,
  • Gasoline vehicles,
  • Military tactical vehicles,
  • Authorized emergency vehicles,
  • Motorhomes registered outside of California,
  • Historical vehicles,
  • Vehicles operating under a CARB-issued experimental permit, and
  • Vehicles operating under an Executive Order or Emergency Declaration.

North Bay Truck Center has installed the state of the art FSX Diesel Particulate Filter (DPF) cleaning equipment to help our customers keep their engines performing effectively by removing up to 94% of the captured soot from the DPF filter. Cleaner DPF equals longer filter life too and these filters are very expensive to replace.

Diesel Particulate Filters are quite expensive to replace and can be regenerated by periodic deep cleaning. This will enhance the performance of your truck’s exhaust system and help your truck get maximum fuel economy and effectiveness. Your DPF filter may only need cleaning every 250,000 miles or much sooner depending on your engine and how it is maintained.

Dirty exhaust means the soot will clog the filter sooner, so you will want to make sure that your engine is serviced regularly. Every truck will be different as every driver is different.

We chose FSX because FSX has a proven cleaning method that gets the most soot out of the filter and North Bay Truck Center has installed the complete cleaning system including the TrapBlaster™ Pneumatic Cleaner, TrapTester™ Air Flow Test Bench, TrapBurner™ Thermal Cleaner, and SootSucker™ Dust Collector.
