Print Print this Article | Send to Colleague

*Diesel trucks with a GVWR of more than 14,000 pounds that are privately and federally owned fleets are subject to the Truck & Bus Regulation. Do you own a lighter diesel truck that is a 2004 or older model year? Upcoming compliance deadlines may affect you.

What are the Truck & Bus compliance requirements?
If you own a lighter diesel vehicle (14,001-26,000 pounds GVWR) that is a 2004 or older model  year (MY) vehicle, you have an upcoming compliance deadline of January 1, 2020.
You must comply in one of the following ways:
  • Remove the vehicle from the fleet – OR-
  • Replace or repower the vehicle with a 2010+ MY engine
The Truck and Bus Regulation has compliance requirements that apply today. 
Failure to comply with the regulation is a violation of state law and is subject to penalties and registration holds. CARB is actively enforcing this regulation.

What is the new law?
Starting in 2020, vehicles subject to CARB’s Truck & Bus Regulation must meet the requirements of the regulation prior to obtaining registration through the DMV.

Do you own additional lighter vehicles subject to the Truck & Bus Regulation?
If you own additional lighter vehicles with vehicle model years not mentioned in this article, there may be future deadlines you must meet. Note that there are different compliance deadlines for heavier diesel vehicles (26,001+ pounds GVWR). Visit the Truck Stop website at for more information.

Is there funding for early compliance?
If you won a vehicle with a compliance date in 2020 or later, now is the time to apply for funding opportunities that may be available for purchase of a newer, cleaner vehicle. Visit the TruckStop website’s "Financial Assistance" section for more information.
