CARB COMPLIANCE

Unless your truck is exempt from the regulation or has met the regulatory requirements, you will not be able to register your truck with the DVM beginning in 2020. In addition, you must verily your compliance with the California Air Resources Board’s (CARB) Truck and Bus Regulation.
Using the public information available on the CARB website, we have developed this Frequently Asked Question (FAQ) document for your convenience. You should always seek clarification with CARB or with the DMV. In no way does our information supersede the actual law or regulation. You will need to research this issue further to determine if your truck is affected.

What are the CARB requirements for my diesel truck?

In the past, dealers primary sold medium-duty trucks with a gross vehicle weight rating (GVWR) from 14,000 to 26,000 pounds, which this regulation addresses. You must replace any truck with a diesel engine that is 20 years or older with newer trucks (or engines). The regulation that begins on January 1, 2020, is about the replacement of all 2010 and older diesel trucks with newer 2010 model year diesel engines or equivalent emissions by January I, 2023. The regulation applies to nearly all diesel-fueled trucks with a gross vehicle weight rating (GVWR) greater than 14,000 pounds. If your truck is exempt from the regulation, or has met the regulatory requirements, you will be able to register with the DMV. Reporting fleet and vehicle information to CARB, such as VIN numbers, may be necessary to ensure that you are not mistakenly denied registration. The DMV will begin checking compliance with the regulation in order to register your vehicle based on the following schedule:

Lighter Vehicles (14,001- 26,000 lbs GVWR)

Vehicle Model Year DMV Begins Compliance Verification*
2004 and older – January 1, 2020
2005 – 2007 January 1, 2021
2008 – 2010 January 1, 2022

*You may already be out of compliance and currently subject to DMV registration holds.
What if I am currently out of compliance with the new CARB requirements?

CARB can place a DMV registration hold on your vehicle now if it does not meet current regulatory requirements.

Can I install PM filters on trucks that are required to upgrade to 2010 model year engines to be compliant?

No, owners who did not install PM filters before January 1, 2014 and do not use flexibility options must replace existing trucks (or engines) according to the applicable model year schedule above.
