The California Air Resources Board (CARB) staff invite you to participate in the first of several public online training webinars on the new Advanced Clean Fleets (ACF) regulation.

This webinar will be held via Zoom at the following time. Interested parties must register to participate. This meeting will be recorded and made available on the ACF website.

Date:                October 18, 2023
Time:                09:00 a.m. – 12:00 p.m. (Pacific Time)
Location:          Register for Zoom


This free online training is open to the public and will provide an overview of the ACF regulation, cover who is affected, and outline the upcoming compliance requirements. The focus of the webinar will be solely on the ACF regulation.

We anticipate a large number of participants and questions. In order to facilitate an efficient discussion, we request that questions be submitted in advance. Staff will review the questions, compile those that are similar and pertinent to the ACF regulation, and provide answers during the webinar. While we will not be able to answer detailed questions specific to your fleet only, we will provide information on how to get individualized fleet assistance. If time allows, we will answer clarifying questions at the end of the presentation. Please submit your questions through the Zoom registration page no later than Wednesday, October 11, 2023.

After registering for the event using the link above, participants will have the option to participate via Zoom or access the meeting by telephone with a dial-in number. CARB staff highly recommends participating using the Zoom Desktop or Mobile App for best quality and interactive participation.

CARB has several resources available that will help prepare you for this training:

We encourage you to review these documents beforehand in order to ensure the most collaborative and informative experience. Please note that your vehicle or fleet may be affected by several other CARB regulations that are currently in place. Visit our TruckStop page to learn more about new California requirements for heavy-duty vehicles.


To meet California's health-based air quality standards and greenhouse gas emission reduction goals, the trucks and buses operated in the state and the fuel they use must be transformed away from petroleum. California is working to meet the Governor’s goal of one hundred percent zero-emission transportation where feasible by 2045.

The ACF regulation applies to fleets performing drayage operations, those owned by State, local, and federal government agencies, and high priority fleets. High priority fleets are entities that own, operate, or direct at least one vehicle in California, and that have either $50 million or more in gross annual revenues, or that own, operate, or have common ownership or control of a total of 50 or more vehicles (excluding light-duty package delivery vehicles). The regulation affects medium- and heavy-duty on-road vehicles with a gross vehicle weight rating greater than 8,500 pounds, off-road yard tractors, and light-duty mail and package delivery vehicles.
