California’s Clean Truck Revolution: How the Advanced Clean Trucks Rule is Reshaping Commercial Fleet Operations in 2024
Commercial fleet owners across California are facing unprecedented changes as the state’s Advanced Clean Trucks (ACT) regulation takes full effect in 2024. This groundbreaking environmental policy is fundamentally transforming how businesses operate their medium and heavy-duty vehicle fleets, creating both challenges and opportunities for companies throughout the Golden State.
Understanding the Advanced Clean Trucks Rule
The Advanced Clean Trucks regulation is a manufacturers ZEV sales requirement and a one-time reporting requirement for large entities and fleets. The ACT regulation requires increasing percentages of manufacturer sales of on-road medium- and heavy-duty vehicles from Class 2b to Class 8 to be zero-emission vehicles (ZEVs). By model year 2035, zero-emission sales would need to be 55% of Class 2b-3 vehicle sales, 75% of class 4-8 vehicle sales, and 40% of Class 7-8 truck tractor sales.
The regulation operates on a credit and deficit system, where deficits are generated by selling vehicles into the state; credits are earned by selling ZEVs or near-ZEVs (NZEVs). This market-based approach incentivizes manufacturers to accelerate their production of clean commercial vehicles.
Fleet Owner Requirements and Reporting Obligations
For commercial fleet operators, the ACT rule brings specific compliance requirements. Fleet owners, with 50 or more trucks, are required to report about their existing fleet operations. This information will help identify future strategies to ensure that fleets purchase available zero-emission trucks and place them in service where suitable to meet their needs.
The reporting requirements are designed to provide state regulators with crucial data about how commercial fleets operate, enabling more targeted policy development. Entities with more than $50 million in gross annual revenue with at least one vehicle with a gross vehicle weight rating (GVWR) greater than 8,500 pounds fall under these reporting obligations.
The Advanced Clean Fleets Complement
Working alongside the ACT regulation, California has also implemented the Advanced Clean Fleets (ACF) rule, which directly targets fleet composition. The ACF requires fleet operators to begin incorporating zero-emission vehicles into their fleets as early as January 1, 2024. Under the ACF, owners of these vehicles are required to begin their transition to zero-emission vehicles, with the first compliance period deadline set at January 1, 2024.
State and local agencies: California State and local government fleets, including city, county, special district, and State agency fleets, would be required to ensure 50 percent of vehicle purchases are zero-emissions beginning in 2024 and 100 percent of vehicle purchases are zero-emissions by 2027.
Economic Impacts and Benefits
While the transition requires significant upfront investment, the long-term economic benefits are substantial. Fleet owners will save an estimated $48 billion in their total operating costs from the transition through 2050. Additionally, the new rule is expected to generate $26.6 billion in health savings from reduced asthma attacks, emergency room visits and respiratory illnesses.
Zero-emission trucks have higher upfront costs but have lower operating costs than conventional trucks. Today, the total cost of ownership in California can be comparable to conventional trucks for certain duty cycles without grants or rebates. Various incentive programs are available to help offset initial costs, making the transition more financially viable for fleet operators.
Compliance Flexibility and Support
Recognizing the challenges of transitioning to clean technology, the regulations include several flexibility mechanisms. With the implementation of the ACF, your existing fleet vehicles are allowed to remain in use for the next 18 years, or until they reach 800,000 miles. This will allow you to gradually phase in zero-emission vehicles (ZEVs) to meet the compliance standards of the ACF without having to reconstruct your entire fleet at once.
The California Air Resources Board (CARB) recognizes that potential delays are outside of a fleet’s control, so ACF provides some flexibility regarding delays that fall into four categories: Infrastructure delays: If a fleet begins to plan a project to comply with an ACF but is unable to do so due to construction delays, the fleet may apply for an extension delaying ZEV adoption for one year. Electrical delays: If a fleet signs a utility contract and the utility needs more time to make the needed electrical upgrades, the fleet may delay ZEV adoption.
Emissions Testing and Compliance Verification
As California’s clean truck regulations reshape the commercial vehicle landscape, proper emissions testing and compliance verification become increasingly critical. Fleet owners need reliable partners to ensure their vehicles meet all state requirements, whether they’re operating traditional diesel trucks during the transition period or implementing new zero-emission technologies.

These services help fleet operators navigate the complex requirements while maintaining operational efficiency during the transition to cleaner technologies.
Looking Ahead: Industry Transformation
There are more than 70 different models of zero-emission vans, trucks and buses that already are commercially available from several manufacturers. Most trucks and vans operate less than 100 miles per day and several zero-emission configurations are available to serve that need. As technology advances, zero-emission trucks will become suitable for more applications.
The regulatory framework represents more than just environmental policy—it’s a comprehensive economic transformation that positions California as a leader in clean transportation technology. By implementing ACT, California expects to accelerate medium- and heavy-duty ZEV truck adoption and cut up to 17 million tons of CO2 emissions by 2040. Accelerated ZEV adoption can yield substantial economic and health benefits to local economies and citizens.
For commercial fleet owners, 2024 marks the beginning of a new era in transportation. While the transition presents challenges, it also offers opportunities for cost savings, improved air quality, and positioning businesses at the forefront of sustainable logistics. Success in this new landscape requires proactive planning, strategic partnerships, and a commitment to embracing clean technology solutions that will define the future of commercial transportation in California.
