If you own a 2010 or older model year diesel truck, your truck is no longer compliant and DMV registration may be denied in 2023.

The California Air Quality Board’s (CARB) regulations on mobile sources are changing consumer behavior, business decisions, and government actions like never before. Key changes began 2 years ago, with the Advanced Clean Truck (ACT) regulation which required manufacturers to sell zero-emission trucks as an increasing percentage of their annual California sales from 2024 to 2035. This regulation also required government fleets and large entities that operate or dispatch vehicles with a manufacturer’s gross vehicle weight rating (GVWR) of over 8,500 lbs in California to submit a one-time report to CARB. The regulation affects medium- and heavy-duty trucks, off-road yard trucks and light-duty mail and package delivery vehicles.
The following is a summary of the proposed requirements:
- Manufacturers may only sell zero-emission medium- and heavy-duty vehicles starting 2040.
- State and local government fleets, including county, special district, and state agency fleets, would be required to ensure 50 percent of vehicle purchases are zero-emission beginning in 2024 and 100 percent of vehicle purchases are zero-emission by 2027.
- For drayage fleets, starting 2024, only zero-emission trucks may be added to drayage service and legacy vehicles must be removed from drayage service at the end of their useful life. By 2035, all drayage trucks must be zero-emission.
- High priority and federal fleets must comply with the Model Year Schedule or elect to use the optional ZEV Milestone Schedule to phase in zero-emission vehicles to their fleet:
- Model Year Schedule: Fleets must only purchase zero-emission vehicles beginning 2024 and must remove internal combustion engine vehicles at the end of their useful life.
- ZEV Milestone Schedule (Optional): Instead of the Model Year Schedule, fleets may elect to meet zero-emission vehicle targets as a percentage of the total fleet starting with vehicle types that are most suitable for electrification.
At the same time as these new regulations are emerging, existing regulatory requirements affecting these vehicles are being implemented. If all of this sounds complicated, that’s because it is. CARB is trying to spread awareness through training and fact sheets, but with timelines rapidly approaching you may need extra help to assess the specific requirements for your fleet.
