Effective January 1, 2020, the California Air Resources Board’s (CARB) Truck and Bus Regulation compliance verification will be a part of the California Department of Motor Vehicles (DMV) vehicle registration process. The Truck & Bus Regulation requires that most medium- and heavy-duty commercial diesel trucks and buses with older engines be replaced or repowered with 2010 or newer model year engines through a phase-in schedule.

As stated in Senate Bill 1, the Road Repair and Accountability Act of 2017, the DMV must check that vehicles are compliant with, or exempt from, CARB’s Truck and Bus Regulation. The DMV will no longer register a vehicle out of compliance.
