Do you own, or do business with, diesel on-road trucks or buses with a gross vehicle weight rating of more than 14,000 pounds?
Beginning January 1, 2020, compliance with the California Air Resources Board’s (CARB) Truck and Bus Regulation will be automatically verified by the California Department of Motor Vehicles (DMV) as part of the vehicle registration process. Senate Bill 1, the Road Repair and Accountability Act of 2017 (SB 1), was signed into law on April 28, 2017. This bill states that DMV must check that vehicles are compliant with, or exempt from, CARB’s Truck and Bus Regulation. If a vehicle is not compliant with the rule, DMV can no longer register that vehicle.
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.
