California’s ban on big rigs and buses made before 2010 goes into effect TODAY January 1st, 2023

SACRAMENTO, Calif. —Large trucks and buses made before 2010 will be prohibited from operating on California roadways starting Jan. 1. It’s the final rule in a set of clean air regulations the California Air Resources Board passed nearly 15 years ago.

The rule applies to diesel vehicles that weigh at least 14,000 pounds. The air resources board said there are an estimated 200,000 vehicles that have yet to comply with the rule just days before the new year, including roughly 70,000 big rig trucks, or about 10% of the commercial motor vehicles operating in the state, according to trucking lobbying groups.
