Heavy-Duty Inspection and Maintenance Program

Senate Bill (SB) 210 (Leyva; Chapter 298, Statutes of 2019) was signed into law by Governor Newsom on September 20, 2019, and directs CARB to develop and implement a comprehensive heavy-duty vehicle inspection and maintenance (HD I/M) program in consultation with the Department of Motor Vehicles and the Bureau of Automotive Repair. The full text of SB 210 is available from the California Legislative Information website. CARB is now undertaking efforts to develop a HD I/M program to ensure that emissions control systems on heavy-duty vehicles are properly functioning and remain low-emitting throughout their entire operating life.
