Heavy-Duty Inspection and Maintenance Program
CARB is exploring the development of a program to ensure that emissions control systems on heavy-duty vehicles are properly functioning throughout their entire operating life. A Heavy-Duty Vehicle Inspection and Maintenance (HD I/M) program would ensure that emissions from heavy-duty vehicles operating in California rarely exceed the NOx and PM emissions levels established by CARB.
