The California Air Resources Board (CARB), California Bureau of Automotive Repair, and relevant state agencies must develop and implement a pilot Heavy-Duty Inspection and Maintenance Program for heavy-duty diesel trucks. CARB must establish test procedures for vehicle emissions control technologies. Additional terms and conditions apply. Zero-emission vehicles are exempt from program requirements.
