California is known for its progressive environmental policies, and the state’s latest move to improve air quality is no exception. The California Air Resources Board (CARB) Clean Truck Check program mandates that trucks operating within the state comply with stringent emission standards. This initiative aims to reduce greenhouse gas emissions and smog-forming pollutants, ensuring cleaner air for all Californians. If you’re a truck owner or operator, understanding these requirements is crucial to staying compliant and avoiding fines. Here’s what you need to know about the CARB Clean Truck Check certification.
What is the CARB Clean Truck Check Program?
The CARB Clean Truck Check, also known as the Heavy-Duty Inspection and Maintenance (HD I/M) Program, is designed to monitor and enforce emission standards for heavy-duty trucks and buses. The program requires regular emissions testing and certification to ensure vehicles meet California’s strict air quality regulations.
Who Needs to Comply?
All heavy-duty vehicles over 14,000 pounds, including:
- Diesel trucks
