A Clean Truck Check, or Heavy-Duty Vehicle Inspection and Maintenance (HD I/M) regulation, is a California program designed to ensure that heavy-duty vehicles operating in the state have properly functioning emissions control systems. It involves periodic emissions testing, roadside monitoring, and data reporting to verify compliance.
To become Clean Truck Check compliant, the general requirement is to have your vehicle tested by a credential tester and submit a passing emissions compliance test.
It focuses on heavy-duty vehicles (GVWR over 14,000 lbs) that operate on California public roads, regardless of their registration state.
A Clean Air CARB Certificate, in this context, refers to the certification or compliance with regulations established by the California Air Resources Board (CARB) for various products and vehicles, primarily to ensure they meet emissions standards and other environmental requirements.
