California Clean Truck Check Program
Clean Truck Check (CTC) is part of California's effort to reduce harmful emissions from heavy-duty diesel trucks. Understand how CTC fits with CARB 5-day permits and full compliance requirements.
Overview
What Is Clean Truck Check?
California's Clean Truck Check program requires periodic emissions testing and compliance verification for heavy-duty diesel vehicles operating in the state. The program helps ensure trucks meet current emissions standards and reduces nitrogen oxides and particulate matter pollution.
Many commercial heavy-duty diesel trucks operating in California must meet CARB rules. Requirements depend on engine year, mileage, equipment type, and program enrollment — not only where you are plated.
- Applies to qualifying heavy-duty diesel trucks in California
- Separate from but related to CARB permit requirements
- Reefers and older engines may need additional credentials
- 5-day pass does not replace every CARB program
Can you enter California urgently without Clean Truck Check? Yes — if your truck is not fully CARB-compliant, a one-time 5-day permit may allow legal operation for rare or urgent trips.

Engine Requirements
2010+ Engines and California Entry
To legally drive a heavy-duty truck in California, the vehicle should have an engine from 2010 or newer. This ensures the truck meets current emissions rules and helps reduce harmful pollutants. Vehicles that do not meet these standards may qualify for a one-time 5-day permit if they meet the separate eligibility criteria.
