About Clean Truck Check
California’s program for heavy-duty truck and bus emissions compliance. Rules and deadlines are set by CARB—we help you meet them at the testing lane.
The Clean Truck Check program (part of CARB’s heavy-duty inspection & maintenance framework) applies to many diesel and alternative-fuel vehicles over 14,000 lb GVWR operating in California. Testing type and frequency depend on vehicle category and CARB phase-in schedules—always confirm current requirements on CARB’s official vehicle-owner page.
