Rowland Heights Clean Truck Check Testing
CARB Credentialed Heavy-Duty Testers in Rowland Heights, CA
Who needs this: nearly all diesel, alternative-fuel, and hybrid vehicles over 14,000 lbs GVWR operating in Rowland Heights or anywhere in California — including out-of-state registered trucks — must comply with CARB’s Clean Truck Check program. That means reporting the vehicle in CTC-VIS, paying the annual compliance fee (about $31/vehicle), and submitting passing emissions tests twice per year from a CARB credentialed tester. Deadlines follow your DMV registration expiration date, and tests can be submitted up to 90 days early. Miss a deadline and the DMV places a registration hold; fines run up to $10,000 per vehicle per day, and non-compliant trucks can be denied entry to ports and railyards. Starting October 1, 2027, OBD-equipped vehicles (2013+ diesel engines) move to four tests per year. Full details in our California Clean Truck Check guide.
CARB credentialed Clean Truck Check testers serving Rowland Heights are listed below — including mobile testers who come to your yard. Testers perform the OBD scan (2013+ diesel engines) or smoke opacity test (2012 and older) and submit passing results directly to CTC-VIS.
