The Clean Truck Check is required by the California Air Resource Board (CARB) on most diesel, alternate fuel, and hybrid vehicles with Gross Vehicle Weight Rating (GVWR) over 14000 pounds operating on public roads.

It ensures that heavy duty fleet vehicles remain safe even when carrying a heavy load.

James worked toward having his own smog station for years, and in 2011 he founded California Star Smog.

Smogging is a three part test that usually takes around 20 minutes:

Make sure your check-engine light is off. If your vehicle has been serviced or your battery has been disconnected recently, drive long enough (usually around 50 miles) for the onboard computer to confirm no repairs are needed.

Change your oil and air filter regularly. If your exhaust is consistently discolored, or if there are obvious parts damaged/missing from your vehicle, it may not pass visual inspection.

We will chemically test your exhaust to make sure it isn't producing too many hazardous pollutants.

If your vehicle passes, we will submit the report to the DMV so you can register your vehicle. If it doesn't pass, we'll point you in the right direction.
