Yard, job site or driveway
Which test does your truck need?
It comes down to the engine’s model year. We run both tests, so you only need one call.
2013 and newer: OBD test
We connect to the truck’s diagnostic port and read the emissions data the engine already records. No smoke test needed.
2012 and older: OVI test
A smoke opacity test using the SAE J1667 snap acceleration procedure, plus a visual inspection of the emissions equipment.
Not sure which one applies? Call with the engine year and we’ll tell you.
Don’t want to deal with CARB’s website? We’ll handle it.
Along with your test, Danny can take care of the CARB account side of Clean Truck Check, so you don’t have to log in and figure out the system yourself.

Most trucks test twice a year. Newer diesel trucks move to four times a year starting October 2027.
DMV hold
