Let Green Check be your go to service provider for the California regulated Clean Truck Check program. We will come to your location and perform the tests when the units are available and send the results straight to CARB.

OBD testing is twice a year and Green Check can add you to our tracking software so you never miss a test.

OBD testing applies to all diesel commercial trucks and RV’s that are 2013 engine year and newer with a GVW rating over 14,000lbs.

For units with engine years older than 2013 Green Check can perform the SAE J1667 Opacity test with visual inspection.
