Stay Compliant with CARB’s Clean Truck Check

If you're operating diesel trucks from 2013 or older, with 2012 or older engines, your vehicles are required to pass:

  • ✅ A Smoke Opacity Test (SAE J1667 / CARB-1667)

  • ✅ A Visual Inspection of emissions equipment

Avoid the shop downtime. Skip the risk of non-compliance.
We make it easy, mobile, and done right.

  • DMV registration holds

  • Loss of operating time and revenue

Don’t wait for enforcement. Take action now — and keep your fleet running.
