Vehicle Rules Are Confusing. We’ve Seen It All.

If you’ve tried to navigate CARB’s Clean Truck Check system for your farm equipment, you know the frustration: The system says one thing. The regulations say another. And your trucks sit idle.

Just this month, we worked with a construction/agricultural operation running a Gradall GW-506-41 excavator with a Volvo Tier 4 Final engine. CARB’s guidance suggested OVI testing was required. But when we went to enter it in CTC-VIS? The system would only accept OBD submissions.

This isn’t unusual. It’s the norm. You need a tester who has actually dealt with these edge cases—not someone reading from a script.
