Never Think About CARB Compliance Again

Fleet Clean Truck Check & Diesel Smog Testing Across Napa & Sonoma

I track which of your trucks are due, come test them where they sit, and file the results for you.

You run the fleet. I'll run the compliance calendar.

The Compliance Burden, Off Your Plate

Managing Clean Truck Check across a fleet is not one task — it's a rolling calendar. Different trucks, different deadlines, OBD versus opacity, CTC-VIS submissions, and a registration hold waiting for anything that slips.

Most fleet and operations managers are handling that on top of dispatch, maintenance, drivers, and everything else. It's the kind of thing that stays quiet until it's suddenly urgent.

So I take it. I keep a record of every truck I test for you and what its next deadline is. When a truck comes due, you hear from me first — not from the DMV. I show up where your trucks are parked, test them in 15 to 20 minutes each, submit the results directly to CTC-VIS, and confirm when it's filed.

No trucks leaving the yard. No drivers sitting in a queue. No spreadsheet you have to keep alive.
