Keeping California Compliant: Why NorCalCARBMobile.com Is the Go-To for On-Site Clean Truck Check Testing

If you operate a diesel-powered motorhome, box truck, day cab, sleeper, or manage a full fleet of commercial vehicles in California, you're now responsible for meeting new compliance standards under the CARB Clean Truck Check (CTC) program.

But here’s the good news: NorCal CARB Mobile takes the stress out of Clean Truck Check compliance by bringing the test to you — wherever you are in Northern California.

Let’s break down how we help keep your vehicles compliant, your business moving, and your registrations clear of DMV holds.

 

✅ What is the Clean Truck Check?

The California Air Resources Board (CARB) launched the Clean Truck Check (formerly HD I/M) to reduce diesel emissions from medium- and heavy-duty vehicles with a GVWR over 14,000 lbs.

This includes:

• Diesel trucks (commercial and personal use)

• Motorhomes over 14K lbs

• Box trucks

• Day cabs and long-haul sleepers

• Large work vans and RVs

Compliance requires two things:

1. Annual emissions testing (either OBD or opacity/visual)

2. Annual registration in the CTC-VIS portal, with a per-vehicle fee
