Clean Truck Check Registration, Testing & DMV Compliance — All in One Place

From registering your vehicles in the Clean Truck Check system to performing required emissions tests and submitting documentation—we handle it all so you don’t have to.

Why Businesses Trust Central Valley Mobile Smog Test

What We Offer for CARB Compliance

Clean Truck Check Registration, VIN Verification & Reporting

We register your heavy-duty vehicles (14,000+ GVWR) into CARB’s CTC-VIS database, manage all required fleet information, and ensure your $30/vehicle annual compliance fee is paid—including back fees from 2023 and 2024 if needed.

If your vehicle is newly registered in California or has discrepancies in its documents, we also perform VIN Verification to confirm all records match DMV and CARB requirements—helping you avoid rejections or delays in compliance.

Emissions Testing for Clean Truck Check (HD I/M)

Our CARB-credentialed mobile team conducts required OBD emissions tests at your location. We follow compliance timelines—annual for motorhomes, semiannual for trucks and fleets—and ensure tests are completed within the 90-day window before each deadline.

Proof of Compliance Submission

Once testing is complete, we handle the electronic submission of results directly to CARB so your vehicle remains legal and off enforcement radar.

Notice to Submit to Testing (NST) Response

If you’ve been flagged by roadside monitors or received an NST letter from CARB, we’ll help you comply fast—avoiding violations, citations, or penalties.

DMV Registration Hold Resolution

We troubleshoot and resolve DMV registration blocks caused by Clean Truck Check noncompliance. We’ll test, report, and guide you to get your vehicle back on the road.

Compliance Calendar Tracking

We track deadlines based on your DMV registration date and send you proactive reminders so you’re never late for required testing.

Support for Multi-Vehicle Fleets
