“They were super helpful for getting me an opacity test needed for my registration. They charged me half of what another shop was trying to charge. They seemed super nice and honest and genuinely helped me a ton!”

A: To avoid a failed test (and a re-test fee), please check these 4 items before testing/we arrive:
A: Yes. If you drive into California, you must comply. The Clean Truck Check applies to all diesel and alternative fuel vehicles over 14,000 lbs GVWR operating on California roads, regardless of where the license plate is from. This applies to diesel RVs as well.
A: If your VIN is blocked in the CARB system (preventing you from legally entering CA), here is the fix:
Once uploaded, your compliance status typically updates within 24-48 hours, clearing you for travel.
A: Yes! We serve the Greater Portland and Vancouver areas. Our Mobile Service saves you the hassle of moving unregistered or non-compliant equipment. We come to your yard, perform the test, and upload the data so you are legal before you hit I-5.
(Travel charges apply based on time/distance).
A: The actual testing process is fast—typically 15 to 20 minutes per truck. For mobile visits, we just need a safe, flat area to park near the vehicle. Be sure your vehicle is also warmed up.
A: No. This is a California-specific requirement (Clean Truck Check / HD I/M). It is different from standard Oregon DEQ testing. We are credentialed specifically for the California CARB heavy-duty program, which is required to cross the border legally.
A: Yes! If you are planning a road trip south into CA, you need to be compliant. If your diesel pusher is over 14,000 lbs GVWR, we can get you certified so you don’t face enforcement issues at the California scales.
A: If it fails, the CARB block will remain. We will provide a report/explanation for why (usually a Check Engine Light, visible smoke, or high particulate matter). You will need to repair the issue and schedule a re-test.
Be sure your vehicle is registered with CARB. Also, make sure you’ve logged in to your CTC-VIS account, and the $31.18 annual compliance fee is paid.
If your truck is blowing smoke, do not schedule a test yet. It will fail. Have a mechanic fix the issue first to save yourself time & the cost of a failed test.
A cold engine can trigger a false failure. Please run the vehicle for at least 15 minutes before we arrive to clear moisture and get the catalyst hot.
We need to photograph your VIN & Engine Family Name (ECL label). Are these labels readable? (Commonly found on the valve cover or door jamb).
