“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!”

Not sure if you need a test?

If your diesel vehicle is over 14,000 GVWR and operates in California, the answer is likely YES. Ignoring this leads to DMV registration blocks. We handle the CTC testing paperwork and upload your results to CARB instantly.

Want to Pass on the First Try? Do These 4 Things.

Don’t waste money on a re-test. Follow this simple checklist before we arrive to ensure your truck is ready for certification.

1. Registered & Fee Paid

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.

2. Look for Visible Smoke

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.

3. Warm Up the Engine

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.

4. Locate the Engine Tag

We need to photograph your VIN & Engine Family Name (ECL label). Are these labels readable? (Commonly found on the valve cover or door jamb).

We've got you!
