How to Check Your Vehicle's Compliance Status
The California Air Resources Board (CARB) provides a public database to verify if a heavy-duty vehicle is compliant with the Clean Truck Check (HD I/M) program.
Step 1: Have your Vehicle Identification Number (VIN) ready.
Step 2: Click the button below to open the official CARB Vehicle Compliance Status Lookup tool.
Step 3: Enter your VIN and complete the security captcha.
Understanding Your Results:
🔴 Result: "Not Compliant" or "Testing Past Due" If your vehicle shows as non-compliant, you are at risk of a DMV registration hold or citation. You need an emissions test immediately. The Solution: Don't panic. As a credentialed mobile HD I/M tester, we can come to your location today, run the OBD or Opacity test, and upload your passing results to CARB immediately to clear your status.
🟢 Result: "Compliant" You are good to go for now! However, remember that testing is required periodically (up to twice a year for most vehicles). Save our website for when your next compliance deadline approaches.
🟡 Result: "VIN Not Found" If your 14,000+ lb diesel vehicle is not in the system, you may need to register it in the CTC-VIS database first. We can help guide you through the initial reporting process.
