How Clean Truck Check Testing Works
1. Do you come to my home, jobsite, or parking spot?
Yes. All testing is mobile. We can test your truck wherever it is parked—home, yard, jobsite, or anywhere in San Diego County.
2. How long does the Clean Truck Check test take?
Most single-truck tests take 10–20 minutes, depending on engine type and accessibility.
3. What do I need to have ready before testing?
You only need:
-
The truck parked and accessible
-
Keys available
-
VIN plate visible
-
Engine OFF (we test cold)
We take care of everything else.
4. Do you test individual owner-operator trucks?
Yes. We specialize in single-truck and small operator testing. Fast and convenient.
5. Do you test out-of-state trucks that enter California?
Yes. Any truck operating in California—regardless of home state—must complete Clean Truck Check (HD I/M) testing. We test out-of-state trucks regularly.
6. How often do I need to complete Clean Truck Check testing?
Most trucks must test twice per year, though requirements vary.
We’ll confirm your exact CARB testing frequency.
7. Do you submit test results to CARB?
Yes. We electronically submit your results to CARB and provide you a digital copy for your records.
8. What happens if my truck fails the test?
You’ll receive a clear diagnostic report explaining the reason for failure.
After repairs, we can return for a retest.
9. Are you CARB-certified to perform HD I/M testing?
Yes. All testing is performed by a CARB Clean Truck Check–certified technician using approved equipment.
10. Do I need to bring anything for the test?
