How Clean Truck Check Testing Works
1. What vehicles are required to complete Clean Truck Check (HD I/M) testing?
Most diesel and alternative-fuel trucks, buses, and heavy-duty vehicles operating in California must undergo regular Clean Truck Check emissions testing. This includes both in-state and out-of-state vehicles.
2. How often do I need to test my truck?
Most vehicles are required to test twice per year, although some may have different schedules depending on CARB requirements. We can check your vehicle and let you know your exact testing frequency.
3. Do you provide mobile, on-site testing?
Yes. We come directly to your fleet yard, jobsite, business location, or home, making the process faster and more convenient. No need to drive to a testing station.
4. How long does the Clean Truck Check test take?
Most tests take 10–20 minutes per vehicle, depending on your engine type and accessibility.
5. What do I need to have ready before testing?
You only need:
The truck on-site and accessible
Keys available
Engine OFF (we perform the test cold)
VIN plate or sticker visible
We handle the rest.
6. Does Clean Truck Check cause downtime for my fleet?
Not at all. Since we are fully mobile, your trucks remain on-site and available. We test one vehicle at a time, minimizing disruption.
We handle the rest.
7. Do you submit results to CARB?
Yes. We handle digital results submission immediately after your test. You’ll also receive a copy for your records.
We handle the rest.

A detailed diagnostic report
The reason for failure
Recommendations for fix and retest
We also provide scheduling for retesting once repairs are completed.
We handle the rest.
