Protecting Your Fleet’s Performance and Compliance through the Clean Truck Check Program
The Clean Truck Check (formerly HD I/M) is a mandatory California Air Resources Board (CARB) program designed to ensure that heavy-duty diesel vehicles (GVWR > 14,000 lbs) operate with peak emissions efficiency. By maintaining these standards, you ensure your vehicle stays fuel-efficient, reduces its environmental footprint, and remains fully authorized to operate on California roadways.
To keep your business running smoothly and avoid operational delays, the program requires:
-
Accurate Reporting: Registering your vehicle in the CTC-VIS database.
-
Annual Compliance: Paying the required CARB compliance fee.
-
Certified Testing: Submitting periodic passing emissions tests conducted by a credentialed expert.
NB:// Failure to comply can lead to DMV registration holds and significant fines. Whether your truck is registered in California or out-of-state, if you operate on California public roads, you must meet these standards.

FAQs About Clean Truck Check
What is the Clean Truck Check (HD I/M) and does it apply to me?
The Clean Truck Check is a mandatory California Air Resources Board (CARB) program to ensure heavy-duty vehicles meet emissions standards. It applies to nearly all diesel and alternative fuel vehicles with a GVWR over 14,000 lbs operating in California. This includes vehicles registered out-of-state, public vehicles, motorhomes (CA registered), and commercial fleets. If you drive on California public roads, you likely need to comply.
How often do I need to get an emissions test for my truck?
As of October 2024, most vehicles require testing twice per year. However, starting in October 2027, vehicles equipped with On-Board Diagnostics (OBD) will transition to a quarterly (4 times per year) testing schedule. Agricultural vehicles and non-commercial motorhomes generally remain on an annual testing schedule. Always check your CTC-VIS account for your specific deadlines to avoid DMV registration holds.
Can DOT Mobile Inspection Services perform my Clean Truck Check?
Yes! To be valid, your test must be performed by a CARB-credentialed tester using a certified device. Our inspectors are fully credentialed by CARB and use approved testing equipment. The best part is that we are a mobile service—we come to your yard, home, or job site in Bakersfield and surrounding areas, saving you the time and fuel of driving to a testing station.
What happens if my vehicle fails the emissions test?
If your vehicle does not pass, it must be repaired and retested until it passes to remain compliant. Common reasons for failure include a “Check Engine” light being on or incomplete OBD monitors. Because we are an inspection-only company, we provide an unbiased, honest test. We don’t perform repairs, so you can trust that we aren’t “looking” for problems just to sell you parts.
How do I prove my compliance to the DMV or CARB?
Once we complete your test, the results are submitted to CARB via the CTC-VIS system. You must also ensure you have reported your vehicle in the system and paid your annual compliance fee. Once all requirements are met, you can download your Certificate of Compliance from your account. Note: It can take 1-3 business days for the system to update with the DMV, so don’t wait until the last minute!
Our mobile DOT inspection services are performed by a qualified inspector in full compliance with the safety standards established by the Federal Motor Carrier Safety Administration (FMCSA).
