UNDERSTANDING CALIFORNIA'S CLEAN TRUCK CHECK PROGRAM


The Clean Truck Check (also known as the Heavy-Duty Inspection and Maintenance, or HD I/M, program) is a California Air Resources Board (CARB) regulation requiring periodic emissions testing for heavy-duty vehicles over 14,000 lbs GVWR operating anywhere on California roads — including out-of-state trucks. The goal is simple: catch malfunctioning emissions systems early and keep California's air cleaner.

WHO NEEDS TO COMPLY
  • Any diesel or heavy-duty vehicle over 14,000 lbs GVWR driving on CA public roads
  • Applies to California-registered and out-of-state fleets
  • Includes vehicles with SE plates and non-CA registered motorhomes
  • Enforced through roadside inspections at borders, ports, and railyards, plus DMV registration checks
TESTING REQUIREMENTS
  • Semi-annual testing (twice a year) required through 2026
  • Quarterly testing begins October 1, 2027 for OBD-equipped vehicles
  • Opacity-tested vehicles (2012 and older engines) stay on a semi-annual schedule
  • Testing methods include CARB-certified facilities, portable roadside testing, or connected telematics devices
  • Vehicle status is tracked as Compliant, Conditional, or Non-Compliant — visible to CARB and CHP

Non-compliance carries steep risk — fines up to $10,000 per vehicle, per day, and out-of-state trucks can be restricted from operating in California. Don't wait for a roadside stop to find out where you stand.

  • DO YOU SERVICE PASSENGER VEHICLES OR LIGHT-DUTY TRUCKS?

    No. We specialize exclusively in commercial and heavy-duty fleet diesel and alternative fuel vehicles that are "In-Scope" for the Clean Truck Check program. We do not service passenger vehicles.

  • WHAT'S THE DIFFERENCE BETWEEN AN OFFICIAL OBD TEST AND AN OBD PRE-TEST?

    An official OBD test is when a scan is submitted to CARB. CARB issues a pass/fail result based on the scan data submitted, then the results are uploaded to the clients CTC-VIS portal as an official compliance record.


    An OBD pre-test is localized testing using software that mimics the CARB system. This is purely a diagnostic scan used for internal troubleshooting and confirmation before an official test. Often times when clients suspect a mechanical problem impacting the emissions system on a vehicle, or after mechanical work has been performed, they will use a pre-test to verify problem codes are cleared before submitting an official OBD test. Proactively speaking, a failed test starts a timer in which repairs must be completed by a certain timeframe to remain compliant. A pre-test can help identify problems early allowing more time for repairs to be completed before a failure triggers CARB deadlines.

  • CAN I CHOOSE HOW INVOLVED I WANT TO BE IN THE COMPLIANCE PROCESS?

    Absolutely. Some fleets prefer our fully automated CaaS solution, while others choose our managed solution known as our Path to Green Partnership Program to stay more hands-on while still benefiting from the additional administrative support. Others use On-Demand testing to handed tests as they become due. Our team can flex to your preferred level of involvement.

  • WHAT IS THE P2G ACTIVATION AWARDS PROGRAM?

    It's our referral commission program. Anyone who refers P2G Emissions and Compliance Group can earn cash for every CaaS activation referred, plus bonus awards for every 5 activations—This is ideally for dealerships and partners looking to boost extra revenue while supporting fleet compliance using their existing networking contacts.

  • DO YOU ONLY SERVE FLEETS IN BAKERSFIELD, AND/OR CALIFORNIA?

    While we're proudly based in Bakersfield and rooted in Kern County, our reach really depends on the type of service.


    For manual testing such and on-demand testing and our managed solutions (Partnership Programs), our technicians need physical access to the vehicle. We currently travel anywhere throughout Bakersfield and surrounding areas within Kern County, even beyond when the economics make sense for the client.


    For clients opting for automation using our Compliance as a Service (CaaS) option, our connected-device technology allows us to support fleets anywhere in the United States and Canada. We simply program and configure the hardware, ship it to the client, and the client simply plugs the device into the vehicles OBD port using a direct connect or pass-through cable. From there, we can manage everything remotely.
