How does the California Clean Truck Check affect your fleet?

The California Clean Truck Check requires that any fleet that operates heavy-duty trucks in the state must periodically test applicable vehicles for emissions and report the data to the California Air Resources Board (CARB). This includes trucks based in California and out-of-state trucks in California. 

Fleets that don’t comply with the Clean Truck Check requirements face fines up to $10,000 per vehicle per day and out-of-state trucks may be prevented from operating in California. Obviously, it’s crucial for fleets across the country (and in Mexico and Canada) to understand this program.

Geotab’s CARB-compliant GO9 family of devices can automatically collect the required emissions data from vehicles and submit it to CARB, eliminating manual emissions testing and maximizing vehicle uptime.

What is the CARB Clean Truck Check program?

The Clean Truck Check is an emissions testing and reporting program for heavy-duty, non-gasoline vehicles with a gross vehicle weight rating (GVWR) of over 14,000 pounds that operate in California. This includes trucks, buses, agricultural equipment and public vehicles (federal, state and local government). Also known as the Heavy-Duty Inspection and Maintenance (HD I/M) Program, the program requires fleet owners to test their trucks’ greenhouse gas emissions on a regular basis and submit their results to CARB. 

The Clean Truck Check aims to help fleets identify high-emitting trucks so they can repair malfunctioning vehicle systems and reduce their emissions. Although heavy-duty vehicles only make up 3% of the vehicles on the state’s roads, they are responsible for over half of the smog-causing pollution and fine particulate matter from vehicles. 

CARB estimates that the new program will prevent 7,500 air-quality related deaths as well as 6,000 hospitalizations and emergency room visits from 2023 to 2050. It should also deliver $75 billion in health benefits – over 18 times the estimated $4 billion cost of the program.

What does the Clean Truck Check mean for your fleet?

Starting January 1, 2025, fleets that operate in California have new legal obligations under the Clean Truck Check program. Broadly speaking, fleets have to incorporate regular emissions testing and data submission into their compliance or maintenance schedules and consider how they want to comply with the requirements.

There are four methods for fleets to collect and submit their emissions-related data to remain in compliance:

• Use of a certified testing facility: These facilities are operated by approved independent contractors and require fleets to send their vehicles in for regular testing.
• Utilize a Portable Emission Acquisition System (PEAQS): These roadside systems collect a snapshot of emissions data from your fleet vehicle.
• Utilize in-house non-continuously-connected OBD scan tools: This requires a trained employee in-house to manually collect emissions data from your fleet vehicles.
• Employ a telematics device to collect and transmit data continuously: By utilizing a telematics device, fleets can collect and upload emissions data without interfering with vehicle uptime.

There are also administrative requirements that fleets must complete before they conduct their vehicle emissions tests, including registering vehicles with CARB, paying the annual Clean Truck Check vehicle fee, getting truck certificates, and generally ensuring vehicles are in good repair in preparation for testing.

What steps do fleets need to take to meet the Clean Truck Check requirements?

All fleets operating heavy-duty trucks in California (no matter where they are based) should take these steps:

1. Identify which vehicles within your fleet must be compliant with the Clean Truck Check Program.
2. Register for email alerts with the CARB regulatory board.
3. Determine when your vehicles’ compliance deadlines are (it’s based on DMV registration expiry dates). 
4. Register fleet vehicles and pay the $30 compliance fee for each vehicle. 
5. Complete emissions tests on applicable vehicles using one of the four methods described above: certified testing facility, PEAQS, non-continuously-connected OBD scan tools or a continuously connected telematics device. If using a telematics device, check with your provider to ensure they are CARB-compliant.
6. Submit test results to CARB within 90 days of applicable deadlines. After successfully completing tests, vehicles will receive a certificate of compliance and can operate in the state of California.
7. Train drivers on requirements, including, keeping certificates handy in applicable vehicles to ensure access to freight facilities.
8. If using a T-harness to connect a telematics device, ensure it meets CARB’s aftermarket parts regulations. Geotab is the only telematics provider with a CARB installation exemption for a T-harness in California.

How Geotab’s automated Clean Truck Check program solution helps fleets comply and keeps vehicles on the road

Geotab's CARB-certified Clean Truck Check solution enables fleets operating in and driving through California to seamlessly comply with the state's environmental regulations using one of the few continuously connected solutions that support both the J1939 and J1979 protocols and offers all installation options (including using a T-harness) for continuous emissions data collection.

With Geotab's telematics solution, including our exclusive Emissions Diagnostics Report, fleets get:

• Effortless Reporting: Automatically create and submit CARB-compliant emissions reports for seamless compliance and know when reporting deadlines are approaching. 
• Continuous Connectivity: Ensure seamless and continuous data transmission. It's the only aftermarket solution granted an exemption by CARB from the anti-tampering provisions of the California Vehicle Code, allowing the device to stay connected while keeping the OBD port free for other uses.
• Streamlined Operations: No need to remove vehicles from duty cycles for manual testing or manage fleet needs on separate platforms.
• Maintenance Insight: Know when trucks have passed or failed testing and need maintenance to comply.
• Future-Proof Compliance: Stay ahead of increasing testing requirements and potential adoption of similar regulations in other states.

The MyGeotab platform can also help fleets reduce costs by identifying and reducing idling, optimizing routes, proactively managing maintenance and much more.

Conclusion — Streamline your CARB compliance and reduce the risk of penalties

Starting January 1, 2025, the CARB Clean Truck Check program requires heavy-duty vehicles operating in California to undergo semi-annual emissions testing and reporting. Non-compliance can result in significant financial penalties, including fines of up to $10,000 per vehicle per day, and may even prevent out-of-state trucks in California from operating. To meet these requirements, fleets can utilize various methods, including certified testing facilities, portable emissions systems and telematics devices.

Geotab's comprehensive and CARB-compliant telematics solution offers a streamlined and efficient way to meet the Clean Truck Check requirements and maximize vehicle uptime. With a GO9 device, a certified T-harness and our exclusive Emissions Diagnostics Report, fleets across the U.S. can ensure they comply with the California Clean Truck Check, while also benefiting from improved efficiency and reduced costs.
