Who Must Comply with CARB’s Clean Truck Check?
Most heavy-duty vehicles operating in California must register and comply with CARB’s Clean Truck Check program—even if they are registered outside the state.
Out-of-State Vehicles
Any truck over 14,000 lbs GVWR entering California must register in CTC-VIS and comply before operating in the state.
Agricultural & Motorhome Vehicles
Agricultural vehicles and motorhomes over 14,000 lbs GVWR are included but only require annual testing instead of semi-annual.
Clean Truck Check Requirements
The California Air Resources Board (CARB) requires heavy-duty vehicles over 14,000 lbs GVWR to meet specific testing and compliance rules. Here’s what every truck owner and fleet manager must know. Official details: ww2.arb.ca.gov.
Gross Vehicle Weight Rating (GVWR)
Applies to vehicles with a GVWR over 14,000 pounds, which includes the vehicle’s empty weight and maximum load capacity.
Engine Model Year
Clean Truck Check applies to all diesel and alternative-fuel vehicles over 14,000 lbs GVWR, regardless of engine model year. Even engines older than 2010 must pass emissions tests.
Testing Frequency
Semi-annual testing for most vehicles; annual testing for some agricultural vehicles and motorhomes. Starting October 2027, OBD-equipped vehicles (typically 2013+) transition to quarterly testing.
Emissions Standards
Vehicles must meet CARB thresholds for pollutants like particulate matter (PM) and nitrogen oxides (NOx) during testing.
Registration (CTC-VIS)
All vehicles must be registered in the Clean Truck Check Vehicle Inspection System (CTC-VIS). You’ll need the VIN, engine model year, and GVWR.
Annual Compliance Fee
CARB requires an annual compliance fee per vehicle (e.g. $32.13); this is included in our total service price of $80.00 per vehicle.
Simple, Transparent Pricing
$80.00 per vehicle includes the $32.13 CARB compliance fee and our third-party CTC-VIS reporting service. Additional vehicles in the same order are $70.00 each. Emissions testing is done at CARB-authorized facilities (separate from this fee).

Penalties for Non‑Compliance
Failing to meet testing requirements can result in fines, registration holds, and other enforcement actions. Ensure compliance to avoid disruptions to vehicle operations.
Clean Truck Check Exemptions
Not every vehicle must participate. These vehicles are generally exempt from Clean Truck Check requirements.
Zero-Emission Vehicles
Fully electric and hydrogen fuel cell vehicles are exempt.
Emergency Vehicles
Fire trucks, ambulances, police vehicles, and other authorized emergency response vehicles.
Military & Historic Vehicles
Tactical military equipment and registered historical vehicles are excluded.
Specialized Exemptions
Experimental engines or certified ultra-low NOx engines (0.01 g/bhp-hr) may qualify for exemption until 2027.
Testing Requirements with Credentialed Testers
The California Air Resources Board (CARB) requires emissions testing for certain vehicles to meet air quality standards. These requirements ensure vehicles comply with regulations aimed at reducing harmful emissions.
Vehicle Eligibility
Who Needs Testing?
Diesel and alternative-fuel vehicles with a Gross Vehicle Weight Rating (GVWR) over 14,000 pounds must undergo emissions testing as part of CARB's Clean Truck Check program.
Testing Frequency
Semi-Annual Testing
Most heavy-duty vehicles must complete emissions testing twice per year.
Annual Testing
Some vehicles, such as specific agricultural vehicles and California-registered motorhomes, may qualify for annual testing.
Quarterly Testing
Beginning October 2027, vehicles equipped with On-Board Diagnostics (OBD) systems will transition to quarterly emissions testing.
Testing Procedures
On-Board Diagnostics (OBD) Testing
For vehicles with OBD systems, emissions data is collected directly from the onboard computer to verify that emissions controls are functioning correctly.
Opacity Testing
For older vehicles without OBD systems, a smoke opacity test measures exhaust smoke density to evaluate particulate emissions.
Note: Emissions testing must be completed at CARB-authorized facilities. We are not CARB and do not perform testing; we provide third-party reporting assistance through CTC-VIS. For official program and testing locations, visit ww2.arb.ca.gov.
