Mobile CARB/DMV Diesel Clean Truck Checks: Compliance for Semi-Trucks in Sacramento to Fresno Corridor
Navigating California's stringent emissions regulations can be challenging for semi-truck owners and fleet operators, especially with the California Air Resources Board (CARB) Clean Truck Check program. For those operating in the Sacramento to Fresno corridor, ensuring compliance is critical to avoid fines, registration holds, and operational disruptions. Our mobile CARB/DMV Diesel Clean Truck Check service offers a seamless, cost-effective solution tailored to the needs of semi-truck operators in this region, with no travel fees added to our rates. This blog provides a comprehensive guide to the Clean Truck Check requirements, our mobile testing services, and how we help keep your fleet compliant and road-ready.
Understanding CARB’s Clean Truck Check Program
The Clean Truck Check, formally known as the Heavy-Duty Inspection and Maintenance (HD I/M) Regulation, is a CARB initiative designed to reduce emissions from heavy-duty vehicles operating in California. Enacted under Senate Bill 210 (2019), the program targets diesel and alternative fuel vehicles with a gross vehicle weight rating (GVWR) over 14,000 pounds, including semi-trucks, regardless of whether they are registered in California. The goal is to ensure that emissions control systems are functioning properly, reducing smog-forming nitrogen oxides (NOx) and particulate matter (PM) that contribute to poor air quality.
Key Compliance Requirements
To comply with the Clean Truck Check, semi-truck owners must:
Register in the CTC-VIS Database: All affected vehicles must be reported in the Clean Truck Check Vehicle Inspection System (CTC-VIS) at cleantruckcheck.arb.ca.gov. This includes vehicle and owner information, such as the Vehicle Identification Number (VIN), make, model, and fuel type.
Pay the Annual Compliance Fee: As of 2025, the annual fee is $31.18 per vehicle, adjusted annually based on the California Consumer Price Index (CCPI). Payments must be made through CTC-VIS using credit/debit cards or eCheck, with processing times of 1-2 days for cards and up to 7 days for eChecks.
Complete Emissions Compliance Testing:
Vehicles with 2013 or Newer Engines: Require a visual inspection and an On-Board Diagnostics (OBD) test twice per year (increasing to quarterly testing starting January 2027 for OBD-equipped vehicles).
Vehicles with 2012 or Older Diesel Engines: Require a smoke opacity test and a visual inspection of emissions control equipment twice per year.
Alternative Fuel Vehicles (2017 or Older): Require only a visual inspection semi-annually.
Testing must be conducted by a CARB-credentialed tester using certified equipment, with results submitted to CARB within 90 days prior to the vehicle’s compliance deadline.
Maintain Compliance Certificates: After passing tests and paying fees, a compliance certificate is issued for each vehicle, accessible via CTC-VIS. While not required to be carried, keeping certificates handy is recommended for inspections or freight facility access.
Compliance Deadlines
California-Registered Vehicles: Deadlines align with DMV registration expiration dates, with semi-annual testing due on the expiration date and six months later (e.g., a January 1 registration expiration requires testing by January 1 and July 1).
Out-of-State and DMV-Exempt Vehicles: Deadlines are based on the last digit of the VIN, with specific months assigned (e.g., VIN ending in 2 has deadlines in June and December). Check your CTC-VIS account for exact dates.
2024 Testing: For 2024, only one test is required per vehicle, with deadlines between July 1 and December 31, 2024. Starting January 1, 2025, semi-annual testing is mandatory for most vehicles.
Non-Compliance Consequences
Failure to comply can result in:
DMV Registration Holds: Non-compliant vehicles face registration blocks, preventing renewal until compliance is met.
Fines: Penalties can reach up to $10,000 per vehicle per day for non-compliance.
Operational Restrictions: Non-compliant trucks may be restricted from operating in California, particularly at seaports and railyards.
