CARB’s Phase 2 Compliance Requirements Are Now in Effect: What Los Angeles Commercial Vehicle Operators Need to Know
California’s commercial vehicle operators are facing a critical juncture in emissions compliance as all compliance deadlines on or after January 1, 2025 will require the submission of a passing emissions compliance test as part of the vehicle’s compliance demonstration. The California Air Resources Board (CARB) has implemented stringent new requirements under both the Truck and Bus Regulation and the Clean Truck Check program, creating a complex landscape of deadlines and testing requirements that Los Angeles fleet operators must navigate carefully.
Understanding CARB’s Current Compliance Framework
The Regulation applies to nearly all diesel-fueled trucks, buses, and school buses with a gross vehicle weight rating (GVWR) greater than 14,000 pounds. For Los Angeles commercial operators, this means virtually every heavy-duty vehicle in their fleet must meet current compliance standards. As of January 1, 2023, all diesel-powered vehicles operating in California, with a gross vehicle weight rating over 14,000 lbs. must have a 2010 or newer engine and emission system with few exceptions.
The enforcement mechanism has become increasingly automated and strict. As of 2020, the California Department of Motor Vehicles (DMV) ensures the compliance of vehicles subject to the California Air Resources Board’s (CARB) Truck and Bus Regulation prior to DMV registration. This means non-compliant vehicles simply cannot be registered, creating immediate operational challenges for fleet operators.
Clean Truck Check: The New Testing Reality
The Clean Truck Check program represents a significant expansion of CARB’s enforcement capabilities. Senate Bill 210 directed CARB to develop and implement a comprehensive heavy-duty vehicle inspection and maintenance (HD I/M) regulation to ensure that vehicles’ emissions control systems are properly functioning when traveling on California’s roadways. The Board approved the regulation on December 9, 2021, with implementation to be phased in starting January 2023. Dubbed the Clean Truck Check, the program combines periodic vehicle testing requirements with other emissions monitoring techniques and expanded enforcement strategies.
For Los Angeles operators, the testing requirements are now fully active. Emissions compliance testing requirements are effective October 1, 2024. All compliance deadlines on or after January 1, 2025 will require the submission of a passing emissions compliance test as part of the vehicle’s compliance demonstration. The testing must be performed by CARB-credentialed testers, and passing tests may be submitted by the tester up to 90 days prior to the vehicle’s compliance deadline to allow time for any necessary repairs.
Financial Implications and Penalties
The financial stakes for compliance are substantial. The compliance fee for 2025 will be $31.18, representing an increase from the previous year. However, the real financial risk comes from non-compliance penalties. Fleets that don’t comply with the CARB state requirements face fines of up to $10,000 per vehicle per day, and out-of-state trucks may be restricted from operating in California.
For operators facing compliance challenges, limited options remain. If your vehicle is not compliant, you must pay your DMV registration fee to receive a 90-day Temporary Operating Permit (TOP) that will become active on the day your current vehicle registration expires. However, while you can drive during this period, the vehicle is still not compliant with CARB’s Truck & Bus Regulation and you could still be cited. The TOP is not a compliance extension; CARB considers a TOP permit your final opportunity to either demonstrate or achieve compliance.
Specific Requirements for Los Angeles Operators
Los Angeles commercial vehicle operators must understand that compliance involves multiple components. Nearly all diesel and alternative fuel heavy-duty trucks, buses, and other vehicles with a gross vehicle weight rating over 14,000 pounds that operate in California are subject to the compliance deadlines. Affected vehicles include hybrid trucks and buses, commercial vehicles, privately-owned vehicles, government vehicles, and vehicles registered outside of California.
The testing requirements vary based on vehicle age and equipment. OBD-equipped vehicles (2013 and newer diesel engines and 2018 and newer alternative fuel engines) are required to undergo a scan of the engine’s OBD data using a California Air Resources Board (CARB) certified OBD testing device. This creates different compliance pathways for different segments of a fleet.
Enforcement and Monitoring
CARB’s enforcement capabilities have expanded significantly with new technology. Clean Truck Check began in January 2023 with the use of roadside emissions monitoring devices (REMD) to screen for vehicles that may have high emissions. Vehicles flagged as potential high emitters will receive a Notice to Submit to Testing (NST) from California Air Resources Board (CARB) enforcement. When operators receive an NST, you will have 30 calendar days to submit to CARB a passing emissions compliance test performed by a credentialed tester.
Getting Professional Compliance Assistance
Given the complexity and high stakes of CARB compliance, Los Angeles commercial vehicle operators should work with experienced emissions testing and compliance services. Professional CARB Compliance Los Angeles services can help navigate the testing requirements, ensure proper documentation, and maintain fleet compliance on an ongoing basis.
The regulatory landscape will only become more demanding over time. Starting in 2025, these vehicles will have semiannual compliance deadlines (two each year, one every six months). In three years, this testing requirement will jump to four times a year. This escalating schedule means that establishing reliable compliance procedures now is essential for long-term operational success.
Looking Forward
Los Angeles commercial vehicle operators must recognize that CARB compliance is not a one-time hurdle but an ongoing operational requirement. The Truck and Bus Regulation is California law. CARB’s staff, management, executive officers, and board members are all bound by the requirements of the regulation and do not have the authority to offer any additional extensions or exceptions not already provided for in the law.
The message from CARB is clear: compliance is mandatory, enforcement is automated, and the penalties for non-compliance are severe. Los Angeles operators who proactively address these requirements through proper testing, documentation, and professional compliance assistance will be best positioned to maintain their operations while avoiding costly penalties and registration blocks.
For commercial vehicle operators in Los Angeles, the time for preparation has passed – the time for compliance is now. Working with qualified emissions testing services and staying informed about evolving requirements will be essential for continued success in California’s increasingly regulated commercial transportation environment.
