Advanced Clean Fleets Reporting Update

The Truck Regulation Upload, Compliance and Reporting System is open

Fleet owners subject to California Air Resources Board’s (CARB’s) medium and heavy-duty vehicle regulations must report annually to meet regulatory requirements. The Truck Regulation Upload, Compliance, and Reporting System (TRUCRS) has been updated and is available for fleet owners to report and update company, vehicle, and engine information to meet Advanced Clean Fleets (ACF) reporting requirements.

TRUCRS is the official reporting system for fleets to meet reporting and compliance requirements for all the following regulations:

  • Advanced Clean Fleets Regulation
  • Truck and Bus Regulation
  • Zero-Emissions Airport Shuttle Regulation
  • Solid Waste Collection Vehicle Regulation

Reporting guidance, regulation language, advisories, fact sheets, and other compliance tools can be accessed through the Advanced Clean Fleets, Registration and Reporting webpage.

If you already have a TRUCRS account and cannot remember your login, do not create another account.

Please use the password recovery feature as creating a second account will automatically lock both accounts.

If you have created a second account or are locked out and don’t have access to the email used to create the original account, reach out to or call the Hotline at (866) 634-3735 for assistance.

Timely reporting is essential to avoid potential registration denial or delay when registering your vehicle with DMV.

To begin the reporting process, please visit the TRUCRS online reporting portal.

The Advanced Clean Fleets regulation was adopted by California Air Resources Board (CARB) at the April 28, 2023, Board Hearing, and was effective on October 1, 2023 (California Code of Regulations, Title 13, Sections 2013, 2013.1, 2013.2, 2013.3, 2013.4, 2014,2014.1, 2014.2, 2014.3, 2015, 2015.1, 2015.2, 2015.3, 2015.4, 2015.5, 2015.6, and 2016). The ACF regulation complements CARB’s recently adopted Advanced Clean Trucks regulation and will help advance the introduction of zero-emission technologies into California’s truck and bus fleets requiring fleets that are well suited for electrification to transition to zero-emission vehicles (ZEV) through requirements to both phase-in the use of ZEVs for targeted fleets and requirements that manufacturers only manufacture ZEV trucks starting in the 2036 model year. The ACF regulation is expected to introduce 1,690,000 ZEVs into the California fleet by 2050. Additionally, the ACF regulation is expected to result in $26.5 billion in statewide health benefits from improved air quality and save fleet owners an estimated $48.0 billion through 2050.

The ACF Regulation is part of a comprehensive strategy to achieve a zero-emission truck and bus fleet by 2045 everywhere feasible and significantly earlier for market segments such as last mile delivery, public fleets, and drayage applications. Achieving California’s long-term air quality, climate, and public health goals will require a transition from the conventional combustion technologies to zero-emission everywhere feasible and near-zero-emission powered by clean, low-carbon renewable fuels everywhere else. Promoting the development and use of zero-emission trucks will contribute to the goals set by the Governor’s Executive Order N-79-20 and the Sustainable Freight Action Plan, and will help achieve emission reductions as outlined in the State Implementation Plan, Senate Bill (SB) 350 (de León, Chapter 547, Statutes of 2015), Assembly Bill (AB) 32 (Nuñez, Chapter 488, Statutes of 2006), and SB 32 (Pavley, Chapter 249, Statutes of 2016), and AB 1279 (Muratsuchi, Chapter 337, Statutes of 2022). This effort is part of a broader strategy to increase clean, affordable transportation options such as zero-emission technologies, innovative methods to improve freight activity, and efficiency of transportation systems in California.
