Truck Compliance


The first step in complying with Advanced Clean Fleets and Clean Truck Check is to register your trucks in the databases below:

Advanced Clean Fleets: Drayage Requirements

UPDATE: On December 28, 2023, CARB issued an enforcement notice stating that they will not be enforcing the Advanced Clean Fleets Drayage reporting and recordkeeping requirements until an EPA waiver has been approved. The Port of Hueneme is still to advising trucks entering the port to continue to correctly register their trucks in TRUCRS.

Advanced Clean Fleets (ACF) regulation is a part of CARB’s strategy to accelerate the transition to zero-emissions medium-duty and heavy-duty vehicles. As of October 2023, the regulation is now in effect. This regulation will impact any in-use class 7 and 8 on-road vehicles that transport cargo to and from California seaports and intermodal railyards. According to the regulation all trucks that are either picking up or dropping off cargo at the Port of Hueneme, must register in CARB’s TRUCRS database as “Tractor-Drayage Sleeper Cab” or as “Tractor-Drayage Day Cab” in order to be compliant. Soon only zero-emission trucks will be allowed to register in TRUCRS.

Clean Truck Check

UPDATE: CARB is providing an initial grace period to fleets with respect to the freight facility requirements within the Clean Truck Check (CTC) program. As of 2/1/24, all vehicles subject to CTC will be considered compliant with respect to the freight facility requirements and the ports can allow vehicles to enter ports and railyards without verifying the vehicle for CTC compliance until July 1, 2024. Starting July 1, 2024, CARB will strengthen these requirements and incorporate a compliant CTC VIN list for ports to verify CTC compliance. In the coming months, CARB will continue to work with freight facilities to ensure a smooth transition into these more stringent requirements in July.

California DMV registration holds are automatically placed on vehicles that are not compliant with Clean Truck Check requirements. To avoid potential registration holds, report your vehicle in the Clean Truck Check reporting database (CTC-VIS) at and pay any compliance fees that are due for 2023 and/or 2024.

For TeleCheck (eCheck) payments, please allow 7 business days for processing before you can download your certificate. Once a registration hold is placed on a vehicle, it will take 3 - 5 business days from the date the certificate is downloaded for that to be updated with DMV. CARB staff recommends that you allow enough time for processing prior to any deadline .

If DMV has placed an SB 210 registration hold on your vehicle and you believe your vehicle is compliant with Clean Truck Check, please email for assistance.

TRU ATCM 2022 Amendments

UPDATE: On December 4, 2023, a California trial court prohibited CARB from collecting the fees included in the 2022 amendments to the Airborne Toxic Control Measure for In-Use Diesel-Fueled Transport Refrigeration Units (TRU) and TRU Generator Sets, and Facilities Where TRUs Operate (TRU ATCM) at this time.

CARB intends to proceed with implementation of all other requirements included in the 2022 amendments and begin issuance of TRU compliance labels in early 2024.

TRU owners or operators are not required to pay TRU operating fees at this time. CARB staff will issue two TRU compliance labels to each compliant unit reported in the ARBER database. TRU owners will not receive compliance labels by December 31, 2023. In the meantime, owners may print a copy of their ARBER certificate to show proof of compliance.

Enforcement at the Port of Hueneme

ACF, CTC, and the TRU ATCM 2022 amendments are requiring California seaports and intermodal railyards to comply with reporting and recordkeeping requirements. Thus the Port of Hueneme’s proposed technology plan is preparing to no longer allow non-compliant trucks and TRUs to enter and operate on Port starting January 1, 2024.
