CARB TRU Registration & Compliance Inspection
ARBER Registration, Equipment Verification & California Reefer Compliance
Operating a refrigerated trailer, reefer truck or Transport Refrigeration Unit in California?
Danny’s Mobile Emissions provides CARB TRU registration, ARBER filing, equipment verification and compliance-support services for refrigerated transportation fleets operating in California.
Whether you operate a single refrigerated trailer or manage a large fleet of reefers, we can help verify your equipment information, register your TRUs in CARB's ARBER system and assist with ongoing California TRU compliance requirements.
California CARB Compliance for Refrigerated Trailers
Transport Refrigeration Units operating in California are regulated separately from the truck or tractor pulling the trailer.
While your tractor may fall under California's Clean Truck Check requirements, the refrigeration unit mounted on your refrigerated trailer may also be subject to California's Transport Refrigeration Unit (TRU) Regulation.
CARB uses the Air Resources Board Equipment Registration system — ARBER — to register TRUs and maintain equipment compliance information. arber.arb.ca.gov
Danny’s Mobile Emissions can help you manage both sides of your California fleet compliance.

What Is a CARB TRU?
A Transport Refrigeration Unit (TRU) is the refrigeration system used to control the temperature of products being transported in refrigerated trucks, trailers, shipping containers and similar transportation equipment.
Common examples include refrigeration units manufactured by companies such as Thermo King and Carrier.
TRUs operating in California are subject to CARB's TRU regulatory requirements regardless of whether the carrier itself is based in California.
CARB TRU Compliance Inspection
Before submitting or updating an ARBER registration, Danny’s Mobile Emissions can perform a TRU compliance inspection and equipment-verification review. We compare the physical information on the refrigeration equipment and trailer with the information required for CARB reporting.
This can help identify incorrect serial numbers, equipment information, engine information or existing ARBER records before they create registration or verification problems.
