Transport Refrigeration Units (TRUs) are refrigeration systems powered by diesel internal combustion engines designed to refrigerate or heat perishable products that are transported in various containers, including semi-trailers, truck vans, shipping containers, and rail cars. Although TRU engines are relatively small, ranging from 9 to 36 horsepower, significant numbers of these engines congregate at distribution centers, truck stops, and other facilities, resulting in the potential for health risks to those that live and work nearby.
The Regulation applies to:
If your TRUs are based in California, you are required to register your TRU with the California Air Resources Board. The deadline for registration of existing units was July 31, 2009.
New units must be registered within 30 days of the unit coming into the control of the owner. You are strongly encouraged to apply for California Air Resources Board Identification Numbers (IDN) electronically, on the Internet, using the Air Resources Board's Equipment Registration (ARBER) system, since this is the fastest way to register. If you are the owner of a TRU that is based outside of California, applying for an IDN is voluntary and there is no deadline.

The public may use the following links to search CARB’s Equipment Registration (ARBER) system to check the compliance status of TRUs and TRU generator sets and provide comments or provide tips on violations about specific TRUs. CARB will monitor these comments/tips and follow up with enforcement action, if warranted.
You can also report noncompliant TRUs to CARB's Complaint Program.
