It’s that time of year again, time to start getting ready for upcoming CARB (California Air Resources Board) Regulations deadlines. There are three important deadlines for drivers of commercial vehicles to be aware of: the TRU deadline at the end of the December, and two Truck and Bus deadlines, one at the beginning of January and one at the end. Below, a review of each of these regulations along with the important deadlines for carriers to mark in their calendars.

TRU Regulation:

The TRU (Transportation Refrigeration Unit) (or, “reefer”) regulation applies to in-use diesel fueled TRUs and TRU generator sets that operate in California, whether they are registered in or outside the state. It requires all TRUs and TRU generator sets that operate within the state to meet in-use performance standards by the end of the 7th year after the engine model year or the unit manufacture year. Any California-based refrigeration units are required to register with CARB within 30 days of obtaining a new unit. In addition, California terminal operators that operate TRUs are also required to provide updates to ARBER (Air Resources Board Equipment Registration) within 30 days of changes to any information within their Operator Reports.
