UCR stands for Unified Carrier Registration. It is a federally mandated program that requires all motor carriers, brokers, freight forwarders, and leasing companies operating in interstate commerce to register and pay an annual fee based on the size of their fleet. The program was created to simplify and unify the previous multi-state registration requirements into a single system. It applies to carriers who operate commercial vehicles across state lines, including South Dakota.
