The Interstate Commerce Commission (ICC) was a regulatory agency in the United States (created by the Interstate Commerce Act of 1887). The agency's original purpose was to regulate railroads. Later the trucking industry in the United States was added. The purpose was to ensure fair rates, to eliminate rate discrimination, and to regulate other aspects of common carriers. This included public transport bus service and telephone companies. Congress expanded ICC authority to regulate other modes of commerce beginning in 1906. The agency was abolished in 1995, and its remaining functions were transferred to the Surface Transportation Board.
