It is a document issued by the Federal Highway Administration (FHWA) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed, and used. These specifications include the shapes, colors, and fonts used in road markings and signs. In the United States, all traffic control devices must legally conform to these standards.
