For the first time in a convenient, searchable e-book format, ARTBA is providing the “Manual on Uniform Traffic Control Devices” (MUTCD). Last issued in 2009, but containing updates through 2012, the MUTCD is a comprehensive document issued by FHWA and contains standards by which traffic signs, road surface markings, and signals are designed, installed, and operated. These specifications include the shapes, colors, and fonts used in road markings and signs. All U.S. traffic control devices must generally conform to these standards. The manual is an essential tool for state and local agencies as well as private construction firms to ensure that the traffic control devices they use conform to the national standards. While some state agencies have developed their own sets of standards, including their own MUTCDs, these must substantially conform to the federal MUTCD.
