What is the MUTCD?

The Federal Highway Administration (FHWA) is an agency within the U.S. Department of Transportation that supports State and local governments in the design, construction, and maintenance of the Nation’s highway system. The FHWA publishes the Manual on Uniform Traffic Control Devices (MUTCD), a guide that contains the national standards governing all traffic control devices, including Traffic Signs and accessories.

All public agencies and owners of private roads open to public travel across the nation rely on the MUTCD to bring uniformity to the roadway, which is critical in highway safety and mobility.
