The Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) is incorporated in FHWA regulations and recognized as the national standard for traffic control devices used on all public roads. FHWA has issued a Notice of Proposed Amendments on the Federal Register to revise standards, guidance, options, and supporting information relating to the traffic control devices in all parts of the MUTCD. The proposed changes are intended to update the technical provisions to reflect advances in technologies and operational practices, incorporate recent trends and innovations, and set the stage for automated driving systems as those continue to take shape. The proposed changes would promote uniformity and incorporate technology advances in the traffic control device application, and ultimately improve and promote the safe and efficient utilization of roads that are open to public travel. 

Comments on the proposed changes are being accepted through May 14, 2021. For additional information on the proposed revisions, view the notice in the Federal Register.
