Status of Rulemaking for the Eleventh Edition of the MUTCD
A Notice of Proposed Amendments (NPA) to issue a new edition of the MUTCD was published in the Dec. 14, 2020, Federal Register for public comment. More than 17,000 entries submitted to the public docket comprise over 35,000 individual comments, and these comments will inform this rulemaking action and the 11th Edition of the MUTCD. In addition, the Infrastructure Investment and Jobs Act directs USDOT to update the MUTCD by no later than May 15, 2023, and at least every 4 years thereafter to promote the safety, inclusion, and mobility of all road users.
FHWA is committed to implementing Section 11135 of the Infrastructure Investment and Jobs Act—the “Bipartisan Infrastructure Law”—which requires FHWA to update the MUTCD to provide for the protection of vulnerable road users and support for the safe testing of automated vehicle technology, among other considerations. FHWA is considering all comments it has received as well as the provisions of the new law as it prepares what we are confident will result in a new and better MUTCD with the 11th Edition.

The NPA closed for public comment in the Federal Register on May 14, 2021.

Current Edition of Manual on Uniform Traffic Control Devices for Streets and Highways
The Manual on Uniform Traffic Control Devices for Streets and Highways, or MUTCD defines the standards used by road managers nationwide to install and maintain traffic control devices on all public streets, highways, bikeways, and private roads open to public travel. The MUTCD is published by the Federal Highway Administration (FHWA) under 23 Code of Federal Regulations (CFR), Part 655, Subpart F.
The MUTCD, which has been administered by the FHWA since 1971, is a compilation of national standards for all traffic control devices, including road markings, highway signs, and traffic signals. It is updated periodically to accommodate the nation's changing transportation needs and address new safety technologies, traffic control tools, and traffic management techniques.
On December 16, 2009 a final rule adopting the 2009 Edition of the MUTCD was published in the Federal Register with an effective date of January 15, 2010. States must adopt the 2009 National MUTCD as their legal State standard for traffic control devices within two years from the effective date. The Federal Register notice, which provides detailed discussion of the FHWA's decisions on major changes from the 2003 edition, can be viewed at http://edocket.access.gpo.gov/2009/pdf/E9-28322.pdf (PDF, 716KB).

Your MUTCD — Guiding You for Over 80 Years
On November 7, 2015, the U.S. celebrated 80th birthday of the MUTCD. Whenever you see an easy-to-read sign, a bright edgeline marking on a foggy night, the countdown timer at a crosswalk, or a well-placed bike lane, take a moment to reflect on the more than eighty years of progress and innovation that the MUTCD embodies. This progress has resulted in safer, more efficient travel on our Nation's roads. Over the years, the MUTCD has unknowingly become the traveler's best friend and silent companion, guiding us on our way along the streets, bikeways, back roads, and highways. As the direct means of communication with the traveler, traffic control devices speak to us softly, yet effectively and authoritatively. From glass "cat's-eye" reflectors to glass beads to microprismatic sheeting, nighttime sign visibility has advanced significantly. Active devices at rail crossings save lives by giving us a positive message about train traffic. And countdown timers on pedestrian signals help us cross a busy street. So the next time you hit the pavement, the path, or the pedals, you can be sure that the MUTCD, through our dedicated professionals who make complex decisions on what devices to install, will help you get where you want to go safely, efficiently, and comfortably! The MUTCD…it's all about you!
