11th Edition of the MUTCD

The National Uniform Traffic Control Device Committee and the Federal Highway Administration (FHWA) are in the final stages of review and publication of the 11th Edition of the Manual on Uniform Traffic Control Devices (MUTCD), which is anticipated in 2023.

The proposed updates to the manual smartly envision the future of transportation by considering the preparedness of our nation’s highways for automated vehicles. They also renew attention on safety for our most vulnerable road users, including the nation’s highway workers, emergency responders, cyclists, and pedestrians.

What is the Future of the MUTCD?

In the future, FHWA expects that the MUTCD will be updated more frequently through revisions, with a new revision every few years. Revisions are a more focused and manageable rule making process compared to full updates to the MUTCD. Future MUTCD editions are envisioned to be published at five- to eight-year intervals.
