On Tuesday, December 19, 2023 the U.S. Department of Transportation Federal Highway Administration (FHWA) released the 11th edition of the Manual on 
Uniform Traffic Control Devices for Streets and Highways (MUTCD). This manual is the national standard for traffic signs, signals, and pavement markings to ensure a uniform and predictable environment for people who walk, bike, and drive.
“The Manual on Uniform Traffic Control Devices is a vitally important guidebook that affects safety on countless roads around the country,” said U.S. Transportation Secretary Pete Buttigieg. “With this long-awaited update to the MUTCD, we are helping our state and local partners make it safer to walk, bike, and drive, and embracing new technologies with the potential to make our transportation system safer and more efficient.”
The newly updated MUTCD includes significant input from members of the public, including state and local traffic engineers, traffic control device technicians, and other transportation safety stakeholders, and is the latest edition since 2009.
