On December 19, 2023, FHWA released the long-awaited 11th Edition of the Manual on Uniform on Traffic Control Devices (MUTCD), 88 years after the original became our national standard. This new edition includes a number of updates to improve safety for pedestrians, bicyclists, and all road users.

Updating the MUTCD has been a top USDOT priority as part of the National Roadway Safety Strategy (NRSS). Now to include a quadrennial update cycle, the MUTCD aims to be more responsive than ever before in promoting the safe and efficient mobility of all road users.

All U.S. states must adopt the 11th Edition national MUTCD—or adopt a state-based version or supplement that demonstrates substantial conformance—as their legal standard for traffic control devices within two years.

The Federal Register notice, which provides detailed discussion of the final dispositions of major changes from the 2009 Edition, can be viewed here.
