Washington State Manual on Uniform Traffic Control Devices – 2024-2025 Adoption Process

The Federal Highways Administration, also referred to as the FHWA, published the 11th Edition of the Manual on Uniform Traffic Control Devices (MUTCD) in December 2023. The MUTCD sets minimum standards for all Traffic Control Devices used on U.S. roads and highways. This includes all road signs, highway markings, electronic traffic signals, railroad crossings and roadway construction zone areas.

This is the first federal MUTCD update since 2009. Washington state will adopt the MUTCD with state specific revisions in compliance with 23 CFR 633.605. WSDOT is the lead for that process, with local agencies also contributing.

Adoption date

The effective date for the 11th Edition of the MUTCD was Jan. 18, 2024.  Washington has two years from the effective date to adopt the MUTCD with modifications.

Giving feedback

WSDOT plans to collect initial public feedback via an online form, which will be made available on this site as the process develops.
