The 2009 Edition of the Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD), published by the Federal Highway Administration and approved by the Federal Highway Administrator as the national standard for all highways open to public travel, was duly adopted by the Washington state secretary of transportation. Revisions are incorporated into the December 2009 Edition of the MUTCD, except as may be modified herein, when published by the Federal Highway Administration. The manual includes in part many illustrations, some of which depend on color for proper interpretation. The code reviser has deemed it inexpedient to convert these regulations and illustrations to the prescribed form and style of WAC and therefore excludes them from publication. The document is available for public inspection at the headquarters office and all region offices of the Washington state department of transportation. Further, each city, town, and county engineering office in the state will have either a hard copy or an electronic copy of the MUTCD, with revisions and modifications for Washington, in its possession.
