Manual on Uniform Traffic Control Devices

The Manual on Uniform Traffic Control Devices (MUTCD) contains the standards for traffic control devices that regulate, warn, and guide road users along highways, county roads, and city streets. The MUTCD functions as both a legal and an engineering document. The Revised Code of Washington (RCW) 47.36, Traffic Control Devices, requires the WSDOT to adopt uniform standards for traffic control devices installed along state highways. The law also requires that traffic control devices along county roads fully conform to these adopted standards, and those along city streets conform to the extent possible. 

WSDOT adopted the MUTCD 2009 on November 17, 2011. The MUTCD 2009 and Washington Modification are effective for use in Washington beginning December 19, 2011.

2009 MUTCD Adoption Process

FHWA released the 2009 MUTCD, January 2010. Per Federal regulations, each State has two years to adopt a new edition of the MUTCD as is, or supplement. WSDOT formed a MUTCD Adoption Committee made up of traffic experts from cities and counties (mixture of urban and rural; representatives from the west and east side of the mountains); private consultants representing ITE and bringing their expertise from NCUTCD, NACE, and ATSSA organizations; subject matter experts within WSDOT; and FHWA Division Office – Olympia.

The Adoption Committee reviewed the 55 existing modifications from the 2003 MUTCD contained in Washington Administration Code (WAC) Chapter 468-95, list of 2003 MUTCD Modifications. Based on input from the Adoption Committee, and subsequent WSDOT review, amended 34 of the existing modifications, repealed 11 of the existing modifications, and 10 of the existing modifications will remain the same.

The next step in process was to review the 2009 MUTCD, and 80 proposed modifications were submitted to the committee’s for review. The Adoption Committee submitted 17 proposed modifications to the State Traffic Engineer for approval. After the approval, WSDOT submitted the 17 proposed modifications to FHWA for approval. The Division Office in Olympia for FHWA approved 16 out of the 17 proposed modifications.
