- The MUTCD is a complex and evolving document. The Knowledge element of the FHWA Web site provides historic information about the development of traffic control devices and the MUTCD, and overview of who benefits from the information contained in the publication, and the process for updating standards. There's even a list of frequently asked questions about the MUTCD, which is updated regularly.
MUTCD in Washington State
The MUTCD contains 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 Washington State Department of Transportation (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. Also look at WAC 468-95.
The Millennium Edition (ME) MUTCD is the current adopted (on January 9, 2003) legal version of the MUTCD for use in Washington State. The ME MUTCD and the Washington State modifications are to be used for the installation and maintenance of traffic control devices. Proposed modifications to the ME MUTCD that will be in effect only in Washington State can be submitted electronically to WSDOT using the process described in Modifications to the MUTCD 2003
