Manual on Uniform Traffic Control Devices (MUTCD) - Washington State Modifications

The 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 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.
