Some cities and counties adopt WSDOT or other standards. See your city or county code for these standards. For projects with federal funding, see the Local Agency Guidelines (LAG) manual.
The United States Code of Federal Regulations (CFR) Title 23 Highways, Section 655.603 requires that states follow the Manual on Uniform Traffic Control Devices (MUTCD). Revised Code of Washington (RCW) 47.36.030 requires that agencies in Washington state follow uniform standards for the placement of traffic control devices. Washington Administrative Code (WAC) 468-95 makes the 2009 MUTCD that standard. WAC 468-95 modifies sections of the MUTCD for Washington state's laws and unique circumstances.
