The Federal Highway Administration invites local and state agencies to comment on proposed changes to the Manual on Uniform Traffic Control Devices. The proposal is to divide the manual into two manuals--one providing standards and clarifying guidance and option statements and the other providing recommendations and best practices. FHWA is accepting comments on or before March 12, 2013. Get more information here. Submit written comments here.Â
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.
