	'''History.''' The need for uniform standards was recognized long ago. The American Association of State Highway Officials (AASHO), now known as the American Association of State Highway and Transportation Officials (AASHTO), published a manual for rural highways in 1927, and the National Conference on Street and Highway Safety (NCSHS) published a manual for urban streets in 1930. In the early years, the necessity for unification of the standards applicable to the different classes of road and street systems was obvious. To meet this need, a joint committee of AASHTO and NCSHS developed and published the original edition of the Manual on Uniform Traffic Control Devices (MUTCD) in 1935. That committee, now called the National Committee on Uniform Traffic Control Devices (NCUTCD), though changed from time to time in name, organization, and personnel, has been in continuous existence and contributes to the revisions of the MUTCD. The Federal Highway Administration (FHWA) has administered the MUTCD since the 1971 edition and is the sole authority over its content.

	The ~~U.S. Secretary~~ of Transportation, ~~under authority granted by~~ the Highway Safety ~~Act of 1966, decreed that traffic control devices on all~~ streets ~~and highways open to public travel~~ in ~~accordance with 23 U~~.~~S.C. 109(d)~~ and ~~402~~(a) in ~~each state shall be in substantial conformance with the Standards issued or endorsed by the FHWA~~. ~~In 23 CFR 655.603~~, the ~~MUTCD is adopted as the national standard for any street~~, ~~highway, or bicycle trail open~~ to ~~public travel in accordance with 23 U~~.~~S.C. 109~~(d) and ~~402(a)~~.		'''History.''' The American Association of State Highway Officials (AASHO), now known as the American Association of State Highway and Transportation Officials (AASHTO), published a manual for rural highways in 1927, and the National Conference on Street and Highway Safety (NCSHS) published a manual for urban streets in 1930. To unify both standards, a joint committee of AASHO and NCSHS developed and published the original edition of the Manual on Uniform Traffic Control Devices (MUTCD) in 1935. That committee, now called the National Committee on Uniform Traffic Control Devices (NCUTCD), has been in continuous existence and contributes to the revisions of the MUTCD. The Federal Highway Administration (FHWA) has administered the MUTCD since the 1971 edition and is the sole authority over its content.

	~~'''Support~~.~~''' Sections 226~~.~~010 and 227.220~~ of ~~the Revised Statutes~~ of ~~Missouri authorize MoDOT to prescribe uniform~~ traffic control devices on ~~the state's~~ highways. ~~Pursuant to the provisions of the previously mentioned statutes, at the July 10, 2001, Commission meeting, the Missouri Highways~~ and ~~Transportation Commission~~ (~~MHTC~~) ~~approved and adopted~~ the ~~most current version of~~ the MUTCD as the ~~basis~~ for ~~MoDOT traffic control policy into the future~~ and ~~authorized implementation of actions needed to bring future deviations into compliance~~.		The U.S. Secretary of Transportation, under authority granted by the Highway Safety Act of 1966, decreed that traffic control devices on all streets and highways open to public travel in accordance with 23 U.S.C. 109(d) and 402(a) in each state shall be in substantial conformance with the Standards issued or endorsed by the FHWA. In 23 CFR 655.603, the MUTCD is adopted as the national standard for any street, highway, or bicycle trail open to public travel in accordance with 23 U.S.C. 109(d) and 402(a).

	'''~~Standard~~.''' ~~The traffic control articles~~ of ~~the Engineering Policy Guide (EPG) serve as MoDOT’s Manual on Uniform Traffic Control Devices. The EPG shall be used when applying traffic control devices~~ to ~~state-maintained routes. Any variations from the EPG for~~ traffic control devices ~~shall be approved by~~ the ~~State Highway Safety and Traffic Engineer~~.		'''Support.''' Sections 226.010 and 227.220 of the Revised Statutes of Missouri authorize MoDOT to prescribe uniform traffic control devices on the state's highways.

	'''~~Support~~.''' ~~Starting with the 11th Edition~~ of the ~~MUTCD, MoDOT established a MoDOT MUTCD document~~. ~~The MoDOT MUTCD is only intended to~~ be ~~a historical reference document and not a policy manual. The EPG remains the policy document for practitioners to use~~ when applying traffic control devices to state-maintained routes. ~~The MoDOT MUTCD is displayed in track change mode, indicating differences between MoDOT content and~~ the ~~11th Edition MUTCD, denoting the content MoDOT did not adopt, changes to~~ the ~~manual where MoDOT exceeds MUTCD minimums,~~ and ~~notes indicating the justifications for these variations~~.		'''Standard.''' The traffic control articles of the Engineering Policy Guide (EPG) serve as MoDOT’s Manual on Uniform Traffic Control Devices. The EPG shall be used when applying traffic control devices to state-maintained routes. Any variations from the EPG for traffic control devices shall be approved by the State Highway Safety and Traffic Engineer.

	~~The EPG contains~~ the ~~relevant content from, and is in substantial conformance with,~~ the ~~National~~ MUTCD~~. However~~, MoDOT ~~only adopts those portions of the National MUTCD that are relevant to state-maintained highways, and in many cases~~ MoDOT ~~adopts provisions that exceed those in the National~~ MUTCD. ~~For~~ this ~~reason, the National MUTCD cannot~~ be ~~used as~~ a ~~standalone guide~~ when applying traffic control devices to ~~Missouri~~ state-maintained routes.		'''Support.''' For the 11th Edition of the MUTCD, MoDOT established a MoDOT MUTCD document. Unlike other states, this document is only intended to be a historical reference document and not a policy manual. The EPG remains the policy document for practitioners to use when applying traffic control devices to state-maintained routes. The MoDOT MUTCD is displayed in track change mode, indicating differences between MoDOT content and the 11th Edition National MUTCD, denoting the content MoDOT did not adopt, changes to the manual, and notes indicating the justifications for these variations.

	'''Guidance.''' Like the National MUTCD, the EPG is a permissive manual, meaning the articles of the EPG outline what is permissible regarding the application of traffic control devices to state-maintained roadways. When specific criteria for traffic control devices is not found in the EPG to address a specific concern or application, the Highway Safety and Traffic Division should be contacted for assistance. The Highway Safety and Traffic Division has access to additional resources ~~from which solutions can be sourced~~, such as other MoDOT districts, FHWA, research facilities, and other states. If these solutions have the possibility of being applicable to more than one site, consideration will be ~~given~~ to ~~including~~ the solution in the EPG.		The EPG contains the relevant content from, and is in substantial conformance with, the National MUTCD. However, MoDOT only adopts those portions of the National MUTCD that are relevant to state-maintained highways, and in many cases adopts provisions that exceed those in the National MUTCD. For this reason, the National MUTCD cannot be used as a standalone guide when applying traffic control devices to Missouri state-maintained routes. Practitioners should reference the National MUTCD for standards, guidance, and support related to traffic control devices that are not included in the EPG.

If these solutions have the possibility of being applicable to more than one site, consideration will be made to include the solution in the EPG.

	The articles of the EPG are not a substitute for engineering judgment. It is the intent that the provisions of the EPG be criteria for traffic control devices installed, but not a legal requirement for their installation.
