Highway signs are directly related to the design of the highway and effectively provide travelers with information needed to safely and efficiently complete trips. Signs must have uniformity of meaning. Excessive and inadequate signing can cause traveler confusion.
'''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 AASHO and NCSHS developed and published the original edition of the 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 FHWA has administered [http://mutcd.fhwa.dot.gov/index.htm the ''MUTCD''] since the 1971 edition and is the sole authority over its content since that time.

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.23 CFR 655.603, which adopts the MUTCD 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).

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.


23 CFR 655.603 adopts the ''MUTCD'' 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).  The “Uniform Vehicle Code (UVC)” is one of the publications referenced in the ''MUTCD''.  The UVC contains a model set of motor vehicle codes and traffic laws for use throughout the United States.  States are encouraged to adopt Section 15-116 of the UVC that states, “No person shall install or maintain in any area of private property used by the public any sign, signal, marking, or other device intended to regulate, warn, or guide traffic unless it conforms with the State manual and specifications adopted under Section 15-104.” 


The standards, guidance, options and support material described in this article provide the transportation professional with the information needed to make appropriate decisions regarding the use of traffic control devices on streets and highways.  The material in this edition provides standards that must be satisfied for the particular circumstances of a situation, guidance that is to be followed for the particular circumstances of a situation and options that may be applicable for the particular circumstances of a situation.

Before laying out distances or determining sign sizes, the public agency is to decide whether to use the International System of Units (Metric) or the English equivalent units.  The chosen units should be specified on plan drawings.  The chosen unit of measurement is to be made known to those responsible for designing, installing or maintaining traffic control devices.


Except when a specific numeral is required by the text of an article in this manual, numerals shown on the sign images in the figures that specify quantities such as times, distances, speed limits and weights should be regarded as examples only.  When installing any of these signs, the numerals should be appropriately altered to fit the specific signing situation.

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 AASHO and NCSHS developed and published the original edition of the 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 FHWA has administered the MUTCD since the 1971 edition and is the sole authority over its content since that time.

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.23 CFR 655.603, which adopts the MUTCD 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).

Support. Missouri Revised Statue 300.135 states “All traffic control signs, signals and devices shall conform to the manual and specifications approved by the state highways and transportation commission or resolution adopted by the legislative body of the city. All signs or signals required hereunder for a particular purpose shall so far as practicable be uniform as to type and location throughout the city. All traffic control devices so erected and not inconsistent with the provisions of this ordinance shall be official traffic control devices.”

September 12, 1961, the Commission first adopted the provisions of the Manual on Uniform Traffic Control Devices (MUTCD) and authorized the department staff to bring signing, marking, and signalization on the State Highway System into conformity therewith. On July 10, 2001, the Commission approved the most current version of the MUTCD as the basis for MODOT traffic control policy into the future and authorized implementation of actions need to bring future deviations into compliance.

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. The MUTCD cannot be used as a standalone document without the EPG when applying traffic control devices to state maintained routes as MoDOT does not adopt all options found in the MUTCD as many do not apply. In addition, MoDOT’s standards for the application of traffic control devices may exceed the MUTCD minimums and therefore not referencing the EPG as the primary guidance can result in substandard applications on state maintained routes. Any variations from the EPG guidance for traffic control devices shall be approved by the State Highway Safety and Traffic Engineer.

Guidance. Like the MUTCD, the traffic control articles of the EPG are permissive guidance, meaning these articles outline what is permissible regarding applying traffic control devices to MoDOT roadways. When specific traffic control guidance 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 division office has access to additional resources, such as other MoDOT districts, FHWA, research facilities and other states, from which MUTCD compliant solutions can be sourced. If these solutions have the possibility of being applicable to more than one site, consideration will be made to include the solution into the EPG guidance.
