MUTCD/Utah

A Utah MUTCD–specific sign

The Utah Manual on Uniform Traffic Control Devices (Utah MUTCD) is the standard for road signs, signals, and markings in the U.S. state of Utah. It is developed by the Utah Department of Transportation (UDOT) to "provide guidance so highway signing can be designed in a uniform manner" in conjunction with the national MUTCD developed by the Federal Highway Administration.

The Utah MUTCD defines the content and placement of traffic signs. The Utah Department of Transportation Sign Manual supplements this standard with additional detailed guidelines. Design specifications are detailed in the Utah Standard Highway Signs Supplement.

Usage in OpenStreetMap

A traffic sign specific to the Utah MUTCD is mapped as a node tagged traffic_sign=US:UT:Z1-2, where "US:UT" is the state's ISO 3166 code and Z1-2 is the sign's alphanumeric designation.

Sign designations

Each standard sign or plaque in the Utah MUTCD and Standard Highway Signs Supplement is assigned an alphanumeric designation and organized by series. A sign designation follows the same format as in the national MUTCD and SHSD; however, the sign designation for a state-specific sign includes an "S" after the category. Unlike other states, Utah also assigns individual designations to entire sign assemblies.
