Relationship with the Manual on Uniform Traffic Control Devices

The Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) (1) and Standard Highway Signs (2), as well as local applicable standards, govern the design and placement of signs. To the extent possible, this guide has been prepared in accordance with the 1988 edition of the MUTCD. However, roundabouts present a number of new signing issues that are not addressed in the 1988 edition. For this reason, a number of new signs or uses for existing signs have been introduced that are under consideration for inclusion in the next edition of the MUTCD. Until such signs or uses are formally adopted, these recommendations should be considered provisional and are subject to MUTCD Section 1A-6, “Manual Changes, Interpretations and Authority to Experiment.”

The following signs and applications recommended below are subject to these conditions:

• Use of YIELD signs on more than one approach to an intersection (Section 7.1.2.1);
• Long chevron plate (Section 7.1.2.2);
• Roundabout Ahead sign (Section 7.1.3.1);
• Advance diagrammatic guide signs (Section 7.1.4.1); and
• Exit guide signs (Section 7.1.4.2).
