Roundabout Directional Sign
A Roundabout Directional Sign is MUTCD compliant for the safety standards of drivers on roadways and parking areas. A Roundabout Directional Sign is a helpful tool to help enforce traffic regulation and display mandatory information to drivers and pedestrians.
Which Material Do I Choose?
Available in 3 MUTCD compliant reflective materials:
- Engineering grade (Type I) - The most economical choice and is best suited for parking lots and low volume roads
- High Intensity Prismatic (Type IV) - The best value based on reflective performance, durability, and price
- Diamond Grade Prismatic (Type IX) - The best choice for superior reflectivity and public roadway usage.
Compliance
Section 2B.43 Roundabout Directional Arrow Signs (R6-4, R6-4a, and R6-4b)
Guidance
- Where the central island of a roundabout allows for the installation of signs, Roundabout Directional Arrow (R6-4 series) signs should be used in the central island to direct traffic counter-clockwise around the central island.
Standard: 02 The R6-4 sign shall be a horizontal rectangle with two black chevron symbols pointing to the right on a white background. The R6-4a sign shall be a horizontal rectangle with three black chevron symbols pointing to the right on a white background. The R6-4b sign shall be a horizontal rectangle with four black chevron symbols pointing to the right on a white background. No border shall be used on the Roundabout Directional Arrow signs.
03 Roundabout Directional Arrow signs shall be used only at roundabouts and other circular intersections.
Guidance: 04 When used on the central island of a roundabout, the mounting height of a Roundabout Directional Arrow sign should be at least 4 feet, measured vertically from the bottom of the sign to the elevation of the near edge of the traveled way.
Option: 05 More than one Roundabout Directional Arrow sign and/or R6-4a or R6-4b signs may be used facing high-speed approaches, facing approaches with limited visibility, or in other circumstances as determined by engineering judgment where increased sign visibility would be appropriate.
