A roundabout sign is a traffic sign used to indicate the presence of a roundabout ahead. It typically warns drivers to slow down and yield to traffic already circulating in the roundabout. The sign often features a circular arrow symbol indicating the direction of travel around the roundabout, which is clockwise in left-hand traffic countries and anticlockwise in right-hand traffic countries.

Purpose and Design of Roundabout Signs

• The roundabout sign is designed to prevent drivers from entering the roundabout the wrong way by showing the correct direction of travel.
• It is usually placed before the roundabout to alert drivers to prepare to give way and navigate the circular junction safely.
• In many cases, the sign is placed in consistent locations such as the bottom right-hand corner of the approach to the roundabout.
• These signs contribute to reducing collisions by informing drivers about the priority rules and the proper flow of traffic in the roundabout.

Appearance and Placement

• The sign can vary by country but generally includes arrows forming a circle indicating the direction of travel.
• In some countries, the sign background may be yellow with black arrows, while others use different color schemes based on local traffic sign regulations.
• Additional signs or road markings may complement the roundabout sign to provide further instructions, such as lane usage or signaling.

Traffic Rules Connected to Roundabout Signs

• Drivers must give way to traffic already on the roundabout.
• Signaling is required when exiting the roundabout.
• Mini-roundabouts use similar signs but may also have a painted circle or low dome that vehicles can drive over.
• The presence of a roundabout sign typically implies a reduction in speed to maintain safety through the junction.
