Roundabout Traffic Sign - Meaning and Usage Guide #1840893 (License: Personal Use)

The image shows a standard European-style mandatory roundabout sign: a blue circle with three white curved arrows rotating clockwise, signaling that drivers must enter a roundabout and circulate counterclockwise around the central island. Widely adopted under the Vienna Convention on Road Signs and Signals, this sign is placed before roundabouts to inform motorists of upcoming traffic flow requirements. It ensures orderly movement and reduces collision risk at intersections.

Used on roads approaching roundabouts, especially in Europe and countries following international traffic signage standards; serves instructional, regulatory, and safety purposes for drivers, cyclists, and traffic training materials.
