What indicates that you are approaching a roundabout?

The presence of a circular arrow sign indicates that you are approaching a roundabout, which is designed to guide drivers in the correct direction of travel around the central island. This sign typically features an arrow that curves to the right or left, depending on the direction of the roundabout, informing drivers to yield and prepare to enter the circular flow of traffic. Recognizing this sign is crucial for navigating roundabouts safely and efficiently, as it alerts drivers to adjust their speed and positioning in preparation for merging into the traffic pattern.

While other signs, such as stop signs, speed limit signs, and pedestrian crossing signs, serve important functions in regulating traffic and ensuring safety, they do not specifically indicate the approach to a roundabout or the necessary actions related to it. Understanding this distinction helps drivers anticipate road conditions and adhere to proper driving etiquette when encountering roundabouts.
