What is the importance of street and direction signs when approaching a roundabout?

Street and direction signs play a crucial role in navigating a roundabout, primarily by guiding drivers on which exit to take. As drivers approach a roundabout, these signs typically indicate the upcoming exits and the roadways that lead to various destinations. This helps prevent confusion and ensures that drivers make informed decisions about their route while maintaining safe and smooth traffic flow.

The other options provide information that, while useful in different contexts, are not specific to the function of signs in a roundabout setting. For instance, speed limit signs are important for regulating vehicle speed but do not directly assist with exit navigation. Additionally, traffic signals are not typically a feature of roundabouts as they operate based on yield principles rather than stop-and-go signals. Lastly, signs displaying information about local attractions serve a different purpose, primarily aimed at tourism rather than traffic navigation within the roundabout. Therefore, the primary value of street and direction signs in this context is their capability to help drivers identify the correct exits, ensuring both efficiency and safety in roundabout travel.
