What does a mini-roundabout sign indicate?

The mini-roundabout sign indicates that there is a roundabout ahead, alerting drivers to the upcoming intersection where vehicles will need to navigate a circular road layout. This sign serves as an important warning for motorists to prepare for changing traffic conditions that come with roundabouts, which often promote smoother flow of traffic and reduce delays.

In this context, the sign ensures that drivers can anticipate their need to yield to any traffic already in the roundabout, enhancing safety and efficiency. Understanding this signage is crucial for safe navigation, particularly in areas where roundabouts are common.

The other options describe scenarios related to traffic management and priority rules but are not specifically represented by the mini-roundabout sign itself, which focuses solely on indicating the presence of a roundabout ahead.
