A roundabout warning sign is designed to inform drivers that they should exercise caution when approaching a roundabout. The purpose of the sign is to alert drivers to the presence of the roundabout ahead, allowing them time to adjust their speed and prepare for navigating the circular intersection safely.

This warning is critical because roundabouts can differ significantly from traditional intersections, requiring specific yielding rules and a change in driving behavior. The sign serves as an important advance notice that encourages drivers to be vigilant, observe traffic patterns, and yield to vehicles already within the roundabout, promoting smoother traffic flow and reducing the likelihood of accidents.

Other choices imply incorrect actions or intentions that do not align with the function of the roundabout warning sign. For instance, preparing to stop for oncoming traffic is not the goal when approaching a roundabout; rather, drivers should be ready to yield as needed. Similarly, entering without yielding contradicts the established rules of roundabout navigation, which emphasizes yielding to circulating traffic. Lastly, while roundabouts are indicated ahead, the actual purpose of the warning sign is more focused on the need for caution rather than merely indicating their presence.
