What action is required when approaching a roundabout?

When approaching a roundabout, yielding to traffic that is already in the roundabout is essential because it maintains a smooth flow of traffic. Vehicles that are already circulating in the roundabout have the right-of-way, and yielding helps prevent collisions and ensures safety for all road users.

Establishing this practice is critical for effective traffic management, particularly at intersections where multiple roads converge. Yielding allows drivers to assess gaps in traffic, enabling safe entry into the roundabout when conditions allow. It enhances the efficiency of roundabouts, which are designed to reduce congestion and improve safety by minimizing the need for stops.

In contrast, stopping before entering the roundabout (as suggested in one of the options) is not required unless it's to yield to traffic or pedestrians. Speeding through without stopping negates the safety benefits of yielding and creates a hazardous situation. Signaling only a right turn is insufficient because drivers should signal their intentions clearly when entering and exiting the roundabout, regardless of their direction. Understanding the yielding requirement is crucial for safe navigation through roundabouts.
