What should you do when approaching a roundabout?

When approaching a roundabout, yielding to traffic already in the roundabout is the correct approach. This is essential because vehicles circulating in the roundabout have the right of way. By yielding, you allow these vehicles to continue their path without interruption, which helps maintain smooth traffic flow and reduces the risk of collisions.

Understanding the appropriate actions in a roundabout is critical for safe and efficient driving. The design of a roundabout is meant to facilitate easier and safer intersections by minimizing the potential for high-speed crashes associated with traditional intersections. By yielding, you not only follow traffic laws but also enhance overall safety for all road users, including pedestrians and bicyclists.

The other options do not align with safe roundabout etiquette. For example, accelerating and entering quickly can lead to dangerous situations, as it may result in conflicts with vehicles already in the roundabout. Stopping until the way is clear might create confusion and disrupt the flow of traffic. Signaling left and proceeding is also inappropriate when entering a roundabout; typically, drivers should signal to indicate their intention to exit the roundabout rather than entering it. Overall, yielding to traffic already in the roundabout is the safest and most effective practice.
