When approaching a roundabout, what should you do?

The correct approach when approaching a roundabout is to yield to traffic already in the roundabout. This ensures a smoother flow of traffic and helps to prevent accidents. Vehicles that are already circulating in the roundabout have the right of way, and yielding allows you to assess any gaps in traffic before merging safely.

Understanding the dynamics of a roundabout enhances safety for all road users. By yielding, you not only comply with traffic regulations but also contribute to the efficiency of traffic flow, minimizing the risk of collisions. This practice helps maintain order at a junction where multiple paths meet, allowing for a quicker passage through the intersection.

The other options suggest actions that could compromise safety and traffic flow. Speeding up to merge with traffic can lead to dangerous situations, as it may involve entering the roundabout at an inappropriate speed or cutting off other vehicles. Taking the first exit regardless of signs ignores important directional information and could lead to confusion or accidents. Stopping completely is not necessary unless a stop sign indicates otherwise and could create hazards for drivers behind you who are expecting you to yield rather than stop. Yielding is the safest and most effective practice when approaching a roundabout.
