What should you do if you encounter a roundabout?

Yielding to traffic already in the roundabout and entering when it is safe is the correct approach when encountering a roundabout. This practice is essential because roundabouts are designed to facilitate the smooth flow of traffic, reducing the likelihood of accidents compared to traditional intersections. Vehicles that are already circulating within the roundabout have the right of way, and yielding ensures that drivers do not disrupt the flow or create potential hazards.

This method encourages safe merging and allows drivers to assess gaps in traffic so they can enter the roundabout smoothly when it is clear, thus minimizing delays and enhancing overall traffic efficiency. By following this procedure, drivers contribute to a more predictable traffic environment, which is particularly important in multi-lane roundabouts where the movements of various vehicles must be carefully coordinated.

Other options do not align with the safest practices for navigating a roundabout. Stopping before entering, regardless of traffic, could create confusion and lead to rear-end collisions. Speeding up to merge can be dangerous, as it compromises the safety of entering the roundabout maneuver. Finally, always turning left is not applicable as roundabouts typically allow for various exit directions based on the driver’s intended route.
