What should a driver do when approaching a roundabout?

Answer: A — Yield to traffic already in the roundabout

When approaching a roundabout, the correct action for a driver is to yield to traffic already in the roundabout. This means that as you near the circular intersection, you must assess the flow of traffic within the roundabout and allow vehicles in that traffic to pass before merging in. Yielding helps maintain a smooth flow of movement in the roundabout and prevents collisions, as vehicles already in the roundabout have the right of way. By deferring to the vehicles circulating in the roundabout, drivers can safely enter without disrupting ongoing traffic. Other options, such as accelerating to enter quickly or stopping and waiting for traffic to clear, can lead to confusion and potential accidents. Using the left lane for entering is also incorrect, as this may not align with the designated path in a typical roundabout, where the right lane is generally used for entering. Thus, yielding is essential for safe navigation in and around roundabouts.
