When approaching a roundabout, what should drivers do?

When approaching a roundabout, drivers should yield to vehicles that are already in the roundabout. This rule is crucial for maintaining a smooth flow of traffic and preventing potential accidents. Roundabouts are designed to facilitate continuous movement and reduce the likelihood of collisions by allowing vehicles to enter only when it is safe. By yielding to those already circulating in the roundabout, drivers help to ensure that the traffic flow remains uninterrupted and orderly.

Understanding the importance of yielding is essential, as it contributes to overall road safety. It also enables drivers to anticipate the movements of others, promoting a more predictable driving environment. This rule is typically reinforced by road signage, which indicates that vehicles entering the roundabout must give way.

The other choices present actions that could disrupt the flow and safety of traffic. For instance, speeding up before entering the roundabout could lead to difficulties in merging with vehicles that are already moving. Ignoring yield signs undermines the fundamental traffic rules designed for safe driving practices. Additionally, while waiting for pedestrians is important, it does not take precedence over the need to yield to existing traffic in the roundabout, which should always be prioritized to avoid conflicts.
