How should you approach a roundabout?

When approaching a roundabout, it is essential to yield to the traffic that is already circulating within the roundabout. This rule is in place to ensure a smooth flow of vehicles and to prevent accidents. By yielding, you allow those already in the roundabout to maintain their right of way, which helps to promote safety and efficiency in traffic movement.

Once it is safe and there is a gap in the traffic, you can then enter the roundabout. This approach minimizes delays and encourages a continuous flow of traffic, as drivers are not forced to stop unnecessarily. Understanding this protocol is crucial for driving in a safe manner, especially in areas where roundabouts are commonly used.

The other options do not follow the proper protocol for navigating roundabouts, which could lead to confusion and increased risk of accidents. For example, entering immediately without yielding could cause a collision with vehicles already in the roundabout, stopping before entering could disrupt the flow of traffic, and turning on hazard lights is not appropriate in this scenario as it could signal a problem, leading to misinterpretation by other drivers.
