When should you enter a roundabout?

Entering a roundabout safely requires you to assess the traffic flow and find an adequate gap before proceeding. This option emphasizes the importance of waiting for a clear and safe opportunity to merge into the roundabout, which helps prevent collisions. Roundabouts are designed to improve traffic flow and reduce accidents by allowing vehicles to yield rather than come to a complete stop.

Choosing to enter the roundabout when there is an adequate gap ensures that you can navigate the intersection without disrupting the ongoing traffic. This not only helps maintain a steady pace for vehicles already circulating in the roundabout but also promotes a more efficient use of the roundabout system overall. Understanding the timing and spacing when it comes to yielding in these situations is crucial for safe driving practices.

Other options focus on conditions that may not align with safe driving practices. For instance, entering when the light turns green may be relevant to traffic lights but is not applicable at roundabouts. Additionally, entering whenever you see an opening may lead to unsafe situations if that opening is too small or if it causes conflict with other vehicles. Finally, waiting only for others to stop can lead to unnecessary delays and can also be dangerous if it disrupts the flow of traffic. Hence, assessing gaps in traffic is the key to safe and efficient
