Arizona Driving Permit Written Practice Test

What should a driver do when approaching a roundabout?

1. Yield to traffic in the roundabout

2. Always stop before entering

3. Enter immediately without yielding

4. Signal left before entering

The correct answer is: Yield to traffic in the roundabout

When approaching a roundabout, the driver should yield to traffic that is already within the roundabout. This is a crucial safety measure designed to ensure smooth traffic flow and to minimize the risk of collisions. Traffic in the roundabout has the right of way, allowing vehicles already circulating to continue without interruption, which helps maintain an orderly movement of vehicles through the intersection. Yielding before entering also allows drivers to gauge the speed and distance of oncoming vehicles, making it safer for them to merge into the roundabout. Implementing this practice helps prevent bottlenecks and reduces the chances of accidents that could occur if drivers were to enter without yielding. Other options suggest actions that may disrupt traffic flow or create unsafe conditions, such as stopping unnecessarily or entering without regard for vehicles already navigating the roundabout. Therefore, yielding to traffic is essential for promoting safety and efficiency at these intersections.
