Drivers entering a roundabout or traffic circle:
A. Must stop before entering. B. Must yield to drivers in the roundabout or traffic circle.
C. Have the right of way if they arrive first.
D. Have the right away if there are two lanes.
The Correct Answer and Explanation is :
The correct answer is B. Must yield to drivers in the roundabout or traffic circle.
Explanation:
When entering a roundabout or traffic circle, drivers are required to yield to traffic already in the roundabout. This ensures a smooth flow of traffic and minimizes the risk of accidents. The general rule is that vehicles circulating within the roundabout have the right of way. This differs from traditional intersections, where drivers must yield to oncoming traffic when making a turn.
Why the Other Options are Incorrect:
- A. Must stop before entering: It is not required to stop unless there is a specific sign or signal indicating so. Typically, drivers can enter a roundabout without stopping, as long as the way is clear. Stopping unnecessarily can cause congestion and disrupt traffic flow.
- C. Have the right of way if they arrive first: While it’s true that the first vehicle to arrive at an intersection often has the right of way, this does not apply to roundabouts. In roundabouts, vehicles already inside have the right of way, regardless of who arrives first. This helps prevent accidents and ensures a continuous flow of traffic.
- D. Have the right of way if there are two lanes: The number of lanes in a roundabout does not change the general rule that vehicles within the roundabout have the right of way. Multiple lanes may be present to accommodate higher traffic volumes, but the rule about yielding to traffic inside the circle remains the same.
Roundabout Safety:
Roundabouts are designed to improve safety and traffic efficiency. They reduce the likelihood of serious accidents compared to traditional intersections, primarily by reducing the severity of crashes (because of the lower speeds) and eliminating the possibility of head-on collisions. Yielding to traffic already in the roundabout helps maintain a continuous flow and reduces congestion, which is especially important during high traffic periods.
