What is the purpose of a roundabout?

To improve traffic flow and reduce accidents To increase speed limits To provide a tourist attraction To direct traffic only in one direction

Correct Answer:

To improve traffic flow and reduce accidents

Explanation:

The purpose of a roundabout is primarily to improve traffic flow and reduce accidents. Roundabouts are designed to enable vehicles to move through intersections smoothly without the need for traffic signals or stop signs, which can cause delays and increase the likelihood of crashes. By allowing vehicles to yield rather than stop, roundabouts minimize the chances of severe collisions that often occur at intersections with traditional traffic signals or stop signs, as they encourage lower speeds and reduce conflict points where accidents are more likely to occur. Additionally, roundabouts help to reduce congestion, as they allow continuous movement of traffic, which can enhance the overall efficiency of road use.
