Mississippi Written Drivers Test Practice

What is the primary purpose of roundabouts?

1. To provide a scenic route for drivers

2. To limit the speed of vehicles

3. To improve the flow of traffic and reduce accidents

4. To create additional lanes for parking

The correct answer is: To improve the flow of traffic and reduce accidents

The primary purpose of roundabouts is to improve the flow of traffic and reduce accidents. Roundabouts are designed to facilitate continuous movement and reduce the likelihood of head-on and high-speed collisions, which are more common at traditional intersections with stop signs or traffic lights. By allowing vehicles to yield upon entering the roundabout rather than coming to a complete stop, roundabouts help maintain a steady flow of traffic, thereby decreasing delays and congestion. Additionally, the circular design of a roundabout can help mitigate the severity of crashes, as vehicles are moving at lower speeds and the angle of potential collisions is reduced compared to conventional intersections. This overall enhances safety for both drivers and pedestrians. The other options do not accurately represent the main purpose of roundabouts, as providing a scenic route or creating additional parking spaces are not inherent features of roundabouts, and while they may have an effect on vehicle speed, that is not their primary function.
