Who has the right-of-way in a roundabout?

Answer: B — The vehicles already in the circle

In a roundabout, the vehicles already in the circle or roundabout have the right-of-way. This rule is crucial for maintaining a smooth flow of traffic and enhancing safety within the roundabout. When vehicles enter a roundabout, they must yield to those that are already circulating. This prevents collisions and ensures that traffic flows efficiently, as vehicles do not have to stop or slow down unnecessarily for those entering the roundabout. The emphasis on giving priority to vehicles already in the roundabout helps minimize potential conflicts and helps drivers anticipate the movements of others, leading to safer navigation through this traffic control feature. Understanding this fundamental rule is essential for all drivers to ensure proper etiquette and safety while using roundabouts.
