What must you do at a roundabout?

At a roundabout, it is essential to yield to traffic that is already circulating in the roundabout. This means allowing vehicles that are already on the roundabout to pass before you enter. The purpose of this rule is to maintain the flow of traffic and prevent congestion or accidents. Roundabouts are designed to facilitate continuous movement, and yielding helps ensure that entering traffic does not disrupt the vehicles already navigating through the roundabout.

The design of a roundabout encourages drivers to approach at a reduced speed and merge into a single lane of traffic. It is a common misconception that drivers should stop and wait for a green light, which is not the case at roundabouts. Instead, drivers should assess the situation, yield appropriately, and enter when it is safe to do so. This practice enhances safety and efficiency at intersections compared to traditional traffic signals or stop signs.
