What should you do when approaching a roundabout?

Answer: A — Yield to traffic already in the roundabout

When approaching a roundabout, yielding to traffic already in the roundabout is essential for safe navigation. This practice helps ensure that you do not disrupt the flow of vehicles that are already circulating, as they have the right of way. Roundabouts are designed to facilitate continuous traffic flow and reduce the likelihood of collisions; yielding allows for a smoother and safer entry. Entering the roundabout without stopping, speeding up to merge, or ignoring traffic signals can lead to dangerous situations. Entering without stopping can cause abrupt maneuvers for those inside the roundabout, and speeding up may result in losing control or colliding with other vehicles. Ignoring traffic signals undermines the traffic management framework designed to maintain order and safety on the roads. Thus, yielding is the correct and safest action when approaching a roundabout.
