What should be avoided when approaching a roundabout?

Answer: B — Stopping in the roundabout

When approaching a roundabout, stopping within the roundabout should be avoided because it disrupts the flow of traffic and can lead to confusion or accidents. Roundabouts are designed to facilitate continuous movement, allowing vehicles to enter and exit without having to stop. When drivers stop in a roundabout, they create an unexpected obstacle for approaching vehicles, which can cause delays and increase the risk of collisions. In a roundabout, the general rule is to yield to traffic already circulating to your right, but once you are in the roundabout, you should maintain your speed and trajectory. Using turn signals appropriately when exiting is important for signaling your intentions to other drivers. Staying in your lane is also crucial for safety and to avoid collisions with other vehicles. However, stopping inside the roundabout is particularly problematic, as it can lead to dangerous situations for both the stopped vehicle and the circulating traffic.
