What is the correct procedure for roundabouts?

Answer: A — Yield to traffic already in the roundabout

The correct procedure for navigating roundabouts is to yield to traffic that is already in the roundabout. This means that when you approach a roundabout, you must stop and allow vehicles that are circulating within the roundabout to go first. This rule is in place to maintain a smooth flow of traffic and prevent accidents, as vehicles in the roundabout have the right of way. Yielding also encourages a safer environment by reducing the potential for collisions that can occur when multiple vehicles enter the roundabout simultaneously. The other options do not reflect proper roundabout etiquette. Entering without yielding would disrupt the flow of traffic and increase the risk of accidents. Signaling right to exit is a good practice, but it may not be necessary in every situation or lane, especially if there are multiple exits and lanes; thus, this option oversimplifies signaling rules. Only using the roundabout when traffic is backed up is impractical, as roundabouts are designed to alleviate congestion and should be used regularly for efficient traffic management.
