What should you do when you approach a roundabout?

When approaching a roundabout, yielding to traffic that is already in the roundabout is the correct action. This is crucial for maintaining a smooth flow of traffic and ensuring the safety of all road users. Vehicles inside the roundabout have the right of way, which helps prevent collisions and confusion. By yielding, you allow those vehicles to pass, and when it is safe to do so, you can enter the roundabout, thereby promoting efficiency in traffic movement.

Accelerating to enter quickly is not advisable, as it can create dangerous situations if the traffic flow is not clear. Signaling left before entering may also mislead other drivers about your intentions, as signaling is typically used to indicate a turn that you are about to make once inside the roundabout. Stopping before entering is unnecessary and can disrupt the flow of traffic, especially if there are no vehicles currently in the roundabout. This reinforces the importance of understanding the yielding rule when it comes to roundabouts.
