Which action should you take when approaching a roundabout?

Yielding to traffic already in the roundabout is the correct action to take when approaching a roundabout because it ensures a smooth flow of vehicles and minimizes the risk of collisions. Roundabouts are designed to improve traffic flow and reduce the likelihood of accidents by allowing vehicles to move in a circular direction instead of having multiple stop signs or stoplights.

By yielding to traffic that is already in the roundabout, you allow those vehicles to pass without interruption, which promotes safety and efficiency. It’s important to be aware of the traffic signs or road markings that indicate who has the right of way. This understanding helps in merging safely into the roundabout and continuing through without unnecessary delays or dangerous situations.

In contrast, speeding up to enter quickly can lead to potential accidents, as it may put you in the way of other vehicles already within the roundabout. Stopping and waiting for a green light is not applicable in roundabouts, as they operate on a yield system rather than a traffic signal system. Using your horn to notify other drivers is unnecessary and could potentially create confusion or escalate aggressive driving behaviors. Prioritizing yielding is key to navigating roundabouts safely.
