What should you always do when approaching a roundabout?

When approaching a roundabout, it is crucial to yield to traffic that is already within the roundabout. This rule is in place to ensure smooth and safe navigation through the roundabout. Roundabouts are designed to facilitate a continuous flow of traffic, and yielding to the vehicles already circulating helps prevent collisions and ensures that all drivers can navigate the intersection safely. By yielding, you allow those already in the roundabout to exit while you wait for an appropriate gap to enter. This practice enhances overall traffic efficiency and reduces the likelihood of accidents.

Other options present actions that are contrary to safe driving practices. Speeding up to enter rapidly can lead to dangerous situations as you may not be able to judge the flow of traffic properly. Driving straight through without stopping disregards the fundamental rules of yielding and can result in collisions with vehicles already in the roundabout. Honking to alert others is not an appropriate response when approaching a roundabout, as it can create confusion and escalate tensions among drivers instead of promoting safety. Thus, yielding serves as the best and safest approach to navigating a roundabout.
