What is the correct way to handle a roundabout?

When navigating a roundabout, the primary rule is to yield to the traffic already in the roundabout. This ensures that vehicles already circulating have the right of way, promoting a smooth flow of traffic and reducing the likelihood of accidents. Additionally, signaling when you are about to exit the roundabout is essential. It communicates your intentions to other drivers, allowing them to anticipate your movements and adjust accordingly.

Entering a roundabout without yielding can lead to collisions with vehicles that are already in the roundabout, which is why option A would not be correct. Coming to a complete stop is not necessary unless you are yielding to traffic (which you should do) or there is a stop sign present, which is rare in roundabouts.

The practice of entering the roundabout without looking, as suggested in option C, is unsafe and can result in serious accidents. Situational awareness is crucial when driving, especially in a multi-directional environment like a roundabout.

Using your horn to alert other drivers, mentioned in option D, is generally discouraged as it can cause confusion and create a startled reaction among drivers instead of improving safety. Proper yielding and signaling are much more effective strategies for safely navigating a roundabout.
