What must you do when turning right at a roundabout?

When turning right at a roundabout, it is essential to signal right as you approach the roundabout to inform other road users of your intention. This signaling is crucial as it enhances safety and helps other drivers anticipate your movements. Once you are about to exit the roundabout, signaling left is important to indicate that you are leaving the roundabout. This two-part signaling process ensures clear communication with other vehicles and pedestrians, minimizing the risk of collisions.

In contrast, signaling left before reaching the roundabout may confuse other drivers about your intentions. Signaling right only if there are no other vehicles does not take into account the importance of communicating with all surrounding traffic at all times, as they may be unsettled by a driver's silence when approaching the roundabout while intending to go right. Finally, choosing not to signal when the roundabout is clear could prevent other road users from being aware of your actions, compromising safety. Therefore, the correct approach is to signal right on approach and left before your exit.
