What should you do if you are at a roundabout and plan to take the first exit?

When you approach a roundabout and intend to take the first exit, signaling left before entering is the appropriate action. This alert other drivers of your intention to exit the roundabout at the first opportunity. By signaling left, you are clearly indicating that you will be making a leftward maneuver at the roundabout, which helps to ensure that surrounding traffic understands your course of action.

Continuing the left signal while you are still in the roundabout further reinforces your intent to take that first exit. It maintains clarity and safety for both you and other vehicles, preventing confusion and potential collisions.

The other choices do not align with proper signaling etiquette for this scenario. Signaling right before entering may mislead other drivers into thinking you are intending to go around the roundabout rather than exiting. Not signaling at all fails to communicate your intentions, which can be hazardous in a traffic environment where clear messaging is essential. Lastly, signaling left only after leaving the roundabout does not provide any useful information to other drivers while you are still navigating the roundabout itself.
