What is the proper action for drivers planning to turn left at a roundabout?

When approaching a roundabout and planning to turn left, the proper action is to stay to the left as you enter the roundabout. This allows the vehicle to position itself correctly to navigate the roundabout in the intended direction.

By staying to the left, drivers can ensure they are in the appropriate lane to execute a left turn safely and efficiently, avoiding potential collisions with vehicles already circulating in the roundabout or with those entering from different directions. This methodily aligns with the flow of traffic, which typically moves counterclockwise in a roundabout, making it easier for the driver to signal and make a smooth turn.

Considerations regarding the other options highlight the importance of proper positioning when maneuvering through roundabouts: entering from the right side is incorrect because it can disrupt the flow of traffic and increase the risk of accidents, while staying to the right when turning and using the left lane regardless of traffic can lead to confusion and potentially dangerous situations when navigating this intersection type. Proper lane discipline is vital for safety and efficiency in roundabouts.
