Is it permissible to change lanes while in a roundabout?

Changing lanes in a roundabout is generally discouraged, and the safest practice is to complete your maneuvering before entering the roundabout. This is because roundabouts are designed to facilitate continuous flow of traffic, and changing lanes within them can create confusion and increase the risk of collisions.

When you are in a roundabout, each entry and exit is structured to help maintain a smooth and predictable flow. By keeping your lane consistent while navigating the roundabout, you allow other drivers to have a clear understanding of your intentions, which enhances safety for everyone.

Therefore, it's advisable to plan your route ahead of time and make any necessary lane changes before approaching the roundabout to prevent hazards associated with lane changes in such a dynamic environment.
