Can you change lanes after entering a roundabout?

When approaching and navigating roundabouts, safety and traffic flow are paramount. The correct answer reflects the rules and guidelines established for driving in roundabouts, which are designed to minimize confusion and enhance safety for all road users.

Changing lanes after entering a roundabout is prohibited because it poses a significant risk to both the driver attempting the lane change and other vehicles in the roundabout. Once you enter a roundabout, you should remain in your lane until you exit; this helps maintain a consistent flow and allows other drivers to anticipate your movements. Roundabouts work on the principle of yielding to traffic already in the circle, and abrupt lane changes can lead to collisions or obstruct the movement of other vehicles.

While there are situations where lane changes may be necessary, such as in emergency circumstances or if the situation demands (like avoiding an obstruction), these are exceptions rather than standard practice. The fundamental rule is to remain in your lane once you have entered the roundabout. This reinforces safer driving patterns, reducing the likelihood of accidents and ensuring that the roundabout functions as intended.
