Who has the right of way in a roundabout?

The simple answer is this: traffic already in the roundabout has the right of way. If you are approaching a roundabout, you are required to yield to vehicles that are already inside it. That means you slow down, look to your left, and wait for a safe gap before entering. If there is no safe gap, you stop and wait. Once you are in the roundabout, you keep moving. You do not stop unless you need to avoid a collision. You also should not change lanes while travelling through the roundabout. A lot of people get confused because they think “right of way” means they can just go. That is not how it works. Right of way does not give anyone permission to force their way through. It simply means other drivers have a duty to yield. Everyone still has a responsibility to drive safely and avoid a collision. So, the rule is: Entering the roundabout? Yield. Already in the roundabout? You have priority. Exiting the roundabout? Signal, check for pedestrians and cyclists, and leave when safe. And remember, pedestrians and cyclists still matter. Drivers entering or exiting a roundabout must watch for people crossing and yield where required. Roundabouts work well when everyone understands the same basic idea: slow down, look left, yield to traffic already inside, and only enter when it is safe. Roundabouts work well when everyone understands the same basic idea: slow down, look left, yield to traffic already inside, and only enter when it is safe. Unfortunately, when drivers don't understand how roundabouts work, what should be a safer and more efficient intersection can quickly become dangerous.
