A roundabout is an intersection with an island at its centre. When in a roundabout, you must always keep to the right of the centre island. Roundabouts will be marked with a Roundabout sign and/or priority road sign, and can either be single-lane or multi-lane roundabouts.
The direction of entering the roundabout is alway on right (except driving in UK).
When approaching a roundabout you must slow down and decide which exit you want to leave by. Before entering the roundabout the drivers should look for pedestrians or bicyclists crossings.
When approaching a single-lane roundabout, you must pick a lane as you approach a roundabout.
- if you intend to turn right (leave before/after you are half way round), you must give a change of direction signal to your right as you approach
- if you intend to go straight on, you do not need to give a change of direction signal as you approach.
When approaching a multi-lane roundabout, you must:
- decide which exit you want to leave by
- position your vehicle in the correct lane before you reach the roundabout
- signal (left or right) if you intend turning at the roundabout.
On a multi-lane roundabout, lane arrows and signs will tell you which lane to use, depending on where you want to exit the roundabout.
The right of way in the roundabout is usually signaled by priority road signs. But if there is no a priority road sign you have to apply the rules “priority of the rightmost vehicle”:
Priority of right of way rules – it is a right-of-way system, in which a driver of a vehicle is required to give way to vehicles approaching from the right at intersections. As the vehicle that is turning left must give a way to the opposite incoming vehicle.
An example of unregulated intersection:
The road sign, placed here, is about the entering direction only. There is no road sign about priority of way.
If the roundabout is regulated one, you have to follow the road signs meaning.

In case of entering the roundabout keep moving on the lane you used before the entering!
