If signs or road markings do not indicate otherwise, when entering a roundabout you must position the vehicle in the right-hand lane if you are turning right or going straight ahead, and in the left-hand lane only if you are turning left. Just like you would at a normal crossroad.

In many roundabouts, however, there are road markings that are different from the standard rules of positioning. The hierarchy of authority ('myndighetspyramiden') tells us that the road markings then outrank the traffic rules.
