Signalling
Indicate right as you leave the roundabout, one exit before your own. Use an indicator on the way in only if you're clearly positioned in the left lane for a late exit. The official Swedish rule: signal out, not in.
Entering, positioning and exiting roundabouts
When entering a roundabout, you must give way to vehicles already inside. Slow down before you reach it — don't brake inside the circle. Choose your lane early and stay in it.
In a small single-lane roundabout, there's one lane to use. In a larger roundabout, your exit decides: right lane for the first exit, left lane to go further round. Signs at the entry tell you which — read them before you turn in.

Once you're inside the roundabout, you have priority over everyone wanting to enter. Don't stop to be 'polite' to a driver at an entry — it confuses and creates a crash risk.
Most common mistake: switching from the left to the right lane mid-roundabout to make your exit. Illegal and dangerous. If you're in the wrong lane, go round once more and try again.
You approach a roundabout. A car is already inside, coming from your left. What do you do? Slow down, stop if needed, let it pass. Whoever is inside always has priority — whether they appear on your left or your right.
