Roundabout Rules in Sweden: Priority, Lanes and Signalling Explained
Swedish roundabouts are easier when you separate the situation into three parts: entering, driving inside and exiting. This guide explains the official rules without adding myths that are not in Transportstyrelsen’s guidance.
Quick answer
Traffic entering a Swedish roundabout must give way to vehicles already circulating. There is no special legal requirement to use an indicator simply because you are entering. When you exit, you must indicate to the right. Follow lane arrows and road markings where they are provided.
Roundabouts often feel complicated because several skills happen at once: priority, speed, lane choice, observation and signalling. I recommend learning them in sequence. Decide who you must yield to first, then choose a sensible lane, then plan the exit early.
Watch: Signalling in Swedish Roundabouts
A quick explanation of signalling when entering, changing lanes and leaving a Swedish roundabout.
Continue below for the full explanation, examples and official-source references.
Entering a roundabout in Sweden
As you approach a roundabout, reduce speed and look for vehicles already circulating. Transportstyrelsen states that vehicles entering have a duty to give way to vehicles already in the roundabout. Giving way means slowing in good time or stopping when necessary and entering only when you can do so without danger or obstruction.
You should also scan the area around the entry and exit for pedestrians and cyclists. The roundabout priority rule answers the question about circulating vehicles, but it does not remove other duties toward vulnerable road users.
Do you have to signal when entering?
Transportstyrelsen’s English roundabout brochure says there is no special requirement to use direction indicators when entering a roundabout, because there is only one direction in which you can circulate.
This is an important correction to oversimplified advice you may find online. The legal requirement you should remember clearly is the exit: when you leave the roundabout, indicate to the right.
If you change lanes inside the roundabout, you must use direction indicators for the lane change and may change lane only when it can be done without danger or undue hindrance.
How should you choose a lane?
Choose the lane most suitable for your continued journey. If road signs or road markings give instructions, follow them. This is why one rigid “always use this lane for this exit” rule can be misleading.
Before a multi-lane roundabout, read the lane arrows early. A late lane change creates unnecessary risk and can also make your intentions difficult for other drivers to understand.
Practical method: read the sign → choose the lane → reduce speed → check circulating traffic → enter when safe → prepare the exit → signal right.
Driving inside a multi-lane roundabout
Once inside, keep a stable lane and maintain enough space. If you need to change lane, check mirrors and blind spot as appropriate, signal and move only when the change will not cause danger or unnecessary obstruction.
Transportstyrelsen also reminds drivers that long vehicles may need more than one lane. Do not place yourself unnecessarily beside a large vehicle where its turning path can close the space around you.
Exiting the roundabout safely
Signal to the right before you exit. Transportstyrelsen recommends adapting your driving so that you preferably leave from the right-hand lane. If you leave from the left-hand lane, pay particular attention to vehicles in the right-hand lane because they may continue around the roundabout; in effect, your path involves a lane change.
Do not focus only on cars. As the exit opens up, scan for people crossing and for cyclists. Your speed should give you time to deal with a crossing situation without abrupt braking.
Roundabouts in the Swedish driving test
Trafikverket lists roundabouts among the situations that may appear during the category B practical test. The examiner is interested in how you interact with others, show your intentions, signal, position the car and follow the road rules.
A common training mistake is slowing so much that you lose planning and flow, or entering too quickly because you are concentrating on “not stopping.” The correct speed is the speed that gives you time to observe, decide and proceed safely.
Combine this guide with the right-hand rule and priority rules so you can compare a roundabout with ordinary intersections.

Make roundabouts predictable
Once you understand priority, lane choice and the exit signal separately, even complex roundabouts become a sequence of manageable decisions.
