Roundabout (traffic circle)
This explains how you should behave at roundabouts in Sweden: right of way, lane choice and use of indicators, as well as the difference when the roundabout has a yield sign or not. The material is important for safe and lawful driving and for passing the theory test.
Rules & Regulations
- Right of way: Traffic already circulating in the roundabout normally has priority. If there is a yield sign (the triangle) at the entrance, you must give way to traffic in the roundabout.
- At an entrance without a yield sign, the general right-of-way rules apply instead — in practice this means you must observe who has priority according to those rules (see the question tip below).
- Lane choice in multi-lane roundabouts should be made well before the entrance based on which exit you intend to take; always follow road markings and directional signage if present.
- Indicators: Signal to show what you intend to do. Normally you show the right indicator shortly before you leave the roundabout. If you intend to turn left (pass more than half the roundabout) you should signal left well in time when entering and then switch to the right indicator before the exit.
- Driving behaviour: Maintain a steady, appropriate speed in the roundabout, avoid sudden lane changes and do not stop in the roundabout unless it is absolutely necessary to give way.
- Attention to vulnerable road users: Be especially aware of cyclists and pedestrians at entrances and crossings; follow local signs and road markings at pedestrian crossings and cycle crossings.
- In Sweden, virtually all roundabouts have yield signs (triangle signs) at each entrance — entering traffic must then give priority to traffic already circulating in the roundabout, regardless of the right-hand rule.
- At a cycle crossing (painted with wide white stripes, like a pedestrian crossing) motorists have to give way to cyclists, just as they do to pedestrians at a zebra crossing. At a regular cycle passage (no such marking) the cyclist instead has to give way to vehicles, unless the cyclist is walking the bicycle — always check what type of marking is present at the particular roundabout.
Tips for Drivers
- Choose your lane in good time and position your vehicle clearly before you reach the entrance — sudden lane changes in the roundabout create dangerous situations.
- Always signal right clearly when you are about to leave the roundabout — it helps drivers behind you and others in the roundabout understand your intention.
- If you are unsure who has priority: slow down and wait rather than driving in and creating a conflict. Safety comes before speed.
- If you miss your exit, continue around another lap — reversing or attempting to turn in the roundabout is forbidden and dangerous.
Common Mistakes
- Forgetting to signal right before the exit — which makes it hard for other road users to anticipate your maneuvers.
- Entering the roundabout without giving way when there is circulating traffic — especially at busy roundabouts.
- Choosing the wrong lane and thereby forcing others to brake or change lane in the roundabout.
- Stopping unnecessarily inside the roundabout instead of slowing before the entrance and letting traffic in when needed.
Exam Tip
Theory questions often test the difference between 'roundabout with a yield sign' and 'without a sign' as well as when you should use indicators. Read the question carefully for whether there are signs or road markings — this often determines the answer.
Did You Know?
Many studies and traffic planners show that roundabouts reduce the number of serious accidents compared with traditional intersections, because they force lower speeds and eliminate high-speed collisions in the junction's center.
Frequently Asked Questions
When must I give way in a roundabout?
If the entrance is marked with a yield sign you must give way to traffic already in the roundabout. If unsure: slow down and let other traffic pass.
When should I use indicators in the roundabout?
Show the right indicator well before you leave the roundabout. If you intend to drive more than half a turn (turn left) it is common to signal left before entering and then switch to right before the exit.
How do I choose a lane in a multi-lane roundabout?
Follow road markings and signs. As a rule of thumb the right lane is used for immediate exits (right) and the inner lane for turning left or driving further around the roundabout, but always check local markings.
What do I do if a cyclist is at the crossing at the exit?
Be attentive and adjust your speed. If the cycle crossing or pedestrian crossing gives them priority according to signs and markings you must give way; otherwise show caution and wait until the situation is safe.
