Roundabout Traffic
The sign indicates roundabout traffic
When You See This Sign
When you see the sign for a roundabout you should slow down, assess the traffic in the roundabout, and give way to those already circulating. Choose the correct lane well in advance and use your indicator when you are about to leave the roundabout.
Rules & Regulations
- Sign X9 indicates that the location is a roundabout and that you must follow the traffic flow within it.
- Vehicles already in the roundabout normally have the right of way — yield to them before you enter.
- Choose your lane well before the entry according to road markings and signs; stay in the lane that suits the exit you intend to take.
- Use your indicator when leaving the roundabout and avoid overtaking or sudden lane changes inside the roundabout.
Tips for Drivers
- Slow down before the roundabout so you have time to assess the traffic situation and right-of-way rules.
- Look for markings and arrows on the road surface that show which lane leads to your exit.
- Signal right shortly before you leave the roundabout so other road users know your intention.
- Be extra attentive to vulnerable road users at the entries and exits; cyclists and pedestrians often cross nearby.
Common Mistakes
- Believing that you always have priority when approaching a roundabout — it is the traffic inside the roundabout that normally has the right of way.
- Changing lanes or overtaking inside the roundabout instead of choosing the correct lane before entering.
- Forgetting to signal when leaving the roundabout, which confuses other road users.

Exam Tip
In the theory exam you may get a question that tests both right-of-way rules and signaling: 'Who has priority in a roundabout and when should you signal?' Answer that vehicles in the roundabout have priority and that you should signal when you leave the roundabout.
Did You Know?
Sign X9 belongs to the 'devices' category in the Swedish road sign system and is used to formally mark that a location is arranged for circulating traffic; such devices can be permanent roundabouts or temporary circulations at roadworks.
Frequently Asked Questions
Does X9 mean the roundabout is always large and has multiple lanes?
No. X9 only indicates that there is circulating traffic. Roundabouts can be very small (mini-roundabouts) or larger with multiple lanes; adapt your driving to the specific roundabout's design.
Do I always have to signal left when entering a roundabout?
No. In most roundabouts you normally do not signal on entry. The important signal is to signal right when you intend to leave the roundabout.
Does the same rule on right of way apply to cyclists in the roundabout?
Yes, if cyclists are in the roundabout they have priority just like other vehicles. Be especially careful at junctions and exits where cyclists cross.
Can I stop in the roundabout if I've missed my exit?
No. Do not stop in the roundabout unless it is absolutely necessary (for example, in the event of an accident). Go around again or follow instructions to safely leave the area.
