Temporary Closure
The device indicates a temporary closure
When You See This Sign
When you see the temporary closure device, you should immediately reduce speed, follow any arrows or diversion signs, and not drive past barriers. If you are unsure, follow instructions from traffic controllers or the police and select a safe lane in good time.
Rules & Regulations
- The device indicates a temporary closure of lanes, the entire road, or part of the road and is legally binding — you must follow the indication.
- The closure may be supplemented by text or pictogram signs, flashing lights, or physical barriers; always follow the combined information.
- If the closure applies to specific categories of traffic or vehicles, this will be indicated on an additional sign — in the absence of such a sign, the closure applies to all traffic.
- Police, traffic controllers, or road workers may give differing instructions; these instructions take precedence over the automatic device.
Tips for Drivers
- Slow down as you approach the device and be prepared to change lanes or follow a designated diversion in good time.
- Look for supplementary signage or illuminated arrows on gantry displays — they often show which lane is open or closed.
- If you are driving in a tunnel or on a motorway, follow the fixed instructions and do not pass barriers even if traffic appears clear.
- Keep distance to the vehicle in front; sudden stops or lane changes are common during temporary closures.
Common Mistakes
- Thinking that the device is only advisory when there are no physical obstacles — it is binding even without a barrier.
- Confusing a temporary closure with a permanent prohibition sign — a temporary closure can change quickly and requires attention.
- Assuming the closure only applies to large vehicles; if nothing is specified, it generally applies to all types of traffic.

Exam Tip
On the theory test you may be asked a question designed to trick you into believing you may pass if there is no physical barrier. The correct answer is that you must comply with the device even when no physical obstacles are visible, unless otherwise specified on an additional sign.
Did You Know?
Temporary closures are often used on motorways, at roadworks, and in tunnels to quickly close a lane or whole stretches of road in the event of accidents or maintenance. Since the introduction of electronic road guidance systems, these devices have become a common tool for dynamic traffic control in Swedish cities.
Frequently Asked Questions
Does a temporary closure apply to all vehicles?
As a rule, the closure applies to all traffic unless an additional sign indicates exemptions for certain vehicle categories. Always read additional signs carefully to see if, for example, buses or emergency vehicles are exempt.
May I pass if I am already in the closed lane when the device is activated?
If you are already in the lane, you should, as far as possible, leave it safely and follow instructions. Do not stop across the road — make a safe lane change or follow the staff's instructions.
What should I do if there is no clear diversion?
Reduce speed and follow temporary signs or the traffic controller's instructions. If no diversion is clear, wait for instructions from the police or traffic controller and do not proceed in uncertainty.
Do the police take precedence over the device?
Yes. Police or another authorized traffic controller may give instructions that differ from the device, and their directions must be followed. Otherwise, the device is legally binding for traffic.
