Automatic traffic enforcement – section measurement
The sign indicates automatic traffic enforcement – section measurement.
When you see the sign
Check your speed and stay within the posted or general speed limit throughout the measured section. The system calculates your average speed between the control points, so maintain a steady and legal speed. The sign does not change the speed limit.
Rules
- The sign warns that your average speed will be measured over a specific section of road.
- The applicable speed limit applies at every point along the section, even if your average speed is lower than the limit.
- The sign does not introduce a new speed limit; you must follow separate speed-limit signs or the general speed limit.
- An average speed above the applicable speed limit may result in penalties for speeding.
Tips
- Check the applicable speed limit as you pass the sign, and watch for any changes further along the section.
- Maintain a steady speed and use cruise control when conditions make it safe to do so.
- Do not brake suddenly at the control points; it is the time taken to travel the entire section that is used in the calculation.
- Allow for extra margin on downhill sections, where your speed can easily increase without you noticing.
Common misconceptions
- Thinking that only your speed right next to the cameras is checked.
- Thinking that you are allowed to exceed the speed limit along the way as long as your average speed stays below the limit.
- Mistaking the sign for a speed-limit sign or a sign indicating a motorway.
Test yourself
Easy
What does this sign mean?
- AA lane for heavy traffic begins at this point.
- BThe traffic rules for motorveg apply from this point.
- CThe speed is measured only by an ordinary speed camera.
- DThe average speed is measured over a specified section of road.
Medium
The speed limit is 70 km/h when you pass this sign. How should you drive through the control section?
- AFollow 80 km/h because the sign introduces this speed limit.
- BKeep the speed within 70 km/h only at the cameras.
- CKeep the speed within 70 km/h throughout the entire section.
- DDrive above 70 km/h if you reduce your average speed later.
Hard
You pass this sign on an ordinary road, without a sign for motorveg or motortrafikkveg being installed. What effect does the sign have?
- AIt introduces motorveg but retains the previously posted speed limit.
- BIt introduces motortrafikkveg but retains the previously posted speed limit.
- CIt warns of section measurement but changes neither the road type nor the speed limit.
- DIt introduces a heavy-traffic lane but does not change the applicable speed limit.
Theory test tip
A common trap is to answer that the sign warns of an ordinary speed camera or introduces a specific speed limit. Its correct meaning is that your average speed is measured over a section, while the speed limit is indicated separately.
Did you know
With section-based speed measurement, your average speed is calculated from the time your vehicle takes to travel between two control points whose distance is known. This means your speed is checked over a longer section of road, not just at a single point.
Frequently asked questions
Is my speed only measured when I pass the cameras?
No, the system records the times you pass the control points and calculates your average speed between them. However, the speed limit applies at all times and at every point along the section.
Does the sign indicate the applicable speed limit?
No, the sign only warns that your speed will be measured over a section. You must follow the applicable speed-limit signs or the general speed limit.
Can I drive too fast for a short while if my average speed ends up being low enough?
No, you are not allowed to exceed the speed limit on any part of the section. A lower average speed does not make a local speeding offence legal.
What happens if the speed limit changes along the way?
You must follow the speed limit that applies to each part of the road. Therefore, pay attention to new speed-limit signs throughout the measured section.
