Information signs – automatisk trafikkontroll

What do information signs look like?

Information signs are square, with a blue background, white border and a white symbol with text. There are exceptions to this rule of thumb. Information signs provide information about special rules — including prohibitions and requirements that apply on a particular stretch of road or at a specific location.

Automated traffic enforcement – average-speed section

[object Object]

Is the average-speed enforcement sign important for the theory test and driving test?

The automated traffic enforcement (average-speed measurement) sign is part of the driver's test syllabus, and you may get questions about it on the theory test. Even so, it is not among the most central signs, since you encounter it relatively rarely in everyday driving. It is still useful to know that the sign warns you that your average speed is measured over a longer stretch, and that you therefore must keep the correct speed the whole way – not just at the start and end points.

What is the average-speed enforcement sign?

The sign warns that your average speed is measured between two cameras over a specified stretch. If you maintain a higher speed than the permitted average, you risk a fine.

Where do you encounter this average-speed enforcement sign?

You will see the sign before:

Motorways and express roads – often before long, open stretches.
National and county roads outside built-up areas – where average speed is to be checked.
Tunnels – for average-speed measurement inside the tunnel with a sub-sign about the tunnel section.

Why is the sign important?

The sign contributes to smoother traffic flow and better safety by preventing high speeds over longer stretches. It motivates you to keep the speed limit from start to finish, and the goal is fewer seriously injured and killed.

What happens if you drive too fast through the average-speed enforcement section?

Driving above the permitted average speed can result in a fine (simplified penalty notice), a driver's license fee, and points on your driver's license. In serious cases it can lead to longer reaction time and increased risk of accidents.

Tips for keeping the correct average speed

Use cruise control where possible.
Maintain a steady speed; avoid sudden accelerations.

Frequently asked questions (FAQ)

Does the average-speed measurement apply to all vehicles? – Yes, all motorized vehicles are recorded and must maintain the average speed.
Can I brake hard before a camera and then accelerate again? – No. Average-speed enforcement records the average between two points.
How long is the section usually? – The length is shown on the sub-sign and can vary from a few hundred meters to several kilometers.
Point-based automated traffic enforcement vs. average-speed enforcement? – Point-based enforcement measures the speed at one point, while average-speed enforcement calculates the average speed between two measurement points.
