Course of forkjørsveg
The supplementary sign shows a schematic image of the junction, where a thick line indicates forkjørsveg and a thin line indicates a road where signs 202 “vikeplikt” or 204 “Stop” have been erected.
When you see the sign
Read the diagram before entering the junction: The thick line shows how the priority road continues, while the thin lines show adjoining roads. Work out whether you are approaching on the priority road or from a side road, adjust your speed and comply with the give-way rules indicated by the main sign and the situation.
Rules
- The thick line shows the route of the priority road through the junction.
- The thin lines show roads that join the priority road.
- The supplementary plate must be read together with the main sign above it; it does not introduce a new give-way rule on its own.
- Vehicles coming from an adjoining road must give way to traffic on the priority road where this is indicated by the signs.
- If you are turning left, you must still give way to oncoming traffic going straight ahead or turning right, even if both vehicles are travelling on the priority road.
Tips
- First look for the thick line and compare the diagram with the road approaches at the actual junction.
- Reduce your speed early if the priority road changes direction, so you have a clear view of traffic from all the road approaches.
- Use your indicators when turning or otherwise changing direction, so that other road users clearly understand where you are going.
- Do not blindly assume that others will give way, especially at junctions where the priority road turns.
Common misconceptions
- Thinking that the thick line shows the physically widest or busiest road. It shows the priority road, regardless of the road's width.
- Thinking that the priority road always continues straight ahead. The diagram may show that it turns at the junction.
- Thinking that being on the priority road means you do not have to give way when turning left or to pedestrians and cyclists.
Test yourself
Easy
What does the supplementary plate show?
- AIt shows how long the main sign applies along the road.
- BIt shows the distance to the next intersection.
- CIt shows which road arm is physically widest.
- DIt shows how the forkjørsveg runs through the intersection.
Medium
You are approaching from a road arm shown by a narrow line. A vehicle is approaching on the road arm shown by a wide line. What do you do?
- AYou give way to the vehicle on the forkjørsveg.
- BYou go first because you are continuing straight ahead.
- CYou go first if your road is physically wider.
- DYou always stop, even if the intersection is empty.
Hard
You and an oncoming vehicle are both following the wide line through the intersection. You are turning left, while the oncoming vehicle is going straight ahead. What do you do?
- AYou go first because you are following the wide line.
- BYou give way to the oncoming vehicle before turning.
- CYou wait only if the oncoming vehicle is signaling.
- DYou go first because the forkjørsveg turns left.
Theory test tip
A common trap is to follow the straightest or visually largest road approach. In the theory test, follow the thick line to determine the route of the priority road, while the thin lines only show adjoining roads.
Did you know
The diagram is oriented so that the driver can compare it with the junction from their own direction of approach. This means that the same junction may have supplementary plates with diagrams rotated differently on the various road approaches.
Frequently asked questions
Does the thick line mean that the road is physically wider?
No. The line thickness shows which road is the priority road, not the actual width of the carriageway.
Do I always have priority when driving on the thick line?
Traffic from the thin road approaches normally has to give way where this is indicated by the main signs. However, you must still follow other give-way rules, including when turning left, and give consideration to pedestrians and cyclists.
Do I have to use my indicators when the priority road turns?
You must signal when turning or making another significant lateral change in the vehicle's position. The signal must be given clearly and in good time so that others understand where you are going.
Can the supplementary plate be used on its own?
No, this is a supplementary plate and must be interpreted together with the main sign. It explains how the priority road runs through the relevant junction.
