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 road layout before entering the junction: the thick line shows how the priority road continues, while the thin line shows a connecting road. Choose the correct road position and use your indicators if you are turning, including when following the priority road through the junction. At the same time, comply with the give-way rules shown by the main sign and the signs applying to your direction of travel.
Rules
- The supplementary plate shows the course of the priority road through the junction in question.
- The thick line represents the priority road, while the thin line represents a connecting road.
- The supplementary plate must be read together with the main sign above it and has no meaning on its own.
- When the priority road bends, you must use your indicators if your manoeuvre involves turning at the junction.
- The sign does not regulate priority between oncoming vehicles that are both on the priority road; the usual rules, including those concerning left turns, still apply.
Tips
- Identify which arm of the diagram corresponds to the road you are approaching from, then follow the thick line to determine the priority road's onward direction.
- Reduce your speed early if the priority road changes direction, so that you have time to position yourself and signal clearly.
- Do not assume that other road users have understood the road layout; pay particular attention to vehicles coming from the narrow side roads.
- Look for lane arrows and other road markings, because the supplementary plate shows priority at the junction, not necessarily which lane you should use.
Common misconceptions
- Learners think that the thick line represents the physically widest road. The line shows the priority road, regardless of the road's actual width.
- Some people believe that indicators are not necessary when following the priority road. You must still signal when turning.
- The sign is confused with a supplementary plate indicating distance or extent, but it specifies neither a distance in metres, a length nor how long a main sign applies.
Test yourself
Easy
What does this supplementary plate tell you?
- AThe wide line shows how long the road section is for which the main sign applies.
- BThe wide line shows the physically widest road, and the narrow line shows the narrowest one.
- CThe wide line shows the distance to the place where the main sign begins to apply.
- DThe wide line shows the forkjørsveg, and the narrow line shows an adjoining road.
Medium
At an intersection, the broad line shows that the forkjørsveg (priority road) bends to the right. You must follow the forkjørsveg. What do you do?
- AI drive straight ahead without signalling because the broad line is only advisory.
- BI follow the forkjørsveg and signal right before turning.
- CI follow the forkjørsveg without signalling because I retain priority.
- DI follow the forkjørsveg and signal left before turning.
Hard
You and an oncoming vehicle are both on the road shown with a broad line. You are going to turn left, while the oncoming vehicle is going straight ahead. What must you do?
- AWait for vehicles from the narrow line, but not for the oncoming vehicle.
- BTurn before the oncoming vehicle because you are following the broad line.
- CTurn at the same time as the oncoming vehicle because the supplementary plate distributes the lanes.
- DWait until the oncoming vehicle has passed before turning.
Theory test tip
In the theory test, the thick line is the key: it shows the priority road, not necessarily the direction straight ahead or the physically widest road. A common trap is to think that someone following the thick line never has to signal or give way to oncoming traffic when turning left.
Did you know
These supplementary plates are used particularly at junctions where the priority road bends in a way that is not obvious from the road layout. The diagram makes it possible to show which road connection has priority, even when a side road may visually appear to be the natural continuation.
Frequently asked questions
What does the thick line mean?
The thick line shows how the priority road runs through the junction. It does not indicate the road's actual width.
Do I have to use my indicators when the priority road bends?
Yes. If you turn at the junction, you must signal even when following the priority road. Having priority does not exempt you from the requirement to signal clearly.
Does traffic coming from the thin line have to give way?
The diagram shows that the thin line is a connecting road, while the thick line is the priority road. The specific give-way rules are determined by the main sign and the signs applying to the different approaches.
Do I always have priority over oncoming traffic when following the thick line?
No. If both you and the oncoming traffic are on the priority road, the usual rules between you still apply, including the rule that a vehicle turning left must give way to oncoming traffic.
