Road narrows
The sign warns that the road narrows from both sides.
When you see the sign
Be prepared for the carriageway to narrow from both sides, and reduce your speed if necessary. Position your vehicle carefully, watch for oncoming traffic and assess whether there is enough room for the vehicles to pass each other safely.
Rules
- Sign 106.1 warns that the road narrows from both the right and left sides.
- The sign does not give you right of way through the narrow section; any duty to give way must be indicated by other signs or follow from the traffic rules.
- You must adjust your speed so that you can stop within the section of road you can see clearly, especially if oncoming vehicles may make passing difficult.
- The sign does not in itself prohibit overtaking or stopping.
Tips
- Look well ahead to spot oncoming traffic before entering the narrow section.
- Reduce your speed early if the road width, visibility or size of the oncoming vehicle makes passing uncertain.
- Keep a safe distance from the road edge, guardrails and obstacles, but avoid positioning your vehicle unnecessarily close to the centre.
- Look for supplementary plates or other signs that may indicate distance, length or a duty to give way.
Common misconceptions
- Some people confuse the sign with 106.2 or 106.3, but on 106.1 both sides point inwards because the narrowing occurs from both sides.
- Many people think that whoever arrives first always has right of way. The sign alone does not determine who should proceed first.
- Some interpret the sign as an automatic overtaking prohibition, but such a prohibition must be indicated by other signs, road markings or the traffic conditions.

Easy
What does this sign warn about?
- AThe road becomes narrower from the right side
- BThe road has several dangerous bends
- CThe road becomes narrower from the left side
- DThe road becomes narrower from both sides
Medium
You are approaching an unclear narrowing and may meet vehicles that make passing difficult. What should you do?
- AMaintain your speed because oncoming traffic always has vikeplikt (the duty to yield)
- BAdjust your speed so that you can stop within the stretch of road you can see
- CIncrease your speed to get through the narrow stretch first
- DAlways stop before the narrowing even if the road is clear
Hard
You and an oncoming vehicle are approaching the narrow stretch, and no other signs regulate vikeplikt. What follows from this sign alone?
- AThe one driving toward the narrowing always has forkjørsrett through the stretch
- BThe one who arrives first always has forkjørsrett through the stretch
- CThe one with the largest vehicle always has forkjørsrett through the stretch
- DNeither of you has forkjørsrett solely because of the sign
Theory test tip
Look carefully at which side or sides of the symbol bend inwards. If both sides bend inwards, the correct answer is that the road narrows from both sides—not that the road has a dangerous bend or that only one side narrows.
Did you know
The sign’s two black lines mirror the shape of the road ahead: when both lines bend inwards, the road narrows from both sides. On variants 106.2 and 106.3, only one side shows a narrowing.
Frequently asked questions
Does the sign mean that I must give way to oncoming traffic?
No, sign 106.1 is a warning sign and does not establish a duty to give way. Look for specific give-way signs, and adjust your driving so that vehicles can pass each other safely.
Do I always have to stop before the narrow section?
No, you do not have to stop if there is sufficient space and the road ahead is clear. However, you must reduce your speed or stop if the width, visibility or oncoming traffic makes this necessary.
What is the difference between 106.1, 106.2 and 106.3?
Sign 106.1 warns that the road narrows from both sides. Sign 106.2 warns that it narrows from the right, while 106.3 warns that it narrows from the left.
Can a supplementary plate be displayed together with the sign?
Yes, a supplementary plate may, for example, provide information about the distance to the narrowing or the length of the narrow section. Therefore, always read the sign combination as a whole.
