The X3 Marker Board traffic sign in Sweden indicates changes in road conditions that require you to adapt your speed and steering, such as side obstacles, speed bumps, or narrow passages. It is crucial for safe driving, especially in poor visibility, as the striped fields direct you on which side to pass. Always be prepared to slow down and adjust your driving when you encounter this sign.
Learn the key details of the X3 - Marker Board for Side Obstacles, Speed Bumps and Similar Changes road sign, including its function, what it communicates to drivers, and how it applies in real traffic situations in Sweden. Use this overview to understand the sign clearly and recognise it confidently during the Swedish driving theory exam.
This Swedish marker board is used where conditions change in a way that requires drivers to adapt their speed, steering, or lane position. It may be placed to mark the edge of the road or carriageway, to separate opposing traffic flows, or to guide vehicles through complicated narrowings and passages. The board is positioned so that its striped fields slope downward on the side where traffic should pass, making the intended travel side visually clear. In roadworks or similar temporary work situations, it is coloured red and yellow, and the fields may also be horizontal. The device supports safe lane guidance by making edges and separations easier to perceive, especially in poor visibility or complex layouts.
Road conditions have changed and you must adjust your speed and positioning. It marks edges, separates traffic directions, or highlights complex passages.

The X3 Marker Board is a Swedish traffic sign used to alert drivers to changes in road conditions that necessitate a reduction in speed and a potential change in steering or lane position. It commonly marks road edges, separates traffic directions, or guides vehicles through complex or narrow sections.
When you see the X3 Marker Board, you must immediately prepare to adjust your speed and potentially your position on the road. The direction of the sloping fields on the board indicates the side traffic should pass, so pay close attention to this guidance and follow it precisely.
You are likely to see the X3 Marker Board in areas where the road layout changes significantly. This includes places with side obstacles, upcoming speed bumps, narrowing lanes, temporary roadworks (where it might be red and yellow), or where opposing traffic needs to be clearly separated.
A common mistake is not slowing down sufficiently or misinterpreting the direction indicated by the sloping fields. In roadworks, the changes can be more abrupt, so extra caution is advised. Always assume the sign indicates a situation where reduced speed is essential for safety, which is a frequent point tested in the theory exam.
The striped fields on the X3 Marker Board are designed to visually guide you. They slope downwards on the side where traffic should pass. If the stripes slope to your right, you should keep to the right of the marker. If they slope to your left, you should pass on the left.
Yes, the X3 Marker Board can be used to warn drivers of approaching speed bumps or other similar changes in road elevation or surface that require a reduction in speed. It serves as a visual cue to anticipate and slow down for such obstacles.
