Warning signs

A warning sign is a traffic sign that alerts drivers to a potential danger or change in road conditions ahead, giving them enough time to slow down and react safely. These signs warn about hazards such as sharp bends, pedestrian crossings, slippery surfaces, merging traffic, animals on the road, or upcoming intersections. Their purpose is not to forbid or command anything, but simply to prepare drivers for situations that require extra attention.

Warning for merging traffic from the right.

Warning for a double curve, first right then left.

Warning for a road narrowing on the right.

Warning for a road with two-way traffic.

Warning for loose chippings on the road surface.

Warning for an obstacle, pass either side.

Warning for a railway crossing without barriers.

Warning for a railway crossing with one track.

1. Stop and give way

This traffic sign means stop and give way. You must come to a complete stop before entering the intersection and give way to traffic that has priority. Proceed only when it is safe.

2. Give way

This traffic sign means give way. Slow down and give way to traffic that has priority. Stop if necessary and proceed only when it is safe.

3. Give way ahead

This traffic sign indicates give way ahead. A give-way requirement applies at the location ahead. Reduce speed in good time and be prepared to stop if necessary.

4. Stop and give way ahead

This traffic sign indicates stop and give way ahead. A stop sign applies at the location ahead. Reduce speed in good time and be prepared to come to a complete stop.

5. Warning for a roundabout

This traffic sign indicates a warning for a roundabout. A roundabout lies ahead. Reduce speed and follow the applicable priority signs, traffic signals and local roundabout rules when approaching and entering it.

6. Priority at the junction

This traffic sign indicates that you have priority at the next intersection. A side road joins from the right, and traffic entering from that side road must give way.

7. Warning for merging traffic from the right

This traffic sign indicates a warning for merging traffic from the right. Traffic travelling in the same general direction may join your traffic stream from the right. Stay alert and adjust your speed or position when necessary to allow traffic to merge safely.

8. Priority at the junction

This traffic sign indicates that you have priority at the next intersection. Side roads join from the left and right, and traffic entering from those side roads must give way.

9. Warning for a curve to the right

This traffic sign indicates a warning for a curve to the right. A right-hand bend lies ahead. Reduce speed before entering the curve, maintain your lane position and use smooth steering.

10. Warning for a sharp curve to the right

This traffic sign indicates a warning for a sharp curve to the right. A tight right-hand bend lies ahead. Reduce speed before entering the curve, remain within your lane and use smooth steering, particularly when visibility or road grip is reduced.

11. Warning for a double curve, first right then left

This traffic sign indicates a warning for successive curves, with the first curve to the right. Reduce speed before entering the winding section, maintain your lane position and be prepared for further changes in direction.

12. Warning for curves

This traffic sign indicates a warning for a series of curves. One or more changes in direction lie ahead and may occur in quick succession. Reduce speed before entering the winding section, maintain your lane position and use smooth steering.

13. Warning for a road narrowing

This traffic sign indicates a warning for a road narrowing. The available width of the road or carriageway decreases ahead. Reduce speed, maintain sufficient lateral clearance and watch carefully for approaching or adjacent traffic.

14. Warning for a road narrowing on the right

This traffic sign indicates a warning for a road narrowing on the right. The available road width decreases from the right side ahead. Reduce speed, follow the lane markings and maintain sufficient clearance from other traffic and the road edge.

15. Warning for a road with two-way traffic

This traffic sign indicates a warning for two-way traffic. Oncoming traffic will use the same road or carriageway ahead. Keep to the correct side of the road and overtake only where it is permitted and clearly safe.

16. Warning for a bad road surface

This traffic sign indicates a warning for a bad or uneven road surface. Potholes, bumps, depressions or other surface irregularities may affect vehicle stability and braking. Reduce speed and avoid sudden manoeuvres.

17. Warning for a steep descent

This traffic sign indicates a warning for a steep descent. A steep downhill gradient lies ahead and the vehicle may gain speed quickly. Reduce speed before the descent, select a suitable gear and use engine braking where appropriate. Allow extra distance for heavy or towing vehicles.

18. Warning for a movable bridge

This traffic sign indicates a warning for a movable bridge. The bridge ahead can open, lift or move to allow water traffic to pass. Reduce speed and be prepared to stop when required by barriers, traffic lights or other signals.

19. Warning for traffic lights ahead

This traffic sign indicates a warning for traffic lights ahead. Traffic signals are located ahead and may not be visible early enough without advance warning. Reduce speed and be prepared to stop if the signal requires it.

20. Warning for falling rocks

This traffic sign indicates a warning for falling rocks. Rocks or stones may fall from nearby slopes or may already be lying on the road. Reduce speed, scan the road ahead and be prepared to avoid or stop for fallen material.

21. Warning for loose chippings on the road surface

This traffic sign indicates a warning for loose chippings. Loose stones or gravel may reduce tyre grip and can be thrown up by passing vehicles. Reduce speed, increase your following distance and avoid sudden braking, acceleration or steering movements.

22. Warning for a slippery road surface

This traffic sign indicates a warning for a slippery road surface. The road ahead may provide reduced tyre grip because of water, ice, mud, oil or another surface condition. Reduce speed and avoid sudden braking, acceleration or steering movements.

23. Warning for a narrowing

This traffic sign indicates a warning for a narrowing ahead. The available road width decreases ahead. Reduce speed when necessary and be prepared for less lateral space between vehicles, obstacles or the road edge.

24. Warning for an obstacle, pass either side

This traffic sign indicates a warning for an obstacle that may be passed on either side. A fixed obstacle or traffic island lies ahead. Pass on either permitted side while following the lane markings and any additional signs.

25. Warning for a divided road

This traffic sign indicates a warning for a divided road. The road ahead separates into carriageways for opposing directions of traffic, usually divided by a central reservation or traffic island. Follow the lane markings and adjust your position to the new road layout.

26. Warning for the end of a divided road

This traffic sign indicates a warning for the end of a divided road. The separation between opposing directions of traffic ends ahead, and oncoming traffic will no longer be divided by a central reservation. Reduce speed and adjust to the new road layout.

27. Warning for an unpaved road surface

This traffic sign indicates a warning for an unpaved road surface. The paved surface ends or changes to gravel, dirt or another loose material. Reduce speed and be prepared for reduced grip, uneven surfaces, dust and loose stones.

28. Warning for cattle on the road

This traffic sign indicates a warning for cattle. Cattle or other livestock may be crossing, walking along or standing near the road. Reduce speed, be prepared to stop and avoid sudden movements or unnecessary use of the horn that could startle the animals.
