Warning for Uneven Road
The sign indicates such irregularities or damage in the road surface that it is advisable to travel at a lower speed than would otherwise be the case.
When You See This Sign
When you see the Warning: uneven road sign, immediately reduce speed to a level where you can pass safely without hard jolts. Keep a firm grip on the steering wheel, increase the distance to the vehicle ahead, and be prepared for the irregularities to continue for a longer distance or be followed by multiple damaged spots.
Rules & Regulations
- The sign is a warning sign (A8) and indicates that there are irregularities or damage in the roadway that require caution.
- The sign does not specify a specific speed limit; the driver must adjust their speed according to the condition of the road surface and visibility.
- The sign's placement is intended to give drivers time to reduce speed — it is normally placed at a warning distance before the uneven section and may be complemented by a supplementary plate showing the distance or length of the section.
- The warning remains in effect until the hazard ends or until another sign or intersection clearly changes the conditions; you are obliged to adjust your driving so that you do not cause danger or damage.
Tips for Drivers
- Reduce speed gradually before reaching the uneven surface to avoid hard jolts that can damage the vehicle or make it difficult to control.
- Keep a firm grip on the steering wheel and avoid sharp steering inputs or heavy braking that can cause you to lose grip, especially on a motorcycle or in slippery conditions.
- Increase the distance to the vehicle in front so you have time to react to unexpected holes or bumps and so you are not forced to brake suddenly.
- Pay attention to any supplementary plates that show the distance or length of the uneven section and adjust your planned speed accordingly.
Common Mistakes
- Believing the sign means a fixed speed limit — the sign only warns and does not specify an exact speed.
- Assuming it is always a single hump or a short stretch — it can be a longer section with damage or multiple irregularities.
- Making sudden evasive maneuvers to avoid irregularities without checking the traffic situation, thereby creating danger for others.

Frequently Asked Questions

Can the sign show how long the uneven section is?
Yes, the warning sign is often supplemented with a supplementary plate indicating the distance to the hazard or the length of the uneven section. If such a plate is present, use the information to plan your speed adjustment.
Does the warning also apply to cyclists and motorcyclists?
