Warning of Crosswinds
The sign indicates a stretch of road where strong crosswinds are often present. The symbol is adapted to the conditions at the location.
When You See This Sign
When you see A24 you should immediately prepare for strong crosswinds by reducing speed, keeping both hands on the wheel and increasing the distance to other vehicles. Be extra careful when meeting tall vehicles and when passing exposed open areas such as bridges or coastal stretches where gusts are often stronger.
Rules & Regulations
- A24 is a warning sign and indicates that drivers should be aware that strong crosswinds often occur on the marked road section.
- The sign is not a regulatory sign; it does not impose a binding speed limit or driving prohibition, but road users are expected to adapt their driving to the conditions.
- Heavy and wind-sensitive vehicles (e.g., a truck with a trailer, a caravan, or a motorcycle) should take special care and, if necessary, reduce speed and increase lateral clearance when meeting or overtaking.
- The sign may be supplemented by additional plates indicating the length of the section or a specific direction of the crosswind — follow the information on any additional plates.
Tips for Drivers
- Reduce speed in plenty of time and keep both hands firmly on the steering wheel to handle sudden gusts of wind.
- Increase the distance to the vehicle in front and be extra cautious when meeting larger vehicles or vehicles with high air resistance.
- If you are on a motorcycle, towing a trailer, or driving a caravan, be prepared for strong shifts and consider stopping if the wind conditions feel dangerous.
- Be particularly vigilant when driving over bridges, across open fields, or along coasts where significant wind can occur; a gust can come suddenly.
Common Mistakes
- Believing that the sign implies a mandatory speed limit — it is a warning, not a regulation.
- Underestimating the risk and not holding the wheel with both hands or failing to adjust the distance to other vehicles.
- Thinking the sign only applies to trucks or caravans; passenger cars and especially motorcycles are also affected by crosswinds.

Exam Tip
On the theory test you may be asked whether the sign forces you to slow down or only warns you — the correct answer is that it is a warning sign and not a binding speed order, but you are expected to adapt your driving to the conditions.
Did You Know?
The crosswind warning sign is often placed where local terrain or weather conditions produce recurring gusts of wind, for example near coasts, open plains, bridges or forest edges. The design of the symbol may vary slightly to suit site-specific conditions.
Frequently Asked Questions
Does the warning apply to all vehicles?
Yes, the warning concerns all road users but particularly affects light or tall vehicles such as motorcycles, cars with trailers or trucks. All drivers should adapt speed and driving style to the wind conditions.
Does the sign mean I must stop?
No, the sign does not require stopping. It warns of a risk and you should instead adjust your speed and driving; in extreme cases it may be safer to stop until the wind subsides.
Can the sign have an additional plate?
Yes, A24 is often supplemented with an additional plate indicating the length of the section or the direction the wind comes from. Read and follow the information on any additional plates.
Can I continue to drive in my usual lane during strong crosswinds?
You can drive in your lane but must be prepared for sudden movements and may need to adjust your position in the lane for better stability. Avoid unnecessary lane changes and overtaking in exposed sections.
