The side winds sign features a black windsock symbol on a triangular white background with a red border. This sign appears on roads exposed to strong crosswinds, such as bridges, open motorways, and coastal routes, to warn drivers of sudden gusts. The sign indicates a risk of side winds affecting vehicle stability and control. When you see this sign, reduce speed, grip the steering wheel firmly, and prepare for sudden wind gusts that can push your vehicle sideways. Related signs include the “falling or fallen rocks” sign, warning of debris on the road, and the “slippery road” sign, indicating reduced traction due to environmental conditions.
Appearance and Where the Side Winds Sign Is Used
The side winds sign is a triangular warning sign with a white background and a red border. The centre of the sign contains a black windsock symbol, tilted to indicate strong crosswinds. The triangular shape follows the standard design for UK warning signs, ensuring visibility and recognition. The red border alerts drivers to potential hazards, while the windsock symbol provides a clear visual cue of wind-related dangers.

Where is the side winds sign placed?
The sign is placed on open roads, exposed bridges, coastal routes, and motorways where strong crosswinds can affect vehicle stability.
What does the black windsock symbol represent?
The black windsock symbol indicates areas where crosswinds or gusty winds can push vehicles sideways, affecting handling and control.
Is the side winds sign used on all roads?
The sign appears on high-risk locations where side winds can affect driving safety, such as motorways, bridges, and exposed rural roads.
Meaning of Side Winds Sign
The side winds sign warns drivers of strong crosswinds that can affect vehicle stability and control. Crosswinds push vehicles sideways, increasing the risk of lane drift or loss of control, especially for high-sided vehicles, motorcyclists, and vehicles towing trailers. The sign alerts you to adjust driving behaviour by reducing speed, maintaining a firm grip on the steering wheel, and staying alert to sudden gusts. The windsock symbol on the sign visually represents wind direction and potential intensity. Authorities place this sign in areas exposed to sudden wind gusts, such as bridges, open motorways, and coastal roads.
How do side winds affect driving?
Side winds push vehicles sideways, making it harder to maintain lane position and increasing the risk of losing control.
Why is the side winds sign important for motorcyclists?
Motorcyclists are more vulnerable to crosswinds due to lighter weight and less surface contact, making sudden wind gusts harder to counteract.
How do side winds impact high-sided vehicles?
High-sided vehicles, such as lorries and vans, have large surface areas, making them more susceptible to wind-induced swaying or tipping.
Can side winds cause accidents?
Strong crosswinds can push vehicles into other lanes, off the road, or into obstacles, increasing the risk of collisions.
What should drivers do immediately after seeing the side winds sign?
Drivers should slow down, grip the steering wheel firmly, remain aware of vehicle movement, and avoid sudden steering adjustments.
Actions to Take When You See the Side Winds Sign
When you see the side winds sign, take immediate action to maintain control of your vehicle. Reduce speed gradually to increase stability and minimise the effect of sudden wind gusts. Grip the steering wheel firmly with both hands to counteract any unexpected force pushing your vehicle sideways. Stay in your lane and avoid overcorrecting if you feel wind resistance. Leave extra space between your vehicle and others, especially high-sided vehicles, motorcycles, and cyclists, as they are more affected by strong crosswinds. Stay alert for changes in wind intensity when passing through exposed areas such as bridges, open roads, and coastal routes. Avoid overtaking large vehicles, as their movements can become unpredictable in strong winds.
How should you adjust your speed when approaching the side winds sign?
Reduce speed gradually to improve control and reduce the impact of crosswinds.
Why is it important to grip the steering wheel firmly in strong winds?
A firm grip helps maintain vehicle stability and prevents unintended lane drift caused by wind pressure.
Should you change lanes when driving in side winds?
Stay in your lane unless necessary, as sudden lane changes can increase instability in windy conditions.
How much space should you leave between your vehicle and others?
Increase following distance to allow for sudden movements caused by wind, especially near high-sided vehicles and motorcycles.
Is it safe to overtake when side winds are strong?
Avoid overtaking large vehicles, as wind can cause them to sway or shift unexpectedly.
How do you recognise when side winds are getting stronger?
Watch for movement in other vehicles, shaking road signs, and tilting trees or vegetation as indicators of increasing wind intensity.
