Side Winds Likely Ahead Warning Sign – Diagram 581 | Permanent UK Traffic Sign

The Side Winds Likely Ahead Warning Sign – Diagram 581 is a critical UK road warning sign designed to alert motorists of areas where sudden or strong crosswinds may affect vehicle control. These conditions are especially hazardous for high-sided vehicles, caravans, motorbikes, and cyclists, making early warning essential for road safety.

Manufactured in strict compliance with TSRGD Diagram 581, BS EN 12899-1, and Chapter 4 of the Traffic Signs Manual, this sign is made from high-quality materials including aluminium, composite substrate, or durable self-adhesive vinyl. It is completed with RA2 or R3B reflective sheeting, ensuring optimal visibility during day, night, or adverse weather.

Available in all UK standard triangular sizes — 450mm, 600mm, 750mm, 900mm, 1200mm, and 1500mm — and can be supplied with channel rails, plate-only options, or self-adhesive backing for easy and secure installation on all road types.
