Double Bend Ahead Warning Sign – Diagram 513-B | Permanent UK Traffic Sign

The Double Bend Ahead Warning Sign – Diagram 513-B is a permanent UK road sign used to alert drivers to two consecutive bends ahead, with the first turning to the right. This warning sign improves road safety by giving early notice of potentially hazardous curves, especially on rural, narrow, or winding routes where visibility may be limited.

Designed in full accordance with TSRGD Diagram 513-B, BS EN 12899-1, and Chapter 4 of the Traffic Signs Manual, this high-visibility traffic sign is available in durable aluminium or composite substrate and features RA2 or R3B reflective sheeting for excellent clarity day or night.

The sign is available in six standard triangular sizes: 450mm, 600mm, 750mm, 900mm, 1200mm, and 1500mm, with mounting options including channel fixings, plate-only, or self-adhesive systems. Suitable for both permanent installations and temporary deployments.

🔧 Technical Review

This red-bordered triangular sign contains a bold black arrow symbolising a right bend followed by a left. Its sharply recognisable shape and layout deliver immediate understanding to drivers, helping reduce the risk of loss of control in curved road sections.
