Quayside or Riverbank Ahead Warning Sign – Diagram 555 | Permanent UK Traffic Sign


The Quayside or Riverbank Ahead Warning Sign – Diagram 555 is a critical UK road warning sign used to inform drivers of a sudden and dangerous drop into water — such as at harbours, docks, canal paths, or riverside roads. It is designed to prevent vehicles from inadvertently driving into bodies of water and is especially vital for night-time driving or unfamiliar routes near coastal or inland waterways.

Manufactured to exacting standards and compliant with TSRGD Diagram 555, BS EN 12899-1, and Chapter 4 of the Traffic Signs Manual, this sign is available in aluminium, composite, or self-adhesive sticker substrates, and features RA2 or R3B reflective sheeting for visibility in poor lighting and adverse weather.

Available in all UK-standard triangle sizes — 450mm, 600mm, 750mm, 900mm, 1200mm, and 1500mm — and offered with channel fixings, plate-only, or self-adhesive backing, the sign is suitable for both permanent waterfront installations and temporary warning zones.


🔧 Technical Review
