Low Flying Aircraft or Sudden Aircraft Noise Likely Ahead Warning Sign – Diagram 558 | Permanent UK Traffic Sign


The Low Flying Aircraft or Sudden Aircraft Noise Likely Ahead Warning Sign – Diagram 558 is an important UK traffic sign used to warn drivers of areas near airfields, military bases, or low-altitude flight paths. In these zones, the unexpected appearance of low-flying aircraft or sudden loud noise may startle drivers or cause distractions, particularly for nervous or inexperienced motorists.

Fully compliant with TSRGD Diagram 558, BS EN 12899-1, and Chapter 4 of the Traffic Signs Manual, this permanent warning sign is constructed from aluminium, composite material, or self-adhesive vinyl and finished with RA2 or R3B reflective sheeting for high visibility day and night.

It is available in all UK standard triangle sizes — 450mm, 600mm, 750mm, 900mm, 1200mm, and 1500mm — and can be supplied with channel fixings, plate-only options, or adhesive backing to suit all installation types.


🔧 Technical Review

Diagram 558 features a simple yet unmistakable symbol of a descending aircraft inside a red-bordered triangle.
