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.

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.
