Low-flying Aircraft

Low-flying aircraft warning signs appear on roads near airport flight paths and military airfields.

Common near Dublin Airport on approach roads along the M1 and M50, around Cork Airport on the N27, near Shannon Airport on the N19, and on roads adjacent to military airfields such as Casement Aerodrome in Dublin and Baldonnel.

Signs also appear near smaller regional airports in Kerry, Donegal, and Sligo where approach paths cross public roads.

Aircraft on approach or departure paths may pass very low overhead, creating sudden loud noise and potentially startling drivers.

Remain focused on the road and do not look up at aircraft while driving.

The noise can be intense enough to cause instinctive reactions—resist any urge to brake suddenly or swerve.

Be particularly alert for aircraft during takeoff and landing times (typically 6 AM to 11 PM at major airports).

Keep both hands on the wheel and maintain steady speed and lane position despite noise distractions.

While the sign itself creates no legal obligation, distracted driving due to aircraft watching can result in careless driving charges: 2 penalty points and fines to €2,000.

Looking up at aircraft instead of watching the road constitutes distracted driving.

If distraction causes a collision or dangerous maneuver, dangerous driving charges apply: 5 penalty points, fines to €5,000, imprisonment, and disqualification.

Maintain focus on your driving regardless of overhead distractions.

Distraction management is a core competency assessed throughout practical tests.

Examiners observe whether you maintain focus despite various distractions including loud noises, visual stimuli, or unusual events.

If low-flying aircraft pass during your test, you must demonstrate uninterrupted focus on driving tasks: steady speed, correct lane position, continuing observation, and no visible reactions to the distraction.

Looking up at aircraft results in Grade 2 faults for allowing distractions to affect driving.

Written questions test understanding that drivers must ignore non-road-related stimuli regardless of how dramatic or loud.
