Core facts about Low-flying Aircraft
Sign name	Low-flying Aircraft
Sign type	Warning Signs
Expected in DTT?	Yes. This sign is commonly covered in Irish driving theory test preparation.
Action required	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.
Appearance	Triangular / Red and white
Typical location	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.

Appears in Driving Test?

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.
