An aircraft warning is a traffic warning indicating that aircraft may pass at low altitude above or close to the road, usually near an airport, airfield or flight path. The warning is intended to prepare drivers for the sudden appearance or noise of low-flying aircraft.

Drivers should remain focused on the road and avoid sudden braking or steering movements if an aircraft passes overhead. The design and use of aircraft warning signs vary between countries.
