Low flying aircraft or sudden aircraft noise likely ahead
A red triangle with a low-flying aircraft warns of an area where aircraft fly low — usually near military airfields or commercial airports. The hazard isn't the aircraft itself but the sudden noise, which can startle drivers and cause swerving. Stay alert and don't be distracted by looking up.
