1. Aircraft
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.
What should an aircraft-warning sign tell drivers in South Africa?
Where an aircraft warning is installed, it alerts drivers to low-flying aircraft or sudden aircraft noise near an airfield or flight path. An aircraft pictogram, if used locally as a hazard warning, is different from a direction sign pointing to an airport. Exact warning-sign designs and placement depend on the national sign rules.

Does an aircraft warning automatically reduce the speed limit in South Africa?
No, not by itself. A hazard warning is not a numerical speed-limit sign. Obey any separately displayed speed restriction and adjust speed if actual conditions make this necessary.
What if a low-flying aircraft distracts you while driving in South Africa?
Keep your eyes on the road, maintain your lane and avoid sudden braking or steering simply to watch the aircraft. If you need to stop, find a safe and permitted stopping place.
