Who has priority on an airside road?

Aircraft always have priority over vehicles on an airside road due to safety regulations that prioritize aircraft movement. This ensures that aircraft can operate safely and efficiently without delays caused by ground vehicles. The presence of aircraft on the runway or taxiway demands that ground vehicles yield, as any interference could lead to dangerous situations or accidents.

This understanding is crucial for all personnel operating on airside environments, as it helps maintain safety and operational integrity. Vehicles must always be on the lookout for approaching aircraft and must stop or yield as necessary to allow for their movement. The other options do not align with the established safety protocols that prioritize aircraft over all other types of vehicles or personnel on the airside.
