Who has priority on the airside among aircraft, vehicles, and pedestrians?

• A. Aircraft have priority; vehicles and pedestrians must yield to moving aircraft and follow ATC instructions.
• B. Vehicles have priority over aircraft.
• C. Pedestrians have priority over aircraft.
• D. ATC has no role in priority.

Answer: (B)

On the airside, the movement of everyone and everything is coordinated to keep operations safe. The question tests who has priority when aircraft, vehicles, and pedestrians share the same space. In this context, vehicles have the priority over aircraft. This means that if a vehicle is moving or about to enter an intersection or crossing, aircraft and pedestrians should yield, slow down, or stop as needed to allow the vehicle to pass safely. The vehicle operator is responsible for maintaining visibility, using signals, and ensuring the path is clear, while ATC still provides clearances and directions for everyone. Pedestrians do not have priority over vehicles, and they should only cross where designated and with the vehicle operator’s awareness.
