Under all conditions, which has right-of-way over all vehicle / ground equipment?

• A. The aircraft shall have right-of-way over all vehicle/ground equipment
• B. Vehicles shall have right-of-way over aircraft
• C. Ground equipment has priority over aircraft
• D. There is no universal right-of-way

Answer: (D)

There isn’t a single universal rule about who has the right-of-way among aircraft and ground equipment at an airport. Right-of-way is determined by the active instructions of air traffic control and ground control, plus posted signs, markings, and marshal signals, and it can vary by situation. In general, aircraft have priority when they are cleared to move on runways or taxiways, and vehicles must yield to them. But ground crews can be authorized to move equipment under tow or follow a marshal’s signal, and some operations may operate under specific clearances that momentarily override other expectations. The key idea is that you must follow the controller’s directions and any signals or markings, rather than assuming a fixed priority for aircraft, vehicles, or ground equipment.
