Which vehicle is allowed to use the taxiway when not yielding to taxiing aircraft?

The correct response is that no vehicles are allowed to use the taxiway when not yielding to taxiing aircraft. This standard promotes safety on the airfield by ensuring that the movement areas remain clear for aircraft operations. Taxiways are critical pathways for aircraft to move to and from runways, and the presence of any vehicular traffic that does not yield can create hazards and increase the risk of accidents.

All vehicles must maintain a heightened awareness of their responsibilities within the airfield environment, particularly regarding the prioritization of aircraft. Any vehicle operating on or near taxiways must yield to all aircraft, as aircraft have the right of way at all times. This protocol is essential for ensuring the safety of both the vehicles and the aircraft in flight operations. By adhering to this rule, airfield personnel contribute to the overall safety and efficiency of the airfield operations.
