How should you manage speed on aprons and taxiways?

• A. Always travel at maximum allowed speed.
• B. Stop before every taxiway intersection.
• C. Increase speed to pass other vehicles.
• D. Maintain slow, controlled speed appropriate to conditions and traffic.

Answer: (D)

On aprons and taxiways, you must keep a slow, controlled speed and adjust it to what you’re seeing and hearing around you. This lets you react to pedestrians, other ground vehicles, and aircraft moving in or across your path, and to stop safely if something unexpected happens. Slow, deliberate progress is essential because surfaces can be slick, jet blast or wing tips can create hazards, and visibility can be limited in busy areas. Driving at maximum speed would reduce your ability to stop in time, and stopping at every taxiway intersection or trying to speed past other vehicles creates its own risks and disrupts operations.
