What area on the movement surface is an established route reserved exclusively for vehicle use?

• A. Circle of Safety
• B. Vehicle Service Road
• C. Emergency Response Vehicle
• D. ILS Critical Area

Answer: (B)

On the movement surface, there are designated routes that are reserved specifically for vehicles to move around the airport without mixing with aircraft traffic. This helps keep aircraft operations safe and orderly by giving ground vehicles a clear path separate from taxiways and runways. The established route that fits this description is the Vehicle Service Road. It is marked and intended exclusively for vehicle use, such as service, maintenance, fueling, and other ground support activities, ensuring aircraft have the clear space they need.

The other options refer to concepts or roles rather than a dedicated vehicle route. The Circle of Safety describes the protective area around a taxiing aircraft, not a roadway. An Emergency Response Vehicle is a type of vehicle, not an area. The ILS Critical Area is a restricted zone around the instrument landing system to protect its signals, not a route for vehicles.
