In which area do additional vehicle rules apply due to lack of vehicle corridors?

The correct answer is related to the Horseshoe area because it is a unique and congested location at the airport where regular vehicle corridors are not established. This means that specific additional vehicle rules are implemented to enhance safety and ensure the efficient movement of ground services, emergency vehicles, and other personnel in that high-traffic region.

In the Horseshoe, the absence of designated vehicle corridors requires drivers to exercise heightened awareness and compliance with additional protocols to navigate safely amidst various ongoing operations. This reflects the airport's commitment to maintaining operational safety in areas where typical traffic patterns do not apply, thus preventing accidents and ensuring the smooth conduct of airport activities.

On the other hand, the runway centerline, control tower, and taxiway areas either have established corridors or specific operational practices that centralize traffic flow and communication, which do not necessitate the same additional rules as found in the Horseshoe.
