What is forbidden on all ramps and vehicle service roads of this airport unless in an assigned work area?

• A. Pedestrian traffic is forbidden on all ramps and vehicle service roads of this airport unless in an assigned work area.
• B. Pedestrian traffic is allowed on ramps and vehicle service roads.
• C. Pedestrian traffic is restricted only in certain areas.
• D. Bicycles must use designated pedestrian walkways.

Answer: (A)

The main concept is safety and access control on airport ramps and service roads. These areas are high-traffic with moving aircraft, fuel and service vehicles, so pedestrian movement is tightly restricted. The rule tested says pedestrians are forbidden on all ramps and vehicle service roads unless they are in an assigned work area. This keeps non-workers out of paths where a collision or exposure to hazards could occur, ensuring smooth operations and protection for personnel.

The other options would undermine that safety requirement: allowing pedestrians generally contradicts the universal restriction, saying restrictions apply only in certain areas implies inconsistency with “on all ramps and vehicle service roads,” and bringing bicycles into the statement introduces a separate rule not addressed here.
