Which authority grants clearance to use airfield roads?

• A. Tower
• B. Security
• C. Ground control
• D. Police

Answer: (C)

Ground control oversees all movement on the airfield movement area and is the authority that issues clearances for vehicles to use airfield roads. They coordinate where aircraft and vehicles can travel to prevent conflicts, guiding you with instructions such as when to proceed, hold, or cross intersections. This role ensures safe, orderly movement on taxiways, ramps, and the roads that run through the movement area.

The tower focuses on aircraft operations on runways and in the airspace around the field, issuing takeoff and landing clearances and ensuring separation from other traffic; it doesn’t typically grant routine road usage clearance for vehicles. Security manages access to airside areas and can authorize entry or escort personnel, but the specific clearance to operate on airfield roads comes from ground control. Police handle law enforcement and incident response, not the day-to-day traffic coordination on the movement area.
