Which vehicle operation is prohibited on active runways?

The operation of civilian vehicles on active runways is prohibited primarily due to safety and security reasons. Active runways are critical areas where aircraft are taking off and landing, and any vehicle that is not part of the airport operation can pose significant risks. Civilian vehicles lack the necessary communication protocols and awareness related to air traffic control that ensure safe operations on an active runway.

In contrast, emergency response vehicles, taxiing aircraft, and military transport vehicles may operate on runways under specific conditions and regulations set by the airfield authorities. Emergency response vehicles are equipped to respond quickly to incidents, and their operation may be vital during emergencies. Taxiing aircraft are essential to the flow of air traffic as they maneuver between the runway and terminal or other areas of the airfield. Additionally, military transport vehicles can also operate under circumstances dictated by military procedures and coordination with air traffic control.

Thus, the prohibition of civilian vehicle operations on active runways is crucial for maintaining a safe airfield environment.
