Which type of vehicles are not authorized on the airfield?

Motorcycles are generally not authorized on the airfield due to safety and operational considerations. Their smaller size and maneuverability can pose risks in environments where larger vehicles are in operation or where precise movement is crucial for airfield traffic control. Moreover, motorcycles can be less stable than other types of vehicles, leading to potential accidents, especially on runways and taxiways.

In contrast, government-owned vehicles and privately owned vehicles are often permitted under specific regulations, provided they meet safety standards and are driven by authorized personnel. All-terrain vehicles, while potentially restricted, may have specific permissions for use in particular scenarios, such as maintenance tasks or emergency response. The regulations surrounding the use of vehicles on the airfield prioritize safety and operational integrity, making the restriction on motorcycles particularly important.
