What must vehicles never drive over?

Vehicles must never drive over hoses, cables, or cords due to safety concerns. These items are essential for various operations at the airport, including fueling, ground power, or other maintenance activities. Running over them could damage the hoses or cables, leading to potential hazards such as fuel spills or electrical failures. Additionally, it poses risks to personnel who may be working in those areas, as their safety could be compromised if equipment is damaged or becomes inoperable.

Driving over hoses and cables can also cause interference with the proper functioning of airport operations, which relies on these systems being intact and undisturbed. By avoiding driving over them, vehicle operators help maintain a safe and efficient airside environment.
