Vehicles will not be driven at what angle across parking aprons or ramps?

Driving vehicles at a 90-degree angle across parking aprons or ramps is prohibited primarily due to safety concerns and operational efficiency. A 90-degree angle involves a direct perpendicular crossing, which increases the risk of a collision with other moving vehicles or equipment that may not be clearly visible. This position can also hinder the flow of both vehicle and pedestrian traffic, creating potential hazards.

In addition, when vehicles are parked or maneuvered at sharp angles, it can obstruct the line of sight for both drivers and ground personnel, making it difficult to spot other vehicles or individuals nearby. Upholding safe driving practices within airfield environments is crucial, as these areas often involve significant ground operations and the coordination of various aircraft movements. Thus, avoiding driving at a 90-degree angle helps maintain safety standards and operational effectiveness.
