What must a driver wear while operating a vehicle on the airfield?

A safety vest is essential for drivers operating vehicles on the airfield because it significantly enhances visibility. The airside environment can be busy and chaotic, with various moving vehicles and aircraft, making it crucial for operators to be easily seen by others. Wearing a safety vest helps ensure that all personnel, including ground crew and pilots, can clearly identify vehicle operators, thus reducing the risk of accidents.

In addition to promoting visibility, safety vests often reflect light, making them effective in low-visibility conditions, such as during dawn, dusk, or inclement weather. This reflective quality is critical for maintaining a safe airfield where both drivers and pedestrians are present.

While helmets and goggles provide protection in some environments, they are not standard requirements for airfield vehicle operation, and high-visibility jackets may not meet the specific regulations set forth for airside operations. The primary focus in this context is on visibility to ensure a safe working environment, making the safety vest the most appropriate choice for this situation.
