When must vehicle operators wear high visibility clothing?

The requirement for vehicle operators to wear high visibility clothing is essential for ensuring safety when they are in potentially hazardous environments, especially in an airport setting. High visibility clothing enhances the operator's visibility to both other personnel and vehicle operators, reducing the chances of accidents in high-traffic areas.

Wearing such clothing is particularly important when operators are airside, as they may interact with aircraft, ground vehicles, and other personnel in busy airport operations. It is equally crucial when the operator is away from the vehicle, as they need to be seen clearly by others who may be moving quickly or have limited visibility, such as during inclement weather or low-light conditions. This practice not only safeguards the individual wearing the clothing but also contributes to the overall safety and efficiency of airport operations.
