What can impair visibility while driving on the airside?

Driving on the airside requires a clear line of sight and awareness of both aerodynamic and ground conditions. Inclement weather conditions, such as fog and rain, significantly impair visibility by creating various obstacles like reduced clarity, diminished contrast, and obscured landmarks. Fog can cause thick air that limits how far a driver can see, and rain can create reflections and splashes that hinder visibility. These conditions can make it difficult for drivers to spot other vehicles, personnel, or equipment on the airfield.

While high levels of ambient light can temporarily dazzle or blind drivers, especially during sunrise or sunset, this is not typically categorized as a primary impairment of visibility like inclement weather. Similarly, while traffic congestion can lead to distractions or slower speeds, it does not directly impair visibility in the same way that weather conditions do. Hence, the most accurate hazard to visibility in this context is indeed inclement weather conditions.
