What specific rule should be adhered to when driving in low-light conditions on the airside?

When driving in low-light conditions on the airside, it is essential to use headlights and remain extra vigilant for hazards. Utilizing headlights enhances visibility, allowing the driver to see better and be seen by others, which is crucial for safety in potentially chaotic airside environments. Being extra vigilant means paying closer attention to the surroundings, as low-light conditions can obscure obstacles, other vehicles, or pedestrians.

In contrast, using high beams at all times is not advisable, as this can create glare that may impair the vision of other drivers. Reducing speed only when other vehicles are present overlooks the fact that low light can obscure other risks, such as wildlife or maintenance equipment, necessitating a cautious approach at all times. Lastly, while using hazard lights might alert others to a stationary vehicle or one in distress, it is not a suitable safety measure for general low-light driving since it does not contribute to improved visibility or awareness of the surroundings. Thus, the focus on using headlights and heightened vigilance effectively promotes safety in low-light conditions on the airside.
