Why is it important for drivers to keep their vehicle's lights on while operating airside?

Keeping vehicle lights on while operating airside is essential primarily for visibility and to indicate that the vehicle is active. The airside environment can be busy and potentially hazardous, with numerous vehicles and pedestrians moving simultaneously. By having the lights on, drivers enhance their visibility to others, helping to reduce the risk of accidents.

It also serves as a signal to other operators and personnel that the vehicle is in use, which is critical in a dynamic setting like an airport where clear communication and visibility help maintain safety protocols and prevent collisions.

In contrast, options suggesting compliance with vehicle maintenance guidelines, signaling for assistance, or saving battery life in the daytime do not directly address the immediate safety concerns that are paramount in the airside environment. Making lights a standard practice is a key component of ensuring operational safety in such a high-traffic area.
