Why must vehicles be equipped with safety lights when operating airside at YVR?

Vehicles operating airside at YVR must be equipped with safety lights primarily to enhance visibility and ensure safety during operations. The airside environment is busy and often includes aircraft, maintenance crews, and other vehicles, all of which require clear and effective communication for safe movement. Safety lights help to alert other personnel to the presence of the vehicle, especially in low visibility conditions such as fog, rain, or at night.

By using safety lights, the risk of accidents is significantly reduced because they make vehicles more noticeable, allowing other operators and ground staff to be aware of their surroundings. This is particularly critical in an airport setting where the safety of both personnel and aircraft is paramount, and miscommunication or lack of visibility can lead to serious incidents.

The other options hint at benefits that do not align with the core purpose of these safety lights in an operational context.
