What requirement must all baggage or cargo carts fulfill?

Baggage or cargo carts are required to have at least two reflectors or fluorescent tape on each side and rear of the vehicle to enhance their visibility, particularly in low-light conditions or when they are not in direct line of sight. This requirement is crucial for the safety of the airport environment, as it helps reduce the risk of accidents involving moving vehicles, personnel, and aircraft. The visibility enhancements ensure that baggage carts are easily seen by both drivers and pedestrians, particularly in busy areas of the airport.

Other requirements, while important, do not specifically emphasize the critical aspect of visibility in the same manner as the reflectors or tape, which play a key role in maintaining safe operations within the airport's confined and fast-paced environment.
