What does a yellow line with a black triangle at the end signify?

The yellow line with a black triangle at the end serves as an indication of a gate number. This marking is used in airport environments to provide clear and visual cues for both pilots and ground vehicles regarding the location of specific gates. The distinct shape of the black triangle at the end of the line emphasizes the importance of that direction, ensuring that operators can navigate toward the correct gate efficiently.

Proper identification of gate numbers is crucial for coordinating the movement of aircraft and vehicles, facilitating smooth operational flow, and enhancing safety on the airside where high traffic of aircraft and service vehicles occurs. Understanding these markings is vital for anyone operating on the airside to ensure compliance with airport regulations and protocols.
