What is the purpose of zipper lines in an airport environment?

The purpose of zipper lines in an airport environment is primarily to warn drivers of potential crossings. Zipper lines are designed as visual cues to alert vehicle operators about areas where they should be cautious, as other vehicles or aircraft may be crossing nearby. These lines help in maintaining safety by clearly indicating where the right of way should be observed, promoting awareness and encouraging drivers to slow down and be vigilant.

While designated vehicle parking areas, maintenance zones, and taxiway boundaries are marked by other specific types of lines or signage, zipper lines serve the unique function of enhancing safety by ensuring that drivers are cautious at critical crossing points. This yellow marking, resembling a zipper, effectively communicates potential hazards to vehicle operators navigating the airside areas of the airport.
