Which color lights indicate a taxiway?

Taxiway lights are essential for guiding aircraft safely along taxiways during both day and night operations. The correct answer, blue lights, specifically indicate the edges of taxiways. This color is used to delineate the taxiing path for aircraft, ensuring pilots can easily see where they should taxi without inadvertently straying onto runways or other non-taxiway areas.

Blue lights are strategically placed to outline the taxiway and help prevent accidents by providing clear visual cues. Using blue lighting for taxiways helps maintain a standardized visual signaling system across airfields, facilitating safer navigation for pilots operating in low visibility conditions.

In contrast, green lights are typically used for runway centerlines, guiding pilots during takeoffs and landings. Yellow lights serve as caution signals, often designating hold short lines or other important markings that require pilot attention. Red lights are generally associated with warning signals to indicate areas where aircraft should not enter, such as runway incursion zones or hazardous areas. Each color plays a distinctive role in airfield operations, and recognizing their meanings is crucial for safe airfield driving.
