What color are the lights used at the intersection of an apron and a taxiway?

• A. Red
• B. Single green
• C. Double amber
• D. Flashing white

Answer: (C)

The lights used at the intersection of an apron and a taxiway are designated by double amber lights. This color coding is a standardized visual signal indicating caution to drivers of airside vehicles. The double amber lights alert operators to be prepared to stop, as they approach a potential conflict point with taxiing aircraft. In contrast, red lights typically signal a stop situation, and while single green lights might indicate go for certain vehicle movements, they are used in different contexts. Flashing white lights are usually associated with navigational aids and may not convey the same cautionary message as the double amber lights used at these critical intersection points. Understanding these light signals is essential for maintaining safety and efficiency on the airside, especially around busy taxiways and aprons.
