When is an information sign provided in airport taxiways and runways?

• A. An information sign is used to denote runway distance remaining.
• B. An information sign is used to identify taxiway centerlines.
• C. An information sign is used to designate prohibited areas.
• D. An information sign is provided where an intermediate holding position marking is established and there is an operational need to identify a destination, location, frequency or routing information.

Answer: (D)

Information signs provide non-operational guidance at specific points on the movement area, especially where an intermediate holding position is established and pilots need extra context to proceed. They convey destination, location, frequency, or routing information to help you navigate and coordinate with ATC beyond what pavement markings show. This is why an information sign is provided in that situation. It’s not about runway distance remaining (that uses a different sign), it isn’t for identifying taxiway centerlines (those are painted markings), and it isn’t used to designate prohibited areas (that uses other signage).
