What type of sign provides directional guidance on a taxiway?

The reason this answer is correct is that a taxiway direction sign is specifically designed to provide pilots with information regarding which direction to take as they navigate along the taxiway system of an airport. These signs typically feature arrows indicating the direction to various taxiways, ensuring that pilots are informed and can safely maneuver their aircraft.

In contrast, other types of signs have different functions. A runway location sign identifies a specific runway or its location relative to the taxiway, but it does not offer directional guidance for movement along the taxiways. Information signs provide general information about the airport or its services, such as location of facilities, but they do not instruct on directional movement. Regulatory signs communicate specific rules or restrictions, such as "Do Not Enter" or "Hold Short," and are not intended to guide pilots along taxiways in terms of directional navigation.
