Direction signs are characterized by which color combination?

• A. Red background with white inscription.
• B. Yellow background with black inscription.
• C. Black background with yellow inscription.
• D. White background with black inscription.

Answer: (B)

Airfield sign color coding helps pilots and ground personnel identify sign types at a glance. Direction signs use a yellow background with black inscription because the bright yellow stands out against pavement, and the black lettering remains highly legible from taxiing distances and under varying lighting. This combination is distinct from other signs: red with white letters indicate mandatory instructions, black with yellow letters indicate location on the field, and white with black letters provide general information. On direction signs you’ll often see arrows guiding you toward runways, terminals, or facilities, helping you navigate taxi routes quickly and safely.
