What color are the runway markings and runway hold lines?

• A. Blue
• B. Red
• C. Yellow
• D. Green

Answer: (C)

Runway markings and runway hold lines are standardized to be yellow. This color is used for several reasons related to visibility and safety. Yellow is highly visible against the background of the runway surface, making it easier for pilots and vehicle operators to identify critical instructions and boundaries during both daytime and nighttime operations. Runway hold lines, which indicate where aircraft and vehicles must stop before entering a runway, are distinctly marked in yellow with solid and broken lines. The use of yellow for these markings helps to ensure that they stand out, thereby reducing the risk of accidents. The consistency of this color across airports enhances familiarity for pilots and ground personnel, contributing to overall airfield safety and efficiency.
