Which is CORRECT regarding the use of a 'special flashing light'?

• A. It must be yellow in color.
• B. It must be red in color.
• C. It must be blue in color.
• D. It must be green in color.

Answer: (A)

A special flashing light is yellow. This color is used to signal that the vessel displaying it is engaged in a specialized operation (such as dredging, underwater work, or other work that may limit its ability to maneuver). Because such operations can create hazards or require other vessels to give extra room, the yellow flashing signal tells others to proceed with caution and keep a safe distance. The other colors are used for different, standard signaling purposes and do not indicate a vessel performing a special operation, which is why yellow is the correct choice.
