An all-round flashing yellow light may be exhibited by a(n) __________.

• A. Air cushion vessel
• B. Fishing vessel
• C. Power-driven vessel
• D. Sailboat

Answer: (A)

Special signaling lights are used to convey status beyond normal navigation lights. An all-round flashing yellow light is a signal reserved for certain vessel types or operations to ensure visibility from all directions. Among the given options, air cushion vessels (hovercraft) are the ones for which this signal is specified. Their ability to move quickly across both water and land and their unusual maneuvering require a distinctive warning light so other vessels can recognize and anticipate their presence and actions, especially in restricted visibility. The other vessel types—fishing vessel, power-driven vessel, and sailboat—rely on the standard navigation lights for underway status and do not typically use a flashing yellow all-round light in ordinary operation, so they don’t fit the scenario described.
