What does the light signal consisting of three flashes indicate?

The light signal consisting of three flashes is an accepted international maritime signal used to convey specific maneuvers or situations. In this case, the correct interpretation of three flashes indicates that the vessel is altering its course to port. This signaling is part of the communication protocols established to ensure safe navigation and to prevent misunderstandings between vessels on the water. Other signals such as one flash indicate altering course to starboard, while other sequences have distinct meanings for different maneuvers or statuses, but three flashes specifically aligns with altering course to port. Understanding this signaling is crucial for maintaining safety and clarity in maritime operations, as it helps vessels predict each other's movements and respond appropriately.
