BOTH INTERNATIONAL & INLAND What does a light signal of three flashes mean?
AI Explanation
The correct answer is C) "I am operating astern propulsion".
This signal of three flashes is used to indicate that the vessel is operating with its propulsion system in reverse or astern. This signal is required by both the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules to inform other vessels in the vicinity of the vessel's maneuvering capabilities.
The other options are incorrect because they do not accurately represent the meaning of the three-flash light signal. Option A refers to overtaking another vessel, Option B indicates uncertainty about another vessel's actions, and Option D specifically refers to the vessel's engines being in full speed astern, which is more detailed than the general "operating astern propulsion" signal.
