Question 378 Deck Safety

The correct answer is B) Horizontal motion of a white light or flare. This signal is used by lifesaving stations at night to indicate that landing at that location is highly dangerous. The horizontal motion of a white light or flare conveys this warning message to approaching vessels or aircraft. The other options are incorrect because: A) a white star rocket is not the signal used for this purpose, C) a vertical motion of a white light or flare does not have the same meaning, and D) a vertical motion of a red light or flare would typically indicate a distress signal, not a warning about dangerous landing conditions.
