Question 378 Deck Safety

70% to pass

Which one of the following signals is made at night by a lifesaving station to indicate "Landing here highly dangerous"?

A White star rocket
B Horizontal motion of a white light or flare
C Vertical motion of a white light or flare
D Vertical motion of a red light or flare
AI Explanation

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.
