90% to pass

INLAND ONLY At night, a light signal consisting of two flashes by a vessel indicates __________.

A an intention to communicate over radiotelephone
B an intention to leave another vessel to starboard
C that the vessel is in distress
D an intention to leave another vessel to port
AI Explanation

The correct answer is B) an intention to leave another vessel to starboard. The Inland Navigation Rules (Rule 34) state that a vessel intending to leave another vessel to starboard should signal this by displaying two short flashes of a white light. This signifies the vessel's intention to pass the other vessel on its starboard (right) side. The other options are incorrect because A) is for radiotelephone communication, C) indicates a vessel in distress, and D) would signal the intention to pass on the port (left) side.
