Question 1002Rules of the Road90% to pass

BOTH INTERNATIONAL & INLAND While underway and towing, your vessel enters fog. Which fog signal should you sound?

AI Explanation
The correct answer is B) One prolonged blast and two short blasts. According to the Navigation Rules, International and Inland, Rule 35(c), a vessel that is towing another vessel while underway must sound "one prolonged blast followed by two short blasts at intervals of not more than 2 minutes" when operating in conditions of restricted visibility. The other options are incorrect because they do not match the specific signal required for a vessel that is towing another vessel in fog. Option A, three distinct blasts, is the signal for a vessel not under command, while options C and D are for vessels not towing.
