Question 974 Rules of the Road

The correct answer is D) One prolonged and two short blasts every two minutes. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel towing another vessel in fog is required to sound one prolonged blast followed by two short blasts every two minutes. This signal helps to identify the vessel as one that is towing another, allowing other vessels in the vicinity to be aware of its presence and potential maneuvering limitations. The other options are incorrect because they do not accurately reflect the signal required for a vessel towing in fog. Option A specifies a different interval, Option B specifies a different blast pattern, and Option C specifies a different blast pattern and interval.
