Question 970Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND You are underway, in fog, when you hear a whistle signal of one prolonged blast followed by two short blasts. This signal could indicate which type of vessel?
AI Explanation
The correct answer is A) Not under command.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), the signal of one prolonged blast followed by two short blasts indicates that the vessel is "not under command". This means the vessel is unable to maneuver as required by these rules and is therefore unable to keep out of the way of other vessels.
The other answer choices are incorrect because they do not match the given whistle signal. A vessel that is aground, being towed, or in another situation would have different whistle signals to indicate their status.
