Question 943Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND A power-driven vessel underway in fog making NO way must sound which signal?
AI Explanation
The correct answer is B) Two prolonged blasts.
According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a power-driven vessel underway in fog and making no way (not making any headway) must sound the signal of two prolonged blasts at intervals not exceeding 2 minutes. This signals to other vessels in the area that the vessel is underway but not under command.
The other options are incorrect because: A) One prolonged and two short blasts is the signal for a vessel not under command, B) One long blast is the signal for a vessel at anchor, and D) One prolonged blast is the signal for a vessel towing another vessel.
