Question 1012Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND While underway in fog, you hear a vessel sound four short blasts in succession. What does this signal indicate?
AI Explanation
The correct answer is D) A pilot vessel on duty.
The International Regulations for Preventing Collisions at Sea (COLREGS) state that a pilot vessel on duty will sound four short blasts in succession to indicate its presence. This signal is used to alert other vessels in the area that a pilot vessel is operating and caution them to proceed with extra care.
The other answer choices are incorrect because they do not match the COLREGS requirement for a pilot vessel's sound signal. A vessel fishing, a sailboat on port tack, and a vessel being towed would each have different sound signals according to the COLREGS.
