BOTH INTERNATIONAL & INLAND Which vessel must exhibit three white masthead lights in a vertical line?
AI Explanation
The correct answer is B) A vessel whose tow exceeds 200 meters astern.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel whose tow exceeds 200 meters in length must exhibit three white masthead lights in a vertical line. This is to make the vessel's size and status as a towing vessel clearly visible to other vessels in the area. The other answer choices do not accurately describe the requirement for three masthead lights in a vertical line.
