Question 431Rules of the Road90% to pass
INTERNATIONAL ONLY Which light(s) will a 20-meter power-driven vessel pushing ahead or towing alongside display?
AI Explanation
The correct answer is D) Two masthead lights in a vertical line.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a power-driven vessel of 20 meters or more in length, when pushing ahead or towing alongside, must display two masthead lights in a vertical line. This configuration helps identify the vessel as a power-driven vessel engaged in pushing or towing activities.
The other options are incorrect because: A) Red lights are not used for this situation, B) A single white light forward is for a vessel under sail, not a power-driven vessel, and C) Two towing lights in a vertical line are used for vessels being towed, not the vessel doing the towing.
