Question 429Rules of the Road90% to pass
INTERNATIONAL ONLY A power-driven vessel pushing ahead or towing alongside will show sidelights, a stern light, and which additional light(s)?
AI Explanation
The correct answer is B) Two masthead lights in a vertical line.
The International Regulations for Preventing Collisions at Sea (COLREGS) state that a power-driven vessel pushing ahead or towing alongside must show sidelights, a stern light, and two masthead lights in a vertical line. This is specified in Rule 23(a) of the COLREGS.
The other answer choices are incorrect because: A) a single white light forward is not the correct configuration, C) two yellow masthead lights is not the requirement, and D) an all-round red light is not the correct light for this type of vessel.
