Question 615 Rules of the Road

The correct answer is C) when making way at night, two all-round red lights, sidelights, and a stern light. This is the correct answer because the International Regulations for Preventing Collisions at Sea (COLREGS) state that a vessel which is unable to maneuver due to some exceptional circumstance must exhibit, when making way at night, two all-round red lights in a vertical line, sidelights, and a stern light. The other options are incorrect because they do not accurately describe the lighting and shape requirements for a vessel that is unable to maneuver. Option A describes the daytime shapes for a vessel restricted in its ability to maneuver, while options B and D describe the lighting requirements for vessels that are not specifically unable to maneuver.
