Question 840 Rules of the Road

The correct answer is D) A red light over a white light. According to the International Rules for the Prevention of Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel engaged in fishing, other than trawling, must display a red light over a white light at night. This configuration of lights helps identify the vessel as one engaged in fishing, rather than other types of vessels. The other options are incorrect because they do not match the required lighting configuration for a vessel engaged in fishing, other than trawling. A white light over a red light (option A), two red lights one over the other (option B), and a green light over a red light (option C) are not the correct identification lights for this type of vessel.
