Question 846 Rules of the Road

The correct answer is C) a green light over a white light. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel engaged in trawling, which includes dragging a net for the purpose of catching fish, is required to exhibit a green light over a white light. This signifies that the vessel is restricted in its ability to maneuver and other vessels should give it a wide berth. The other answer choices are incorrect because they do not match the COLREGS requirements for a vessel engaged in trawling. A white over red light (A) and a red over white light (D) are for different types of vessels, while two red lights in a vertical line (B) is the correct lighting for a vessel not under command.
