Question 842 Rules of the Road

The correct answer is B) green light over a white light. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel engaged in trawling, which includes fishing with nets or lines, must display a green light over a white light. This configuration of lights identifies the vessel as engaged in fishing and helps other vessels determine its course and activity. The other answer choices are incorrect because they do not match the required light configuration for a vessel trawling. A white over green light, a red over white light, or a yellow over red light would not correctly identify the vessel as engaged in trawling activities.
