Question 491 Rules of the Road

The correct answer is A) A red light over a white light. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel underway but not making way and engaged in fishing, other than trawling, is required to display a red light over a white light. This configuration of lights indicates the vessel's status as a fishing vessel, allowing other vessels to identify it and take appropriate actions to avoid a collision. The other answer choices are incorrect because they do not accurately represent the lighting requirements for a vessel in this specific situation. For example, options B and D include additional lights like sidelights and a stern light, which are not necessary for a vessel engaged in fishing, other than trawling, and not making way.
