Question 506 Rules of the Road

The correct answer is A) when underway and making way. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel engaged in fishing, regardless of whether it is in international or inland waters, is required to exhibit sidelights (red and green) and a stern light when it is underway and making way through the water. This is specified in Rule 26 of the COLREGS. The other answer choices are incorrect because: B) a vessel at anchor is not required to show sidelights and a stern light, C) a vessel is only required to show these lights when underway, not just if underway, and D) a vessel that is dead in the water is not considered to be underway and making way.
