Question 837 Rules of the Road

The correct answer is D) All fishing vessels that are not making way. According to the International Regulations for Preventing Collisions at Sea (COLREGS), fishing vessels that are not making way through the water are required to turn off their sidelights. This is specified in Rule 26(c) of the COLREGS, which states that "A vessel engaged in fishing, whether underway or at anchor, shall exhibit only the lights and shapes prescribed in this Rule." The other answer choices are incorrect because they do not accurately reflect the COLREGS requirements. Vessels engaged in underwater operations, sailing vessels that are becalmed, and vessels that are not under command have different lighting requirements that do not involve turning off sidelights.
