Question 672 Rules of the Road

The correct answer is A) a vessel towing. The lights shown in illustration D060RR are the required lights for a vessel that is towing another vessel or object. According to the International and Inland Navigation Rules, a vessel engaged in towing another vessel or object must display the masthead lights, sidelights, and sternlight prescribed for the vessel being towed. This configuration of lights helps to visually indicate the presence and nature of the towing operation to other vessels in the area. The other answer choices are incorrect because the lights in the illustration are not the appropriate configurations for a fishing vessel, a vessel that is broken down, or a vessel being towed.
