Question 854 Rules of the Road

The correct answer is B) not under command. The lights shown in illustration D083RR depict the lights required for a vessel that is not under command, meaning the vessel is unable to maneuver as required by the International Regulations for Preventing Collisions at Sea (COLREGS). This includes vessels that are disabled, anchored, or aground. The all-round red light and the two all-round white lights are the characteristic lights for a vessel not under command. The other answer choices are incorrect because they do not accurately describe the lighting configuration shown in the illustration. A fishing vessel would exhibit different lights, a towing vessel would have different lighting, and a vessel being towed would also have a different lighting arrangement.
