Question 622 Rules of the Road

The correct answer is C) a vessel restricted in her ability to maneuver and not making way. This is correct because the lights shown in illustration D057RR depict the lights required for a vessel restricted in her ability to maneuver, as per the International Regulations for Preventing Collisions at Sea (COLREGS). These vessels are required to display three all-round lights in a vertical line, with the highest and lowest being red and the middle one being white, which is exactly what is shown in the illustration. The other options are incorrect because they do not match the light configuration shown. A pilot vessel would display different lights, a towing vessel would have different light arrangements, and a fishing vessel would not display the vertical three-light pattern.
