Question 592 Rules of the Road

The correct answer is D) All of the above. A vessel towing astern is considered a "vessel restricted in its ability to maneuver" under both the International and Inland Navigation Rules. As such, it must exhibit the following lights: the masthead lights for a towing vessel (option A), sidelights, stern light and towing light (option B), as well as the lights for a vessel restricted in its ability to maneuver (option C). This comprehensive set of lights is required to clearly signal the vessel's restricted maneuvering capabilities to other ships in the vicinity. The other options are incorrect because they do not fully encompass the lighting requirements for a vessel towing astern. Option A only covers the masthead lights, while option B and C do not include all the necessary lights.
