Question 873 Rules of the Road

The correct answer is D) All of the above. When a vessel is towing astern and both the towing vessel and her tow are severely restricted in their ability to change course, the towing vessel will show the following light configuration: - Sidelights - Stern light - Towing light This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS), which require these specific lights to be displayed by a vessel that is severely restricted in its ability to maneuver. The other options are incorrect because they do not fully encompass the required light configuration. Option B only mentions the masthead lights, while option C refers to the lights for a vessel restricted in its ability to maneuver, which is not the complete set of lights required for a towing vessel in this situation.
