Question 643 Rules of the Road

The correct answer is C) each barge in the tow must be lighted. According to the US Coast Guard regulations, when towing barges at night, each barge in the tow must display the required navigation lights, regardless of whether the barges are manned or unmanned. This ensures that the entire tow is clearly visible to other vessels in the area, promoting safe navigation. The other answer choices are incorrect because they do not fully meet the regulatory requirements for lighting all barges in a tow at night.
