Question 105 Rules of the Road

The correct answer is C) Two unobstructed all-round white lights. According to the Inland Navigation Rules, a moored barge that reduces the navigable width of a channel to less than 80 meters is required to display two unobstructed all-round white lights at night, one at each corner of the barge farthest from the bank. This ensures that the barge is clearly visible to other vessels navigating the channel. The other options are incorrect because: A) a red light is not the appropriate color for this situation, B) yellow lights are not required, and D) four red lights would not provide the necessary visibility.
