Question 27 Rules of the Road

The correct answer is C) Two towing lights. According to the navigation rules for inland waterways, when a tug is pushing a barge ahead at night and it is not a composite unit, the tug must display two towing lights over the stern of the barge. This is required by Rule 24(c) of the Inland Navigation Rules. The two towing lights help identify the towing configuration and provide additional visibility for the overall size and shape of the tow. The other options are incorrect because: A) a single towing light over the stern light is not the required configuration, B) two red lights would not be the proper color for towing lights, and D) a white stern light alone would not be sufficient to indicate the towing arrangement.
