Question 130 Rules of the Road

The correct answer is B) Two unobstructed all-round white lights. According to the Inland Navigation Rules, barges moored in a group formation more than two barges wide must display two unobstructed all-round white lights at night. This requirement is outlined in Rule 30(e) of the Inland Navigation Rules, which specifies the lighting requirements for barges at anchor or moored. The other answer choices are incorrect because they do not align with the Inland Navigation Rules. Option A (two unobstructed all-round red lights) is incorrect, as red lights are not the required color. Option C (two yellow lights in a vertical line) is incorrect, as the rules specify white lights. Option D (all-round yellow lights) is also incorrect, as the rules call for white lights specifically.
