Question 325 Rules of the Road

The correct answer is A) Sidelights and a special flashing light. For a barge being pushed ahead, not being part of a composite unit in inland waters, the required lights are sidelights (red and green) to indicate the vessel's direction, and a special flashing light (white) to indicate the barge is being pushed. This is in accordance with the Inland Navigation Rules, which specify the lighting requirements for barges not being part of a composite unit. The other options are incorrect because they either include unnecessary lights (B and C) or do not include the required special flashing light (D).
