Which lighting configuration indicates a barge being pushed ahead (not part of a composite unit) on inland waterways?

• A. Sidelights And A Special Flashing Light
• B. Two Towing Lights
• C. A Masthead Light And A Sidelight
• D. A Single White Light At The Stern

Answer: (A)

On inland waterways, a barge being pushed ahead that isn’t part of a composite unit is shown with sidelights plus a special flashing light. The sidelights identify the barge and its orientation, while the special flashing light specifically signals that the vessel is being pushed rather than being part of a tug-and-barge composite or being towed. This combination communicates a distinct configuration to other vessels, helping them understand how to pass safely. The other lighting patterns imply different arrangements—for example, two towing lights indicate towing a vessel, a masthead light with sidelights is the standard setup for a lone power-driven vessel, and a single white stern light does not convey the pushed-barge situation.
