In inland waters, vessels pushing ahead must display how many towing lights?

In the context of vessels navigating inland waters, when a vessel is engaged in pushing ahead, it is required to display two towing lights. This regulation stems from the need for clear communication of the vessel's maneuverability to other waterway users. The two towing lights should be positioned at the forward part of the vessel, indicating that it is either towing another vessel or pushing ahead. This signaling is vital for maintaining safety and avoiding collisions, especially in environments where visibility can vary and multiple vessels operate in close proximity.

Displaying two towing lights serves to identify the vessel's status and actions to other mariners, ensuring that there is no confusion regarding its operation. The other options—one towing light, no towing lights, or three towing lights—do not align with the established regulations for vessels operating in this capacity on inland waters. Adhering to these requirements is essential for safe navigational practices.
