INLAND ONLY You are meeting "head on" a tug towing a barge alongside about a mile away. In addition to the white masthead lights which other lights do you see on the tug and tow combined?

Correct Answer: Option C — The green and red sidelights marking each vessel and a special flashing light

Under Rule 24, a towing vessel exhibits masthead lights indicating tow status, sidelights, a sternlight, and a yellow towing light situated above the sternlight.
