BOTH INTERNATIONAL & INLAND What lights must be shown on a barge being towed astern at night?

A A white light at each corner
B Sidelights and a stern light
C A white light fore and aft
D A stern light only
AI Explanation

The correct answer is B) Sidelights and a stern light. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a barge being towed astern at night must display sidelights (red and green) and a stern light (white). This is specified in Rule 24 of the COLREGS and the corresponding Inland Navigation Rule. The other options are incorrect because they do not fully comply with the lighting requirements for a barge under tow.
