BOTH INTERNATIONAL & INLAND Which vessel would exhibit sidelights when underway and not making way?

Correct Answer: Option A — A vessel towing astern

Rule 24(a) mandates that a power-driven vessel towing astern must exhibit sidelights and a stern light, regardless of whether she is making way or dead in the water. Unlike vessels restricted in their ability to maneuver, a towing vessel remains a power-driven vessel and must display sidelights while underway.
