Question 561 Rules of the Road

The correct answer is D) Red-white-red lights in a vertical line for a carrier, launching aircraft. This is the correct answer because the U.S. Coast Guard recognizes these red-white-red vertical lights as an additional navigational light authorized by the Secretary of the Navy for ships of war, specifically aircraft carriers during flight operations. The other options are not authorized navigational lights for this purpose. The other options are incorrect because: A) Intermittent flashing amber is not an authorized light signal, B) a beacon for submarines is not a surface ship navigational light, and C) green masthead and yardarm lights indicate mineclearance operations, not specifically a ship of war.
