Question 318 Rules of the Road

The correct answer is A) A seaplane on the water. Inland-only yellow lights are not used to identify seaplanes on the water. Seaplanes on the water are required to display the same navigation lights as other powered vessels, which typically include red and green sidelights and a white masthead light, but do not include yellow lights. The other options are incorrect because inland-only yellow lights are used to identify purse seiners, dredge pipelines on a trestle, and the heads of tows being pushed ahead by tugboats, as per the rules and regulations governing the use of navigation lights on vessels.
