Question 353 Rules of the Road

The correct answer is D) "I intend to leave you on my port side." Under the Inland Navigation Rules, a one short blast signal is used to indicate that the vessel is altering its course to the starboard side, intending to leave the other vessel on its port side. This is in accordance with Rule 34(a) of the Inland Navigation Rules, which states that "When vessels are in sight of one another, a power-driven vessel underway, when maneuvering as authorized or required by these Rules, shall indicate that maneuver by the following signals on her whistle: one short blast to mean 'I am altering my course to starboard'." The other options are incorrect because they do not accurately reflect the meaning of a one short blast signal under the Inland Navigation Rules. Options A and C refer to turning to port or starboard, respectively, which is not the correct interpretation of the one short blast signal.
