Question 336 Rules of the Road

The correct answer is D) all-round white or yellow light. According to the Inland Navigation Rules, a light used to signal passing intentions must be an all-round white or yellow light. This is specified in Rule 34(c) of the Inland Navigation Rules, which states that a vessel intending to overtake another vessel shall indicate her intention by displaying an all-round white or yellow light. The other answer choices are incorrect because they do not match the specific requirement in the Inland Navigation Rules. An alternating red and yellow light (A) or an alternating white and yellow light (C) would not be the correct light to use for signaling passing intentions. An all-round white light only (B) is also not the correct light, as the rules specify that it can be either white or yellow.
