Question 339 Rules of the Road

The correct answer is D) All of the above. For inland navigation, the light used for maneuvering signals must be an all-round white or yellow light, and it must be synchronized with the whistle. This is in accordance with the Inland Navigation Rules, which specify the requirements for these maneuvering signals. The other options are incorrect because they do not fully capture the regulatory requirements. Option A is incomplete, as the light must be white or yellow, not just any all-round light. Option B is also incomplete, as the light must be an all-round light, not just any white or yellow light. Option C is incorrect, as the light must be synchronized with the whistle, not just the whistle.
