Question 313 Rules of the Road

The correct answer is D) All of the above. This is because according to the Inland Navigation Rules, a power-driven vessel crossing a river on the Great Lakes or Western Rivers must keep out of the way of all other power-driven vessels, regardless of whether they are descending the river with a tow, ascending the river without a tow, or ascending the river with a tow. The rationale is to ensure the safety of navigation by giving priority to vessels already operating within the river system. The other options are incorrect because they only specify certain vessel types, when in fact the crossing vessel must yield to all power-driven vessels in the river.
