Rules of the Road · Western Rivers & Great Lakes

On the Western Rivers, a descending vessel signals her intention to pass a vessel going upstream. What must the ascending vessel do?

Explanation

Because the descending vessel has the right of way under Inland Rule 9(a)(ii), she initiates the whistle signal. The ascending (give-way) vessel must wait for and respond to that signal, acknowledging the descending vessel's maneuvering proposal.

Authority: Inland Rule 9(a)(ii)
