Question 128 Rules of the Road

The correct answer is B) The vessels may reach agreement by radiotelephone and sound no whistle signal. This is correct because under the Inland Navigation Rules, when two power-driven vessels are meeting on a river and will pass at least 1/4 mile apart, the vessels may communicate by radiotelephone and agree on the safest method of passing, without the need to exchange whistle signals. As long as the vessels can clearly see each other and reach a verbal agreement, they are not required to sound any whistle signals. The other options are incorrect because they do not align with the Inland Navigation Rules for this scenario. Options A, C, and D all prescribe the use of whistle signals, which is not necessary if the vessels can communicate by radiotelephone and agree on the passing arrangement.
