INLAND ONLY Vessels "A" and "B" are meeting on a river as shown in illustration D029RR below and will pass 1/4 mile apart. Which statement is TRUE?

Correct Answer: Option B — The vessels may reach agreement by radiotelephone and sound no whistle signal.

33 CFR 83.14(a) (Inland Rule 14) allows vessels in a meeting situation to reach agreement via radiotelephone in lieu of sound signals. When such an agreement is reached, the requirement to sound whistle signals is waived, provided both vessels understand and comply with the agreed-upon passing arrangement.
