🔍 Key Concepts

• Inland Navigation Rule 34 (Manoeuvring and Warning Signals) – focus on the Inland-only language about when sound signals are required • The meaning of meeting, crossing, and overtaking situations when vessels are in sight of one another • The specific distance condition that triggers required whistle maneuvering signals on Inland waters

đź’­ Think About

• Look at the answer choices and ask: which one describes a situation where sound signals are required by rule, not just optional or based on convenience? • Consider whether radio agreements can ever replace whistle signals under the Inland Rules, or if the whistle requirement still applies in certain situations. • Think carefully about whether the rule is triggered by “doubt,” by “course changes,” or by a specific range between the vessels.

âś… Before You Answer

• Verify the exact Inland wording: when power-driven vessels are meeting or crossing within a certain distance, they shall exchange whistle signals. • Check whether the rule mentions VHF radio as a substitute for whistle signals, or whether the whistle signals are still required. • Confirm that the trigger in the rule is not “whenever there is doubt” but a combination of being in sight of one another and within a defined distance.
