Which statement accurately describes when inland passing signals must be sounded by a power-driven vessel?

• A. Crossing less than half a mile ahead requires passing signals.
• B. Crossing more than a mile ahead requires passing signals.
• C. No passing signals are ever required.
• D. Passing signals are required only when anchored.

Answer: (A)

On inland waterways, power-driven vessels must communicate their passing intentions when the vessels are in close quarters, specifically within half a mile of each other in a crossing situation. This signal helps the other vessel understand where you plan to pass and prevents a collision as you maneuver. If you’re more than half a mile apart, there’s enough time for mutual understanding through other cues, so a formal passing signal isn’t required. The idea that signals are never required or only needed when anchored isn’t correct, and the rule is about close-range crossing situations, not distant ones.
