INTERNATIONAL ONLY Which is TRUE when your vessel is moving from a berth alongside a quay (wharf)?

Correct Answer: Option D — No signal is required.

Rule 34(a) applies only when vessels are in sight of one another and are maneuvering as authorized or required by the Rules. Moving from a berth is a routine harbor maneuver not requiring a specific whistle signal under the International Regulations for Preventing Collisions at Sea.
