Rule 34 governs which type of signals?

• A. Maneuvering and warning signals
• B. Sound signals
• C. Navigation lights
• D. Right-of-way signals

Answer: (A)

Rule 34 is about signals that vessels use to communicate their movements and warnings to others. These maneuvering and warning signals tell nearby vessels what you intend to do—like changing course, altering speed, or signaling a possible danger—so everyone can adjust and avoid a collision. They’re a distinct category from navigation lights (which indicate a vessel’s status at night) and from other sound-signaling rules that come into play in restricted visibility. Understanding Rule 34 means knowing how to both send and interpret these signals to maintain safe separation on the water.
