Which information indicates possible traffic near the mariner's location?

• A. Presence of commercial traffic (i.e., ferries, harbor tour boats, merchant vessels, etc.)
• B. Weather conditions
• C. Engine diagnostic codes
• D. Radio frequency plan

Answer: (A)

Recognizing possible traffic near your location comes from signs that other vessels are actively operating in the area. The presence of commercial traffic—ferries, harbor tour boats, merchant vessels—directly indicates that there are other craft nearby, so you should expect crossing or converging paths and adjust your navigation, speed, and lookout accordingly. Weather conditions can affect safety and visibility, but they don’t by themselves reveal how many or which vessels are around. Engine diagnostic codes pertain to your own boat’s systems, not external traffic, and a radio frequency plan is about channels and procedures for communication, not current vessel activity. In practice, you’d monitor AIS, radar, and VHF to track the actual traffic and stay clear of conflicting movements.
