In inland navigation, when you are being overtaken, what signal should you respond with to indicate the overtaking vessel may pass?

• A. No, you may not overtake.
• B. Yes, vessel may overtake.
• C. Repeat the signal.
• D. You should speed up.

Answer: (B)

When being overtaken, you need to give a clear confirmation that the overtaking vessel may pass. Saying “Yes, vessel may overtake” communicates explicitly that there is safe room and permission for the other boat to maneuver past you. This positive acknowledgment helps prevent confusion in crowded or narrow inland channels, where precise, predictable actions are essential for safety. Once you indicate you’re allowing the pass, the overtaking vessel will proceed to pass on the indicated side while you maintain your course and speed, staying vigilant for any changes. Other responses would either block the maneuver, ask for a repeat signal, or suggest speeding up, which could create a collision risk or confusion.
