Question 36 GLI05 - Master or Mate of LT 200 GRT

The Correct Answer is A. **Explanation for Option A (Correct Answer):** In the **Inland** Rules of the Road (33 CFR Subchapter E, Inland Navigational Rules), Rule 34(c) governs signals used by the vessel being overtaken (the "privileged vessel" in the passing situation). When a power-driven vessel is being overtaken and the overtaking vessel proposes to pass on the privileged vessel's starboard side (signaled by **one short blast**), the privileged vessel must indicate agreement by sounding **one short blast**. This signal confirms that the vessel being overtaken agrees to the maneuver and understands the intention to pass on its starboard side. --- **Explanation for Incorrect Options:** **B) one prolonged, one short, one prolonged, and one short blast in that order:** This sequence is the **Danger Signal (five or more short blasts)** used in the Western Rivers, or, more commonly, the **Agreement Signal** used in the **International** Rules (COLREGs) when vessels are in sight of one another. Since the question specifies "INLAND ONLY," the International rule (Rule 34(c)(i)) signal of agreement is irrelevant and incorrect for this scenario. **C) two prolonged blasts:** A prolonged blast (4-6 seconds) is typically used for warning or indicating position (e.g., coming around a bend). Two prolonged blasts are not the prescribed signal for agreement in a standard Inland overtaking situation. **D) two prolonged followed by two short blasts:** This is the prescribed signal for a vessel being pushed ahead or towed in the Inland Rules (Rule 34(a)(iii)) or the general signal used to indicate an intention to pass on the **port** side of the overtaken vessel (two short blasts) in the International Rules, but it is not the agreement signal. Furthermore, two short blasts are the Inland signal of agreement when the overtaking vessel has proposed to pass on the **port** side, not the starboard side.
