Question 22

The Correct Answer is A. **Explanation for Option A (Correct Answer):** Option A ("separates traffic proceeding in one direction from traffic proceeding in the opposite direction") is the correct definition of a Traffic Separation Zone (TSZ) within a Traffic Separation Scheme (TSS), according to the International Regulations for Preventing Collisions at Sea (COLREGs) and standard navigational practices. A TSZ is the designated area of water that acts as a buffer or median strip to physically separate the lanes of traffic (Traffic Separation Lanes) where vessels are proceeding in opposite or nearly opposite directions, thereby reducing the risk of head-on collisions. **Explanation for Incorrect Options:** * **Option B (is located between the scheme and the nearest land):** This describes a **Inshore Traffic Zone (ITZ)**, not the Traffic Separation Zone. The ITZ is the area of water between the landward boundary of a TSS and the adjacent coast. * **Option C (is designated as an anchorage area):** Anchorage areas are specifically designated zones for vessels to drop anchor, and they are typically positioned outside the main traffic lanes and separation zones to avoid hindering navigation. A TSZ is not an anchorage area; vessels should generally avoid anchoring within a TSZ. * **Option D (contains all the traffic moving in the same direction):** This describes a **Traffic Separation Lane (or Traffic Lane)**, not the Traffic Separation Zone. The Traffic Separation Lane is the area within which traffic moves in the designated direction. The Traffic Separation Zone separates these lanes.
