Question 22

The Correct Answer is A **Explanation for A (Correct Option):** Option A ("separates traffic proceeding in one direction from traffic proceeding in the opposite direction") is the internationally accepted definition and primary function of a Traffic Separation Zone (TSZ) within a Traffic Separation Scheme (TSS). A TSZ is a delineated area, often a neutral or buffer zone, used to physically and legally separate lanes of traffic moving in contra-directions, minimizing the risk of head-on collisions in congested waterways, as defined by Rule 10 of the COLREGs (International Regulations for Preventing Collisions at Sea). **Explanation for Incorrect Options:** * **B) is located between the scheme and the nearest land:** This describes a **Coastal Traffic Zone** (or inshore traffic zone), not the Traffic Separation Zone itself. The TSZ separates the traffic lanes, not the scheme from the coastline. * **C) is designated as an anchorage area:** Traffic Separation Schemes generally discourage or prohibit anchoring within the traffic lanes and the separation zone, except in emergencies. Anchorage areas are designated separately, usually outside the TSS. * **D) contains all the traffic moving in the same direction:** The area that contains all traffic moving in the same direction is the **traffic lane** or "traffic separation lane." The Traffic Separation Zone (TSZ) is the area *between* two traffic lanes moving in opposite directions.
