Question 22

The Correct Answer is A **Explanation for Option A (Correct Answer):** Option A is correct because the fundamental purpose of a Traffic Separation Zone (TSZ)—which is part of a Traffic Separation Scheme (TSS)—is defined precisely as separating streams of traffic moving in opposing directions. This is clearly stated in Rule 10 (Traffic Separation Schemes) of the International Regulations for Preventing Collisions at Sea (COLREGs), which applies to both international and inland waters when a TSS is established. The TSZ is the neutral buffer area (usually a defined zone of light blue or white on charts) positioned between the separation lanes (Traffic Lanes). **Explanation for Incorrect Options:** * **B) is located between the scheme and the nearest land:** This describes a **Coastal Traffic Zone (Inshore Traffic Zone)**, not the Traffic Separation Zone. The Coastal Traffic Zone is the area designated between the TSS and the adjacent coast (Rule 10(d)). * **C) is designated as an anchorage area:** Traffic Separation Schemes are explicitly designed to keep traffic flowing safely. While certain areas near or adjacent to a TSS might be designated for anchorage, the **Traffic Separation Zone itself** is an area that mariners are generally instructed to avoid crossing or using for non-essential purposes, and it is certainly not designated as an anchorage area. * **D) contains all the traffic moving in the same direction:** The area that contains traffic moving in the same direction is the **Traffic Lane** (or Separation Lane), not the Traffic Separation Zone. The TSZ separates these lanes.
