Question 22

The Correct Answer is A **Explanation for Option A (Correct Answer):** A Traffic Separation Zone (TSZ) is a fundamental component of a Traffic Separation Scheme (TSS), as defined by both the International Regulations for Preventing Collisions at Sea (COLREGs) and national/inland regulations. Its primary function is clearly established in Rule 10 (Traffic Separation Schemes) of COLREGs. Specifically, a TSZ is the area of water that physically **separates traffic proceeding in one direction from traffic proceeding in the opposite direction**. It is typically a neutral, non-navigable zone (or a zone where transit is discouraged, reserved for emergencies, or used by vessels crossing the scheme) designed to minimize the risk of head-on collisions within the scheme. **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 (TSZ). The ITZ is the navigable area between the inner boundary of the TSS and the adjacent coast. **Option C) is designated as an anchorage area** TSS lanes and separation zones are areas where vessels should maintain course and speed and avoid anchoring, except in emergencies. Anchorage areas are designated separately, usually outside the main flow of traffic. **Option D) contains all the traffic moving in the same direction** This describes the **traffic lane** itself, which is the area within the scheme designated for the flow of traffic traveling in a particular, single direction. The TSZ *separates* these lanes, it does not *contain* the unidirectional traffic.
