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). According to the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 10, a TSZ (often referred to as a separation zone or separation line) is specifically established within a Traffic Separation Scheme (TSS) to physically or conceptually divide the lanes of traffic moving in opposing directions, thereby reducing the risk of head-on collisions. This definition applies under both International and Inland rules where TSS are implemented. **Explanation for Incorrect Options:** * **Option B (is located between the scheme and the nearest land):** This describes a **Inshore Traffic Zone (ITZ)**, which is an area designated between the TSS (specifically the nearest traffic lane) and the coast, where ships can navigate outside the formal scheme. It is not the definition of a separation zone. * **Option C (is designated as an anchorage area):** Anchorage areas are specifically designated zones where vessels can stop and anchor safely. They are typically placed outside the defined traffic lanes and separation zones of a TSS, as anchoring within these areas is generally prohibited. * **Option D (contains all the traffic moving in the same direction):** This describes a **traffic lane** (or traffic proceeding direction), which is the designated area within the TSS where traffic moves in a particular direction. The Traffic Separation Zone separates these lanes, it does not contain the traffic itself.
