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 correct because it provides the official definition and primary function of a Traffic Separation Zone (TSZ) as defined under both the International Regulations for Preventing Collisions at Sea (COLREGs) and Inland Rules. A TSZ is an area within a Traffic Separation Scheme (TSS) specifically designated to physically or spatially separate lanes of traffic moving in opposing 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 **Coastal Traffic Zone** or, more commonly, the area between the TSS and the coast, often referred to as a separation zone from the scheme itself, but it is not the definition of the central Traffic Separation Zone. * **Option C (is designated as an anchorage area):** Traffic Separation Zones are generally prohibited areas for anchoring and navigation, except in emergencies. Anchorage areas are designated separately, outside the main traffic lanes and separation zones. * **Option D (contains all the traffic moving in the same direction):** This describes a **Traffic Lane** (or 'lane of opposing traffic'), which is the area *on either side* of the Traffic Separation Zone. The TSZ itself is the area *between* those lanes, ideally kept clear of traffic.
