Question 22

The Correct Answer is A. A Traffic Separation Zone (TSZ) is a fundamental component of a Traffic Separation Scheme (TSS). According to both international regulations (COLREGs, Rule 10) and inland navigation rules that adopt this concept, the primary function of the separation zone is to **separate the lanes of traffic moving in opposing directions**. This is crucial for safety, as it minimizes the risk of head-on collisions between vessels using the scheme. **Why the other options are incorrect:** * **B) is located between the scheme and the nearest land:** This description defines a **Coastal Traffic Zone (CTZ)**, not the separation zone. The CTZ lies between the inner boundary of the TSS and the coast. * **C) is designated as an anchorage area:** Anchorage areas are separate designated zones where vessels may anchor. The separation zone is specifically intended to be kept clear of traffic and obstructions (including anchoring) to maintain safe separation. * **D) contains all the traffic moving in the same direction:** The area that contains traffic moving in the same direction is called a **Traffic Lane**, not the Traffic Separation Zone.
