Question 22 GLI05 - Master or Mate of LT 200 GRT

The Correct Answer is A **Explanation for Option A (Correct):** A Traffic Separation Zone (TSZ) is a fundamental component of a Traffic Separation Scheme (TSS). Its primary purpose, as defined by the International Regulations for Preventing Collisions at Sea (COLREGs), is precisely to physically and visually separate opposing lanes of traffic within the scheme. Rule 10 (Traffic Separation Schemes) states that a TSS is intended to organize traffic, and the TSZ is the specific area designated to separate the streams of traffic proceeding in opposite directions, thereby reducing the risk of head-on collisions. **Explanation for Incorrect Options:** * **B) is located between the scheme and the nearest land:** This description refers to a **Coastal Traffic Zone** (or in some contexts, an Inshore Traffic Zone, although the latter is a separate voluntary route). The Traffic Separation Zone itself is the dividing line *within* the scheme, not the area between the scheme and the land. * **C) is designated as an anchorage area:** Anchorage areas are separate designated zones where vessels are permitted to anchor. A Traffic Separation Zone must generally be avoided by all vessels unless crossing or joining/leaving the scheme, and anchoring within it is strictly prohibited except in emergencies. * **D) contains all the traffic moving in the same direction:** The lane where traffic moves in the same direction is called a **Traffic Lane** (or 'traffic separation lane'), not the Traffic Separation Zone. The TSZ is the barrier *between* the lanes.
