What does Rule 34 emphasize about proceeding through a "TSS" (Traffic Separation Scheme)?

Rule 34 of the COLREGs deals with the conduct of vessels in Traffic Separation Schemes (TSS). The rule emphasizes that vessels should avoid impeding the safe passage of vessels that can only navigate safely within the TSS. This is particularly crucial in maintaining safety and efficiency of maritime traffic, as certain vessels, like large tankers or vessels that require deep drafts, may have limited maneuverability and reliance on the TSS for navigating safely.

When vessels adhere to this rule, they help ensure that those with specific navigation needs can operate without disruption. This is vital in busy shipping lanes where traffic can be dense and where even minor delays or obstructions could lead to dangerous situations.

While maintaining speed, frequent communication, and lane changes are aspects of navigation and operational practices, they are not the primary focus of Rule 34. The essence of the rule lies in safeguarding the passage of vessels that depend on the dedicated routes established by the TSS, thereby upholding safe and orderly maritime traffic.
