In a TSS, how should a vessel maneuver around other traffic?

Answer: C — Wait for an opening in oncoming traffic before crossing

In a Traffic Separation Scheme (TSS), the primary concern is to ensure safe navigation amidst the designated traffic lanes while minimizing the risk of collisions, particularly where vessels are crossing paths. Choosing to wait for an opening in oncoming traffic before crossing is the most prudent approach. This strategy allows vessels to assess the distance and speed of approaching vessels, thereby ensuring that they can cross safely without impeding the movement of others. Waiting for a safe opportunity aligns with the COLREGs principles regarding the need for caution and the responsibility of vessels to avoid collisions. By remaining aware of the traffic situation and waiting for suitable gaps, a vessel can effectively navigate through busy areas while prioritizing safety.
