In a Traffic Separation Scheme, vessels should:

• A. Follow the designated lanes and signals to minimize risk.
• B. Ignore lane markings when traffic is light.
• C. Cross the lanes as needed to pass ahead.
• D. Enter at any point as long as traffic is light.

Answer: (A)

Traffic Separation Schemes are laid out to keep opposing traffic apart and reduce collision risk by organizing vessels into directional lanes. When you follow the designated lanes and any accompanying signals, you move in the same predictable path as other ships traveling in the same direction, which minimizes crossing or head-on conflicts. This disciplined lane-following is the core reason the scheme exists: to manage traffic flow and keep maneuvering decisions simple and safe in busy waters.

Ignoring lane markings, crossing lanes unnecessarily, or entering the area at any point breaks the organized flow and creates unpredictable trajectories, increasing the chances of collision.
