A vessel using a traffic separation scheme is forbidden from doing?

• A. Proceeding in an inappropriate traffic lane
• B. Proceeding in the correct traffic lane
• C. Entering the traffic separation scheme
• D. Stopping within the separation zone

Answer: (A)

In a traffic separation scheme, the lanes are designated for traffic moving in specific directions, and vessels must follow the lane that matches their course. Proceeding in a lane that isn’t designated for your direction disrupts the orderly flow of crossing and opposing traffic and creates a real risk of collision with vessels in the proper lanes. That is why this action is forbidden. Entering the traffic separation scheme and proceeding in the correct lane align with how the scheme is intended to be used, and stopping within the separation zone is not the explicit prohibition described in this context, though it is generally avoided because it can block traffic.
