BOTH INTERNATIONAL & INLAND A vessel using a traffic separation scheme shall NOT take which action?

Correct Answer: Option D — proceed in an inappropriate traffic lane

Rule 10(b)(i) requires vessels to proceed in the appropriate traffic lane in the general direction of traffic flow for that lane. Proceeding in an inappropriate lane, such as against the flow of traffic, is a direct violation of the scheme's design and significantly increases the risk of head-on collisions.
