Which statement about the Navigation Rules is TRUE?

The statement that all vessels must adhere to the Navigation Rules at all times is indeed correct. The Navigation Rules, also known as the "Rules of the Road," are a set of regulations developed to ensure safe navigation and prevent collisions on the water. These rules apply to all vessels, regardless of their size or type, whether they are large commercial ships, small recreational boats, or anything in between.

The rules provide a framework for how vessels should operate in various situations, including encounters with other vessels, when maneuvering in confined waterways, and while at anchor. This consistency helps maintain order and safety on the water, facilitating safe interactions among different types of marine traffic. Therefore, adherence to the Navigation Rules is mandatory for all vessels at all times, not just under specific circumstances or during certain times of day.
