During which phase of a BUI is the vessel in motion?

The correct response relates to the initial stage of a Boating Under the Influence (BUI) enforcement process. In Phase 1, the focus is on the actions of the vessel and the behavior of the operator. At this point, the officer is observing visual cues, such as erratic maneuvers or the speed of the vessel, which indicate that the vessel is in motion and potentially being operated under the influence of alcohol or drugs. This phase is crucial as it establishes the basis for further investigation.

Subsequent phases involve more specific assessments and tests that take place when the vessel may be stationary or when an approach to the operator is made. However, in the first phase, the emphasis is specifically on the operational status of the vessel, confirming that it is indeed in motion, which is a critical aspect of initiating a BUI enforcement encounter.
