Louisiana Boater Safety Practice Exam

A "risk of collision" occurs when two vessels are on a path that could potentially lead to them colliding. The scenario in which an approaching vessel continues on a collision course signifies that the two vessels are not taking any action to alter their respective paths to avoid coming into contact. This situation indicates a direct threat, as it suggests that without intervention, the vessels will eventually intersect in a way that could result in a collision.

In contrast, other situations, such as a vessel turning to avoid contact or moving away from another vessel, imply that actions are being taken to prevent a collision. Maintaining a safe distance between vessels indicates that there is no immediate threat or likelihood of collision, which also contradicts the definition of a "risk of collision." Therefore, recognizing the implications of vessels maintaining their courses helps identify when immediate action is necessary to ensure safety on the water.
