To whom do the collision avoidance rules apply?

The correct answer is that the collision avoidance rules apply to all vessels at sea. The International Regulations for Preventing Collisions at Sea, commonly known as COLREGs, are designed to provide a set of guidelines that enhance safety by preventing maritime collisions. These rules are applicable to all types of vessels, regardless of their size, purpose, or whether they are commercial, pleasure craft, or naval vessels. By establishing a standard for safe navigation, the COLREGs ensure that all vessels follow the same fundamental principles when encountering one another on the water. This universality is crucial because it allows for predictable actions that contribute to maritime safety and order at sea.

The focus on all vessels reinforces the importance of safety and navigation practices across diverse types of maritime activities. This includes not only large commercial vessels but also small boats, yachts, and military ships, thereby creating a comprehensive framework for cooperation and safety in shared marine environments.
