Which of the following statements is true regarding collision responsibility?

The statement that no vessel can be exonerated for collision is true. According to the COLREGs, all vessels have a responsibility to navigate safely and take measures to avoid collisions. This principle means that if two vessels collide, both parties may bear some degree of responsibility, regardless of the circumstances, including the size of the vessels or whether one was following the rules properly. It emphasizes that all mariners must take precautions to avoid accidents and adhere to the rules set forth in the regulations.

In the context of the other statements, the idea of a "right of way" can be misleading since COLREGs are more about establishing responsibilities and actions to take when vessels encounter each other rather than a definitive right of way. The concept that collisions favor larger vessels is inaccurate as it is not the size but the actions of the vessels involved and their compliance with navigation rules that determine responsibility. Lastly, collision responsibility does not depend on whether a vessel is equipped with radar; all vessels, regardless of their equipment, must comply with navigational rules and maintain a proper lookout to prevent collisions.
