COLREGs Rules of the Road Practice Test

The responsibility for compliance with COLREGs rules on a vessel lies with the captain and crew collectively. This is due to the collaborative nature of maritime operations, where all members of the crew play a role in ensuring safety and adherence to international regulations. While the captain holds ultimate authority and responsibility for the overall operation and safety of the vessel, the crew is tasked with various duties that directly influence compliance, such as maintaining proper lookout, navigating, and communicating effectively during operations.

All crew members are trained in the COLREGs and work together to prevent collisions and ensure safe navigation. This shared responsibility emphasizes the importance of teamwork and effective communication aboard the vessel. It also highlights that compliance is not solely the duty of one individual or entity; rather, it is a collective effort to ensure maritime safety is upheld at all times.

The other options suggest that responsibility lies with a single entity (the shipowner, the designated officer, or the maritime regulatory authority), but in practice, adherence to COLREGs is a result of a combined effort by all personnel involved in the operation of the vessel.
