What should vessels on a collision course do to ensure safety?

Vessels on a collision course must evaluate the possibility of collision and act accordingly to ensure safety. This means that both parties involved should assess their relative positions, speeds, and the risk of a collision based on the International Regulations for Preventing Collisions at Sea (COLREGs). By doing so, they can make informed decisions on how to maneuver—whether that involves altering course, reducing speed, or taking other actions to avoid a collision.

This approach emphasizes the importance of situational awareness and proactive decision-making in maritime navigation. By evaluating the risk of collision, vessels can coordinate their movements in a manner that significantly reduces the likelihood of an accident, prioritizing safety for all involved.

The other choices lack the necessary precautions for safe navigation. Ignoring potential collisions or simply not adjusting course while communicating will not address the immediate safety concerns. Likewise, taking separate routes without considering each other disregards the fundamental principles of navigation safety and could lead to dangerous situations on the water.
