Safe speed is the speed at which you can take proper and effective action to avoid collision under the current visibility and traffic conditions. It isn’t a fixed number; you adjust your speed so that you have enough time and distance to observe, assess risks, and maneuver or stop if another vessel presents a collision threat. This means slowing down in fog, rain, or heavy traffic, or when another vessel’s actions create uncertainty, and maintaining a speed that lets you respond promptly while still keeping safe distances.

This concept emphasizes that your ability to act to prevent a collision depends on conditions like visibility and traffic, plus your vessel’s handling and stopping power. It’s not about waiting a certain amount of time before acting, and it doesn’t replace prudent watchkeeping—you still need to keep a proper lookout and monitor others as you adjust speed.
