A vessel must proceed at a safe speed __________.

A vessel must proceed at a safe speed __________.

• A. at all times
• B. only in daylight
• C. when visibility allows
• D. only when not near other ships

Answer: (A)

Safe speed means the speed at which, given all the conditions, a vessel can take proper and effective action to avoid collision. The best answer reflects that this requirement applies at all times, not only in certain circumstances. You’re expected to maintain a speed that allows you to see and react to other vessels, and to stop or maneuver in time if needed. The rule isn’t limited to daylight, good visibility, or being away from other ships; those factors may influence how you adjust your speed, but the baseline obligation is to proceed at a safe speed under all conditions. In practice, factors like visibility, traffic density, weather and sea state, depth, maneuverability, stopping distance, and navigational hazards all inform what constitutes a safe speed in a given situation.
