In restricted visibility a power driven vessel?

In restricted visibility, a power-driven vessel must navigate with caution and take specific measures to ensure safety. It is required to sound the appropriate signals, such as prolonged blasts on the whistle, to indicate its presence to other vessels. Additionally, the vessel should reduce speed, maintain a proper lookout, and be prepared to take evasive action if necessary. Implementing these precautions helps prevent collisions and ensures safe navigation in challenging conditions.
