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.

In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every 2 minutes. This signal is meant to indicate the vessel's presence to other nearby vessels in low visibility conditions. The prolonged blast lasts for about 4 to 6 seconds. This sound signal helps enhance safety by alerting others to the vessel's location, allowing for better navigation and collision avoidance.
