In restricted visibility, a power-driven vessel underway must take specific precautions to ensure safety and comply with maritime navigation rules. It is required to sound appropriate sound signals, maintain a proper lookout, and reduce speed to a safe level to avoid collisions. Additionally, the vessel should be equipped with radar and, if possible, use it to detect other vessels in proximity. The vessel must also be prepared to take evasive action if necessary.
In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every 2 minutes. This signal indicates the vessel's presence and helps prevent collisions when visibility is limited. The prolonged blast typically lasts about 4 to 6 seconds.

A power-driven vessel underway in restricted visibility is required to sound a prolonged blast on its whistle every two minutes. This signal typically lasts for about four to six seconds. The purpose of this sound is to alert other vessels of its presence in conditions where visibility is limited, ensuring safety on the water.
In restricted visibility, a power-driven vessel under way is required to sound one prolonged blast every 2 minutes. This signal is used to indicate the vessel's position and to alert other vessels in the vicinity. The prolonged blast lasts for about four to six seconds.
A power-driven vessel underway in restricted visibility is required to sound one prolonged blast at intervals of not more than two minutes. This signal indicates the vessel's presence and helps prevent collisions. Additionally, if the vessel is making way through the water, it may also sound two short blasts to indicate its maneuverability.
