In restricted visibility, a power-driven vessel must navigate with caution and take specific precautions to avoid collisions. It is required to use radar, sound signals, and appropriate navigation lights to maintain awareness of other vessels. The International Regulations for Preventing Collisions at Sea (COLREGs) dictate that such vessels should reduce speed, and when necessary, take all way off to ensure safe navigation. Additionally, they should be prepared to take evasive action if required.
On power-driven vessels, navigation lights must be on during periods of restricted visibility.

one prolonged blast
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.
The should comply with IRPCS and be on between sunset and sunrise and in restricted visibility
one prolonged blast
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.
