The best example of restricted visibility is dense fog, where the thick moisture in the air significantly reduces the distance one can see, often to just a few feet. This condition can severely impact driving, navigation, and outdoor activities, as landmarks and road signs become obscured. Other examples include heavy rain, snowstorms, or smoke from wildfires, all of which can create similar challenges in visibility.
rely upon the aircraft instrument indications.

In open waters, visibility is generally considered restricted when it is less than 1 nautical mile (1.85 kilometers). This reduced visibility can be due to various factors such as fog, rain, or heavy seas. Navigational warnings and precautions are advised in such conditions to ensure safety at sea.
Restricted visibility refers to conditions where the ability to see and navigate is significantly impaired, often due to weather phenomena such as fog, heavy rain, snow, or smoke. In maritime and aviation contexts, this can affect safety and operations, requiring specific protocols and navigational aids to ensure safe travel. It is crucial for operators to be aware of visibility levels to mitigate risks associated with low visibility conditions.

Something blocks your line of sight. On a road it could be hills, curves, etc.
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.
