Low visibility refers to conditions where the distance one can see is significantly reduced, often due to weather phenomena such as fog, heavy rain, or snow. This can pose challenges for drivers, pilots, and pedestrians, as it increases the risk of accidents and makes navigation difficult. In many regions, low visibility is measured in terms of miles or meters. For example, when visibility drops below 1 mile, it is considered low, and safety precautions are typically advised. Various tools, such as fog lights and reflective gear, can help improve safety in these conditions.
