What is the maximum speed allowed with a visibility of 30 meters?
1 Answers
With a visibility of 30 meters, the speed should not exceed 20 kilometers per hour. Below is an introduction about visibility: Introduction: Visibility refers to the maximum distance at which a person with normal vision can distinguish an object from its background. Environmental Impact: In exceptionally clear air conditions, such as in the Arctic or mountainous areas, visibility can reach 70 to 100 kilometers. However, visibility is usually reduced due to atmospheric pollution and humidity. During atmospheric pollution events, aerosol pollutants like dust, smoke droplets, fog, falling dust, floating dust, and suspended particles can affect the atmospheric extinction coefficient and visibility to some extent.
