Because the scattering of this light is less in air molecules.

Scientific explanation why red color is a symbol of danger is "Red color has maximum wavelength in the spectrum. Scattering of a color (by air particles) is inversely proportional to the forth power of wavelength of that color, Thus red color scatters least of all colors. Since red color scatters least...

Scientific explanation why red color is a symbol of danger is "Red color has maximum wavelength in the spectrum. Scattering of a color (by air particles) is inversely proportional to the forth power of wavelength of that color, Thus red color scatters least of all colors. Since red color scatters least so it will travel more distance than all other colors. Red color will travel in the form of a dense beam of light rather than traveling as number of less dense scattered beams. So it will visible to us more effectively even in the rain or fog. General explanation is since blood and highly burnt matters are red in color. So it indicates danger. read less

The wavelength of red colour is maximum in the spectrum. From larger distances also you will be able to identify red colour. that's why traffic signals and danger signs in red colour.

Red light is having highest wavelength among other color and is scattered the least by air molecules. According to Rayleigh's law of scattering, "the amount of scattering of a light of wavelength ? is inversely proportional to the fourth power of its wavelength.".

Because it is scattered very less nd it has the highest wavelength

Due to its wave length. Red color have maximum wavelength i.e about 620-750mm, which can be easily identified from far place. So danger signal is always in red color.
