Same reason sunsets are red. The red, orange, pink yellow end of the light spectrum is the longer wavelength light. Longer wavelength light penetrates dust and fog and rain spray better so that it can go out, illuminate the road and travel back with useful information for your eyes as compared to white light which bounces off the fog and causes glare and makes your vision worse. Same effect with sunsets - when the sun is perpendicular at noon, it is shining directly through a thin cross section of atmosphere, so all the colors come through pretty well and it looks white/full spectrum. But in the late afternoon, the sun is really low and close to parallel with the ground, so it is shining through a long cross section of atmosphere, full of dust, water vapor, and other atmospheric gases. The longer wavelength lights pass through better so sunsets look red, orange, pink, yellow. Same sun, different filter. That's why fogs are yellow/amber/orange.
Plus they smell like cheese

Related issue is why fighter jets and BMWs have red cockpit lights. It is not that they hurt your eyes less in the dark it is that for whatever reason (likely our sensitivity to long wavelength light), things illuminated with red light are more legible for a given amount of light than things illuminated with other colors. So with red dash lights you can run them lower and get the same legibility as a brighter green or white dash light.
There you go - more than you ever wanted to know about long wavelength light.
