In daytime fog, unless you are literally in traffic....use rear fogs all the time whilst the thick fog is there.

Cars can become invisible very quickly in the daytime with just sidelights. At night they are far more visible simply because it is dark, and yes the need for those fogs is slightly lessened.

But in daylight, almost essential.


But basically..if you can clearly see the car in front for a sensible distance....why the fuck would you think you need your rear fog on when there is someone directly behind you ?
I'd love machine guns on the front of my car to obliterate cunts in front ( and rear ) with their fog lights on when not needed.
