Out for a walk with the dog this morning I was reminded of how almost no-one seems to understand that FOG lights are to be used in the FOG! Out of dozens of cars that passed us I saw only 1 using fog lights, despite thick heavy fog all around. Most had no lights on at all, some had their parking lights on, some had headlights on full beam, most had opted for half beam - ( I know, it's better than nothing at all).
Yet, at night I see plenty of people driving round with full beam and fog lights on.
Isn't it just common sense to realise when and what lights to use in certain conditions
