where you can see fog and it's below 4 degrees......

A compelling argument pipey.

idiots will always be idiots

it is a proper peasouper here in Suffolk but idiots till driving around with no headlights on

sadly these cants usually end up killing or injuring other people instead of themselves

Not really the topic but i never knew they existed and bet most other people don't either, fogbows.
Mrs was out for a walk and someone pointed it out to her.

Tbf usually warnings are on motorways with a reduced speed limit,fog or not idiots are everywhere on the road,mostly in a hurry.

I don't think I'd drive at any speed in those conditions. BigH, I lived in The Fens for many years and I've never seen such thick fog in my life. On more than 2 occasions I just had to try and find somewhere safe to park up and just slept in the car til the morning.

1 March 2008 : Around 6.39 am UAE time a series of vehicle crashes occurred, involving cars, SUVs, buses and trucks, because of heavy fog on the Abu Dhabi-Dubai highway near Ghantoot, Abu Dhabi, in the United Arab Emirates, leading to the worst ever crash and multi-vehicle pileup in the country’s history. According to Dubai-based Gulf News and Reuters, the incident killed 3 people and injured 277, involving 60 vehicles from which 25 caught fire according to Abu Dhabi Police.

I changed our driving policy based on that incident.
