Where is / was the worst fog you've ever been in?

Table Mountain, Capetown. Some mates and i decided to hike up the side which is bloody steep and when the fog rolls in (called laying the table cloth by the locals) its as thick as i have ever seen it- ok, more cloud than fog but still the same.

I once left for a Cape trip on the bike from here, (Eidsvold) at around 5:00am and rolled into Rocky, 300 kms away at 12:00pm, couldnt see more than 100m in front for the entire trip, fog only just started to lift at Midday.

A number of occasions in the vicinity of Armidale-Guyra-Glen Innes. Only had to stop and sleep it out once because of it though. It is more likely cloud than fog in that area as you 4000 ft. up in the air.

Coming down the range from Toowoomba towards Brissy, (dad used to live up there) the fog was so bad that we were out the window looking for the lines, We got about half way down and the brakes actually caught alight. Stressful situation... Funny looking back at it. manged to save the car though, just a little bit of damage to the wheel.

have a good one guys.

Between Jenolan and Edith about two feet ifront of me at night. Headlights off, fogs on best we got on the journey was 25kph.:o

In the clouds up there.

Once in the uk (The date was 17/12/ 1991 to be exact) the fog was so bad i could not see the turn off on the side of the road. I was driving by the white line the middle of the road and all i could see of that was about 5 foot infront of the car. We had real problems finding the turn as we could not see where we were on the road as in we could not see any houses to tell us where we were. Was pretty scary stuff and drove 30 miles in that stuff

The worst place in Australia for fog is, as Numpty’s Missus and Chenz posted, on the escarpment above the Illawarra, on the NSW South Coast and it’s so bad there on such a regular basis that it is one of the few places in Australia where it is legal to drive with your hazard lights on.

The RTA put up huge signs requesting drivers switch their hazard lights on during fog.

The strange thing is that the fog is at it’s worst on summer afternoons and evening because it is usually caused by heavily humidified air coming of the Pacific ocean meeting cooler air coming off the top of the escarpment.

BTW, it’s a great place to find out just how useless ALL forms of fog lights really are.

We had a beauty some years ago traveling on a wet, foggy night on the Clyde Mtn between Braidwood and Batemans Bay. The fog was thick as.... and as we made our way down the hill some odd looking lights glowed in the fog ahead. We stopped very quickly from our slow progress to find a flat bed truck from the NRM* (NSW) doing a 3 point turn halfway down the Clyde on tight winding road so that it could pick up a broken down car, and presumably return to Braidwood. The 3 point turn saved them a trip to the bottom of the mountain to turn around but nearly gave us a Number 1 across the top of our heads.

1 turning onto the highway from sunny corner near bathurst.had to turn vehicle off and get out to hear if anything was coming along highway
2 the top of bulli pass with my father in an fj we turned into a garage for fuel and so did the following 20 or so cars

In OZ, the worst was driving up to Springbrook (gold coast hinterland). Was so thick I had to putter up in first for fear of driving off the mountain.

Worst OS - pea souper while snownoarding in st moritz, so thick I almost skiid into the halfpipe without realising, about 3' visibility!!!
