Reply #183: I've never had a fog bank surround me unexpectedly [View All]

When I see one up ahead, I slow down before entering it. Don't you?

You said the driver outran his headlights. True. How far do headlights penetrate a thick cloud of smoke? A few feet?

If you can see ahead only a few feet, you should reduce speed to maybe 1-2 MPH. I've had to do that in pea soup fog many, many times. I've been in desert sandstorms where visibility dropped to literally zero in a very short time, but not without warning. When that kind of thing happens, you should already be stopped when visibility hits zero.

And somehow I've always managed not to run into other cars that were stopped or going slow ahead of me in the fog.
