I’ve only experienced whiteout conditions once in my life while driving, it is similar. I was on whatever interstate goes north from Minneapolis to St. Cloud, wind kicked up and boom, couldn’t see a blessed thing other than the tail lights of the car directly in front of me. Followed them off the edge of the pavement and nearly got the rental stuck.
There’s a spot south of Flagstaff (AZ) where this periodically happens... You’re on an 8,000+ foot mountain with just a little guard rail to keep you from going over the edge. The fog came up on us so fast that we could barely get over to the edge of the road. Luckily, someone was pulled off ahead of us too and we just had enough shoulder. It was the scariest thing ever. We kept our seatbelts on and just prayed we didn’t get hit (well, not like the seatbelts would have helped much going over that much mountain, but still).
