I think you are missing my point. Driving in whiteout conditions and you veer off the road into a 2-3' deep ditch, having chains on is not going to help if the vehicle is buried uo to it's frame and axles. Also the article does not mention how much snowfall there is on the road. Many times, the wind is bad enough that the snow is literally blown off the road and the people crash simply because they are driving too fast for road conditions and they cannot see 2' in front of them and loose sight of the road. There are some current or ex Leo's and some firefighters/1st responders in this forum and others who can attest to this also.

Lets assume they had tire chains on and the same situation occurred and they got stuck. I am almost certain that if they would be foolish enough to walk anyways..regardless of the extenuating circumstances.

Anyway, I think we have beaten this subject enough....time for me to move on to some other subjects and threads.
