The latest article did not change my opinion much if at all. One knows or should know the only thing you can expect is the unexpected.
The issue of the sign saying one lane or two was closed is a red herring in my opinion. Whenever a lane is closed one has to expect traffic congestion. Even if you are in what you think is a through lane there is a high likelihood of merging traffic that will be coming into your lane.
I am not sure what a blind curve means on an interstate. Interstates are built to the absolute highest standards for width, degree of curvature and sight distance. There are exceptions to the standards but generally they are accommodated by speed reductions.
Sitting in the cab of a motor-home should give you a better view of the road ahead. You are above most of the vehicles in front of you and can see farther ahead because of that. It should have become quickly apparent more than 1 lane was closed by observing the traffic congestion, etc ahead in spite of what the sign said.
All of us who have read and/or posted must remember this when we are driving and act accordingly. Numerous lives were affected by that accident for all of the families of the people involved.
