This happened on I-29. This was a construction zone, where both directions of traffic were driving on the same side of the interstate. Wife and I were headed the opposite direction of the 4 killed. There was nothing they could do on those bikes. Traffic was very heavy in both directions and the truck just crossed the line. We were about 3/4 to 1 mile behind the truck.
The truck driver needs to be in prison for the rest of his life.
I do not see how any one can put any blame on the four bikers, even if they were driving in very tight formation.
