It's not just dust storms you have to watch out for. When I was just starting my freshman year of college, a sudden fog bank rolled in over I-40 between Little Rock and Conway. Apparently it all started when a compact car slammed on their brakes, not thinking about the dozen or so tractor trailer rigs behind them.
By the time we got through, they had cleared most of the debris and started burying a couple dozen head of cattle in the median. We found out later that they found a minivan in the wreckage. It took a while, because it had been between two of the rigs (both of which burned to the ground). The occupants were identified through the VIN on their vehicle and dental records because there wasn't enough left of them to scrape into a Sucrets box (almost literally)
