Tractor trailer in pile-up in wind storm

A female passenger of a pick-up truck is dead after a pile-up in Nevada which led to her vehicle being rear-ended by a truck driver from Chicago.  News reports indicate that at the time of the wrongful death truck accident, high winds caused blowing sand and dust which reduced visibility to near zero in the area of the truck accident.

49 CFR Part 392.14 requires truck drivers to slow their vehicles and to exercise extreme caution when hazardous conditions such as snow, ice, fog, or smoke are present and if conditions are sufficiently dangerous, to cease operations and pull to the side of the road or exit the road.  Wind-induced dust storms are not explicitly mentioned, but clearly they caused hazardous conditions at the time of the accident which should have resulted in this truck driver getting off the highway instead of continuing on in conditions when he could not see the vehicles ahead of him well enough to stop before killing someone.
