A gust of wind sweeps over bare soil, kicking up enough dirt and dust to cut visibility to nearly zero, and for drivers, the dust storm seems to come out of nowhere.Such conditions resulted in a pileup on Interstate 70 last week in western Kansas involving dozens of cars and trucks that left eight people dead.

This was the scene of devastation after dozens of vehicles collided in the US state of Kansas. At least eight people were killed in the major crash caused by a dust storm on Friday. Aerial images show the scale of the devastation, with scores of lorries and cars crumpled together.
