A dust storm usually arrives suddenly in the form of an advancing wall of dust
and debris which may be miles long and several thousand feet high. They strike
with little warning, making driving conditions hazardous. Blinding, choking
dust can quickly reduce visibility, causing accidents that may involve chain
collisions, creating massive pileups. Dust storms usually last only a few minutes,
but the actions a motorist takes during the storm may be the most important
of his or her life.
In the past, motorists driving in dust storms have pulled off the roadway, leaving lights on. Vehicles approaching from the rear and using the advance car's lights as a guide have inadvertently left the roadway and in some instances collided with the parked vehicle. Make sure all of your lights are off when you park off the roadway.
During threatening weather listen to commercial radio or television or NOAA Weather Radio for Dust Storm Warnings. A Dust Storm (or Sand Storm) Warning means: Visibility of 1/2 mile or less due to blowing dust or sand, and wind speeds of 30 miles an hour or more.
