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.
If dense dust is observed blowing across or approaching a roadway, pull your vehicle off the pavement as far as possible, stop, turn off lights, set the emergency brake, take your foot off of the brake pedal to be sure the tail lights are not illuminated.
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.
