Blinding, blowing dust storms, frequent in Arizona during the summer, cause reduced visibility to near zero, creating unexpected and unsafe conditions for motorists. How you react in a dust storm can save your life and the life of others, prevent injuries, and reduce property damage.

Also called a "HABOOB," dust storms are most common between May and September in Maricopa and Pima County.

Although brief, dust storms must be taken seriously because they cause blinding conditions on the highways. Each year, an average of five people lose their lives and many more are seriously injured as a result of sudden, violent dust storms.
