TUCSON, Ariz. -- Authorities say a dust storm moving through southern Arizona is being blamed for a four-vehicle accident on Interstate 10 near Picacho Peak.
Arizona Department of Public Safety officials say two semi-trucks jackknifed and two passenger vehicles were involved in the accident that occurred about 2 p.m. Monday.
Four people were taken to Tucson-area hospitals, but DPS officials say none of the injuries are life-threatening.
DPS says low visibility from a dust storm likely caused the accident.
They say the westbound lane of I-10 at Picacho Road is partially blocked and there's no immediate word on when the wreckage can be cleared.
