Deputies cited Friday mornings fog as the cause of a semitractor-trailer crash along 1100 Street (Old 169) between Iola and Humboldt. The driver, whose name was not released, told deputies his windshield fogged over. He lost control, left the roadway and struck a culvert and row of utility poles. The driver was hauling a load of coke, used in cement production, to Monarch Cement in Humboldt. Coincidentally, the crash occurred on Monarchs property north of town. The driver was not injured.
