An oversize permit is not valid when visibility is reduced to one-half mile or less by weather, dust, or smoke. An oversize or overweight permit is not valid when the road surface is slippery because of snow, ice, slush, or frost. Highway patrol officers may further restrict or prohibit operation under any oversize or overweight permit during periods when, in their judgment, weather conditions make continued operation unsafe.
