A truck carrying guard rails loses control on slick roads, causing the load to shift.
That's when police say some of the metal pierced the pickup truck's cab, killing the driver.
It all took place Tuesday afternoon on Kentucky 92 in Whitley County near the McCreary County line.
Police spent several hours working the scene and traffic was backed up for a while.
Information is being released on the truck driver, but we're told the road was very slick due to rainy weather.
