State Transportation Cabinet spokesman Chuck Wolfe says snow plows are out in all 120 counties. He says the main priorities are the interstate highways, parkways and other major routes.
More than a foot of snow has fallen in many parts of Kentucky. In some areas, the snow is so thick that some snow plows have gotten stuck or blocked by stranded vehicles.
Wolfe said Thursday that the snow fell so fast that roads had fresh blankets of snow on them soon after being plowed.
Some roads were blocked by tractor-trailers that jackknifed due to the slick conditions.
