How is the winter storm affecting transportation across multiple states?

The winter storm is wreaking havoc on roads across the heartland, creating dangerous icy conditions that have led to numerous accidents. In Oklahoma City, vehicles are spinning on icy roads, including a Lowe's truck that lost control. Drivers face additional hazards from frozen debris, with one incident involving ice flying off a tractor-trailer and punching through a driver's windshield. The dangerous conditions have prompted North Carolina to declare a state of emergency due to concerns about power outages and road safety. Officials are working to manage the impacts as freezing rain turns roadways into "ice rinks," resulting in multiple crashes including a snow plow being clipped by a semi that later crashed into a barrier wall.
