The Iowa Department of Transportation has posted a photo of a semi, whose driver found out the hard way yesterday (Sunday) morning, that barricades and “ROAD CLOSED” signs aren’t just suggestions to stay away from certain areas. (See the photo below) The driver ignored the signs and barricades posted on Highway 2 at the Missouri River, where the road was completely torn-up. Their rig ended-up being tilted, with the tractor section partially off the road and the trailer jackknifed onto the shoulder. Officials ask motorists to “Please pay attention and don’t go around traffic control devices. They are in place to keep you safe.”
