Duty to warn oncoming drivers - traffic

Interesting accident in the Iowa State Patrol (ISP) crash reports this week. Unfortunately it resulted in the death of a 39-year-old man from Fremont, Iowa. The one question I have is why wasn't there a spotter in the road or some warning device (cones) to warn or stop oncoming traffic. Would the driver of the 1986 Toyota still be alive today had there been some way to warn him of the feed trailer blocking County Road G77?
