Tall stalks obstructing drivers’ views are a fall hazard in the Corn Belt, but the danger could be greater as farmers seek to cash in on higher prices by expanding their fields closer to the edge of roads.

With corn commanding twice what it did last year, farmers from Pennsylvania to the Dakotas have tried to plant as much as possible. The federal government has estimated this year’s planting at 92.2 million acres, up 5 percent from last year.

In some cases, that means farmers have planted right up to the gravel in remote areas, a practice that can have deadly consequences at unmarked intersections.
