Oklahoma highway drivers warned of roadside grain dumping

Why grain would get dumped on the side of the road is a mystery to many, but it happens. Oklahomans driving north on I-35 may pass a sign warning drivers to not dump their grain trailers before the Stillwater exit on the interstate. These signs are sometimes put up to serve as a reminder for haulers to clean up grain left on the ground. Grain can fall out of trucks and perhaps can be intentionally dumped to reduce load weight or cleaning out trailers.
