Police say there's been an alarming rise in urine-filled plastic containers found along a three-mile stretch of Interstate 84 in eastern Oregon.

A litter crew for the Oregon Department of Transportation picked up an estimated 200-300 urine filled plastic bottles, along the highway, about half of which were found in a short stretch dubbed "Three Mile Hill."

Police say that drivers — particularly commercial trucks — are typically driving very slowly through the area.

Police think the price of fuel may be causing drivers to travel slower than normal to save fuel while at the same time passing rest areas or truck stops.

Under Oregon law, improperly disposing of human waste is a misdemeanor which can carry a fine of up to $250.
