Iowa’s one of 12 states that’ll test a special deer warning system. Department of Transportation spokesman Steve Gent says they’re going to install the system this spring along a one-mile stretch of highway 20 near Earlville in Delaware County.Special detectors will set off a flashing light along the roadway when deer are detected, warning drivers to be alert. Gent says the warning system is not cheap.It costs 56-thousand dollars to equip a site with the detection system. Gent and others track the number of deer hit via accident reports. D-O-T crews pick up dead deer hit along roadways and keep a count of those deer. Gent says car/deer accidents have increased dramatically the last several years and they hope this system will prevent some of those accidents.
