There were fewer fatalities on Iowa roadways this past Memorial Day weekend, but there’s been an over-all increase in road-related deaths in the first six months of this year. An Iowa Department of Public Safety report shows there have been 157 deaths on Iowa’s roads so far this year, and the agency says that’s a “steep increase” over the same period last year. The state’s Public Safety Commissioner is urging motorists to remember to buckle up and drive the speed limit. Three people died in traffic accidents during the Memorial Day holiday. State troopers issued nearly two-thousand speed tickets over that holiday period and made 50 drunken driving arrests on the highways.
