Des Moines Register: A 60-day moratorium on new digital billboards was unanimously approved on Monday by the Des Moines City Council. The temporary measure prohibits the construction of new digital billboards and the conversion of existing billboards to enable the technology. City Councilman Tom Vlassis, who proposed the moratorium, is concerned that intermittent image changes on digital billboards could pose traffic hazards.
