Gov. Terry Branstad and the state's transportation director say automated cameras designed to catch motorists running red lights or speeding should be used only after other engineering and enforcement solutions have been tried.
The Gazette in Cedar Rapids reports that Branstad says he's concerned every village in the state may want cameras.
Iowa cities using cameras include Cedar Rapids, Sioux City, Davenport, and Des Moines. Some generate millions of dollars a year in fines.
DOT Director Paul Trombino says the agency has new guidelines for using cameras on Iowa's primary highways. The guidelines say cameras should seldom be used as a long-term solution for speeding or red-light running.
Banning cameras or establishing uniform rules for operation has come before lawmakers before and is likely to surface again this year.
