SIOUX CITY, Iowa (AP) — Sioux City has filed a lawsuit seeking to block the state Department of Transportation’s new rules limiting traffic enforcement cameras. The Des Moines Register reports Wednesday that Sioux City filed the lawsuit in Woodbury County District Court, saying the regulations make it impossible for the city to use cameras along Interstate 29. The suit asks a judge to stop the rules or at least put them on hold until the litigation is resolved.

The Transportation Department’s rules took effect Feb. 12, though agency director Paul Trombino says cities don’t have to immediately remove cameras. Under the new rules, local agencies must show cameras are targeting “high-crash or high-risk locations,” and they must justify renewal every year. The lawsuit argues the rules are too broad.
