DES MOINES, Iowa (AP) — Six Iowa cities have submitted reports outlining traffic camera use to state transportation officials and now await word on whether they’ll be able to keep their speed and red light cameras on state-run highways and interstates.

The Iowa Department of Transportation implemented rules in February dictating where and why cameras can be installed along state roads and requiring local jurisdictions to submit reports by May 1 justifying camera placement. Steve Gent, director of the Iowa Department of Transportation’s office of traffic and safety, says the department plans to review the reports in coming weeks.

The cities are Cedar Rapids, Council Bluffs, Davenport, Des Moines, Muscatine and Sioux City.

Gent says the review process will involve collaboration between DOT and local officials to fully understand why cities believe cameras are needed.
