"Being a former mayor, I never really liked it when people up here started telling us how we should run our city," Rielly said.

Sen. Tom Courtney, D-Burlington, said he was surprised to receive a letter from Clive authorities that contained a photo of his Corvette going through an intersection that he believed was a yellow light at the time. But the letter also contained a citation for a red-light violation.

"Now I stop on yellows," he said.

Courtney said he believed the monitoring devices probably are good if it can be proved that they save lives. "I just want to make sure that it's saving lives and not just making money," he said.

Rep. David Tjepkes, R-Gowrie, chairman of the House Transportation Committee, has asked DOT officials for information about how state regulate the use of speed cameras and red-light cameras. He said he wants to make sure the use of monitoring cameras is uniform across the state, that cities can justify when and where they are installed, and that cameras are used as a tool in an overall traffic enforcement strategy.

DOT Director Nancy Richardson said Iowans should not expect to see traffic-monitoring cameras on state or interstate highways any time soon.
