A state delegate from Baltimore County says public confidence in speed cameras has deteriorated to the point that a state audit and possible reboot are needed.

Del. Jon Cardin said Monday he plans to sponsor a bill calling for an audit of state and local speed camera tickets with an eye on rooting out bogus citations.

"Maybe it's time to go back to the drawing board," Cardin said.

The Baltimore County Democrat said he is in the process of drawing up a bill that would create an audit due to legislators by October 2013. Instances of bogus tickets issued to drivers would result in a $1,000 per incident penalty, though it is not clear if the jurisdiction or the speed camera vendor would be responsible for the fine, Cardin said.

"I'm not trying to put people out of business," Cardin said. "I'm concerned with try to create a system that is accurate and keeps people safe."
