The City of Chicago began installing red light cameras seven years ago.
In recent years, several suburbs have added them.
Supporters say they make intersections safer and encourage safe driving.
Critics says they are really all about generating money."Why are cameras being put up, especially in my district, cameras are being put up at every corner, if it was about safety, it would, put up those cameras up only at intersections that have high incident rate of accident," said State Sen. Dan Duffy, (R) Barrington. Senator Duffy says 12 other states have passed laws similar to the one he's supporting.
