To provide added safety, or to raise money for a municipality? There is a gross miscarriage of justice by certain local governments on these red-light violation laws as they relate to right turns on red. These traffic lights are there to regulate traffic at busy intersections. Illinois and most, if not all, states allow drivers to turn right on red after a full stop and ensuring there is no oncoming traffic; this can be done in a second or two. I understand local rules say that a driver must stop for three or four seconds regardless of whether there is any oncoming traffic.
Let's face it, this is purely a money-raising scheme and an unlawful fee on innocent drivers. It has nothing to do with safety. Many states do not allow this practice.
