Chicago red light FAQ page
Why does the violation go to the car’s registered owner?
As the registered owner of the vehicle, one has a legal responsibility for all parking fines and non-moving violations assigned to your vehicle. This new system is similar to Chicago's parking ticket system. If you loan your car to a friend, a relative or a child, you assume that person will obey the law while driving.
Are red light camera violations considered a moving violation?
No. They are administrative violations, similar to a parking ticket.
