In response to the evolving COVID-19 pandemic, the City of Chicago has joined the State of Illinois in issuing a Stay at Home order effective Saturday, March 21st at 5pm CT. In addition, City of Chicago facilities are closed to the public. Staff are prioritizing essential services to protect the health and safety of our residents and employees. As such, we may be delayed in responding to non-essential inquiries and service requests. To stay up to date on the City of Chicago’s COVID-19 response, please click here.
Red Light Camera Enforcement is designed to increase safety on Chicago streets by reducing the most dangerous types of crashes at intersections. The different types of crashes between vehicles are rear end, side swipe, angle, and head on. While all crashes are potentially hazardous, Red Light cameras are designed to reduce angle (or “t-bone”) crashes because of their extreme danger to those involved. As individuals comply with traffic signals, serious crashes and injuries reduce significantly.
Chicago began its red light camera program 2003 with enforcement at two intersections: Peterson and Western and 55th and Western. In subsequent years, additional intersections have been added based on crash frequency/severity.
At most Red Light Camera intersections, two approaches are monitored. However, CDOT posts signs at all four approaches identifying the intersection as photo-enforced.

Red Light Community Meetings
Under an ordinance proposed by the Mayor that the City Council approved in May 2015, the Department of Transportation is required to hold a public community meeting before any red-light camera system is installed, removed, or relocated. The Department has been scheduling meetings in local communities to discuss the removal and relocation of Red Light Cameras in 2017. See a list of scheduled meetings.
Reducing the Most Dangerous Types of Crashes
CDOT is committed to improving safety on our streets, and the Red Light Camera Enforcement program is a critical part of this effort. The program has proven effective in discouraging motorists
from running red lights and in reducing the most dangerous types of crashes.
The locations of red light cameras are determined through analysis of the crashes experienced at an intersection. Potential intersections are ranked based on the number of total crashes,
the number of angle crashes, and the angle crash rate. The angle crash rate is the primary criterium used to identify locations for red-light camera installations and relocations.
Angle crashes are most likely to result in serious (incapacitating) injuries or fatalities. The likelihood of serious injury or fatality in a right angle (“T-bone") crash is increased
when the red-light running vehicle is also speeding.
Analyses of Chicago’s red light camera-equipped intersections found that dangerous angle crashes were reduced by approximately 64% at intersections equipped with red-light cameras.
The safety goal of the program remains focused on reducing the most dangerous types of crashes. Rear-end crashes tend to decrease in frequency as driver behavior
changes over time to comply with the red-light traffic laws.
The most recent crash statistics show that between 2005 and 2018 crashes of all types were down at intersections with red light cameras, and overall safety had improved*:
· Dangerous right angle (“T-bone”) crashes decreased by 64%
· All crashes at those intersections were down 59%
· Crashes resulting in injuries were down 40%
· Pedestrian crashes were down 33%
· Rear-end crashes were down by 62%
*Based on comparison from the Illinois Department of Transportation (IDOT) of crashes occurring within 250 feet of the current red light camera-enforced intersections in 2005 and 2018. In 2009, IDOT changed its reporting methodology for certain crash types to include only crashes resulting in $1,500 or more in property damage (increased from $500); this may have an effect on the comparison of total, right-angle and rear-end crashes reported, but does not affect the comparison of crashes involving pedestrians or resulting in injury.
The State of Illinois Vehicle Code (625 ILCS 5/11-208.6) requires municipalities operating automated traffic law enforcement systems to assess the safety impact of each system using the best available data. The analysis shall cover a period of time before and after installation of the system sufficient to provide a statistically valid comparison of the safety impacts. The analysis shall be made available to the public and posted on the website of the municipality.
Frequently Asked Questions
How do red-light cameras work?
The digital cameras are tied into the traffic signal system and use radar to detect vehicles approaching the intersection. When the cameras record vehicles entering the intersection after the light turns red, they take still and video pictures of the rear of a vehicle, including the license plate.
Who reviews those images?
The images receive an initial review by the camera vendor to make sure the image quality is sufficient. The images are then forwarded to the City's Department of Revenue for review and processing. Citations are sent to the registered owner of the vehicle shown in the pictures. Any motorist who receives a red-light camera ticket can review a video of their red-light violation on the city’s web site: www.cityofchicago.org/finance
How long is red-light camera video available for review?
24-hour streaming video from red-light cameras is available for review for 30 days. Video of red-light violations are available for review for a period of two years.
What about drivers turning right on red, or still traveling through the intersection when the light turns red?
Red Light Cameras do not take pictures of vehicles legally turning right on red after a complete stop—as required by law—or caught in the intersection after the light turns red (for example, a car already in the intersection waiting to make a left turn).
How are red-light camera intersections chosen?
The City reviews crash data, paying particular attention to the number of "right-angle crashes" at these intersections--indicative of accidents caused when one vehicle runs a red light and strikes another. Only locations with a high number of right-angle crashes are chosen for red-light cameras.
How long are Chicago’s yellow lights?
Chicago's yellow lights are set at 3 seconds on streets where the approach speed limit is 30 mph or lower, 4 seconds on streets where the approach speed limit is 35 mph or higher. These timings fall within the guidelines of the Federal Highway Administration’s Manual on Uniform Traffic Control Devices, and adheres to recommendations by the Institute of Transportation Engineers.
Chicago’s yellow times are more than adequate for a driver traveling the speed limit to react and stop safely. The three-second timing has been in place for several decades. No signal timings were changed before or after the implementation of red-light cameras.
Why not just make yellow light longer?
Changing signal timings will not solve the problem of drivers running red lights.
The purpose of the yellow light is to warn drivers that the light is turning red. It is not intended to promote speeding or risk-taking. Unfortunately, too many drivers believe that yellow is a sign to speed up -- when in reality it should be a sign to slow down.
Extending the yellows won't solve the problem because motorists will learn that they now have an additional second or two, and will still treat the yellow as an extension of the green. The behavior that some drivers exhibit—running red lights—will not change. Longer yellow lights will not be beneficial to the overall safety of the intersection.
Additionally, a timing change would have a negative impact on traffic flow throughout the city, increasing congestion and reducing travel times.
So-called “rolling stop” right turns on red aren’t that dangerous—why issue tickets for them?
A red-light violation is a red-light violation—whether you’re going straight or turning left or right. State law is clear: A right turn on red is only allowed after a vehicle comes to a complete stop. A vehicle “rolling” though the turn jeopardizes pedestrians and bicyclists who may be crossing the street on the walk sign.
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.
Are there signs posted where automated red light cameras are enforcing?
Yes, signs are posted at all legs of the intersection where automated red light cameras are enforcing in the City of Chicago. The City currently exceeds automated enforcement signage requirements from the Illinois vehicle code (IVC) (625 ILCS 5/11-208.6. (k) An intersection equipped with an automated traffic law enforcement system must be posted with a sign visible to approaching traffic indicating that the intersection is being monitored by an automated traffic law enforcement system), and the manual on uniform traffic control devices (MUTCD), where automated red light cameras are operating.
Automated red light camera signage is checked regularly by the City’s vendor to ensure the required signage is present at automated red light camera intersections.
