Chicago Bike Accidents Surged 46% Between 2022 and 2025
Chicago Bike Accidents Surge 46% Since 2022
8,389 cyclists have been struck on Chicago roads from 2022 through 2025, and nearly 1 in 3 of those accidents involved a driver who fled the scene.
Research by Briskman Briskman & Greenberg
Every year since 2022, Chicago has set a new record for bike accidents. What began as a troubling data point has become an undeniable pattern: more cyclists are being struck, more are being injured, and a growing share of the drivers responsible are choosing to flee.
Briskman Briskman & Greenberg's Chicago bike accident lawyers have seen firsthand an increase in bike accident injuries, so we conducted an independent study of every bike accident recorded by the City of Chicago.
A comprehensive analysis of Chicago crash records covering 2022 through 2025 reveals 8,389 reported bike accidents, 6,248 injuries, and 11 fatalities, a four-year trajectory that shows no sign of reversing.
This report examines where accidents are concentrated, when they peak, what behaviors cause them, and how the epidemic of hit-and-run drivers compounds every other danger cyclists face. For injured cyclists and their families, this data is not just a statistic. It is evidence of a system that continues to fail the most vulnerable people on Chicago's dangerous roads.
Chicago Bike Accident Data at a Glance: 2022 Through 2025
Four Years of Rising Bike Accidents in Chicago
The numbers tell a story that Chicago's cycling community has felt for years: the roads are getting more dangerous, and the pace of that change is accelerating. In 2022, the city recorded 1,686 bike accidents. By 2025, that number had climbed to 2,465, a 46.2% increase over just four years. What makes this trend particularly alarming is its consistency. There was no correction year, no plateau, no sign that the problem had peaked. Every single year set a new record.
The jump from 2023 to 2024 was the steepest single-year increase in the dataset, adding 364 accidents in twelve months, a rise of 18.8%. That year also saw hit-and-run accidents surge by 120 incidents, a 22.2% spike. By 2025, the growth rate had slowed somewhat to 7.1% year over year, but at 2,465 total accidents, the volume was higher than it had ever been. Injuries tracked the same curve exactly, rising from 1,256 in 2022 to 1,836 in 2025.
The one metric moving in the right direction is the fatality rate per accident. In 2022, cyclists were killed at a rate of 0.24% per reported accident. By 2025, that figure had fallen to 0.08%, a 66.7% improvement. This may reflect better emergency response times, higher helmet adoption, or infrastructure changes on specific corridors. But with accident volumes still climbing, the absolute number of people being hurt shows no sign of declining.

| Year | Accidents | Injuries | Fatalities | Hit-and-Runs | YOY Change |
|---|---|---|---|---|---|
| 2022 | 1,686 | 1,256 | 4 | 497 | Baseline |
| 2023 | 1,937 | 1,451 | 2 | 541 | +14.9% |
| 2024 | 2,301 | 1,705 | 3 | 661 | +18.8% |

Chicago's Most Dangerous Roads for Cyclists (2022 Through 2025)
N. Milwaukee Ave is not just the most dangerous road for cyclists in Chicago, it is in a category of its own. The diagonal arterial recorded 329 bike accidents and 253 injuries over the four-year study period, averaging more than 82 accidents per year. Its diagonal path through Wicker Park, Logan Square, and Avondale creates complex intersection geometry that generates consistent conflict between drivers and cyclists. One rider was killed there during the study period.
N. Clark St ranks second with 274 accidents and 214 injuries, and N. Damen Ave follows at 175 accidents. What makes Damen notable is that despite recording roughly half the accident volume of Milwaukee, it also recorded a fatality. Volume does not always predict severity, and that distinction matters for anyone planning a route through the city.
The Halsted corridor deserves attention as a system, not just two separate roads. N. Halsted St and S. Halsted St together recorded 318 accidents, more than any road except Milwaukee. Cyclists who commute along this corridor north to south are navigating one of the city's highest-risk environments for a sustained stretch. W. North Ave tells a different story: 47 of its 123 accidents (38.2%) involved a driver who fled the scene, the highest hit-and-run concentration among high-volume corridors. On that road, the danger is not just collision risk. If you are hit, there is better than a 1 in 3 chance the driver will not stop.
N. Elston Ave and N. Pulaski Rd both recorded average injury rates above 0.81 per accident, among the highest in the dataset. These are roads where accidents tend to be serious. A Chicago bicycle accident attorney can help document and pursue claims when negligent drivers cause harm on these corridors.
Cyclist Fatalities and Injuries in Chicago
Eleven cyclists were killed on Chicago roads between 2022 and 2025, and the story behind those deaths is more complicated than the headline number suggests. The per-accident fatality rate has improved significantly, falling from 0.24% in 2022 to just 0.08% in 2025. If you are struck today, your odds of surviving that accident are meaningfully better than they were three years ago. But that improvement is being masked by a volume problem: more cyclists are being struck than ever before, and the total number of people injured keeps rising regardless of the per-accident rate.
The injury picture is particularly telling when broken down by type. Incapacitating injuries, those that leave a cyclist physically unable to function normally, held relatively stable across the four years: 182 in 2022, 172 in 2023, 179 in 2024, and 179 in 2025. That stability is meaningful. But non-incapacitating injuries, the broken bones, concussions, lacerations, and soft tissue damage that require treatment and recovery time, surged 39.9% from 881 to 1,233. This is the fastest-growing injury category in the dataset, and it represents a large and growing population of cyclists who have been hurt enough to need medical care, lost wages, and potentially legal representation.
Fatalities are also distributed in ways that challenge assumptions about when cycling is most dangerous. October and November each recorded 2 deaths, tying August for the most in any single month, despite accounting for far fewer total accidents. Autumn conditions, lower light levels, wet leaves on road surfaces, and a driver population less alert to cyclists after summer, appear to create disproportionate fatal risk even as overall accident counts decline. When a crash on a Chicago road causes a death, the family of the victim may have grounds to pursue a wrongful death claim against the responsible driver.
The bottom line: Per-accident survival odds have improved, but more cyclists are being struck than ever. Volume growth is erasing the safety gains.
Chicago Hit-and-Run Bike Accidents: A Growing Crisis
Chicago has a hit-and-run epidemic. In 2025, a driver struck a Chicago cyclist and fled the scene 694 times. That is 694 people left in the road, some of them seriously hurt, by drivers who made a deliberate choice not to stop. It amounts to nearly 1 in 3 bike accidents for the year. And it is not a new problem that has suddenly emerged. The number has risen every year since 2022, from 497 to 541 to 661 to 694, a 39.6% increase over four years that has outpaced the growth in total accidents.
When you look at which types of accidents produce the highest flee rates, a pattern emerges. "Improper Overtaking or Passing" is the worst offender: 49.0% of those accidents involved a driver who fled. That means a driver who passed a cyclist illegally was more likely than not to leave the scene. W. North Ave tells a similar story at the road level, where 38.2% of all bike accidents involved a hit-and-run. At locations with unknown or absent traffic controls, flee rates climb above 41%. These numbers suggest that hit-and-runs are not random events driven by panic. They are predictable outcomes in environments where drivers perceive low accountability.
The legal and practical implications for injured cyclists are significant. When a driver flees, the injured person loses the ability to exchange insurance information, gather identifying details, and in many cases cannot even describe the vehicle. But that does not mean the legal options disappear. Uninsured motorist coverage and other remedies may be available. Document everything immediately, vehicle color, direction of travel, any partial plate numbers, any witnesses, and contact a Chicago bicycle accident attorney as early as possible.
Hit-and-Run Accidents by Year: 2022 Through 2025
Up 39.6% in four years. Hit-and-run bike accidents grew faster than total bike accidents, meaning drivers are choosing to flee at an accelerating rate, not simply in proportion to rising volume.
When Do Bike Accidents Happen in Chicago? We Found Seasonal Patterns and Hidden Dangers
Chicago's bike accident data has a seasonality that anyone who rides the city's roads will recognize instantly. The warm months bring more cyclists out, and more cyclists on the road means more accidents. August is the single most dangerous month in the dataset at 1,201 accidents over four years, with July (1,099) and September (1,126) close behind. May through October together account for roughly 82.8% of all bike accidents, concentrated into just half the calendar year.
But volume alone does not tell the full safety story. October and November are where the data gets interesting and sobering. Each month recorded 2 fatalities across the study period, matching August despite having far fewer total accidents. The fatality rate per accident in those months is substantially higher than the summer peak. What is happening in fall is not more accidents, it is more lethal ones. Drivers who spent all summer sharing the road with cyclists become less attentive as riding season winds down. Light levels drop. Roads become slicker. The mismatch between driver expectations and cyclist presence creates conditions where accidents are less frequent but more deadly.
The same dynamic appears at the daily level. Dusk is the single most lethal lighting condition in the dataset. Clear weather at dusk produced 2 fatalities in just 219 accidents, a rate of 0.91%, nearly four times the overall average. The transition from daylight to darkness is the most perceptually challenging period for drivers detecting cyclists, and the data bears that out in the most consequential way possible. The 5 to 8 PM window in late summer and fall is when this risk is highest.
Weekday accident peaks align with commuting: Monday through Friday between 7 to 9 AM and 4 to 6 PM show the highest concentrations. Sunday accidents cluster between noon and 6 PM, reflecting recreational riders. Late Saturday and Sunday nights between midnight and 2 AM show elevated accident rates consistent with impaired driving.
Monthly Bike Accident Distribution (2022 Through 2025 Combined)
What Is Actually Causing Chicago Bike Accidents
The most common classification in Chicago's bike accident database is "Unable to Determine," and that fact alone tells you something important about the problem. Of 8,389 reported accidents, 3,293 (39.25%) have no identified cause. This is not primarily a data quality issue. It is a direct consequence of the hit-and-run epidemic. When a driver flees the scene before police arrive, investigators cannot establish what behavior caused the accident. Every hit-and-run that goes unsolved becomes another entry in the "unable to determine" column, and that column now represents the single largest cause category in the city's own records.
When cause can be identified, the data points clearly to a single dominant behavior: drivers who do not yield. Failing to Yield Right-of-Way accounts for 2,165 accidents, 25.81% of all incidents, and is linked to 1,777 injuries and 1 fatality. Every one of those accidents involved a moment when a driver had the legal obligation to stop or give way, and did not. This is not mechanical failure or road hazard. It is a decision, and it is the most harmful decision drivers make around cyclists in Chicago.
The next tier of causes reveals a pattern of drivers who are simply not paying attention to the rules of the road. Failing to Reduce Speed accounts for 289 accidents and 1 fatality. Disregarding Traffic Signals accounts for 284 accidents and 1 fatality. Improper Turning accounts for 281 accidents and produces a particularly high injury rate relative to accident count, because a driver turning into a cyclist generates a direct impact rather than a glancing one. Together, these three causes represent nearly 900 additional accidents that could have been prevented if drivers had observed basic traffic law.
Improper Overtaking and Passing stands out for a different reason. It only accounts for 239 accidents, but 49.0% of those accidents, nearly half, involved a driver who fled. Drivers who illegally pass cyclists are not just creating risk in the moment. They are also the drivers most likely to leave an injured person in the road.
Safety Recommendations for Chicago Cyclists, Families, and Policymakers
These accidents are not inevitable. The data reveals specific, identifiable, preventable failures by drivers, by infrastructure, and by enforcement systems. Here is what the numbers demand in response.
- Avoid or use extra vigilance on Milwaukee Ave, Clark St, Damen Ave, and Halsted St
- Use high-visibility lighting and reflective gear during the 5 to 8 PM dusk window, especially in fall
- If struck in a hit-and-run, document vehicle color, direction of travel, and any witnesses immediately
- Peak danger window is June through September, ride defensively and plan your routes
- Protected bike lanes, signal timing, and turn restrictions are needed urgently on Milwaukee, Clark, Damen, and Halsted
- Leading cyclist intervals at high-volume intersections directly address the number one cause: failing to yield
- Expanded camera networks and mandatory stop enforcement to deter hit-and-run flight, which now affects 1 in 3 accidents
- Dusk-specific lighting upgrades and seasonal safety campaigns for the September through November window
- Document everything at the scene, photos, witnesses, officer badge numbers, vehicle descriptions
- Seek medical attention immediately, even if injuries feel minor, some worsen over days
- Hit-and-run victims may have access to uninsured motorist coverage even when the driver is unknown
- Contact a qualified Chicago bicycle accident lawyer before speaking with any insurance company
Injured in a Chicago Bike Accident? Know Your Legal Rights
The data in this report is not just a public health record. The accidents analyzed here involve specific, identifiable driver behaviors: failing to yield, running red lights and stop signs, illegal passing, and fleeing the scene. Each of these constitutes driver negligence, and negligence is the legal foundation of a personal injury claim.
If you or a family member has been struck by a vehicle while riding in Chicago, you have legal rights that deserve to be protected. This is true even if the driver fled. Uninsured motorist coverage, underinsured motorist coverage, and other legal remedies may be available to hit-and-run victims. The insurer's first settlement offer is almost never the full amount you are entitled to, and without legal representation, most injured cyclists accept far less than their claim is worth.
The attorneys at Briskman Briskman & Greenberg have spent decades fighting for injured Chicagoans. If a negligent driver caused your accident, our team can investigate the incident, identify all liable parties, deal with insurance companies on your behalf, and pursue the full compensation you deserve for medical bills, lost wages, pain and suffering, and more.

Frequently Asked Questions About Chicago's Bike Accident Problem
What are the most dangerous roads for cyclists in Chicago?
Based on 2022 through 2025 City of Chicago crash records, N. Milwaukee Ave is the most dangerous road for cyclists with 329 accidents, 253 injuries, and 1 fatality over four years. N. Clark St (274 accidents) and N. Damen Ave (175 accidents, 1 fatality) rank second and third. N. Halsted St and S. Halsted St together account for another 318 accidents, making Halsted one of the city's most persistently dangerous corridors. W. North Ave has the highest hit-and-run rate, 38.2%, among high-volume roads.
Why are Chicago bike accidents increasing every year?
Chicago bike accidents have risen every single year from 2022 through 2025, a 46.2% total increase. The steepest jump came between 2023 and 2024, when accidents rose 18.8% in a single year. Contributing factors include rising cycling activity, persistent driver behaviors such as failing to yield and disregarding traffic signals, inadequate infrastructure on high-volume corridors, and a hit-and-run rate of nearly 1 in 3 accidents in 2025. Volume growth has outpaced any safety improvements made during this period.
What should I do if I'm hit by a car while riding my bike in Chicago?
Call 911 and seek medical attention even if your injuries seem minor. Document as much as possible at the scene: photos of the vehicles, road conditions, your bike, and any visible injuries, along with witness names and the responding officer's badge number and report number. If the driver fled, note the vehicle's make, color, and direction of travel. Do not give a recorded statement to any insurance company before consulting with a Chicago bicycle accident attorney. Even hit-and-run victims may have legal remedies through uninsured motorist coverage.
What is the most common cause of bike accidents in Chicago?
"Unable to Determine" is technically the most common classification (39.25% of accidents), but this largely reflects the hit-and-run problem: when drivers flee, cause cannot be established. Among identifiable causes, Failing to Yield Right-of-Way is the clear leader, responsible for 2,165 accidents and 25.81% of all incidents, linked to 1,777 injuries over the four-year study period. Together these two categories cover nearly two-thirds of all reported bike accidents in Chicago.
Can I still file a claim if the driver who hit me fled the scene?
Yes. Hit-and-run victims in Chicago are not without legal recourse. Your own auto insurance policy may include uninsured motorist coverage that applies even when the at-fault driver is unknown. If you do not own a vehicle, you may still be covered under a household family member's policy. In some cases where surveillance footage or witnesses identify the driver, a direct negligence claim may also be possible. A Chicago hit-and-run accident attorney can evaluate which remedies apply to your specific situation.
