A CTA bus or train accident claim runs on a different clock and a different set of rules than an ordinary Chicago car accident case, and missing that difference is one of the fastest ways to lose an otherwise valid claim. The standard two-year window injury victims are used to doesn’t apply here. Against the Chicago Transit Authority, the deadline to file suit is one year, and it comes with a separate notice requirement that most people have never heard of until it’s too late to fix.
This guide explains the CTA’s unique legal deadlines, the elevated duty of care Illinois law imposes on public transit as a common carrier, and how a CTA claim differs from a standard car accident case against a private driver.
The CTA’s One-Year Deadline: 70 ILCS 3605/41
Most Illinois personal injury claims run on a two-year statute of limitations. Claims against the Chicago Transit Authority do not. Under 70 ILCS 3605/41, part of the Metropolitan Transit Authority Act that created and governs the CTA, a lawsuit against the Authority must be commenced within one year from the date the cause of action accrued. The statute also requires that written notice of the claim be given to the CTA. If that notice isn’t filed as the statute requires, the civil action can be dismissed regardless of how strong the underlying injury claim is.
This is a separate and distinct deadline from the one-year notice provision that applies to claims against the City of Chicago and other units of local government under the Local Governmental and Governmental Employees Tort Immunity Act. The CTA has its own dedicated statute because it’s a special transit district, not a general unit of local government, and that statute has its own specific requirements for both the content of the notice and the timing of the lawsuit itself. Treating a CTA claim like a standard one-year government claim, without confirming the specific notice content 70 ILCS 3605/41 requires, is a common and entirely avoidable way to lose a valid case on a technicality that has nothing to do with fault.
Common Carrier Duty of Care: A Higher Standard, Not an Absolute One
Illinois law holds common carriers, including CTA buses and trains, to a higher standard of care toward their passengers than the ordinary reasonable-care standard that applies between two private drivers. Because passengers must rely entirely on the carrier’s safe operation and maintenance of its own equipment, common carriers owe what Illinois courts describe as the “highest degree of care” consistent with the practical operation of the transit system.
But this heightened duty is not unlimited, and the CTA can and does successfully defend claims by pointing to the boundaries of that duty. In Krywin v. Chicago Transit Authority, 238 Ill. 2d 215 (2010), the Illinois Supreme Court held that the CTA’s highest-duty-of-care standard did not override the state’s separate “natural accumulation” rule, meaning the CTA generally has no duty to remove natural accumulations of snow and ice from a train platform, even though it owes passengers the highest degree of care in other respects. What this means practically is that a CTA claim needs to be evaluated carefully against the specific legal theory involved: a sudden, unsafe stop while a passenger is standing is a very different legal question than a fall on ice that accumulated naturally on an outdoor platform.
Roughly 900,000 rides happen across CTA’s bus and rail network on an average weekday, which means the range of incidents that produce real injury claims is broad, from a single passenger’s fall to a multi-vehicle collision involving a CTA bus and several other cars. Regardless of scale, the same combination of elevated duty of care and strict, CTA-specific procedural deadlines applies to every one of them.
To put the higher standard in context: in an ordinary two-car crash, a driver is held to the standard of reasonable care that an average careful person would exercise under similar circumstances. A common carrier operating a bus or train full of passengers who have no ability to control the vehicle themselves is held to a meaningfully higher standard, reflecting that total dependence. This distinction matters when evaluating whether the CTA’s conduct fell short, but as Krywin illustrates, it doesn’t erase every other defense available under Illinois law.
Common Types of CTA Bus and Train Accident Claims
Sudden stops and abrupt braking
CTA buses and trains carry many standing passengers, especially during rush hour, and an unnecessarily abrupt stop, whether from driver inattention, following too closely, or reacting late to a hazard, can throw standing passengers into poles, seats, or each other. The common carrier duty of care applies directly to how the vehicle is operated.
Door-related injuries
Passengers caught in closing doors, whether train doors or bus doors, sustain a recurring category of injury that raises questions about whether the doors’ sensors and operator procedures functioned as designed.
Platform gap and boarding/alighting falls
The gap between a train car and the platform, uneven boarding surfaces, and inadequate lighting at stations all factor into falls that happen while getting on or off a train.
Collisions involving CTA vehicles and other traffic
A CTA bus involved in a collision with another vehicle, a pedestrian, or a cyclist raises standard negligence questions about the bus operator’s conduct, in addition to the common carrier duty owed to the bus’s own passengers.
Maintenance and equipment failures
Defective seating, malfunctioning wheelchair lifts, or poorly maintained flooring surfaces can each form the basis of a claim tied to the CTA’s duty to maintain safe equipment for its passengers.
Why Evidence Disappears Fast in CTA Claims
CTA buses and rail cars are equipped with surveillance cameras, and station platforms typically have their own camera systems as well. This footage is often the single most important piece of evidence in a CTA claim, showing exactly how a sudden stop happened, how a fall occurred, or how a door closed on a passenger. It’s also routinely overwritten or deleted on a retention cycle that can run as short as thirty to sixty days. A written request to preserve footage, sent to the CTA promptly after the incident, is one of the most time-sensitive steps in one of these cases, arguably more urgent even than the one-year notice deadline itself, since notice can still be filed within a year while footage may already be gone within weeks.
Witness identification is similarly time-sensitive. Other passengers who saw what happened are far easier to locate and willing to provide a statement in the days after an incident than months later, and the CTA’s own incident report, taken by a supervisor or the operator, becomes part of the official record that both sides will rely on.
Wrongful Death Claims Involving the CTA
When a CTA-related incident results in a death, the claim proceeds under Illinois’s Wrongful Death Act, 740 ILCS 180, but still has to satisfy the CTA’s own separate notice and one-year filing requirements under 70 ILCS 3605/41 in addition to the Wrongful Death Act’s own procedural rules. Because two different statutory frameworks apply at once in a fatal CTA case, coordinating the notice deadline, the wrongful death filing requirements, and the identification of every eligible beneficiary under the Act requires careful, prompt legal attention rather than the more forgiving timeline a standard fatal car accident claim might allow.
Comparative Negligence Still Applies
Even with the CTA’s elevated duty of care toward passengers, Illinois’s modified comparative negligence rule under 735 ILCS 5/2-1116 still governs how fault is allocated. A passenger who was, for example, standing in a clearly marked no-standing area, or who ignored a posted warning, could see their own recovery reduced by their share of fault, and barred entirely if found 51% or more at fault. The CTA’s own insurance defense counsel will look for exactly this kind of comparative fault argument, which makes thorough documentation of exactly what happened, not just that an injury occurred, important from the outset.
Hypothetical Example: The Notice Deadline That Almost Ended a Claim
The following is a hypothetical scenario for illustration only, not a description of an actual client or case outcome.
Imagine a rider injured when a CTA bus braked hard to avoid a car that ran a red light, throwing her into a stanchion and fracturing her wrist. She initially assumes she has two years to pursue a claim, the same as she’d have against the driver of the car that ran the light. Ten months after the crash, she consults an attorney who identifies that her claim against the CTA itself, for the bus operator’s response to the hazard, falls under the one-year deadline and specific notice requirements of 70 ILCS 3605/41, not the standard two-year window. Filing the required notice and lawsuit in the following weeks preserves her claim against the CTA, a claim that would have been permanently lost had she waited even a few more months under the mistaken assumption that the ordinary two-year deadline applied.

Frequently Asked Questions
How long do I have to file a claim against the CTA?
One year from the date the claim accrued, under 70 ILCS 3605/41, along with a separate written notice requirement. This is significantly shorter than Illinois’s standard two-year personal injury deadline, so getting legal advice quickly after a CTA-related injury matters.
Does the CTA’s “highest duty of care” mean it’s always liable for a passenger injury?
No. The highest duty of care applies to how the CTA operates and maintains its vehicles and stations for passengers, but it doesn’t override every other legal doctrine, including the natural accumulation rule for snow and ice, as the Illinois Supreme Court confirmed in Krywin v. Chicago Transit Authority. Each claim still depends on the specific facts and legal theory involved.
What if I was standing when the bus or train stopped suddenly?
Standing passengers can still bring valid claims, particularly if the stop was unnecessarily abrupt given the circumstances. Whether comparative fault reduces the claim depends on specific facts, such as whether posted safety instructions were followed.
Is a claim against the CTA different from a claim against the bus driver personally?
CTA bus and train operators are typically CTA employees, so a claim for their on-the-job conduct is generally brought against the CTA itself as the employer, subject to the CTA’s specific notice and filing deadlines described above.
What if another driver, not the CTA, caused my injury while I was a CTA passenger?
You may have a standard negligence claim against that driver, subject to Illinois’s ordinary two-year statute of limitations, in addition to or instead of any claim against the CTA, depending on the facts of how the crash occurred.
What information does the notice to the CTA need to include?
Illinois notice statutes for public transit and government entities generally require specifics like the date, time, and location of the incident, a description of how it happened, and the nature of the injury. Because the exact content and delivery requirements matter and a defective notice can jeopardize the whole claim, this is not a form to fill out casually or from memory months after the fact.
Can I still sue the CTA if I was partly at fault?
Possibly, depending on your percentage of fault. Illinois’s modified comparative negligence rule allows recovery reduced by your own share of fault as long as you’re found less than 51% responsible, but being found equally or more at fault than the CTA bars recovery entirely.
If You Were Injured on a CTA Bus or Train
CTA claims involve a shorter deadline, a specific notice requirement, and legal doctrines that don’t apply to a standard car accident case. Getting the details right early matters more here than in almost any other type of Chicago accident claim.
