Car Accidents Caused by Brake Checking in Illinois
Key Takeaways
- The rear driver isn't always at fault. A driver who deliberately slams on the brakes without a legitimate reason may share responsibility, though Illinois still requires following drivers to keep a safe distance.
- You may recover even if you were tailgating. Under Illinois modified comparative negligence, you can recover if you're 50% or less at fault, with damages reduced by your share of blame.
- Evidence disappears quickly. Dashcam footage, surveillance video, witness accounts, and vehicle data can prove brake checking, so preserve them right away.
- You don't have to hit the brake checker to have a claim. If you swerved and crashed into something else, the brake-checking driver may still be liable for causing the crash.
Brake checking happens when a driver suddenly brakes to intimidate or retaliate against the vehicle behind them. If that conduct causes a crash, the lead driver may share responsibility, although Illinois also requires following drivers to maintain a safe distance.

What Is Brake Checking?
Brake checking generally means deliberately hitting the brakes to force a following driver to slow down, stop suddenly, or take evasive action. It is different from legitimate hard braking.
A driver may need to brake suddenly because:
- Traffic stopped ahead
- A pedestrian entered the road
- An animal crossed the roadway
- Another vehicle cut them off
- Road conditions created an emergency
Brake checking, by contrast, generally involves intentionally creating the sudden slowdown to intimidate or punish the driver behind.
Common situations include:
- Anger at someone for following too closely
- Road rage
- Retaliation after another driver passes or changes lanes
- Attempts to frighten another motorist
- In rare cases, attempts to cause an accident for fraudulent purposes
The reason the lead driver braked can therefore become one of the most important questions in the case.
Is Brake Checking Illegal in Illinois?
Illinois does not have a traffic statute specifically titled “brake checking.” However, intentionally using a vehicle in a dangerous manner can potentially violate other Illinois traffic or criminal laws depending on the facts.
For civil injury claims, the more important question is usually whether the driver's conduct was unreasonable and caused the collision. At the same time, Illinois law requires the following driver to maintain a safe distance.
Under 625 ILCS 5/11-710, a driver may not follow another vehicle more closely than is “reasonable and prudent,” considering vehicle speed, traffic, and roadway conditions. That means brake-checking cases often involve examining the conduct of both drivers rather than automatically assigning fault based only on which vehicle was hit from behind.
Who Is at Fault in a Brake-Checking Accident?
There is no automatic answer.
Rear-end crashes are often associated with the following driver because that driver has a duty to leave enough space to stop safely. But a lead driver who deliberately slams on the brakes without a legitimate reason may also be responsible for creating the danger.
The investigation may focus on questions such as:
- Did the lead driver have a legitimate reason to brake?
- Was the brake application sudden and unnecessary?
- Was the trailing driver following too closely?
- Was either driver speeding?
- Was either driver distracted?
- Had there been aggressive driving before the crash?
- Did the lead driver cut in front of the trailing vehicle before braking?
- Was there enough time for the trailing driver to react?
These details can completely change the liability analysis.
Is the Rear Driver Always at Fault?
No. Being the driver who rear-ended another vehicle does not automatically establish 100% fault.
Consider two different situations.
Situation 1: Normal Traffic Stop
A vehicle stops for a red light, and the driver behind it fails to stop. The trailing driver's failure to maintain sufficient distance may strongly support liability.
Situation 2: Intentional Brake Check
A driver becomes angry, cuts closely in front of another vehicle, and immediately slams on the brakes despite clear traffic ahead.
Here, the lead driver's actions may become a significant cause of the collision.
The point is not that brake checking automatically makes the lead driver 100% responsible. Rather, it can rebut the simple assumption that every rear-end accident was solely caused by the following driver.
What If You Were Following Too Closely?
You may still have a claim, but your compensation could be reduced. Illinois follows modified comparative negligence.
Under 735 ILCS 5/2-1116:
- If you are 50% or less at fault, you may still recover damages, but your compensation is reduced by your percentage of fault.
- If you are more than 50% at fault, you generally cannot recover.
For example, suppose your damages total $100,000.
If a jury finds that the brake-checking driver was 80% responsible and you were 20% responsible because you were following too closely, your recoverable damages may be reduced to $80,000.
This is why evidence about both drivers' actions is so important.
How Do You Prove Someone Brake Checked You?
Brake checking can be difficult to prove because the drivers often give completely different versions of what happened.
The lead driver may say:
“I had to stop suddenly.”
The trailing driver may say:
“They intentionally slammed on the brakes.”
Evidence can help determine which account is more credible.
Dashcam Footage
Dashcam video can be some of the strongest evidence in a brake-checking case.
It may show:
- The distance between the vehicles
- Whether the lead driver cut into your lane
- Whether traffic ahead required braking
- How suddenly the lead vehicle slowed
- Aggressive driving before the crash
Save the original footage immediately.
Traffic and Surveillance Cameras
Chicago streets and nearby businesses may have cameras that captured the collision or the events leading up to it.
Video may come from:
- Businesses
- Parking garages
- Homes
- Traffic systems
- Other vehicles
Some footage is automatically deleted or overwritten, so it should be investigated quickly.
Witnesses
A third-party witness may have seen the lead driver:
- Cut you off
- Gesture at you
- Brake repeatedly
- Drive aggressively
- Stop unexpectedly
Get names and contact details at the scene whenever possible.
Vehicle Data
Modern vehicles may contain electronic information concerning:
- Speed
- Braking
- Acceleration
- Throttle position
- Other events shortly before impact
Whether useful vehicle data exists depends on the vehicles and circumstances.
Police Reports
Tell the responding officer what happened.
If you believe the other driver intentionally brake-checked you, explain that clearly rather than simply describing the accident as “I hit the car in front of me.”
The police report is not necessarily the final decision on civil liability, but it can preserve important information from the scene.
What Should You Do Immediately After a Brake-Checking Crash?
How you respond after the accident can affect both your safety and your ability to prove what occurred.
Call 911
Report the accident and request police assistance. If the other driver has been acting aggressively, avoid confronting them.
Move Somewhere Safe
If the vehicles can safely be moved and traffic conditions allow, get away from active lanes.
Photograph the Scene
Take pictures of:
- Both vehicles
- Vehicle damage
- Skid marks
- Traffic signals
- Road layout
- Debris
- Weather conditions
- The surrounding area
Photographs can help reconstruct where and how the crash occurred.
Preserve Video Immediately
Do not assume a dashcam will save the recording permanently. Download and back up the original file as soon as possible.
Get Medical Attention
Some accident injuries are not immediately obvious. Seek appropriate medical evaluation if you experience pain or other symptoms, and explain accurately how the crash happened.
Avoid Arguments With the Other Driver
Brake checking can arise from road rage. Do not escalate the situation or try to force the other driver to admit what they did. Let police and the evidence address the fault.
Your case. Your future. Our full commitment.
What If the Driver Brake Checked You but You Avoided Hitting Them?
A brake-check can cause an accident even when the trailing vehicle never strikes the brake-checking vehicle.
For example, you may:
- Swerve into another lane
- Strike a guardrail
- Hit another vehicle
- Lose control
- Be struck by a vehicle behind you
The fact that there was no direct collision with the brake-checking vehicle does not necessarily eliminate that driver's potential responsibility.
The key issue is whether their conduct caused or contributed to the resulting crash. These cases can be harder to prove because vehicle damage may not directly connect the two cars, making dashcam footage and witness evidence particularly important.
What If Several Cars Are Involved?
Brake checking can cause chain-reaction crashes.
Suppose Vehicle A brake checks Vehicle B. Vehicle B stops suddenly, Vehicle C hits Vehicle B, and Vehicle D then crashes into Vehicle C.
Determining fault may require examining:
- Each driver's following distance
- Reaction time
- Speed
- Lane position
- Whether vehicles had already stopped
- Which impact occurred first
- The original reason traffic suddenly slowed
More than one driver may share responsibility under Illinois comparative negligence rules.
What Injuries Can Result From Brake-Checking Accidents?
Sudden braking and rear-end collisions can produce many different injuries depending on speed, vehicle size, and impact.
Possible injuries include:
- Neck injuries
- Back injuries
- Whiplash
- Herniated discs
- Head injuries
- Concussions
- Shoulder injuries
- Broken bones
- Knee injuries
- Facial injuries
- Internal injuries
A person may also experience delayed pain after initially believing they were uninjured. Get medical care based on your symptoms rather than assuming a low-speed collision cannot cause an injury.
What Compensation May Be Available?
If another driver's negligence or intentional dangerous conduct caused your injuries, an Illinois car accident claim may seek compensation for losses such as:
- Medical expenses
- Future medical treatment
- Lost wages
- Reduced earning capacity
- Pain and suffering
- Disability
- Disfigurement
- Property damage
The amount depends on the injuries, available evidence, insurance coverage, fault allocation, and other circumstances.
Are Punitive Damages Available for Intentional Brake Checking?
Possibly in an appropriate case, but they are not automatic.
Punitive damages are different from ordinary compensatory damages. They are intended to punish and deter especially wrongful conduct rather than simply reimburse an injured person for losses.
Intentional brake checking may create facts worth investigating, particularly when there is strong evidence of road rage or deliberate attempts to cause a collision. However, whether punitive damages are legally available depends on the evidence and applicable Illinois law.
It would be misleading to assume that every brake-checking accident automatically qualifies.
Can the Insurance Company Blame You Because You Rear-Ended the Other Car?
Yes. Expect the insurer to investigate whether you were:
- Following too closely
- Speeding
- Distracted
- Using your phone
- Driving too fast for conditions
- Paying attention before impact
The Illinois Department of Insurance explains that insurance companies investigate faults when handling third-party claims, and Illinois comparative negligence allows responsibility to be divided between drivers.
That is why simply telling an adjuster, “The other driver brake-checked me,” may not be enough.
Objective evidence is much stronger.
What If the Brake Checker Says You Were Tailgating?
Both things could potentially be true. A driver may have been following too closely and the front driver may have responded by intentionally brake checking.
Illinois comparative negligence allows both drivers' actions to be considered. Tailgating does not give another driver permission to deliberately create a crash. At the same time, brake-checking does not erase the following driver's duty to maintain a reasonable and prudent distance under Illinois law.
A strong case therefore focuses on the complete sequence of events instead of trying to reduce the accident to one action.
How Long Do You Have to File a Claim?
Illinois generally provides a two-year statute of limitations for personal injury lawsuits, although exceptions and shorter deadlines may apply depending on who caused the accident and other circumstances.
Do not wait until the deadline is approaching. Brake-checking cases can depend heavily on evidence that disappears quickly, particularly:
- Dashcam footage
- Business surveillance video
- Traffic video
- Witness memories
- Vehicle data
The practical evidence deadline can therefore arrive long before the legal filing deadline.
Frequently Asked Questions (FAQs)
Illinois does not have a stand-alone statute named “brake checking,” but intentionally dangerous driving can potentially violate broader Illinois traffic or criminal laws and can support civil liability when it causes an accident.
It depends on the evidence. The lead driver may be responsible for deliberately creating the hazard, while the rear driver may share fault for following too closely, speeding, or failing to pay attention.
Potentially. Rear-ending another vehicle does not automatically prevent recovery. Illinois comparative negligence allows recovery when your share of fault is 50% or less, with damages reduced according to your percentage of fault.
Dashcam footage can be particularly valuable because it may show the lead driver's movements, traffic conditions, following distance, and whether there was a legitimate reason to brake.
You may still have a claim if evidence establishes that the other driver's conduct caused the crash.
