Most people assume that if you crash without hitting another car, it is your fault and you have no legal options. That is not always true. Single-vehicle accidents in Chicago can happen for reasons that have nothing to do with the driver, and Illinois law allows injured victims to pursue compensation in many of these situations.
A single-vehicle accident is any crash that involves only one car. You might hit a guardrail, a tree, a utility pole, or roll over on a highway. You might slide off the road in bad weather or swerve to avoid a hazard. These accidents cause serious injuries every year across Chicago, and in many cases, someone other than the driver is responsible.
What Causes Single-Vehicle Accidents in Chicago?
Not every single-vehicle crash is caused by driver error. Several outside factors can lead to a serious accident even when the driver is doing everything right.
Poor Road Conditions
Chicago roads are notorious for potholes, uneven pavement, and crumbling shoulders. When the city or a road maintenance contractor fails to repair a known hazard, they can be held liable for accidents that result. Poorly designed intersections, missing guardrails, and inadequate drainage that causes flooding or ice buildup are also grounds for a claim.
If a pothole or road defect caused your accident, you may have a claim against the City of Chicago or the Illinois Department of Transportation (IDOT). These government liability claims have specific notice requirements and shorter filing deadlines, so acting quickly is important.
Defective Vehicle Parts
A tire blowout, brake failure, faulty steering, or malfunctioning accelerator can cause a driver to lose control and crash. When a defective vehicle component causes an accident, the manufacturer, distributor, or auto repair shop may be liable under Illinois product liability law.
Common defective parts involved in single-vehicle accidents include:
- Tires that blow out due to manufacturing defects
- Brake systems that fail to stop the vehicle
- Steering components that lock up or disconnect
- Airbags that fail to deploy or deploy unexpectedly
- Accelerators that stick in the open position
Dangerous Weather
Chicago winters bring ice, snow, and reduced visibility that contribute to single-vehicle crashes. While drivers are expected to adjust their driving to weather conditions, the city and state have a responsibility to maintain roads during storms. Failure to salt, plow, or treat dangerous roads can make a government entity partially liable.
Other Drivers
Sometimes a single-vehicle accident is actually caused by another driver who leaves the scene. If another car cuts you off, forces you off the road, or causes you to swerve and crash, that driver is at fault even though the vehicles never made contact. These are sometimes called “phantom driver” accidents.
Proving a phantom driver caused your crash can be challenging, but it is not impossible. Dashcam footage, witness testimony, and physical evidence like tire marks can help establish that another vehicle was involved.
Construction Zone Hazards
Chicago always has construction zones on its highways and city streets. When construction crews fail to properly mark hazards, maintain detour routes, or secure equipment, drivers can lose control and crash. The construction company responsible for the zone can be held liable.
Who Is Liable in a Single-Vehicle Accident?
Depending on what caused the crash, several parties could be responsible for your injuries:
Government entities, The City of Chicago, Cook County, or IDOT may be liable if poor road design, missing signs, or inadequate maintenance caused the accident. Claims against government entities in Illinois must follow the Court of Claims Act, which has strict notice and filing requirements.
Vehicle manufacturers, If a defective part caused you to lose control, the manufacturer can be held liable under strict product liability. You do not need to prove negligence, only that the product was defective and caused your injuries.
Auto repair shops, If a mechanic performed faulty repairs that led to brake failure, tire blowout, or steering problems, the repair shop can be held liable.
Other drivers, A driver who ran you off the road or created a hazard is at fault, even if they left the scene.
Property owners, If overhanging trees, debris, or hazards from private property spilled onto the road and caused your accident, the property owner may share liability.
Construction companies, Improperly maintained work zones, missing signage, and unsecured equipment can all make a construction contractor liable.
Can You Get Compensation If You Were Partially at Fault?
Yes. Illinois uses a modified comparative fault system. You can recover compensation as long as you are not more than 50% responsible for the accident. Your award is reduced by your percentage of fault.
For example, if you were driving slightly over the speed limit when you hit a massive pothole that the city knew about but did not fix, a court might find you 20% at fault and the city 80% at fault. If your damages totaled $200,000, you would receive $160,000.
This is why it is critical to have an attorney investigate the full circumstances of your single-vehicle accident. What looks like a simple one-car crash on the police report often involves negligence by other parties that only a thorough investigation can uncover.
What Compensation Is Available?
If another party is liable for your single-vehicle accident, you may be entitled to:
- Medical expenses, Emergency room visits, surgery, hospitalization, medication, physical therapy, and future medical care
- Lost wages, Income lost during recovery and reduced future earning capacity
- Pain and suffering, Physical pain, emotional distress, anxiety, and diminished quality of life
- Property damage, Vehicle repair or replacement costs
- Disability, Long-term or permanent impairment from injuries like traumatic brain injury or spinal cord damage
Single-vehicle accidents often result in severe injuries because there is no other vehicle to absorb the impact. Hitting a fixed object like a concrete barrier or tree at highway speed frequently causes traumatic brain injuries, spinal cord injuries, and multiple fractures.
What to Do After a Single-Vehicle Accident in Chicago
Taking the right steps after a single-vehicle crash protects both your health and your legal rights.
- Call 911 and get a police report. Even though no other vehicle was involved, you need an official record of the accident. Tell the officer exactly what happened, including any road defects, weather conditions, or other vehicles that contributed to the crash.
- Get medical attention immediately. Do not assume you are fine just because you walked away from the crash. Internal injuries, concussions, and soft tissue damage often do not show symptoms for hours or days.
- Document the scene. Photograph the road conditions, any defects or hazards, vehicle damage, your injuries, weather conditions, and the surrounding area. If a pothole or road defect was involved, take close-up photos with a reference object for scale.
- Preserve your vehicle. Do not repair your car right away. The vehicle itself is evidence. A mechanical expert may need to inspect it to determine whether a defective part contributed to the crash.
- Report to your insurance company. Notify your insurer about the accident, but keep your statement brief and factual. Do not speculate about fault or accept blame.
- Contact a Chicago car accident lawyer. An attorney can investigate the crash scene, obtain maintenance records for the road, hire mechanical experts to inspect your vehicle, and identify all potentially liable parties.
Insurance Coverage for Single-Vehicle Accidents
Even if no other party is liable, your own insurance may cover your injuries and damages:
- Collision coverage pays for vehicle damage regardless of fault
- Medical payments coverage (MedPay) covers medical expenses for you and your passengers regardless of fault
- Uninsured motorist coverage may apply if a phantom driver caused your crash and left the scene
If another party is liable, their insurance or your uninsured/underinsured motorist coverage may apply depending on the circumstances.
Why You Need a Lawyer for a Single-Vehicle Accident Claim
Insurance companies treat single-vehicle accidents differently. Because no other driver was visibly involved, adjusters are quick to blame the driver and deny claims. They may argue that you were speeding, distracted, or simply lost control.
An experienced Chicago car accident lawyer can:
- Investigate whether road conditions, vehicle defects, or other drivers contributed to your crash
- Hire accident reconstruction experts and mechanical engineers
- Obtain city maintenance records, construction zone plans, and weather data
- File claims against government entities within their strict deadlines
- Negotiate with insurance companies that want to minimize your payout
Do not assume a single-vehicle accident means you have no case. Many of these crashes involve negligence by parties that only a thorough investigation can identify.
