The Role of Bad Weather in Chicago Traffic Accidents: Legal Implications

Feb 27, 2026

Chicago drivers face some of the most unpredictable weather in the country. From heavy snowstorms and black ice to torrential rain and dense fog, dangerous conditions contribute to thousands of crashes across Cook County every year.

At Coffman Law, we frequently represent victims injured in weather-related car accidents. One of the most common misconceptions we hear is:

“It was snowing, so no one is at fault.”

That is not how Illinois law works.


 

Weather Does Not Excuse Negligence Under Illinois Law

Even in poor conditions, drivers have a legal duty to operate their vehicles safely. Under Illinois law, motorists must adjust their driving based on road and weather conditions.

That means:

  • Slowing down during snow and ice
  • Increase following distance in heavy rain
  • Using headlights in low visibility
  • Avoiding sudden braking on slick roads

If a driver fails to adjust to conditions and causes a crash, they may be legally responsible — even if bad weather played a role.

An experienced Chicago car accident lawyer at Coffman Law can evaluate whether negligence occurred.


 

The Duty of Care in Chicago Weather-Related Accidents

Illinois drivers owe a duty of reasonable care to others on the road. When conditions worsen, the level of caution required increases.

For example:

  • Driving 55 mph on a clear day may be reasonable.
  • Driving 55 mph during a snowstorm on I-94 may be negligent.

A driver who loses control because they were traveling too fast for conditions can still be held liable in a Chicago personal injury claim.


 

Common Weather-Related Crash Scenarios in Chicago

 

  1. Rear-End Collisions on Icy Roads

    Failure to maintain a safe following distance often causes winter crashes. Even on black ice, the trailing driver is typically responsible.

  2. Hydroplaning on Wet Expressways

    Hydroplaning frequently occurs when drivers travel too fast for rain-slick pavement. Speed remains a key liability factor.

  3. Multi-Vehicle Pileups

    Chain-reaction crashes are common on I-90, I-290, and Lake Shore Drive during snow squalls. Liability depends on each driver’s conduct.

  4. Failure to Clear Snow and Ice

    Drivers are responsible for maintaining clear visibility. Snow flying off vehicles can cause severe accidents.

If you were injured in one of these situations, contact a Chicago personal injury attorney at Coffman Law to protect your rights.


 

Proving Liability in a Weather-Related Car Accident

To recover compensation in Illinois, you must prove:

  1. The driver owed you a duty of care
  2. The driver breached that duty
  3. The breach caused the crash
  4. You suffered damages

Evidence may include:

  • Police reports
  • Weather data records
  • Traffic camera footage
  • Vehicle black box data
  • Witness statements
  • Accident reconstruction analysis

Insurance companies often blame “the weather” to avoid paying claims. At Coffman Law, we investigate thoroughly to prove driver negligence.


 

Damages Available in a Chicago Weather-Related Accident

Victims may be entitled to compensation for:

  • Past and future medical bills
  • Out of pocket expenses
  • Lost wages
  • Loss of earning capacity
  • Pain and suffering
  • Property damage
  • Wrongful death damages

If a loved one was killed in a winter or weather-related accident, our firm can assist with a wrongful death claim under Illinois law.
