How to Report a Drunk Driver in Illinois

Every year, thousands of people are injured or killed in drunk driving crashes across Illinois and the United States. Despite decades of public awareness campaigns and tougher DUI laws, alcohol-impaired drivers continue to put innocent motorists, pedestrians, bicyclists, and motorcyclists at risk.

Reporting a suspected drunk driver may feel uncomfortable, but it can save lives. Law enforcement agencies throughout Illinois encourage drivers to report dangerous and impaired motorists before a serious crash occurs. Quick action by witnesses and other drivers often prevents catastrophic injuries and fatalities.

According to the National Highway Traffic Safety Administration (NHTSA), 11,904 people were killed in alcohol-impaired driving crashes in the United States in 2024. That means approximately one person died every 44 minutes in a drunk driving crash. About 30% of all traffic fatalities nationwide involved drunk drivers with blood alcohol concentrations (BACs) of .08 or higher.

“Drunk driving crashes are entirely preventable tragedies. When drivers choose to get behind the wheel while impaired, innocent people often suffer devastating injuries or lose their lives. Reporting suspected drunk drivers and holding negligent parties accountable can help make Illinois roads safer.” — John J. Malm, Naperville car accident lawyer

Drunk Driving Remains a Serious Problem in Illinois

Illinois continues to experience a substantial number of alcohol-related crashes each year. According to the Illinois Department of Transportation’s 2024 Crash Facts and Statistics report:

  • 20.4% of all fatal crashes in Illinois involved alcohol
  • 1,178 people were killed in motor vehicle crashes in 2024
  • More than one-third of fatally injured drivers tested had alcohol in their system
  • Alcohol impairment was also found among pedestrians, bicyclists, and motorcycle operators killed in crashes

These statistics highlight how dangerous impaired driving can be for everyone on the road, not just the intoxicated driver.

Signs of a Drunk Driver

Not every bad driver is intoxicated, but certain behaviors frequently indicate impairment. If you observe dangerous or erratic driving, you should take it seriously.

Common warning signs of a drunk driver include:

  • Swerving between lanes
  • Drifting over center lines
  • Driving significantly below the speed limit
  • Sudden braking
  • Wide turns
  • Failure to obey traffic signals
  • Driving without headlights at night
  • Tailgating
  • Nearly striking other vehicles
  • Erratic acceleration or deceleration
  • Driving on the shoulder
  • Stopping in traffic without reason

The Illinois State Police encourage drivers to report suspected impaired motorists when they observe unsafe driving behaviors.

How to Report a Drunk Driver in Illinois

If you believe another driver may be intoxicated, your first priority should always be your own safety. Do not attempt to confront the driver or force them off the road. Instead, safely contact law enforcement.

In Illinois, you can report a suspected drunk driver by calling:

  • 911 for emergencies or immediate danger
  • Local police departments
  • Illinois State Police
  • *999 from certain mobile phones for emergency assistance on highways

The Illinois State Police specifically advise drivers to provide the following information when reporting suspected drunk drivers:

  • Your location
  • The suspected driver’s location
  • Direction of travel
  • Vehicle description
  • License plate number if possible
  • Description of the dangerous driving behavior

The more details you can safely provide, the easier it may be for officers to locate the vehicle quickly.

What Information Should You Give Police?

When reporting a suspected drunk driver, dispatchers will usually ask several questions. Remaining calm and providing accurate information can help officers respond effectively.

Important details may include:

Vehicle Description

Try to identify:

  • Make and model
  • Vehicle color
  • Type of vehicle
  • License plate number
  • Distinguishing features or damage

Location Information

Provide:

  • Current roadway
  • Direction of travel
  • Nearby intersections or exits
  • Highway mile markers if possible

Dangerous Driving Behavior

Describe what you observed, such as:

  • Swerving
  • Speeding
  • Running red lights
  • Near collisions
  • Driving without headlights
  • Striking curbs or barriers

Police do not expect ordinary drivers to determine whether someone is legally intoxicated. Your role is simply to report dangerous driving behavior that may indicate impairment.

Stay Safe While Reporting a Drunk Driver

Drivers should never place themselves in danger while attempting to report an impaired motorist. It is important to avoid:

  • Speeding to keep up with the vehicle
  • Aggressive driving
  • Attempting to block the vehicle
  • Confronting the driver
  • Using a phone illegally while driving

If possible, use hands-free calling or have a passenger contact police. If you lose sight of the vehicle, do not continue pursuing it.

What Happens After You Report a Drunk Driver?

After receiving a report, law enforcement officers may attempt to locate the vehicle and observe the driver for signs of impairment. If officers witness traffic violations or suspicious driving behavior, they may conduct a traffic stop and DUI investigation.

A Reddit discussion involving law enforcement responses explained that officers often evaluate:

  • Driving behavior
  • Physical signs of intoxication
  • Field sobriety tests
  • Breath or blood alcohol testing

Not every reported driver will be arrested, but reports from concerned motorists often help police identify dangerous drivers before crashes occur.

Can You Get in Trouble for Reporting a Drunk Driver?

Many people hesitate to contact police because they worry they could get in trouble if the driver turns out not to be intoxicated. Generally, good-faith reports based on legitimate safety concerns do not create legal liability.

Experts consistently note that reporting suspected dangerous driving based on honest observations is not considered making a false police report. If you genuinely believe someone may be impaired or experiencing a medical emergency, contacting law enforcement is usually the responsible course of action.

Why Reporting Drunk Drivers Matters

Reporting impaired drivers helps protect:

  • Other motorists
  • Children and families
  • Pedestrians
  • Motorcycle riders
  • Road workers
  • Emergency responders

Drunk driving crashes often result in catastrophic injuries because intoxicated drivers may speed, ignore traffic signals, or fail to brake before impact. According to NHTSA, alcohol-impaired crashes continue to kill more than 11,000 people annually nationwide. Many of these tragedies are entirely preventable.

Common Injuries in Drunk Driving Accidents

Victims of drunk driving crashes often suffer severe and life-changing injuries, including:

  • Traumatic brain injuries
  • Spinal cord injuries
  • Broken bones
  • Internal organ damage
  • Burn injuries
  • Facial injuries
  • Neck and back injuries
  • Permanent disabilities
  • Wrongful death

Because impaired drivers frequently engage in reckless behavior, drunk driving crashes often occur at high speeds and with tremendous force.

What to Do After a Drunk Driving Accident in Illinois

If you are involved in an accident with a suspected drunk driver, you should:

  • Call 911 immediately
  • Seek medical attention
  • Cooperate with police officers
  • Obtain witness information
  • Take photographs if safe
  • Request a copy of the crash report
  • Avoid discussing fault with insurance companies
  • Contact an experienced Illinois car accident attorney

Police may conduct field sobriety tests or chemical testing if they suspect impairment. Criminal DUI charges may proceed separately from any civil injury claim.

Can Victims Recover Compensation After a Drunk Driving Crash?

Yes. Victims injured by drunk drivers may be entitled to compensation for:

  • Medical expenses
  • Lost wages
  • Pain and suffering
  • Disability
  • Rehabilitation costs
  • Emotional distress
  • Property damage

In some cases, punitive damages may also be available because drunk driving involves particularly reckless conduct. Illinois dram shop laws may also allow claims against bars, restaurants, or businesses that overserved visibly intoxicated individuals in certain circumstances.
