Illinois car insurance requirements start with a 25/50/20 liability policy: at least $25,000 in bodily injury coverage per person, $50,000 per accident, and $20,000 for property damage. Every policy must also include uninsured motorist coverage at the same bodily injury limits. Driving without coverage can cost you a fine above $500, a three-month license suspension, and a separate registration suspension triggered by the state’s electronic verification system.
The Minimum Coverage You Must Carry
The liability minimums are set by 625 ILCS 5/7-203 and have not changed in decades.1Illinois Department of Insurance. Auto Insurance Shopping Guide – Section: Required Auto Insurance Coverages Liability only pays for other people’s losses when you are at fault. If you rear-end someone, your bodily injury coverage handles their medical bills and lost wages, and your property damage coverage pays to fix their car. Your own injuries and your own vehicle are not covered by any of it.
On top of liability, Illinois requires every auto policy to include uninsured motorist (UM) bodily injury coverage at matching 25/50 limits. UM pays your medical expenses and lost wages when you are hit by a driver who carries no insurance or by a hit-and-run driver who cannot be identified. Insurers must also make uninsured motorist property damage coverage available for private passenger vehicles, up to the vehicle’s actual cash value or the policy limit, whichever is less, with a maximum deductible of $250.2Illinois General Assembly. Illinois Code 215 ILCS 5/143a
If you buy liability limits higher than 25/50, your insurer must automatically set UM bodily injury limits to match unless you reject the higher UM amount in writing.3Illinois General Assembly. Illinois Code 215 ILCS 5/143a-2 You cannot reject the minimum UM coverage itself.
Underinsured motorist (UIM) coverage is separate. It applies when the at-fault driver has insurance but not enough to cover your losses. Illinois only requires UIM when your UM limits exceed the 25/50 minimum.3Illinois General Assembly. Illinois Code 215 ILCS 5/143a-2 If you carry only the minimum UM, UIM is not mandatory. If you buy higher UM limits, your policy must include UIM equal to those higher limits.
Proof You Must Keep in the Vehicle
You have to carry evidence of insurance in your vehicle at all times and show it to any officer who asks during a traffic stop.4FindLaw. Illinois Code 625 ILCS 5/7-602 A paper card works. So does displaying the information electronically on a phone or tablet. The statute also recognizes binders and premium receipts.
Under rules adopted by the Secretary of State, valid proof must include your insurer’s name, the policy number, effective and expiration dates, the named insured, and the vehicle’s year, make, and VIN. Failing to produce this information can result in a citation even if you actually have valid coverage, because the officer has no way to confirm the policy on the spot.
Penalties for Driving Without Insurance
The penalty structure under 625 ILCS 5/3-707 varies with your history and with whether you can show current coverage at your court date.
First Offense, Current Coverage at Court
If you have never been convicted of driving without insurance before and you show up to court with proof that your vehicle is now insured, the fine drops to $100 and you receive court supervision instead of a conviction.5Illinois General Assembly. Illinois Code 625 ILCS 5/3-707 You have to maintain coverage throughout supervision and prove it when supervision ends.
Standard First and Second Offenses
Without that current-coverage option, a conviction brings a fine of more than $500 and no more than $1,000.5Illinois General Assembly. Illinois Code 625 ILCS 5/3-707 The wording matters: $500 is the threshold, not the floor. Every conviction also triggers a three-month driver’s license suspension and a $100 reinstatement fee after the suspension ends.6Illinois Secretary of State. Driver’s License Reinstatement Fees Driving while suspended for this offense extends the suspension by another six months.
Third and Later Offenses
A third or later conviction becomes a business offense with a mandatory $1,000 fine.5Illinois General Assembly. Illinois Code 625 ILCS 5/3-707 At that point the state also requires you to file an SR-22 certificate of financial responsibility and maintain it for at least three years.7Illinois Secretary of State. Financial Responsibility (SR-22) Insurance An SR-22 is a form your insurer files directly with the state confirming you carry at least the required coverage. If the policy lapses during the three years, your insurer notifies the Secretary of State and your license is suspended again. SR-22 policies typically cost more than standard coverage.
Causing a Crash While Uninsured
Driving uninsured and causing an accident is treated as a Class A misdemeanor. A third or subsequent conviction under this provision carries a mandatory $2,500 fine on top of any jail sentence.5Illinois General Assembly. Illinois Code 625 ILCS 5/3-707
How the State Finds You Without a Traffic Stop
The Secretary of State runs an electronic program that checks every registered vehicle for active liability coverage at least twice a year, working with a third-party vendor connected to every insurer writing auto policies in Illinois.8Illinois Secretary of State. Mandatory Insurance
If the first check cannot confirm coverage, the system rechecks 30 days later. If that second check still finds no policy, the registered owner receives a suspension letter and has 30 days to prove, through their agent, that coverage existed on the date of the initial check. Owners who cannot prove it lose their vehicle registration. Reinstating registration requires active coverage and a $100 fee.8Illinois Secretary of State. Mandatory Insurance
You can lose your registration this way without ever being pulled over. A short lapse while switching insurers can be enough to start the process if your old carrier reports the cancellation before the new policy takes effect.
If You Drive for Uber or Lyft
Personal auto policies generally exclude commercial activity, including rideshare driving. Illinois handles rideshare separately under the Transportation Network Providers Act (625 ILCS 57), which sets its own insurance requirements tied to each phase of the ride cycle, including $1,000,000 in liability coverage from the moment you accept a ride through drop-off. If you drive for a rideshare company, meeting the standard 25/50/20 personal policy alone does not satisfy what the TNC Act requires, and your personal insurer may deny claims that arise while you are logged into the app.
Why the Minimums Often Are Not Enough
The 25/50/20 numbers have not kept pace with the cost of medical care or vehicle repair. If you cause a serious accident, your insurer pays up to the policy limit and you are personally responsible for the rest, which can reach your savings, your home equity, and your future earnings.
The reverse is also true. If someone carrying only the minimum hits you, their $25,000 per-person limit may cover a fraction of your actual costs. That is where UM and UIM coverage above the state minimum does the real work. The cost difference between minimum limits and significantly higher limits is often a few hundred dollars a year.
