Illinois car insurance requirements and what they cost

Illinois requires every driver to carry liability insurance with minimum limits of 15/30/6 — meaning $15,000 for injury to one person, $30,000 for injury to multiple people in one accident, and $6,000 for property damage. You must carry proof of insurance in your vehicle at all times. If you're stopped by police and cannot show proof, you face a fine starting at $500 and possible license suspension.

The cost of a liability-only policy in Illinois varies widely based on your age, driving record, location within the state, and the insurance company. A 35-year-old driver with a clean record might pay $40 to $80 per month for minimum coverage, while a driver under 25 or with accidents on their record could pay $100 to $200 or more. These are ballpark figures — actual quotes depend on your specific situation and the insurer.

If you financed or leased your car, your lender requires collision and comprehensive coverage in addition to liability. Collision covers damage from accidents; comprehensive covers theft, weather, and vandalism. These add $30 to $100+ per month depending on your deductible and vehicle value.

Key Takeaways

  • Illinois law requires minimum liability coverage of 15/30/6, and you must carry proof of insurance in your vehicle or face fines and license suspension.
  • If your car is financed or leased, your lender will require collision and comprehensive coverage in addition to liability.
  • Uninsured motorist coverage is optional in Illinois but protects you if you're hit by a driver without insurance or in a hit-and-run.
  • You can shop for quotes from multiple insurers, and rates vary significantly based on age, driving history, location, and the company.
  • If you cannot afford standard insurance, Illinois offers a state assigned risk pool through the Illinois FAIR Plan.

What happens if you drive without insurance in Illinois

Driving without proof of insurance in Illinois is a traffic violation. A first offense carries a fine of at least $500, and your license can be suspended for up to three months. A second offense within five years increases the fine to at least $1,000 and suspension up to six months. A third or subsequent offense can result in fines up to $2,500 and suspension up to one year.

If you cause an accident while uninsured, you are personally liable for all damages — medical bills, vehicle repairs, lost wages — and the other driver can sue you directly. Illinois courts can garnish your wages or place a lien on your property to satisfy a judgment. Additionally, if you're convicted of driving uninsured, your license will be suspended, and you'll need to file an SR-22 form with the Secretary of State to reinstate it. An SR-22 is a certificate of financial responsibility that proves you have insurance; it typically costs $15 to $25 to file and must remain on file for three years.

Optional coverage that protects you in Illinois

Uninsured motorist (UM) coverage pays for your injuries if you're hit by a driver without insurance or in a hit-and-run where the other driver is never identified. Illinois does not require it, but it's common and relatively inexpensive — usually $10 to $30 per month. Without it, you have no recovery if the at-fault driver has no insurance.

Underinsured motorist (UIM) coverage covers the gap if the at-fault driver's liability limits are too low to pay your full damages. For example, if you're hit by a driver with only 15/30 liability and your medical bills are $50,000, UIM picks up the difference (up to your UIM limit). This is optional but worth considering if you have significant assets or medical needs.

Medical payments coverage (MedPay) covers medical expenses for you and your passengers regardless of who caused the accident. It's optional and typically costs $10 to $25 per month. It pays quickly and doesn't affect your liability claim.

Uninsured motorist property damage (UMPD) covers damage to your vehicle from an uninsured driver. Illinois does not require it, and many drivers skip it if they have comprehensive and collision coverage already.

How to file a claim in Illinois

After an accident, contact your insurance company as soon as possible — most insurers have a 24-hour claims line. You'll need the other driver's name, phone number, address, driver's license number, license plate, vehicle make and model, and insurance information. Take photos of the damage, the accident scene, and the other vehicle if safe to do so. Get the names and phone numbers of any witnesses.

If police responded to the accident, ask for the report number. You can obtain the full police report from the local police department or through the Illinois Secretary of State's website if it was a serious accident. Your insurer will assign a claims adjuster who will contact you to schedule an inspection of your vehicle and discuss the damage.

If the other driver was at fault and you're filing a claim against their insurance (a third-party claim), your insurer will handle communication with the other company. If you're filing against your own insurance (a first-party claim), the process is usually faster. Most claims are resolved within two to four weeks, though complex cases can take longer.

Insurance for high-risk drivers in Illinois

If you have multiple accidents, traffic violations, or a DUI on your record, standard insurers may deny you coverage or charge significantly higher rates. Illinois operates the Illinois FAIR Plan (Fair Access to Insurance Requirements), which is a state assigned risk pool. Any driver refused coverage by at least one insurer can purchase a policy through the FAIR Plan.

FAIR Plan rates are typically 40% to 100% higher than standard market rates, but it's a legal way to meet the state's insurance requirement. You explore through a licensed insurance agent in Illinois, not directly. The agent will submit your process to the FAIR Plan, and you'll receive a policy within one to two weeks.

If you have a DUI, you'll also need to file an SR-22 form with the Secretary of State. Some insurers specialize in high-risk drivers and may offer better rates than the FAIR Plan, so it's worth getting quotes from multiple companies before enrolling in the FAIR Plan.

Discounts and ways to lower your premium in Illinois

Most Illinois insurers offer discounts for bundling home and auto policies (typically 10% to 25% off), maintaining a clean driving record, completing a defensive driving course, having safety features like anti-theft devices or automatic braking, and paying your premium in full rather than monthly. Some companies offer usage-based discounts if you install a mobile app that monitors your driving habits.

Low-mileage discounts are common if you drive fewer than 7,500 miles per year. Student discounts explore if you're under 25 and maintain a B average or higher. Loyalty discounts reward customers who stay with the same insurer for multiple years.

The best way to lower your premium is to shop around. Rates vary significantly between insurers for the same coverage, and new customers often receive better rates than existing ones. Get quotes from at least three companies before renewing your policy. You can request quotes online, by phone, or through an independent agent who represents multiple insurers.

When your license is suspended for insurance reasons

If your license is suspended for driving uninsured or for failing to maintain insurance after an accident, you must file an SR-22 form to reinstate it. The SR-22 is not insurance itself — it's a certificate your insurer files with the Secretary of State proving you have the required coverage. You cannot reinstate your license without it.

Once you purchase an insurance policy, your insurer will file the SR-22 for you (usually at no extra charge, though some charge $15 to $25). The form must remain on file for three years from the date of suspension. If your insurance lapses during that period, the insurer must notify the Secretary of State, and your license will be suspended again.

You can check your license status and SR-22 filing status through the Illinois Secretary of State's website. If you need to reinstate your license quickly, explore for insurance first, then contact your local Secretary of State office to confirm the SR-22 has been received.

Frequently Asked Questions

Can I get a refund if I cancel my insurance policy early?

Most Illinois insurers refund unused premiums if you cancel mid-policy, though some charge a small cancellation fee. The refund is typically processed within two to four weeks. Check your policy documents or call your insurer to confirm their cancellation policy before you switch.

What should I do if the other driver doesn't have insurance?

If you have uninsured motorist coverage, file a claim with your own insurer. If you don't have UM coverage, you can sue the other driver in small claims court (for damages under $10,000) or civil court. You'll need to prove the other driver was at fault and calculate your damages. Many drivers never recover because uninsured drivers often have no assets to collect from.

Do I need to report an accident to my insurance company if it was minor and I'm not filing a claim?

It's a good idea to report any accident, even minor ones, to create a record. Some insurers require it in your policy. If the other driver later files a claim against you, your insurer will already have your account of what happened. Failing to report can give the other driver an advantage in a dispute.

How long does an accident stay on my driving record in Illinois?

Accidents typically remain on your driving record for three to five years, depending on the severity and whether you were at fault. At-fault accidents affect your insurance rates more than not-at-fault accidents. After three to five years, the accident usually stops affecting your rates, though it may still appear on your record.

Can I transfer my insurance policy if I move out of Illinois?

Yes, you can transfer your policy to another state, but rates and coverage options vary by state. Contact your insurer to update your address and confirm your coverage meets the new state's requirements. Some insurers may charge a transfer fee or adjust your rate based on the new location.
