Car Insurance in Illinois

State minimum coverage requirements

Under Illinois Insurance Code 625 ILCS 5/7-601, all Illinois drivers must maintain the following minimum coverage:

• $25,000 bodily injury per person
• $50,000 bodily injury per accident
• $20,000 property damage per accident

Driving without insurance in Illinois results in a minimum fine of $500 for a first offense and $1,000 for a second offense within five years. Your vehicle registration will be suspended, and you must pay a $100 reinstatement fee plus provide proof of current insurance to have it restored. SR-22 filing is not automatically required for a first offense conviction but may be required if you receive court supervision rather than a conviction, or for a third or subsequent offense. If you cause an accident while uninsured, your license can be suspended for a minimum of three months, and reinstatement requires additional fees and proof of coverage. Illinois operates an electronic insurance verification system that allows law enforcement and the Secretary of State to confirm coverage status at traffic stops and registration renewals.

Is Illinois a no-fault state?

No. Illinois is an at-fault state.

The driver determined to be at fault for causing an accident bears financial responsibility for the resulting damages. Injured parties file claims against the at-fault driver's liability coverage rather than their own policy. Illinois applies a modified comparative fault rule with a 51 percent threshold. If you are found 50 percent or less at fault, you can recover compensation from the other driver reduced by your share of fault. If you are 51 percent or more at fault, you cannot recover anything from the other party. This rule has a practical consequence for everyday driving: even a minor degree of shared fault reduces your compensation proportionally. If you cause an accident that exceeds your liability limits, you are personally responsible for the gap, and Illinois courts can enforce civil judgments through wage garnishment and liens on property. The $25,000 per person bodily injury minimum can be consumed quickly in a serious accident, which is why carrying limits above the state minimum is strongly recommended.

What the state minimum covers and does not cover

Illinois's 25/50/20 liability minimum covers only injuries and property damage you cause to other people. It does not cover:

• Damage to your own vehicle from a collision
• Your own medical expenses after an accident
• Losses caused by an uninsured or underinsured driver
• Theft, weather events, or vandalism to your vehicle

Uninsured motorist coverage in Illinois

Illinois insurers are required to offer uninsured and underinsured motorist coverage, and drivers may reject it in writing. UM coverage pays for your medical expenses and vehicle damage when an at-fault driver has no insurance, while UIM coverage covers the gap when an at-fault driver has insurance but not enough to pay all of your losses. Illinois has a meaningful percentage of uninsured drivers on its roads, particularly in the Chicago metro area where traffic volume and accident rates are elevated. Without UM coverage, your only option after being hit by an uninsured driver is pursuing a personal lawsuit against someone who, by definition, does not carry assets backing their driving. Carrying UM and UIM at matching limits to your liability coverage is a widely recommended baseline for Illinois drivers.

How credit affects your rate in Illinois

Illinois permits insurers to use a credit-based insurance score as one factor when pricing auto policies. The check is a soft inquiry and does not affect your credit report or credit score. Illinois law requires insurers to notify you if credit information results in an adverse action on your policy, giving you the opportunity to review your credit report for inaccuracies. If your credit has improved since your last renewal, shopping new quotes across multiple carriers is worthwhile because carriers weight credit differently and improvements in your score can reduce your premium even without any change in your driving record.

Recommended coverage levels

Most advisors recommend carrying at least 100/300/100 liability in Illinois, which provides $100,000 per person and $300,000 per accident in bodily injury coverage along with $100,000 for property damage. The state minimum property damage limit of $20,000 does not reflect the replacement cost of many newer vehicles. If your vehicle is financed or leased, your lender will require collision and comprehensive coverage in addition to liability. For vehicles you own outright, compare the annual cost of collision and comprehensive against ten percent of your car's current market value. Adding uninsured motorist coverage at matching limits to your liability policy provides important protection given Illinois's at-fault system and the number of uninsured drivers on state roads.

How insurers determine your rate in Illinois

Illinois insurers use your driving record, zip code, vehicle type, age, annual mileage, and credit-based insurance score to calculate your premium. The Chicago metropolitan area consistently produces some of the highest auto insurance premiums in the state due to accident frequency, vehicle theft rates, and medical costs in urban markets. Downstate Illinois and rural areas carry considerably lower base rates. At-fault accidents and moving violations typically affect your rate for three to five years. Because each insurer weights these factors differently, comparing quotes from multiple carriers at renewal is the most reliable way to find the most competitive rate for your specific profile.

SR-22 requirements in Illinois

An SR-22 in Illinois is a certificate filed by your insurer with the Secretary of State confirming you carry at least the state minimum liability coverage. You may be required to maintain an SR-22 after a DUI conviction, after driving without insurance, or after certain serious traffic violations. The requirement typically lasts three years from the triggering event, and your license remains suspended until the SR-22 is on file. If your policy lapses during the SR-22 period, your insurer must notify the Secretary of State immediately, which reinstates your suspension. Not all insurers handle SR-22 filings, so drivers who need one should specifically look for carriers that serve the non-standard auto insurance market in Illinois.
