Cheap car insurance in Illinois

Minimum CoverageMinimum Limit
Minimum bodily injury liability$25,000/$50,000
Minimum property damage liability$20,000
Uninsured/underinsured motorist bodily injury$25,000/$50,000

Illinois car insurance laws mandate that drivers carry minimum liability coverage limits of 25/50/20 on their vehicle. Buying the state required limits to drive is definitely the cheapest way to go. But if you opt for the cheapest car insurance in Illinois, you are only covered for damage you do to other drivers’ cars and for others’ injuries. That means your insurer won’t pay for damage to your car or for your injuries if you cause an accident. Still, buying just the minimum coverage required is a good idea if you have an old car or don’t drive much.

It does cost more to buy more protection, but as you’ll see in the chart below, additional coverage is typically affordable. Increasing your insurance from the state minimum to full coverage with a $500 deductible costs, on average, $621 more, or about $50 a month. For higher liability limits, the extra cost is just $20a year.

Coverage limitsAverage annual rate
Liability Only – state minimum$383
Liability Only – 50/100/50 BI/PD$403
Full Coverage – 100/300/100 BI/PD $500 Comp/Collision deductible$1,004

What you need to know about car insurance in Illinois

The cheapest car insurance may not provide sufficient protection, so how much insurance should you buy? Bare-bones coverage may be a good choice if you have few assets or have an old car and don’t drive much. But if you have a home and investments, consider buying more insurance. If you don’t, you’re at risk for having your money and house taken to cover the cost of an accident. If you financed your car you will be required to get additional comprehensive and collision coverage.

Use our How Much Car Insurance Do You Need? tool to get a recommendation.


We recommend you buy more insurance than is required to legally drive a car in your state, especially if you have savings and assets. The more money you have, the more likely you are to be sued following a car accident should your insurance be insufficient to cover all the expenses. If your net worth is:

  • less than $50,000, choose at least 50/100/50
  • between $50,000 and $100,000, choose at least 100/300/100
  • more than $100,000, choose at least 250/500/100

If you’re leasing or financing your car, you must get coverage of 100/300/100 or higher.

Collision and comprehensive

Collision coverage pays for damage to your car after an accident that you cause. Comprehensive insurance pays to replace stolen cars and for damages from vandalism, flooding, hail, fire and animal strikes. If your car is:

  • less than 10 years old, you should strongly consider buying collision and comprehensive.
  • more than 10 years old, only buy collision and comprehensive if your car is worth $3,000 or more, if you couldn’t afford to replace your car if it’s wrecked, or if you just want more protection on your policy.

Collision costs an average of $459 annually in Illinois, comprehensive is $116, based on rate data. If you buy comp and collision, check our guide to choosing a deductible amount.

Uninsured/underinsured motorist

These are required in Illinois and should match the liability limits you choose. Uninsured motorist coverage and underinsured motorist coverage pays for damages if you’re hit by a driver with no insurance or a driver with coverage that’s insufficient to pay for your repairs and medical expenses.

Medical coverage (MedPay)

Medical payments coverage can help pay for the medical or funeral expenses of covered drivers and passengers after an accident, regardless of fault, up to $25,000. In most states, including Illinois, it’s an optional addition to your car insurance policy. MedPay does the following:

  • Covers you and your passengers’ medical expenses
  • Pays for expenses after health insurance limits are exceeded
  • Offers additional protection to insured drivers who are hit by a car while walking or biking

If you and your passengers:

  • Don’t have health insurance, or have a plan that doesn’t cover car accidents or has low limits, we recommend that you add medical coverage of at least $5,000 to your car insurance policy.
  • Do have health insurance, it’s still a good idea to have medical coverage if you want the best protection in your policy, as it can pay out after your health benefits are maxed out.

Gap insurance

If you don’t own your car outright and have an accident, gap insurance pays the difference between the cash value of your car and the current outstanding balance on your loan or lease.

  • If you’re financing your car, your car is less than one year old and you’ve put less than 20 percent down on it, you should buy gap insurance. If not, you don’t need gap insurance.
  • If you’re leasing your car, it’s a good idea to buy gap insurance if you aren’t already required to in your lease agreement.
  • If you own your car outright, you don’t need gap insurance.

Illinois car insurance laws

RoadsNumber of Fatal Accidents

Comparative negligence: Illinois has adopted a modified comparative negligence stance for the recovery of auto accident damages. This means that you may recover damages only if you are less than 50 percent at fault for the damages or injuries. And the amount you recover may be reduced in proportion to the degree that you are at fault. So, if you’re found to be 20 percent at fault, you can claim against the other party, but the third-party insurer may only pay 80 percent of your damages.

Reasons for cancellation: During the first 60 days of a new policy your Illinois car insurance company may cancel for almost any reason. After 60 days, there are still many reasons that the state allows your insurer to cancel or non-renew your policy. Read the full list on the Illinois Department of Insurance’s website.

Points system: Illinois has a unique way in which it applies points to your driving record. While the state does have a point schedule, the Driver Services Department goes by the number of moving violations you have been convicted of. Once you reach a certain point, the Department can assign you points to determine how long your license suspension will be.

Uninsured motorist penalties for Illinois: You may have to pay $500 to $1,000 in fines and your license and registration may be suspended.

Driving without a license: In Illinois driving without a license is a “petty offense”; you will have your license suspended and must pay a fine of up to $500. If your license expired over a year ago, the penalty rises to a Class B Misdemeanor — up to a $1500 fine and up to six months of jail time.

DUI stays on your record: DUI penalties in Illinois are harsh. A DUI stays on your record for your lifetime, with first-time offenders have their license suspended for a minimum of two years. Read our guide on DUI insurance if you’ve had a DUI.

Out-of-state/out-of-country drivers: Illinois law allows drivers to use an out-of-state license for 90 days before requiring an Illinois license.

No age restriction to own a car: Minors are legally allowed to buy and title a car in Illinois. Dealers and insurance companies may require a parent to buy or insure a car, however.

Electronic proof of insurance:Illinois allows drivers to show proof of insurance during a traffic stop on a smartphone. It is one of 31 states that does so.
