The Ultimate Guide to Illinois Auto Insurance (2020)

Because Illinois is an at-fault state and because it does not have that many car accidents annually, its car insurance prices are slightly below the US average. Only in Chicago you’ll have to spend big bucks for your coverage. This is hardly surprising since Chicago is a densely populated city with many tourist visits annually and a significant number of large corporations having their headquarters there.

However, despite low Illinois auto insurance prices, we discovered that quotes from individual insurers vary greatly. For instance, for a 40-year-old driver in Chicago, our cheapest insurer requested $124 per month, while the most expensive charged $375. It’s even more surprising that the former performed better in departments such as customer service.

This means that little research can get you cheap, high-quality insurance. We did that research for you, so dive straight in to find the finest Illinois insurer for your needs.

The Overall Winner: ErieErie Auto Insurance Logo

Erie Auto insurance takes the first place in Illinois, despite the competition being fiercer than in any other state. It’s the combination of strong results in vital insurance metrics that make Erie such a good option. 

To start with the customer service, Erie scores full five stars in J.D. Power’s ranking for North-Central region. Furthermore, its NAIC ratio is 0.64. This indicates that Erie receives 36% fewer customer complaints than an average company of its size.

Additionally, Erie gets “A+” rating from AM Best, which confirms it’s a financially stable company, capable of paying customer claims. Finally, Erie is one of the most affordable insurers in the state.

Such strong performance across the board makes Erie the best auto insurance in Illinois. Its only downside is that it does not have an insurance app, meaning folks who prefer to do all the business online may want to check our number two and number three options.

Additionally, the company provides affordable automobile insurance in Illinois for all driver demographics. Auto-Owners also has a slick and highly rated mobile app. It allows you to pay bills, organize documents, track claims, and view and download proof of insurance.

However, the company has two significant downsides. First, Auto-Owners does not offer as many optional coverages as bigger insurers such as State Farm or Progressive. 

Second, Auto-Owners does not provide an online quote option. It prefers doing business exclusively through agents. Still, if you want cheap auto insurance, especially in Chicago where it will be easy to find an agent, Auto-Owners is worth the hassle.

Cheapest Car Insurance in Illinois (By City)

We gathered quotes from major insurers with full coverage limits to set the prices. Our reference vehicle was 2018 Honda Accord.


Chicago is the third most populous city in the US, with over 2.71 million people living in the town, and approximately 9,533,040 residing in the surrounding metropolitan area. It also attracts the highest number of tourists annually after New York. Just in 2018, Chicago had over 58 million visitors. 

Additionally, leading world companies such as Boeing, Allstate, and KraftHeinz, as well as prestigious universities, such as the University of Chicago and Northwestern University, all attract many workers and students to Chicago.car insurance price comparison in Chicago, IL

That’s why it doesn’t come as a surprise that the car insurance Chicago residents can buy is expensive. Still, our Illinois winner, Erie, is among the most affordable insurers in the Mud City. Progressive and Country Financial also offer reasonable rates, but the former gets low scores in customer service.


Aurora is a Chicago suburb with a total population of 200,965. Its nickname is “City of Lights” because it was one of the first US cities to adopt fully electric street lights in 1881. Aurora is also a place where you can visit architectural landmarks designed by Frank Lloyd Wright.car insurance price comparison in Aurora, IL

Auto insurance in Aurora, IL, is on average $44 cheaper monthly than in Chicago. Erie is the most affordable option, followed by Progressive. While Erie certainly deserves your attention, we would rank Country Financial over Progressive due to its more reliable customer service. We would also put Auto-Owners near the top of our list.


Rockford is the largest town in Illinois that’s not a part of the Chicago metropolitan area, and the third most populous city in the state overall. It is one of the leading cities in the US for furniture manufacturing. It’s also a place where the rock band Cheap Trick was formed.car insurance price comparison in Rockford, IL

Auto insurance in Rockford, IL, is $38 less expensive monthly compared to Aurora, which makes it the second least expensive city in our Illinois study. There’s plenty of affordable companies to choose from, including Nationwide, Progressive, and Erie. However, we would even stretch our budget and include Country Financial too, since it gets excellent results in the crucial categories.


Joliet is located 30 miles southwest of Chicago. It is the fourth most populous city in Illinois, with a total population of 147,433. It was traditionally a steel manufacturing town, but now it is commuters’ suburb, with many people working in Chicago and Aurora.car insurance price comparison in Joliet, IL

If you want cheap insurance but Chicago rates are just too high, consider moving to Joliet. You’ll pay $78 less for car insurance monthly on average. Erie is the most affordable and the best option in Joliet. Country Financial, although slightly more expensive, is the second best option. We also highly recommend Auto-Owners and The Hartford.


Naperville is located 28 miles west of Chicago. According to recent research, it’s one of the finest cities in the nation. It was ranked as the second best place to live in the US, according to Money’s 2016 research. It also recently took the award for the wealthiest city in the Midwest region, and the eleventh most affluent in the nation.Auto insurance price comparison in Naperville, IL

Despite Naperville being a prosperous city, its auto insurance is only $1 more expensive monthly on average than in Joliet. Erie, which offers the finest car insurance Illinois drivers can get, is also the most affordable option. 

Travelers, Progressive, and Country Financial, offer quite reasonable rates too. However, the latter is the only one out of these three that we can wholeheartedly recommend. We would also urge you to get an Auto-Owners quote too.


Springfield is the capital of Illinois and the city which hosts the state’s government. That’s why it does not come as a surprise that the State of Illinois is the city’s leading employer. Springfield is also the place where Abraham Lincoln spent 24 years of his life.car insurance price comparison in Springfield, IL

Auto insurance in Springfield, IL, is the cheapest in the state, with an average premium of $145. Almost all companies we tested offered protection for less than $200 per month, which is quite affordable for full coverage policy. 

Erie is the least expensive insurer and also the best in Springfield. We would also consider Country Financial, Travelers, and Auto-Owners.

Illinois Auto Insurance Laws

Comparative Negligence

Illinois uses a “modified comparative fault” system. Under this system, you must not be more than 50% at-fault to recover compensation for the damage you have suffered. As FindLaw notes, a judge or a jury calculate the percentages of the fault if the claim wasn’t settled first.

Additionally, the compensation rewarded will be reduced by your fault percentage. For insurance, if you were 20% at-fault, you would receive 80% of the amount that covers the property damage and injuries you have suffered.

Illinois Automobile Insurance Plan (ILAIP)

Similarly to Tennessee, Illinois car insurance system takes care of drivers who have a hard time finding coverage. If you have been turned down by an insurer in the past 60 days, you can enter the ILAIP program. If you do, you will be randomly assigned to an insurer licensed to operate in Illinois.

Every insurance company must participate in this program and take the number of high-risk drivers proportional to its market share. Once the government finds you an insurer, it’ll have an obligation to provide you with coverage for the next three years.

However, you’ll likely find much cheaper coverage if you continue shopping around after being rejected a couple of times. That’s why you should use this program only as a last resort.

Illinois Auto Insurance Minimum Requirements

These limits are the minimums any car insurance policy in IL must have:

  • Bodily Injury Liability – $25,000 per person/$50,000 per accident. This coverage pays for the injuries you’ve inflicted upon others in an accident you have caused (it may include other medical-related expenses too, like lost income or legal fees if the injured party sues you).
  • Property Damage Liability – $20,000 per accident. This covers any damage you caused to another person’s property in an at-fault accident. Usually, that property is their vehicle, but it can include personal belongings or stationary objects too.
  • Uninsured/Underinsured Motorist Bodily Injury – $25,000 per person/$50,000 per accident. This auto insurance coverage for Illinois drivers pays the medical expenses for injuries you suffered from being hit by a driver without car insurance coverage or with insufficient limits to pay your costs.

No-Fault Laws

Illinois is a “fault state,” meaning the liability insurance of the driver who caused the accident pays the medical expenses. We prefer it this way since no-fault states usually have much more expensive insurance. For instance, Michigan has the limitless PIP system, which drives its car insurance prices to the highest in the US.

And if you want coverage for physical injuries, you can always add MedPay to your Illinois vehicle insurance policy. It will provide immediate payments for you and your passengers. 

Sometimes, you can even rely on your regular health insurance. However, read the small print carefully, since some health insurance policies carry an exclusion for vehicle-related injuries.

Price Optimization

Price optimization is the practice of using non-underwriting criteria when determining rates. In other words, Illinois car insurance will rely on advanced software to calculate the highest price you are willing to pay for your coverage and try to charge you that price. Recent research indicates that about 45% of the most prominent US insurers use price optimization.

Despite some recent initiatives, Illinois authorities haven’t taken any action yet against the practice of price optimization. That’s why it’s prudent to shop around every now and then — you’re letting your insurer know you’re looking at the other offers. Knowing this, they’ll try to keep you as their customer by providing the best rates.

SR22 Insurance in Illinois

SR22 is a certificate that an insurance company has to submit to the local DMV after a severe violation. It serves as proof that your car insurance policy carries sufficient limits. You need an SR22 form after violations like driving under the influence, multiple smaller traffic infringements, or driving without a license. 

Once you enter the program, the government tracks your driving record, and after three years, you can buy regular auto insurance.

SR22 is itself cheap, but the insurance companies tend to charge 50% more if you require the certificate along with your policy.

How to Find the Cheapest Car Insurance in Illinois

Check the Discounts

The simplest way to get affordable coverage is to qualify for as many discounts as possible. This is quite easy if you are getting your quotes online. During each step, the system should prompt you to check discounts that fit your profile. If you are talking with an agent over the phone, make sure to remind them to list all available discounts.

Sometimes, it’s even worth taking proactive measures like enrolling in the programs where insurer tracks your driving, such as Nationwide’s SmartRide.

These kinds of discounts lower your rates by 40%, meaning you’ll be able to qualify for the cheapest insurance in Illinois.

Compare Quotes

Every insurance company has its methods of determining premiums. This means one driver may get very different prices depending on the insurer. That’s because insurance companies employ different market strategies, based on factors such as their recent profits.

Furthermore, regional companies tend to provide more affordable basic policies, while major players, such as Allstate and State Farm, offer many perks and benefits, but at a higher cost.

For all these reasons, the only way to get the low-cost auto insurance Illinois is to compare car insurance quotes from as many companies as possible. We suggest making a shortlist of at least five insurers that seem like the right fit for you. 

After that, obtain quotes from all of them and add a couple more if you don’t fancy the results. The whole process shouldn’t take more than a couple of hours.
