Power, financial strength ratings from AM Best and complaint data from the National Association of Insurance Commissioners (NAIC).

What is full coverage car insurance in Illinois?

Full coverage car insurance isn’t a single policy – it’s a bundle of protections that offer more complete financial security. It generally includes liability coverage (required in most states), along with collision and comprehensive insurance. Collision pays to repair or replace your car after an accident, while comprehensive covers non-collision damage such as theft, hail, fire or vandalism.

Because it protects your own vehicle in addition to others, full coverage typically comes with a higher premium than minimum liability insurance. It can be especially worthwhile if you drive a newer vehicle, have an auto loan or lease, or own a car that would be expensive to repair or replace.

Auto insurance premiums vary significantly from city to city, so drivers need to be sure they’re getting the best deal. Insure.com has done the research for you. Get more information on auto insurance rates by city below.

How do you find the best car insurance rates in Illinois?

Shopping around for coverage is a great way to make sure you are getting the best rates on your auto insurance.

“It is extremely important to make sure you start off with an apples-to-apples comparison,” says Tim Bottini, a Country Financial insurance agent based in St. Louis. That means checking:

• The same liability limits
• The same deductibles
• The same coverage types

For example, if one quote shows 25/50/25 in liability coverage and another shows 50/100/100, the lower price may simply reflect lower protection – not a better deal. Many agents recommend at least 50/100/100, and higher limits may make sense depending on your income and assets.

You can also lower your premium by:

• Maintaining a strong credit score
• Avoiding tickets and accidents
• Bundling home and auto insurance with the same carrier

Which companies have the cheapest car insurance for seniors in Illinois?

Senior drivers in Illinois typically pay higher car insurance premiums than most other age groups, although teens still face the highest rates overall.

The cheapest car insurance companies for seniors in Illinois include:

• GEICO: $1,345 per year ($112 per month)
• Travelers: $1,506 per year
• Progressive: $1,592 per year

Insurance companies often charge seniors more because premiums reflect broader risk patterns, including claim frequency and age-related factors such as slower reaction times or changes in vision. However, many seniors can still secure competitive rates by maintaining a clean driving history, limiting annual mileage and taking advantage of mature driver or safe driver discounts.

The chart below highlights the average car insurance premiums for senior drivers in Illinois.

Which companies have the cheapest car insurance for young drivers in Illinois?

While rates start to drop for teen drivers as they become young adults, they still pay slightly higher rates than more experienced drivers. According to our data, Travelers is the cheapest insurer for drivers in their early 20s with an average premium of $2,346 a year or $196 per month.

GEICO was the second cheapest insurer at $2,570 and Auto Club Group (AAA) will insure a young driver in Illinois for $2,665 a year.

Rates will continue to drop (assuming a clean driving record) as drivers hit their late 20s and move into their 30s. The chart below shows the average premiums for young drivers.

Which companies have the cheapest car insurance for teen drivers in Illinois?

In Illinois, Erie Insurance offers the most affordable coverage for teen drivers, with average premiums starting at $4,680 annually or $390 per month.

Because teens have less driving experience, insurers classify them as higher-risk policyholders.

“Teenagers and seniors are riskier drivers, so they often pay more for auto insurance than other policyholders in different age groups,” says Chong Gao, director of product management R&D at Mercury Insurance. “For teenagers, the lack of driving experience is a significant factor that impacts their rates; younger drivers with little experience behind the wheel tend to pay higher insurance premiums.”

Auto Club Group (AAA) follows at $4,969 per year or $414 per month, while Country Financial rounds out the top three at $5,044 annually.

The table below shows average teen car insurance premiums in Illinois:

Why the cheapest company may vary by driver

The lowest average rate doesn’t always mean the lowest quote for you. Car insurance is highly personalized, and insurers price policies differently based on risk.

Key factors that affect your premium include:

• Driving record
• Credit score (in most states)
• Age and marital status
• Vehicle make and model
• ZIP code and local risk levels

Age is one of the biggest pricing factors. For example, adding a teen to a policy can significantly increase premiums because teens are the least experienced drivers and are more likely to be involved in accidents and file claims.

“Teen drivers are statistically more likely to be involved in accidents due to their lack of driving experience and tendency to engage in risky behaviors like speeding,” says Eliezer Zupnick, founder of East Leads Group LLC. “Teens are involved in three times as many auto accidents per mile compared to drivers aged 20 and up, making them a high-risk category for insurers.”

Parents can help offset higher costs by asking about good student discounts, insuring a less expensive vehicle or adjusting coverage if the car’s value is low.

What is the average cost of car insurance in Illinois?

The average cost of car insurance in Illinois is $1,938 a year.

Car insurance rates vary widely from state to state because insurers base premiums on overall risk trends, including claim frequency, repair costs, state regulations and local accident data. Even within the same state, drivers can see different quotes depending on their driving history, age, vehicle and ZIP code.

The chart below displays the average rate in Illinois for a 40-year-old driver with 100/300/100 coverage and a $500 collision and comprehensive deductible driving a Honda Accord LX.

Which cities and ZIP codes in Illinois are the most expensive for car insurance?

Chicago has the highest car insurance rates in Illinois, with average premiums reaching $2,801 per year across its most expensive ZIP codes.

Insurers use ZIP code data to assess localized risk factors, including traffic density, crime rates and exposure to severe weather. Urban areas with higher accident frequency or vehicle theft claims typically have the highest premiums.

According to our analysis of city and ZIP code data, the following areas are the most expensive in Illinois for car insurance:

Which Illinois cities and ZIP codes are the cheapest for car insurance?

When it comes to cheap car insurance in Illinois, these ZIP codes have the most affordable coverage. The area around Normal has the lowest premiums in Illinois with an average premium of $1,583.

How location in Illinois impacts car insurance rates

Your ZIP code can significantly influence what you pay for car insurance in Illinois. Insurers look at local risk factors such as accident rates, traffic density, repair costs and weather-related claims when setting premiums.

“States that have a higher rate of severe weather that damages cars or helps cause accidents will typically have higher rates,” says Gao.

Because insurers weigh these location-based risks differently using their own pricing models, quotes can vary widely even for drivers with similar profiles living in different parts of the state.

Who has the cheapest car insurance for high-risk drivers in Illinois?

Traffic violations and accidents can drive up your car insurance premiums because insurers often classify drivers with tickets or accidents as higher risk.

For instance, a speeding ticket can increase the average premium to $2,806 and may impact your rates for up to three years. An at-fault accident generally has a greater effect, raising the average cost of coverage to approximately $3,046.

A DUI is considered a serious offense and typically results in the largest premium increase, with average rates climbing to $3,486.

The table below illustrates the average rate increases following common driving violations.

Minimum car insurance requirements in Illinois

To legally drive in Illinois, you’re required to carry at least 25/50/20 in liability car insurance. This minimum coverage pays for bodily injury and property damage you cause to others in an accident.

But state minimum limits are designed to meet legal requirements – not necessarily to fully protect your finances. In a serious crash, medical bills and repair costs can quickly exceed those limits. If that happens, you could be responsible for the remaining balance out of pocket.

That’s why many insurance experts suggest carrying higher limits, such as 100/300/50, to better protect your assets, income and long-term financial security.

Final thoughts on the best and cheapest car insurance in Illinois

The best car insurance in Illinois depends on your budget, driving profile and coverage needs. GEICO delivers strong overall value by combining competitive pricing with high customer satisfaction and financial stability.

That said, the cheapest insurer for the average driver may not be the cheapest for you. Factors like your age, driving history, vehicle and ZIP code all influence your final quote, which is why comparing multiple insurers is key.

To get the best rate in Illinois, compare quotes from at least three companies, review coverage limits (not just price) and take advantage of discounts such as bundling, safe driver, telematics or good student savings. A few minutes of comparison shopping can lead to significantly lower premiums without sacrificing coverage.
