Cheapest Car Insurance in Illinois (June 2024)

Mercury is the cheapest car insurance company in Illinois overall, having the lowest minimum coverage rates. For certain types of drivers, American Family and Progressive might have lower rates.

If you’re looking to balance cost with service quality, MoneyGeek identified the best car insurance companies in Illinois.

In Illinois, the cheapest auto insurance companies for a minimum coverage policy are:

• Mercury: $274 per year
• Country Financial: $338 per year

The most expensive minimum coverage car insurance in Illinois is offered by Grange Insurance at roughly $707 per year, based on the companies MoneyGeek assessed. Car insurance that meets Illinois’ minimum car insurance requirements covers bodily injury liability, property damage liability and uninsured or underinsured motorist insurance.

Car insurance with minimum coverage only pays for the cost of damages or injuries you inflict on others in an accident. If you want protection that extends to your own vehicle, consider buying a full coverage policy that includes comprehensive and collision insurance.

Our study determined that the cheapest full coverage car insurance companies in Illinois are:

• American Family: $723 per year
• Travelers: $879 per year

Based on MoneyGeek's assessment, the most expensive full coverage policy in Illinois costs roughly $2,025 per year from Hanover.

Adding comprehensive and collision insurance to your auto policy will make your premium more expensive. In Illinois, for instance, opting for full coverage car insurance costs an average of $309 more than minimum coverage with the cheapest providers. A full coverage policy will financially protect you and your vehicle against damages caused by on-road accidents (hitting another car or object) and off-road incidents (vandalism, theft, fire and weather hazards).

How much car insurance you need will significantly influence your rates. Our study’s sample full coverage policy has the following liability limits:

• $100,000 bodily injury per person
• $300,000 bodily injury per accident
• $100,000 property damage per accident

To reduce your premium, you can lower your liability limits, remove comprehensive and collision insurance or raise your deductible. By doing so, however, you risk having insufficient coverage in the event of an accident.

You can get quotes online from different car insurance providers, but you must submit personal information for each, which can take up to 15 minutes. To compare rates across multiple companies, you must spend more time repeating this process.

Car insurance rates in Illinois are heavily influenced by age. On average, for teens, Progressive offers the most affordable prices, while American Family offers the most affordable prices for both young adults and seniors.

Among the teens, 19-year-olds pay the cheapest car insurance premiums because teens' rates decrease as they age. Auto-Owners ($1,609 per year) has the lowest rates for 19-year-old males in Illinois compared to its competitors.

Teens tend to pay less if they are added to a parent’s policy than if they buy separate insurance. In most cases, it is illegal for a teen under 18 to purchase auto insurance without a parent or guardian to co-sign. In Illinois, 16-year-olds save around $2,566 per year if they’re on a parent’s policy instead of buying their own policy.

Families in Illinois who want to reduce their insurance premiums may qualify for student discounts. Many companies, including Auto-Owners, Allstate, Progressive and State Farm, offer discounts for both students away from home and those with good academic performance.

Auto insurance companies found that those with poor credit are more likely to file claims, so they charge higher premiums to offset the costs of covering these drivers. Like many other states, Illinois does not ban insurers from considering credit-based insurance scores when calculating rates.

While improving your credit score gradually, you may seek companies that offer safe-driver or other discounts to help lower your insurance rate.

In Illinois, drivers are required to carry a policy that includes uninsured/underinsured motorist coverage along with bodily injury liability (BIL) and property damage liability (PDL). They also have the option to self-insure if they own at least 25 cars.

Illinois drivers are required to carry insurance that meets the minimum requirements for bodily injury liability, property damage liability and uninsured/underinsured motorist coverage. A minimum coverage policy is the cheapest insurance you can purchase, but it might offer inadequate coverage in case of an accident.

Additionally, SR-22 insurance is needed for drivers with serious traffic violations like reckless driving, driving without insurance, driving under the influence or driving with a suspended license, which typically leads to much higher rates than average drivers. SR-22 is a certificate filed by the insurer to prove the driver has the required insurance coverage in Illinois.

To ensure adequate financial protection in case of an at-fault accident, consider raising your liability limits to $100,000 in bodily injury for each person, $300,000 in bodily injury for each accident and $100,000 in property damage. If you finance or lease your car, you will likely be required to add comprehensive and collision insurance to your policy.

Comprehensive insurance covers the damage to your vehicle caused by vandalism, fires, natural disasters and weather-related incidents. Collision insurance pays for the damages to your car after hitting another vehicle or a stationary object.

Comprehensive and collision coverage is also recommended for drivers not financing or leasing a vehicle to have more excellent financial protection.

Unless you have more than 25 vehicles registered under your name, there’s no alternative to car insurance in Illinois. If you own more than 25 cars, you may qualify for self-insurance. It means you will assume all financial responsibilities in case of a vehicular accident, including the cost of repairs and medical treatments.

To obtain a self-insurance certificate from the Illinois Department of Insurance director, you must be financially capable of paying for claims as a minimum coverage policy would.

The director, however, may cancel your certificate of self-insurance if you fail to cover damaged vehicles in the event of an accident.
