Guide to auto insurance in Illinois

When getting an auto insurance quote for Illinois, it should meet at least the following insurance coverage or financial responsibility at a minimum:

20/40/15 – This is shorthand for the liability policy limits required which means you need a minimum coverage of:

  • $20,000 for death or injury to one person;
  • $40,000 for death or injury to two or more people; and
  • $15,000 for property damage to others
  • Important: You must also have uninsured/underinsured coverage in the same amounts as your bodily injury coverage

Nearly all car insurance policies have a provision that will adjust your coverage from the minimums required in your state to the minimum insurance or proof of financial responsibility in another U.S. state. So you do not need to get a new insurance policy for each state you are driving through.  However, if you buy a policy in a low limits state (e.g. Illinois or Idaho) but actually live in a high limits state (like Alaska), insurers will only write a policy where your car is principally garaged. So if your home is in Alaska, you should buy the minimum limits for Alaska.

Illinois’ required insurance limits are low, considering the cost of repair and damages likely to occur in an accident.  If you are in a serious collision and the damages you caused are greater than the coverage limits you purchased, you may be personally liable to pay for those damages that exceed your insurance coverage.

Illinois Auto Insurance Regulations

Illinois is a modified comparative fault state with a 50% rule.  This is a legal defense that means that a plaintiff can recover for an injury, reducing the amount that the plaintiff can recover based on the percentage of which the plaintiff is at fault if it is determined that his or her fault in causing the injury is less than 50%. If the plaintiff’s fault level reaches 50% or more, he or she cannot recover any damages resulting from the accident.
