Minimum Coverage

Illinois requires 25/50/20 liability plus mandatory uninsured motorist coverage. Learn state requirements, penalties, and why UM coverage cannot be waived.

Quick Answer: Illinois Minimum Auto Insurance

Illinois requires all drivers to carry liability insurance. The state-mandated minimums are:

Coverage TypeMinimum Required
Bodily Injury per Person$25,000
Bodily Injury per Accident$50,000
Property Damage$20,000
Uninsured Motorist BI$25,000/$50,000

This is commonly written as 25/50/20. Illinois is one of the states that also requires uninsured motorist coverage, making it more protective than many other states.


What Illinois Law Requires

Under the Illinois Vehicle Code (625 ILCS 5/7-601), all vehicle owners must:

  1. Maintain liability insurance at or above state minimums
  2. Carry uninsured motorist coverage (cannot be waived)
  3. Provide proof of insurance to law enforcement upon request
  4. Maintain continuous coverage on all registered vehicles

Understanding 25/50/20 Coverage

Bodily Injury Liability - $25,000/$50,000

Covers injuries you cause to others when at fault:

  • $25,000 maximum per injured person
  • $50,000 maximum per accident total
  • Pays medical bills, lost wages, pain and suffering
  • Does NOT cover your own injuries

Property Damage Liability - $20,000

Covers damage you cause to others' property:

  • Other vehicles you hit
  • Buildings, fences, guardrails
  • Personal property
  • Does NOT cover your own vehicle

Uninsured Motorist Bodily Injury - $25,000/$50,000

Protects you when hit by an uninsured driver:

  • Required in Illinois (cannot decline)
  • Covers your injuries if at-fault driver has no insurance
  • Same limits as your liability coverage minimum

Why Illinois Minimums May Not Be Enough

While Illinois requires decent coverage including UM, minimums still fall short in serious accidents:

Real-World Cost Comparison

ExpenseAverage CostIL Minimum Covers
Hospital stay (3 days)$30,000$25,000 per person
Spinal injury treatment$100,000+$25,000 per person
Average new vehicle$48,000$20,000 property
Multi-car pileup$150,000+$50,000 total BI

Personal Liability Exposure

If damages exceed your policy limits:

  1. Insurance pays to your coverage maximum
  2. You're personally responsible for the excess
  3. Injured parties can sue you directly
  4. Wages can be garnished in Illinois
  5. Liens can be placed on your home
  6. Judgments last 7 years (renewable to 27 years)

Example: A highway accident injures three people totaling $120,000 in medical bills and destroys a $45,000 vehicle.

  • Total damages: $165,000
  • Your 25/50/20 pays: $70,000 max
  • You owe: $95,000 out of pocket
