Minimum Coverage Requirements in Illinois
Illinois mandates minimum liability coverage of 25/50/20: $25,000 bodily injury per person, $50,000 per accident, and $20,000 property damage. Drivers convicted of DUI, caught driving uninsured, or accumulating multiple serious violations typically must file SR-22 proof of financial responsibility with the Illinois Secretary of State for 3 years. Uninsured motorist coverage is also required at the same 25/50 limits, though many high-risk drivers benefit from higher limits to protect against rate spikes from a second incident.
How Much Does Car Insurance Cost in Illinois?
High-risk auto insurance in Illinois costs significantly more than standard coverage due to elevated claim risk from violations, DUIs, or lapses. Premiums vary widely by violation type, with DUI drivers paying 150–300% more than clean-record drivers, and SR-22 filers facing both the filing fee and sharply higher underlying premiums. Rates also depend on age, location, vehicle, and which non-standard carrier accepts you.
What Affects Your Rate
- Violation type: DUI increases premiums 150–300%, while speeding tickets or lapses may add 30–80%
- SR-22 filing requirement adds $15–$35 to initial cost but signals high-risk status to all carriers
- Location: Chicago-area drivers pay 20–40% more than downstate due to higher claim frequency and uninsured motorist rates
- Age and experience: drivers under 25 with violations may pay double the rates of older high-risk drivers
- Credit-based insurance score: Illinois allows credit as a rating factor, and poor credit combined with violations compounds premium increases
- Number of incidents: multiple violations or a DUI plus at-fault accident can push premiums above $500/mo even for minimum coverage
