How to Lower Your Rate in Illinois
- Bundle home and auto with the same insurer — average saving: 15–20%
- Raise your deductible from $500 to $1,000 — saves $200–400/year on average
- Ask about low-mileage discounts if you drive under 7,500 miles/year
- Take a defensive driving course — qualifies for 5–15% discount with most carriers
- Pay annually instead of monthly — eliminates installment fees ($50–120/year)
