Illinois uses an at-fault insurance system, meaning the driver responsible for an accident is generally responsible for resulting damages. Drivers must carry the state's required liability insurance, while insurance costs vary based on factors such as driving history, location, vehicle, and coverage choices. Understanding Illinois' insurance requirements and selecting appropriate coverage can help provide better financial protection.
| Insurance System | At-Fault (Tort) |
| Minimum Liability | 25/50/20 ($25k Bodily Injury per Person / $50k Bodily Injury per Accident / $20k Property Damage) |
| Required Medical Coverage | No |
| Average Minimum Cost | $550/year |
| Average Full Coverage Cost | $2,100/year |
Drivers in high-cost insurance states often compare quotes aggressively to manage premium increases.
