What Is Liability Insurance Insurance?
How Much Does Liability Insurance Insurance Cost?
- Number and type of license points — a speeding ticket adds 15% to 30%, an at-fault accident adds 40% to 60%, and a DUI can double or triple your liability premium.
- Your liability limits — increasing from 25/50/25 to 100/300/100 typically adds $15 to $40/mo, a cost-effective upgrade if you have assets to protect.
- Your ZIP code and state — Michigan, Louisiana, and Florida have the highest liability costs due to lawsuit trends and medical costs, while Idaho, Maine, and Vermont are typically lowest.
- Your age and driving tenure — young drivers under 25 pay significantly more, but that penalty compounds with points; a 22-year-old with a speeding ticket may pay double what a 45-year-old with the same ticket pays.
- Credit-based insurance score in states that allow it — poor credit combined with points can push you into non-standard carriers with rates 50% to 150% higher than standard market.
- Annual mileage and vehicle use — higher mileage increases your liability exposure and premium, especially if you commute in heavy traffic where rear-end accidents are common.
