What Is Liability Insurance Insurance?
Liability Insurance has two components: Bodily Injury Liability pays medical bills, lost wages, and legal costs when your teen injures someone in an at-fault accident, while Property Damage Liability covers repair costs for other vehicles, buildings, fences, or property your teen damages. If your 17-year-old rear-ends another car and injures the driver, Bodily Injury Liability pays their emergency room visit, physical therapy, and lost income up to your policy limits — commonly written as 100/300/100, meaning $100,000 per injured person, $300,000 total per accident, and $100,000 for property damage. This coverage does not repair your teen's own vehicle or pay for their injuries — those require Collision and Medical Payments coverage — but it protects your family's assets from lawsuits when your teen is at fault.
How Much Does Liability Insurance Insurance Cost?
- Teen's age and experience: 16-year-olds cost 40–60% more than 19-year-olds due to higher at-fault accident rates
- Liability limits you select: State-minimum coverage is cheapest but leaves you exposed; 100/300/100 limits cost 15–25% more but protect assets
- Your state's minimum requirements: Michigan and Florida have among the highest liability premiums due to lawsuit environments, while states like Ohio and Indiana run 30–40% lower
- Teen's driving record: A single at-fault accident increases liability premiums by 40–50% for 3–5 years; a speeding ticket adds 20–30%
- Vehicle type: Liability rates are marginally affected by vehicle — a teen in a 2015 Honda Civic costs about the same as a 2015 Toyota Camry, but sports cars like Mustangs or WRXs can add 10–20% to liability premiums due to riskier driving patterns
- Add-to-policy vs separate policy decision: Keeping your teen on your policy with multi-car and multi-policy discounts typically costs $1,800–$3,200 annually, while a separate teen-only policy often runs $4,000–$8,000 annually for the same liability limits
