What Is Bodily Injury Liability Coverage?
Bodily injury liability (BI) coverage is one of the most fundamental parts of your auto insurance policy — and one of the most misunderstood. Simply put, it pays for the injuries you cause to other people when you're at fault in a car accident. This includes their medical bills, lost wages, pain and suffering, and even legal fees if they sue you.
It's important to understand what BI does not cover: your own injuries. If you're hurt in an accident you caused, your own medical costs would fall under Personal Injury Protection (PIP) or Medical Payments coverage — not bodily injury liability.
What Bodily Injury Liability Pays For
When you're responsible for an accident, your BI coverage can pay for:
| Expense Type | Examples |
|---|---|
| Medical Expenses | ER visits, surgeries, hospitalization, rehab |
| Ongoing Care | Physical therapy, prescriptions, mobility equipment |
| Lost Income | Wages the injured person couldn't earn while recovering |
| Pain & Suffering | Non-economic damages awarded in a lawsuit |
| Funeral Costs | In the event of a fatality |
| Legal Defense | Attorney fees and court costs if you're sued |
Bodily Injury vs. Property Damage Liability
These two coverages are often bundled together and confused, but they protect against very different types of losses. Understanding the distinction helps you build a policy that truly protects you.
Together, these two coverage types form what's known as liability insurance — the foundation of nearly every auto policy. Learn more in our guide to liability car insurance coverage and costs.

Understanding Bodily Injury Liability Limits
How Split Limits Work
Bodily injury limits are expressed as two numbers separated by a slash — for example, 25/50 or 100/300. These numbers represent thousands of dollars and tell you exactly how much your insurer will pay in a covered accident.
- First number = Maximum payout per injured person
- Second number = Maximum payout per accident (all injured people combined)
So a 100/300 policy means your insurer will pay up to $100,000 for any one injured person, and no more than $300,000 total for everyone injured in a single accident — regardless of how many people were hurt.
Common Coverage Tiers at a Glance
| Coverage Limit | Per Person | Per Accident | Best For |
|---|---|---|---|
| 25/50 | $25,000 | $50,000 | Meets many state minimums |
| 50/100 | $50,000 | $100,000 | Moderate protection |
| 100/300 | $100,000 | $300,000 | Recommended by most experts |
| 250/500 | $250,000 | $500,000 | High-asset individuals |
State Minimum Requirements: 2025–2026 Updates
Multiple states have recently raised their mandatory minimums — in many cases for the first time in decades. Here's a summary of the most significant changes:
| State | Previous BI Limits | New BI Limits | Effective Date |
|---|---|---|---|
| California | 15/30 | 30/60 | January 1, 2025 |
| Utah | 25/65 | 30/65 | January 1, 2025 |

| New Jersey | 25/50 | 35/70 | January 1, 2026 |
| Hawaii | 20/40 | 40/80 | January 1, 2026 |
Even with these updates, many states still allow minimums as low as $25,000/$50,000. Check your state's specific requirements with our car insurance minimum requirements guide.

How Much Bodily Injury Liability Coverage Do You Need?
What Experts Recommend
Financial experts and insurance professionals broadly agree: 100/300 is the minimum you should seriously consider, and more if you have significant assets. The national average bodily injury liability claim reached approximately $28,278 in 2024, according to Insurance Information Institute data — and a serious multi-person accident can easily generate claims in the hundreds of thousands of dollars.
Here's how experts generally match recommended BI limits to your asset level:
| Net Worth / Assets | Recommended BI Limits |
|---|---|
| Under $50,000 | 50/100 at minimum |
| $50,000 – $500,000 | 100/300 (most common recommendation) |
| Over $500,000 | 250/500 + personal umbrella policy |
Upgrading from a state-minimum policy to 100/300 limits typically costs only $13–$25 more per month — a modest price compared to the financial exposure you're eliminating. Review our car insurance coverage recommendations to find the right level for your situation.
If your net worth is substantial, consider pairing 100/300 BI limits with a personal umbrella policy, which can add $1 million or more in additional liability protection — often for just $300–$600 per year in 2026. Our guide on choosing car insurance liability limits can help you decide exactly how much protection makes sense.
Factors That Affect Your Bodily Injury Premium
The cost of bodily injury liability coverage varies widely based on several personal and geographic factors. Liability-only car insurance averages $50–$75 per month nationally, but your actual rate depends on:
| Factor | Impact on Premium |
|---|---|
| Driving Record | A DUI can raise premiums by up to 83%; a speeding ticket by ~24% |
| At-Fault Accident History | Prior accidents raise rates by ~41% on average |
| Credit Score | Poor credit can increase premiums significantly |
| Age | Teen drivers can pay 2–3x more than adults over 25 |
| Location | Michigan averages ~$154/month for liability-only; South Dakota as low as ~$29/month |
| Coverage Limit Chosen | Higher limits cost more, but the jump from minimum to 100/300 is often modest |
To keep your premium manageable while increasing limits, compare quotes from multiple insurers. Use our guide on how much car insurance coverage you really need to benchmark what you should be paying.
When Your Limits Aren't Enough: Real-World Consequences
What Happens When Limits Are Exceeded
This is where insufficient coverage becomes a life-altering problem. When the damages you cause exceed your policy's limits, your insurer stops paying — and you become personally liable for the rest.
Here's what that can mean in practice:
- Lawsuits: The injured party can sue you directly for the amount your insurance didn't cover
- Wage Garnishment: Courts can order a portion of your paycheck be withheld to satisfy a judgment
- Asset Liens: A lien can be placed on your home or other property
- Bankruptcy: In extreme cases, drivers have been forced into bankruptcy

Real-World Scenarios
Scenario 1 — Multi-Car Accident: A driver with a 25/50 policy causes a pileup injuring three people, generating $500,000 in total damages. The insurer pays the $50,000 per-accident cap. The driver is personally sued for the remaining $450,000.
Scenario 2 — Pedestrian Strike: A driver with $50,000 BI per-person coverage hits a pedestrian who incurs $300,000 in medical costs and lost wages. Insurance pays $50,000. The driver is sued for $250,000 — and faces asset seizure.
Scenario 3 — Highway Crash: A driver with 100/300 coverage rear-ends a vehicle at highway speed. Two occupants sustain serious injuries totaling $180,000 combined. The 100/300 policy covers everything, and the driver faces no out-of-pocket liability.
Understanding property damage liability coverage and how it works alongside your BI limits is also an important part of building a complete, well-rounded auto insurance policy.
Frequently Asked Questions (FAQ)
Is bodily injury liability the same as personal injury protection?
No, they are two very different coverages. Bodily injury liability pays for injuries you cause to other people in an at-fault accident. Personal injury protection (PIP) pays for your own medical expenses and lost wages after an accident, regardless of who was at fault. In no-fault states, PIP is typically required. Learn more in our guide to how car insurance covers medical expenses.
What is a good bodily injury liability limit to carry?
Most insurance experts recommend at least 100/300, meaning $100,000 per person and $300,000 per accident. This level of coverage handles most serious accident scenarios without requiring you to pay out of pocket. If you own significant assets like a home or investments, consider going higher or adding an umbrella policy. See our full guide to choosing the right liability limits for your situation.
Does bodily injury liability cover passengers in my own car?
No. Bodily injury liability covers people in other vehicles or pedestrians that you injure. Your own passengers' medical expenses after an accident you caused would typically be covered under Medical Payments (MedPay) or PIP coverage. Learn about how car insurance covers medical expenses as a complement to your BI coverage.
Can someone sue me even if I have bodily injury coverage?
Yes. If the damages from an accident exceed your BI policy limits, the injured party can sue you personally for the difference. Your insurer will defend you up to your policy limits, but anything beyond that is your personal responsibility — and could result in wage garnishment or asset seizure. This is one of the most important reasons to carry adequate limits and consider reviewing your overall car insurance coverage needs.
How does bodily injury liability work in a no-fault state?
In no-fault states, each driver's own PIP coverage typically handles their medical expenses first, regardless of fault. However, bodily injury liability still applies when injuries are severe enough to meet the state's lawsuit threshold — for example, when medical costs exceed a set dollar amount or injuries meet a defined severity standard. Review the latest liability-only car insurance guidance to understand how your state's rules apply to your policy.
