Auto Insurance Terms

Bodily Injury Liability

Bodily Injury Liability is the part of your auto insurance that pays for injuries you cause to other people in an accident. It covers medical bills, lost wages, pain and suffering, and legal defense costs if you're sued.

Core Takeaways

  • Bodily Injury (BI) Liability covers medical expenses and legal costs for injuries you cause to others in an accident.
  • BI liability is required in almost every state as part of minimum auto insurance requirements.
  • Limits are typically expressed as “per person/per accident” (e.g., $25,000/$50,000).
  • Carrying only minimum BI limits can leave you financially vulnerable in a serious accident.

What is Bodily Injury Liability?

In plain English: If you accidentally hit someone and they get hurt, BI liability pays for their medical treatment and any legal claims against you—up to your coverage limits.

How BI Liability Limits Work

BI liability limits are shown as two numbers, like $25,000/$50,000:

  • First number: Maximum amount paid per person injured in an accident
  • Second number: Maximum amount paid for all injuries in a single accident
Coverage Limits Per Person Per Accident Typical Monthly Premium
Minimum (most states) $25,000 $50,000 $30-$50
Standard $50,000 $100,000 $35-$60
Recommended $100,000 $300,000 $40-$70
High Coverage $250,000 $500,000 $50-$90

What BI Liability Covers

Bodily Injury Liability covers a wide range of expenses for people you injure:

  • Medical bills (hospital stays, surgeries, physical therapy)
  • Lost wages and loss of earning capacity
  • Pain and suffering
  • Legal defense costs if you’re sued
  • Funeral expenses in fatal accidents

Important: I’ve used our auto insurance calculator with different BI limits, and it’s eye-opening how little extra premium you pay for significantly more protection. Going from $25,000/$50,000 to $100,000/$300,000 usually costs less than $20 a month, but it can save you from financial ruin.

What BI Liability Doesn’t Cover

BI liability does NOT cover:

  • Your own injuries (that’s what PIP or health insurance covers)
  • Damage to your own vehicle (that’s collision/comprehensive)
  • Damage to other people’s property (that’s property damage liability)
  • Intentional injuries you cause

How Much BI Liability Do You Need?

  • Minimum Coverage — Only meets legal requirements; risky for most drivers
  • Standard Coverage — $50k/$100k; adequate for basic protection
  • Recommended — $100k/$300k; balances cost and protection
  • High Net Worth — $250k/$500k+; protects assets from lawsuits

Frequently Asked Questions

Is bodily injury liability required?

Yes, BI liability is required in almost every state. Only New Hampshire and Virginia have different requirements. Even in those states, financial responsibility laws still apply.

What happens if I don’t have BI liability?

You could face fines, license suspension, and even jail time. If you cause an accident, you’ll be personally responsible for all damages, which could lead to wage garnishment or asset seizure.

Does BI liability cover passengers in my car?

It depends on the state. In some states, your BI liability covers your passengers; in others, you need PIP or medical payments coverage for your passengers.

Should I get higher BI limits than the minimum?

Absolutely. Medical costs can be astronomical, and lawsuits for serious injuries can easily exceed minimum limits. The extra cost for higher limits is usually very reasonable.
