Automobile liability insurance: what it covers and how much you need
Last reviewed September 3, 20264 min readBy the Goodsurance editorial team Reviewed by the Goodsurance editorial team
Automobile liability insurance pays for harm you cause to other people and their property when you are at fault in a crash. It does not pay for your own injuries or your own vehicle. Its purpose is to cover the financial exposure you create for others.
What automobile liability insurance covers
The coverage has two distinct parts. Bodily injury liability pays for the other party's medical expenses, lost wages, and pain and suffering when someone is injured or killed in a crash you caused. Property damage liability pays for damage to someone else's vehicle, fence, building, or any other property you hit. Both parts also cover your legal defense if the other party sues you, up to your policy's limits.
Because liability coverage protects other people rather than you personally, it is the mandatory layer that every state requires drivers to carry before they can legally operate a vehicle.
How bodily injury and property damage limits work
Liability limits appear in shorthand as three numbers separated by slashes, such as 30/60/15. Each number represents thousands of dollars in coverage:
- The first number is the maximum the insurer will pay for a single injured person.
- The second number is the maximum it will pay for all injuries combined in one accident.
- The third number is the maximum for all property damage in that accident.
California offers a concrete example of how states set and revise these floors. Effective January 1, 2025, California raised its minimum auto liability requirements to 30/60/15, meaning $30,000 per injured person, $60,000 per accident for all injuries combined, and $15,000 for property damage. According to the California Department of Insurance bulletin on SB 1107, this was the state's first increase in 56 years.
Once your policy limit is exhausted, any remaining judgment becomes your personal financial responsibility, payable from savings, wages, or assets.
State minimums and why they often fall short
Every state and the District of Columbia sets its own required minimums, and the numbers vary considerably. Regardless of where your state sets the floor, the minimum is the legal threshold, not a recommendation for how much protection you actually need.
Property-damage-only crashes made up 72% of all police-reported crashes in the United States in 2024, according to the National Highway Traffic Safety Administration. That share reflects how often collisions produce vehicle and infrastructure damage rather than injury, and even a moderate property-damage event can push past a state's minimum property damage limit when the other vehicle is new or when you strike more than one car or a fixed structure.
Medical costs after serious injuries can easily outpace standard per-person limits, and attorney fees compound the exposure quickly. If a judgment against you exceeds your coverage, the unpaid balance can be collected through wage garnishment or liens on real property, depending on state law.
72% of US crashes in 2024 caused only property damage. State minimums may not be enough to cover the full bill.
Choosing limits that protect your finances
The appropriate liability limit is shaped by what you stand to lose. Several factors are worth examining when you evaluate your options.
Assets and net worth. A court judgment can reach savings, investment accounts, and home equity. Higher limits reduce the gap between what your insurer pays and what a plaintiff could collect.
Income. Wages can be garnished in most states when a liability judgment goes unpaid. Drivers with consistent, verifiable income face more collection risk than those without attachable earnings.
Driving patterns. More time on the road raises exposure. High annual mileage or commuting through dense urban areas means more frequent interaction with other vehicles, cyclists, and pedestrians.
Umbrella coverage. Drivers who want protection beyond standard auto limits can layer a personal umbrella policy on top. Umbrella policies extend liability across auto, home, and other personal lines, though they typically require your underlying auto policy to carry a minimum limit before they engage.
A widely cited rule of thumb from financial planning circles is to carry liability limits at least equal to your net worth, though your specific situation may call for more. An independent insurance agent familiar with your state can walk through concrete scenarios.
Four questions to ask before picking your limits
What are your savings, investments, and home equity worth?
A court judgment can reach all of these. Higher limits reduce the amount a plaintiff could collect directly from you.
Do you have steady, verifiable income?
In most states, your wages can be taken to pay an unpaid judgment. Consistent income makes you a more reachable collection target.
How much do you drive and in what kinds of areas?
High annual mileage and dense urban driving put you in contact with more vehicles, cyclists, and pedestrians, raising your chance of a costly crash.
Would an umbrella policy give you better overall protection?
An umbrella policy extends your liability protection beyond your auto limit and also covers your home and other personal lines.
What liability insurance does not cover
Understanding the gaps matters as much as understanding what the policy does.
Your own medical costs. Bodily injury liability covers other people, not you. Your injuries after an at-fault crash are addressed by medical payments coverage, personal injury protection where state law makes it available, or your own health insurance.
Your own vehicle. Collision coverage, not liability, pays for repairs to your car after an at-fault accident.
Uninsured and underinsured drivers. If another driver hits you and carries no insurance or too little to cover your losses, uninsured and underinsured motorist coverage fills that gap. Liability coverage plays no role in that scenario.
Business and commercial use. Personal auto liability generally does not extend to situations where you use your vehicle for hire or delivery. A separate commercial or rideshare endorsement is required when your vehicle earns income.
Knowing these exclusions makes it possible to build a complete policy rather than discovering holes after a loss has already occurred.
What your liability policy pays for and what it skips
Covers
- Medical bills, lost wages, and pain and suffering for the other person
- Damage to another person's vehicle, fence, building, or other property
- Your legal defense costs if the other party sues you, up to your limit
Does not cover
- Your own medical costs after an at-fault crash
- Repairs to your own vehicle
- Losses when an uninsured or underinsured driver hits you
- Using your vehicle for hire, delivery, or other commercial purposes
Each gap requires a separate coverage type added to your policy.

What is collision coverage on a car insurance policy?
Collision coverage is the part of a car insurance policy that pays for damage to your own car after a crash.
It applies when your car hits another vehicle or an object, and when your car flips over. You choose a deductible, which is the share of the repair bill you pay before the insurer pays the rest. Collision is optional in most cases, but a lender or a leasing company often requires it while you still owe money on the car.
Do I need collision coverage if my car is paid off?
It depends.
Once the loan is paid off, no lender can require collision coverage, so the choice is yours. Ask yourself one question: if your car were wrecked tomorrow, could you replace it out of pocket without hurting your household? If the answer is no, collision still does real work. If the car is old and worth little, the claim payment may be small, since collision pays based on what the car is worth, not what a new one costs.
What does comprehensive car insurance cover?
Comprehensive covers damage to your car that does not come from a crash with another vehicle or an object.
Think of it as protection from events you cannot steer around. That includes theft, fire, hail, falling tree limbs, flooding, vandalism, and hitting an animal on the road. Broken glass usually falls here too. You pick a deductible, which is the part of the bill you pay before the insurer pays the rest. Comprehensive is optional unless a lender requires it.
Does comprehensive insurance cover a cracked windshield?
Yes.
Glass damage is usually handled under comprehensive, not collision, because a rock or road debris is not a crash. If a stone chips your windshield on the highway, that is a comprehensive claim. Your deductible still applies, which is the share of the bill you pay first. Some states require insurers to offer glass coverage with a lower deductible or none at all, and those rules vary by state. Fixing a small chip early usually costs less than a full replacement.
What happens if a deer runs into my car?
Hitting an animal is normally a comprehensive claim, not a collision claim, even though it feels like a crash.
Comprehensive covers the damage the animal caused to your car, minus your deductible. There is an odd twist: if you swerve to miss the deer and hit a tree or a ditch instead, that becomes a collision claim, because you struck an object. Report the incident to your insurer either way, and take photos of the damage before any repairs begin.
What is the difference between comprehensive and collision insurance?
Both pay for damage to your own car, but they split the world in two.
Collision handles crashes: hitting another vehicle, hitting an object like a pole or a guardrail, or rolling your car over. Comprehensive handles almost everything else: theft, fire, hail, flooding, vandalism, falling branches, and hitting an animal. Each one carries its own deductible, which is the part of the bill you pay before the insurer pays. You can buy them together or, in many cases, separately.
Is a stolen car covered by collision insurance?
No.
Theft falls under comprehensive coverage, not collision. Collision only pays when your car strikes another vehicle or an object, or when it rolls over. If your car is stolen and never found, comprehensive pays what the car was worth at the time it was taken, minus your deductible. If it is recovered with damage, comprehensive covers the repairs. File a police report first, since insurers ask for the report number when they open a theft claim.
Can I buy comprehensive without collision?
It depends on the insurer and on whether you owe money on the car.
Many insurers will sell comprehensive alone, since it covers theft, fire, and weather damage while the car sits parked. Buying collision alone is far less common. If a lender or a leasing company holds the title, it usually requires both, and that rule sits in your loan or lease contract, not in state law. Ask your insurer which pairings it allows before you drop a coverage.
What does an HO-6 condo insurance policy cover?
An HO-6 is the policy written for a condo owner.
It covers the parts of the home you own and the association does not: interior walls, flooring, cabinets, fixtures, and built in features, depending on how your association documents split things. It also covers your belongings, your liability if someone is hurt in your unit, and a place to stay if a covered loss makes your unit unlivable. Many policies add loss assessment coverage for your share of a building claim.
Do I need condo insurance if the building already has a master policy?
Yes.
In almost every case you still need your own policy. The master policy the association buys covers the building shell and shared areas like hallways, the roof, and the lobby. It does not cover what is inside your unit, your belongings, or your personal liability. Read your association bylaws to see where the master policy stops, since the dividing line differs from building to building. An HO-6 policy fills that space. Lenders usually require one before they will finance a condo.
What is loss assessment coverage on a condo policy?
When a covered loss hits the shared parts of a condo building and the master policy does not pay all of it, the association can bill each owner a share.
That bill is called an assessment. Loss assessment coverage is the piece of your HO-6 policy that helps pay your share. It applies to assessments tied to a covered loss, not to routine repairs or normal upkeep. Coverage amounts and rules vary by policy, so check your declarations page.
Does collision coverage pay if I hit a tree?
Yes.
Collision coverage pays to fix or replace your car when it crashes into an object or another vehicle. A tree counts as an object. It also applies if you hit a fence, a pole, or a guardrail, or if your car rolls over. You still pay your deductible first, which is the part of the repair bill you cover. Collision pays for your car damage even when the crash is your fault. It does not pay for the other driver's car.
