Liability-only car insurance is the most basic auto coverage required in most states. It covers injuries and property damage you cause to others in an accident, not your own vehicle or medical bills. You choose your coverage limits, but you’re personally on the hook for anything beyond those limits. It’s considerably cheaper than full coverage, averaging around $820 annually. Keep exploring to find out if it’s the right fit for you.
Key Takeaways
- Liability-only car insurance covers injuries and property damage you cause to others but does not cover your own vehicle or medical expenses.
- Most states legally require liability coverage, with minimums expressed as split limits like 25/50/25 for bodily injury and property damage.
- Liability-only averages $620 to $820 annually, significantly cheaper than full coverage, which averages around $2,697 per year.
- It suits drivers with low-value vehicles worth under $5,000, paid-off cars, or those with strong financial reserves.
- Driving record and credit history heavily influence premiums; accidents can raise rates over 40%, while DUIs place drivers in high-risk tiers.
What Is Liability-Only Car Insurance?
Liability-only car insurance is the most basic auto coverage you can carry, and in most states, it’s the legal minimum required to drive.
Liability-only car insurance is the bare minimum. In most states, it’s exactly what the law requires.
It’s designed to protect you financially when you’re at fault in an accident. Specifically, it covers injuries or property damage you cause to others, not damage to your own vehicle or your own medical bills.
Most liability-only policies include two core components: bodily injury liability and property damage liability. Bodily injury liability covers injuries you cause to other people, while property damage liability covers damage you cause to someone else’s vehicle or property.
Coverage applies up to your chosen policy limits. If costs exceed those limits, you’re personally responsible for the difference.
Because it offers less protection than full coverage, liability-only insurance typically comes with lower premiums.
It’s a common choice for drivers who want to meet legal requirements while keeping costs down. In Illinois, driving without insurance carries a minimum fine of $500 and can result in vehicle registration suspension.
What Liability-Only Car Insurance Actually Covers
Knowing what liability-only coverage actually pays for helps you understand what you’re getting and what you’re not.
Liability-only insurance splits into two parts: bodily injury liability and property damage liability.
Bodily injury liability covers medical bills, lost wages, and pain and suffering for other drivers, passengers, or pedestrians you injure in an at-fault crash. If someone sues you, it can also cover your legal defense costs.
Property damage liability covers repairs or replacement of another person’s vehicle or other property you damage, including fences, mailboxes, buildings, and similar items.
Both coverages apply only up to the limits you’ve selected. If damages exceed those limits, you’re personally responsible for the difference.
One critical point: liability-only coverage protects others, not you.
Your own vehicle repairs, your medical bills, and your own lost wages fall outside its scope entirely. That distinction matters when you’re deciding whether this coverage is enough. For damages to your own vehicle, you would need collision protection as a separate addition to your policy.
What Liability-Only Car Insurance Won’t Pay For
Understanding the gaps in liability-only coverage is just as important as knowing what it includes.
If you cause an accident, liability-only insurance won’t pay to repair your own vehicle. You’ll cover those costs out of pocket unless you carry collision coverage.
Your medical bills and your passengers’ injuries aren’t covered either. You’d need medical payments coverage or personal injury protection for those expenses.
Personal property inside your car, including phones, laptops, and similar items, isn’t protected.
Neither is a rental vehicle while yours is being repaired, unless you’ve added that option separately.
Intentional acts, racing, rideshare use, and business driving are typically excluded from standard personal auto policies.
Driving in Mexico or other excluded locations may void your coverage entirely.
Finally, if a claim exceeds your policy limits, you’re personally responsible for the remaining balance. That exposure can be significant depending on the severity of the accident. Experts generally recommend selecting coverage matching net worth to reduce the risk of paying damages out of pocket.
How Much Liability Insurance Does Your State Require?
Every state sets its own minimum liability requirements, so what you’re legally required to carry depends entirely on where you live. Most states express minimums as a three-number split like 25/50/25, representing bodily injury per person, bodily injury per accident, and property damage per accident.
Every state sets its own minimum liability requirements. What you’re legally required to carry depends entirely on where you live.
Requirements differ considerably by state. California requires just 15/30/5, while Alaska mandates 50/100/25. Texas requires 30/60/25, and Illinois sets minimums at 25/50/20.
Some states add unique rules. Florida requires personal injury protection and property damage liability instead of standard bodily injury coverage, and New Hampshire doesn’t require insurance at all, though you’ll still need to prove financial responsibility after a crash.
Keep in mind that these minimums are legal floors, not financial safety nets. If a claim exceeds your limits, you’re personally responsible for the difference.
Several states, including California and Virginia, recently raised their minimums in 2025. New Jersey is also scheduled to increase its minimum limits in 2026.
Liability-Only vs Full Coverage: Cost, Protection and Lender Rules
When you compare liability-only to full coverage, the cost difference is significant. Averages range from roughly $621 to $820 per year for minimum coverage versus $1,970 to $2,697 for full coverage.
The protection gap is just as wide, since liability-only pays only for damage and injuries you cause others, leaving your own vehicle and injuries uncovered.
If you’re financing or leasing your car, your lender will likely require full coverage as a contractual condition, regardless of what your state mandates by law. Reviewing Liberty Mutual car insurance is a practical starting point for drivers comparing full coverage and liability-only pricing across major carriers.
Coverage Gap Comparison
Choosing between liability-only and full coverage comes down to cost, protection scope, and sometimes your lender’s requirements. Liability-only averages $805 annually, while full coverage runs about $1,631, a difference of roughly $826 per year. That gap reflects a significant difference in what’s actually covered.
With liability-only, you’re protected if you injure someone or damage their property. But if your car is stolen, totaled, or damaged in a crash, you’re paying out of pocket.
Full coverage adds collision and comprehensive protection, covering your vehicle against crashes, theft, weather, and vandalism.
If you’re financing or leasing, your lender will typically require full coverage. If you own your car outright, liability-only is an option, but it shifts the financial risk of vehicle loss entirely to you.
Lender Requirements Explained
If you’re financing a car, your lender will require more than just liability insurance. Liability-only coverage protects other people’s property, not your vehicle, which serves as the lender’s collateral.
Until you pay off your loan, most lenders require:
- Collision coverage, which pays for crash-related damage to your vehicle
- Comprehensive coverage, which covers theft, fire, hail, vandalism, and weather damage
- Gap insurance, which covers the difference between your loan balance and your car’s actual cash value
Lenders often call this combined package “full coverage.”
If your coverage lapses, your lender can impose force-placed insurance, which typically costs more and offers less protection than a policy you’d choose yourself.
Cost Difference Breakdown
The price gap between liability-only and full coverage is substantial. On average, minimum coverage runs about $820 annually, while full coverage climbs to roughly $2,697, a difference of nearly $1,877 per year.
MoneyGeek puts the gap at $826 annually, while MarketWatch estimates liability-only is about 69% cheaper than full coverage.
That monthly difference ranges from approximately $69 to $141, depending on your source and driver profile. If you’re paying toward the higher end for full coverage, switching to liability-only could free up meaningful cash each month.
However, the savings come with a tradeoff. You won’t have collision or comprehensive protection, so any damage to your own vehicle becomes your financial responsibility.
The right choice depends on your car’s value and your savings cushion.
How Much Does Liability-Only Car Insurance Cost?
Some insurers charge considerably less than the national average. Here are three of the lowest reported monthly rates from major carriers:
- USAA, $41 per month (median annual rate: $349)
- Auto-Owners, $52 per month (approximately $490 per year)
- Erie, $53 per month
On the higher end, Farmers averages $1,260 per year, while Progressive sits at $616 annually.
Your location also plays a major role. Progressive reports $87.56 per month in low-cost states versus $165.02 per month in high-cost states for the same liability-only policy.
If you’re paying $200 per month for liability-only coverage, that’s considered high compared to national averages and worth shopping around to reduce. Checking Mercury Insurance is one option worth considering, as the company is frequently noted for competitive liability-only rates in several states.
What Affects Your Liability Insurance Premium?
Your driving record is one of the most direct factors shaping your liability premium. At-fault accidents, serious violations, and DUI citations can all push your rates markedly higher.
Insurers typically review the past three to five years of your driving history, so even older incidents may still affect what you pay today.
Your credit history can also influence your premium, as many insurers use credit-based insurance scores as a pricing factor alongside your record behind the wheel.
Driving Record Impact
When insurers calculate your liability-only premium, your driving record carries considerable weight. They typically review the past 3 to 5 years of your driving history, including violations, accidents, and claims.
Even liability-only coverage isn’t immune to record-based pricing increases.
Here’s how specific record issues can raise your costs:
- Speeding tickets can increase your rate by roughly 25%, depending on severity and insurer.
- At-fault accidents involving claims around $2,000 can push rates up by over 40%.
- DUI citations often move you into a high-risk tier, triggering substantially higher premiums for multiple policy periods.
Maintaining a clean record remains one of the most effective ways to keep your liability-only premiums as low as possible. Drivers with recent violations may also want to explore usage-based options — Root Car Insurance prices policies based on actual driving behavior, which can benefit low-risk drivers regardless of past record issues.
Credit Score Influence
Beyond your driving record, your credit score can also shape what you pay for liability-only coverage. Insurers in many states use a credit-based insurance score, distinct from a lender’s credit score, to estimate your likelihood of filing a claim, and it factors into your overall premium just as it would with broader coverage.
The financial difference is significant. Drivers with poor credit pay roughly $2,729 per year, while those with exceptional credit pay about $1,308, a gap of $1,421 or 109% more.
Even dropping one credit tier can raise your premium by around 17%.
You can reduce that impact over time by paying bills on time, lowering outstanding balances, and limiting new credit applications.
Note that some states restrict how insurers can use credit information.
When Does Liability-Only Coverage Make Sense?
Liability-only coverage makes the most sense when your vehicle’s market value is low enough that paying for collision and comprehensive coverage costs more than you’d ever realistically recover in a claim. Cars 10 or more years old or valued under $5,000 often hit this threshold.
Beyond vehicle value, three situations consistently favor this approach:
- You own the car outright. No lender requires full coverage, so you’re free to prioritize cost over physical-damage protection.
- You drive infrequently or seasonally. Less time on the road reduces your exposure to costly claims, making lighter coverage more justifiable.
- You have strong cash reserves. If you can absorb repair or replacement costs without financial strain, you’re practically self-insuring the vehicle.
The core tradeoff is accepting out-of-pocket risk on your own car. That’s a reasonable bet when the vehicle’s replacement cost wouldn’t create serious financial hardship.
How Much Liability Coverage Do You Actually Need?
State minimums are the floor, not the ceiling, and there’s a big difference between what’s legally required and what actually protects you.
California’s minimum is just 15/30/5, and even the more common 25/50/25 gets exhausted fast in a serious crash. Medical bills, lost wages, rehabilitation, and legal defense costs add up quickly.
A widely recommended target is 100/300/100, meaning $100,000 bodily injury per person, $300,000 per accident, and $100,000 property damage.
Consumer Reports, the Insurance Information Institute, and AAA all point to this level as a strong baseline that balances protection with cost.
Beyond that benchmark, your net worth should guide your decision. Liability coverage needs to protect what you could lose in a lawsuit, including cash, investments, and property minus debt.
If damages exceed your policy limits, you’re paying the difference out of pocket. Higher net worth means higher exposure, and your limits should reflect that.
Frequently Asked Questions
Can liability-only insurance cover accidents that happen in another state?
Yes, your liability-only insurance generally covers accidents in another U.S. state. Your coverage follows you across state lines, and your insurer typically applies a broadening clause to meet the other state’s minimum requirements.
Does liability-only insurance protect you when driving someone else’s car?
Your liability-only insurance doesn’t protect the borrowed car itself, but it can cover damages you cause to others. The owner’s policy typically acts as primary coverage, while yours may serve as secondary if their limits are exceeded.
Can you add liability-only coverage to a classic or antique vehicle?
You can add liability-only coverage to a classic or antique vehicle, but many specialty insurers like Hagerty won’t offer it standalone. Availability varies by insurer and state, so check with your provider directly.
Does liability insurance follow the driver or the specific vehicle?
Liability insurance typically follows your vehicle, not you as the driver. If you give someone permission to borrow your car, your policy’s liability coverage usually applies first if they cause an accident.
Can liability-only insurance be bundled with homeowners or renters insurance?
Yes, you can often bundle liability-only auto insurance with homeowners or renters insurance. If your insurer offers both policies, you’ll typically qualify for a multi-policy discount ranging from 5% to 30%.
Conclusion
Choosing liability-only car insurance comes down to your vehicle’s value, your financial situation, and your risk tolerance. If you’re driving an older car and can cover repair costs yourself, it’s a smart way to save money. But if you’d struggle to replace your vehicle after an accident, full coverage might be worth the extra cost. Review your policy regularly to make sure your coverage still matches your needs.
