What Is Liability Only Car Insurance?
Liability only car insurance is the most basic form of auto coverage available — and the minimum required by law in nearly every U.S. state. Unlike full coverage, it only pays for damage or injuries you cause to other people. Your own vehicle, your own injuries, and your own property are not protected.
A liability-only policy is made up of two core components:
| Coverage Type | What It Pays For |
|---|---|
| Bodily Injury Liability (BI) | Medical bills, lost wages, and legal fees for people you injure in an at-fault accident |
| Property Damage Liability (PD) | Repairs to other vehicles, fences, buildings, or property you damage |
Coverage limits are written in a three-number format such as 25/50/25, which means:
- $25,000 per injured person
- $50,000 total per accident
- $25,000 for property damage
Some states also require additional protections like Personal Injury Protection (PIP) or Uninsured Motorist Coverage (UM) as part of their minimum package — so your "liability-only" policy may include a few extras depending on where you live. You can learn more about how bodily injury liability works and what limits mean for you personally.

What Liability Insurance Does NOT Cover
This is where many drivers get caught off guard. Liability insurance only faces outward — toward the other party. Here's what it will not pay for:
If someone hits your car and flees the scene, or a hailstorm dents your hood, liability-only leaves you paying out of pocket. That's why understanding the difference between liability car insurance vs. full coverage is so critical before choosing your policy.

Average Liability-Only Insurance Costs by State
One of the biggest advantages of liability-only coverage is cost. Nationally, liability-only car insurance averages between $820 and $1,407 per year — compared to $2,297 or more annually for full coverage. That's a potential savings of $1,000+ per year, depending on your state and driving profile.
Here's a snapshot of what liability-only coverage costs in select states:
| State | Est. Annual Cost | Est. Monthly Cost |
|---|---|---|
| Hawaii | ~$600 | ~$50 |
| Idaho | ~$480 | ~$40 |
| Iowa | ~$500 | ~$42 |
| Arkansas | ~$614 | ~$51 |
| California | ~$774 | ~$65 |
| Arizona | ~$826 | ~$69 |
| Georgia | ~$888 | ~$74 |
| Nevada | ~$1,020 | ~$85 |
| Delaware | ~$1,128 | ~$94 |
| Florida | ~$1,248 | ~$104 |
Note: Costs vary based on your age, driving record, vehicle, ZIP code, and insurer. These figures represent average estimates for minimum liability coverage. Always compare quotes from multiple providers to find the cheapest liability only insurance for your situation.
State minimum requirements also shift over time. For example, California raised its minimums to 30/60/15 in January 2025, and New Jersey is phasing in 35/70/25 by 2026. Keeping up with car insurance minimum requirements by state ensures you're always compliant.
Who Should Consider Liability Only Insurance?
Liability-only isn't the right fit for everyone — but for certain drivers, it's a smart financial decision. Here's a breakdown of who benefits most:
The 10x Vehicle Value Rule
A widely used rule of thumb for deciding between liability-only and full coverage is the 10% rule:
If your annual full coverage premium exceeds 10% of your car's current market value, dropping to liability-only may make financial sense.
For example, if your car is worth $8,000 and you're paying $1,200/year for full coverage, that's 15% of the car's value — well above the 10% threshold. In this case, switching to liability-only could free up over $800 annually that you could put toward a future vehicle fund.
To apply this rule:
- Look up your car's current value on Kelley Blue Book or similar tools
- Get a full coverage premium quote
- Divide the premium by the car's value
- If the result is above 10% (0.10), liability-only is worth considering
Liability-only insurance for older cars is one of the most common and financially sound reasons to drop full coverage. Drivers of paid-off, lower-value vehicles can redirect that premium savings toward an emergency fund. For those who don't even own a vehicle, non-owner car insurance is a liability-only alternative worth exploring.
Recommended Coverage Limits Beyond State Minimums
Just because you've chosen liability-only doesn't mean you have to stick with the bare legal minimum. State minimums are often dangerously inadequate in real-world accidents, and the financial consequences of being underinsured can be severe.
The Risks of Minimum Coverage
- You're personally on the hook for any damages that exceed your limits. If your policy covers $25,000 in bodily injury and the injured party's bills reach $90,000, you owe the remaining $65,000.
- Your assets can be seized. Courts can garnish wages or place liens on property to satisfy a judgment against you.
- Medical costs have surged. State minimums set years ago don't reflect today's emergency room bills, surgeries, or long-term rehabilitation costs.
- Rising repair costs. Modern vehicles loaded with sensors, cameras, and technology cost significantly more to repair — making property damage minimums like $10,000–$15,000 inadequate in many accidents.
Recommended Liability Limits
| Level | Bodily Injury | Property Damage | Best For |
|---|---|---|---|
| State Minimum | 25/50 (varies) | $10K–$25K | Legal compliance only — not recommended |
| Mid-Range | 50/100 | $50K | Drivers with moderate assets |
| Recommended | 100/300 | $100K | Most drivers — strong protection |
| High/Umbrella | 250/500+ | $100K+ | High net worth individuals |
Most insurance professionals recommend a minimum of 100/300/100 as your liability limits. The cost difference between minimum coverage and 100/300/100 is often just a few dollars per month — but the protection gap is enormous. For a deeper look at property damage liability coverage and how to choose the right limit, it's worth reviewing your options carefully.
Frequently Asked Questions
What does liability only car insurance cover?
Liability only car insurance covers two things: bodily injury liability and property damage liability. Bodily injury pays for the medical bills, lost wages, and legal costs of people you injure in an at-fault accident. Property damage covers repairs to the other party's vehicle or any property you damage. It does not cover your own car, your own injuries, or any non-collision damage like theft or weather.
How much does liability only insurance cost on average?
Liability only car insurance costs vary widely by state, but national estimates range from roughly $820 to $1,407 per year. Low-cost states like Hawaii or Iowa may see annual premiums under $600, while higher-cost states like Florida or Delaware can reach over $1,000 annually. Your individual rate is also influenced by your age, driving history, credit score, and the insurer you choose.
When should I switch from full coverage to liability only?
The best time to switch is when your vehicle's value has dropped to the point where full coverage premiums no longer make financial sense. Use the 10% rule: if your annual full coverage premium exceeds 10% of your car's current value, liability-only may be the smarter choice. You should also have enough savings to cover a potential out-of-pocket repair or replacement before making the switch.
Is liability only insurance enough to drive legally?
Yes — as long as you meet your state's minimum coverage requirements. Nearly every state mandates some form of liability coverage, and a basic liability policy will satisfy those legal requirements. However, "legal" and "adequate" are not the same thing. State minimums are often far too low to fully cover a serious accident, and you remain personally responsible for any damages that exceed your policy limits.
Can I get liability only insurance on a financed car?
No. If your vehicle is financed or leased, your lender or lessor requires full coverage — including collision and comprehensive — as a condition of the loan. Dropping to liability-only on a financed vehicle violates your agreement and can lead to force-placed insurance, which is typically far more expensive and benefits the lender, not you. Once the vehicle is fully paid off, you have the freedom to reassess your coverage needs.
