- Twelve states use no-fault car insurance: Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania and Utah. The rest, including Texas, Georgia and Colorado, are at-fault (tort) states.
- In a no-fault state, your own personal injury protection pays your medical bills first, whoever caused the crash. In an at-fault state, the driver who caused it (through their liability insurance) pays.
- No-fault only covers injuries. Car damage is still decided by fault in every state.
- You can step outside no-fault and sue only when your injuries pass a tort threshold. In New York that means a 'serious injury' as defined in law. See New York no-fault insurance.
- About 1 in 3 US drivers were uninsured or underinsured in 2023 (IRC). In an at-fault state, that makes your own uninsured motorist coverage your safety net. See is uninsured motorist coverage required in Georgia.
Picture two crashes that are exactly alike. A driver runs a red light and T-bones you, and you walk away with a broken wrist and $9,000 in medical bills. In Houston you'd claim against the other driver's insurance and wait while fault gets sorted out. In Brooklyn you'd file with your own insurer within 30 days, and it would start paying your bills whoever was to blame. Same crash, very different process. That's the difference between at-fault and no-fault car insurance states, and it shapes what coverage you should buy, how fast you get paid and whether you can sue.
This hub explains both systems in plain English, lists every no-fault state, and links to state-by-state answers. If you're new to car insurance, start with our car insurance guide and car insurance basics, then come back here.
What Is a No-Fault State?
In a no-fault state, every driver must carry personal injury protection (PIP). After a crash, your own PIP pays your medical bills, and usually some lost wages, no matter who caused it. Your passengers generally claim on your PIP too, and pedestrians you hit may be covered under it. The trade-off is that your right to sue the other driver for pain and suffering is limited. You can only sue when your injuries pass the state's tort threshold. The idea is faster payment for everyday injuries and fewer lawsuits over minor ones.
What Is an At-Fault (Tort) State?
In an at-fault state, the person who caused the crash is financially responsible, and so is their bodily injury liability insurance. You claim against the at-fault driver's insurer, or sue them, for medical bills, lost wages, pain and suffering and car damage. There's no threshold, so you can sue for any injury. The catch is that payment waits until fault is established, and if you were partly to blame, your payout may be cut or wiped out under your state's comparative negligence rule. That's why at-fault states lean on optional coverages such as MedPay and PIP and uninsured motorist coverage to fill the gap.
The 12 No-Fault States (and Their PIP Minimums)
| No-Fault State | Minimum PIP | Tort Threshold to Sue | Notes |
|---|---|---|---|
| Florida | $10,000 | Verbal (permanent or significant injury) | PIP generally pays 80% of medical bills. Motorcycles aren't included. See Florida motorcycle insurance |
| Hawaii | $10,000 | $5,000 in medical costs | |
| Kansas | $9,000 | $2,000 in medical costs | |
| Kentucky | $10,000 | $1,000 in medical costs | Choice no-fault: you can reject tort limits |
| Massachusetts | $8,000 | $2,000 in medical costs | |
| Michigan | Tiered choice (opt-out possible with qualifying health cover) | Verbal | Reformed in 2019 to give drivers PIP choices |
| Minnesota | $40,000 | $4,000 in medical costs | |
| New Jersey | $15,000 | Verbal | Choice no-fault (limitation-on-lawsuit option) |
| New York | $50,000 | Verbal ('serious injury') | See New York no-fault insurance |
| North Dakota | $30,000 | $2,500 in medical costs | |
| Pennsylvania | $5,000 (medical benefits) | Verbal (limited tort option) | Choice no-fault: full tort vs limited tort |
| Utah | $3,000 | $3,000 in medical costs |
Figures are based on ValuePenguin's state-by-state no-fault summary and each state's insurance code. Thresholds and PIP options change, so confirm the current rules with your state insurance department. Choice no-fault states (Kentucky, New Jersey and Pennsylvania) let you keep full rights to sue in exchange for a higher premium.
This is the most common misunderstanding. No-fault only changes who pays for injuries first. Car damage is still decided by fault in every state: the at-fault driver's property damage liability pays for your car, or your own collision coverage does. Fault also still goes on the at-fault driver's record and can raise their premium. See how long an accident stays on your insurance.
No-Fault vs At-Fault: Side-by-Side
| Question | No-Fault State | At-Fault State |
|---|---|---|
| Who pays your injury bills first? | Your own PIP, regardless of fault | The at-fault driver's liability insurer, once fault is set (or your own MedPay, PIP or health insurance in the meantime) |
| Can you sue for pain and suffering? | Only if you pass the tort threshold | Yes, for any injury |
| Who pays for car damage? | The at-fault driver (property damage liability) or your collision coverage | Same |
| Required injury coverage | PIP (mandatory) | Bodily injury liability. PIP or MedPay optional or must be offered in some states |
| Speed of injury payment | Usually faster | Can take months if fault is disputed |
| Premium impact | Often higher on average (PIP plus fraud costs) | Varies. Uninsured drivers push costs up |
| Examples | New York, Florida, Michigan | Texas, Georgia, Colorado, California |
Comparative Fault: How Blame Gets Split in At-Fault States
Most crashes aren't 100/0. States split blame in one of three ways, and it decides whether you get paid at all. According to Bloomberg Law's state-by-state negligence chart:
- Modified comparative, 51% bar. You recover damages reduced by your share of fault, but nothing if you're 51% or more to blame. Texas uses this rule. See is Texas an at-fault state.
- Modified comparative, 50% bar. You recover nothing at 50% or more. Georgia and Colorado use versions of this rule. See is Georgia a no-fault state and is Colorado a no-fault state.
- Pure comparative. You recover something even if you're mostly at fault, reduced by your share. New York uses this rule for lawsuits that clear its no-fault threshold.
- Contributory negligence. A handful of places bar recovery if you're even 1% at fault.
In at-fault states, adjusters use recorded statements to assign percentages of blame. A casual 'I didn't see him' can cost you 20% of your claim. Read can I refuse a recorded statement to an insurance company before you call them back.
The Uninsured Driver Problem (Both Systems)
The Insurance Research Council estimates that 15.4% of US drivers were uninsured in 2023 and 33.4% were either uninsured or underinsured. In an at-fault state, if the driver who hit you has no insurance, there's no liability policy to claim against. Your own uninsured/underinsured motorist (UM/UIM) coverage steps in. Some states require it, and others require insurers to include it unless you reject it in writing. Georgia is a good example, covered in is uninsured motorist coverage required in Georgia and in our real-life Atlanta uninsured driver scenario. For the legal side, see can an insurance company sue an uninsured driver.
What Coverage Should You Buy in Each System?
- In a no-fault state: Buy more than the minimum PIP if you can. New York's $50,000 goes fast after surgery. Carry solid bodily injury limits anyway, because serious crashes still end up in court. Learn the claim steps in how to file a no-fault insurance claim in New York.
- In an at-fault state: Don't decline MedPay or PIP when your insurer offers it. It pays while fault is argued over. Compare the two in PIP vs MedPay. Colorado insurers must include $5,000 of MedPay unless you reject it in writing.
- Everywhere: Carry UM/UIM matching your liability limits, liability of at least 100/300/100 if you have assets to protect, and an umbrella policy once your net worth exceeds those limits. Check yourself with how to know if you are underinsured.
Model the liability, PIP or MedPay and UM limits that fit your state's system and your savings.
