No-fault vs at-fault states
How no-fault and at-fault systems differ, which states use each, the lawsuit thresholds in no-fault states, and what it means for your claim.
In an at-fault state, the driver who caused the crash pays for the other people's injuries through their liability insurance, and anyone hurt can sue them. In a no-fault state, your own personal injury protection (PIP) pays your medical bills and lost wages first, whoever caused the crash. You can sue the other driver for pain and suffering only if your injury crosses a legal threshold. No-fault applies to injuries only. Damage to cars is handled on a fault basis everywhere, with Michigan's special rules the main exception.
Who uses which system
Based on the 51 state guides on this site (50 states plus D.C.), checked against each state's statutes and regulators in 2026:
| System | States |
|---|---|
| No-fault (PIP required, lawsuits limited) | Florida, Hawaii, Kansas, Massachusetts, Michigan, Minnesota, New York, North Dakota, Utah |
| Choice no-fault (you or the policyholder can opt out of the lawsuit limits) | Kentucky, New Jersey, Pennsylvania |
| Add-on (PIP included or required, but no limit on suing) | Arkansas, Delaware, Maryland, Oregon, Texas |
| At-fault (traditional tort) | The other 33 states and D.C. |
Some at-fault states have twists. D.C. makes insurers offer optional PIP. If you buy it, you have 60 days after a crash to choose PIP benefits, which limits your right to sue, or a liability claim. Washington requires insurers to offer PIP, which you can reject in writing. Colorado and Wisconsin include medical payments coverage unless you reject it. The choice no-fault states are explained in Choice no-fault: New Jersey, Pennsylvania and Kentucky.
How a claim works in each
At-fault
- You claim against the at-fault driver's liability insurance (a third-party claim) for medical bills, lost wages, pain and suffering and car damage.
- If fault is disputed, payment waits until it is settled.
- If your share of fault is high enough, your state's negligence rule can reduce or bar recovery; see comparative vs contributory negligence.
- Meanwhile, your health insurance, medical payments coverage or your own collision coverage can pay first and seek repayment later.
No-fault
- You claim PIP from your own insurer for medical bills, a share of lost income and certain other costs, up to the PIP limit, with no fault investigation.
- If your injury meets the state's threshold, you can also sue the at-fault driver for pain and suffering and for losses PIP did not cover.
- Car damage is still a fault claim. The at-fault driver's property damage liability pays, or your collision coverage pays and your insurer recovers from them.
No-fault thresholds and PIP minimums
The lawsuit limit is either a monetary threshold (medical costs above a dollar amount) or a verbal threshold (a serious injury described in words), or both.
| State | Minimum PIP | When you can sue for pain and suffering |
|---|---|---|
| Florida | $10,000 (pays 80% of medical bills, 60% of lost income) | Permanent injury, significant scarring or death |
| Hawaii | $10,000 | After $5,000 in PIP benefits, or death, permanent loss of use, serious disfigurement |
| Kansas | $4,500 medical plus other benefits | Medical treatment of $2,000, or serious injuries such as fractures or permanent injury |
| Massachusetts | $8,000 | Medical bills over $2,000, or serious injuries including a fracture |
| Michigan | Mandatory, with a choice of medical limit since July 2, 2020 | Death, serious impairment of body function, permanent serious disfigurement |
| Minnesota | $40,000 ($20,000 medical, $20,000 non-medical) | Over $4,000 in medical expenses, 60 days of disability, permanent injury or disfigurement, death |
| New York | $50,000 | "Serious injury" as defined in the Insurance Law |
| North Dakota | $30,000 | Serious injury, including medical bills over $2,500 |
| Utah | $3,000 | Medical bills over $3,000, a broken bone, permanent disability or disfigurement, dismemberment, death |
Thresholds and benefits change; New York, for example, tightened its serious-injury definition in its 2026-27 budget. Check the state guide for current details, and see michigan's no-fault reform explained for Michigan's choice of PIP levels.
A worked example
Say you are rear-ended and run up $6,000 in medical bills and $2,000 in lost wages, with a soft-tissue injury that heals in two months.
- In an at-fault state such as Georgia, you claim all of it, plus pain and suffering, from the other driver's liability insurer, up to their limits. You may wait while fault and the amount are negotiated.
- In Florida, your PIP pays 80% of reasonable medical bills and 60% of lost income up to $10,000 in total, starting promptly. Because the injury is not permanent, you generally cannot sue for pain and suffering.
- In Minnesota, PIP pays the medical bills, and because they exceed $4,000 you can also pursue a pain-and-suffering claim against the at-fault driver.
Pros and cons
| No-fault | At-fault | |
|---|---|---|
| Speed of injury payments | Fast, from your own insurer | Can wait on fault and settlement |
| Pain-and-suffering claims | Limited to serious injuries | Available for any injury caused by someone else |
| What you must buy | PIP, often with significant limits | Liability; injury coverage for yourself is optional in many states |
| Fraud exposure | PIP has been a target of medical billing fraud | Fraud more often involves inflated injury claims against liability coverage |
| Cost | Three of the five most expensive jurisdictions in NAIC's 2023 data use no-fault or choice no-fault (Florida, New York, New Jersey) | Varies widely; Louisiana and D.C. are also in the top five |
No-fault was meant to cut lawsuits and get injured people paid quickly. Whether it lowers premiums depends heavily on the PIP limits, the thresholds and how well fraud is controlled.
What it means for your coverage
- In a no-fault state, PIP is required. Consider whether the minimum is enough, how it coordinates with your health insurance, and whether you need higher bodily injury liability limits for crashes that cross the threshold.
- In an at-fault state, your own injuries depend on the other driver's insurance. Uninsured and underinsured motorist coverage and medical payments coverage fill that gap.
- Wherever you live, PIP and MedPay pay your own bills; liability pays for others. See Personal injury protection (PIP) explained.
The state car insurance requirements lookup shows what your state requires.
Key takeaways
- Nine states use no-fault (FL, HI, KS, MA, MI, MN, NY, ND, UT), three use choice no-fault (KY, NJ, PA), and five are add-on states (AR, DE, MD, OR, TX).
- In no-fault states, your own PIP pays your injury costs first, and you can sue for pain and suffering only past a monetary or verbal threshold.
- No-fault covers injuries, not car damage. Vehicle damage is still paid by the at-fault driver's insurer or your own collision coverage.
- In at-fault states, uninsured motorist and medical payments coverage protect you when the other driver's insurance falls short.
- Thresholds and PIP minimums differ widely and change, so check your state's guide.
