What no-fault insurance is
No-fault insurance is not a type of policy you buy on its own. It is the name for a state system that decides who pays for injuries after a car crash. In most states — the at-fault or tort states — the driver who caused the crash, or rather that driver's insurer, pays for the other driver's injuries. The injured driver has to show the other driver was at fault, and the claim runs through the at-fault driver's liability cover. In a no-fault state that first step is different: each driver's own insurer pays that driver's own injury costs, through personal injury protection, without anyone having to prove fault first. The word no-fault describes the payment route, not the absence of blame. Fault can still be decided later, for the parts of the claim the system does not cover, and a driver who caused a crash can still face a lawsuit if the injuries are serious enough.
The reason states adopted the system was speed. Proving fault takes time — police reports, witness statements, adjusters arguing over who did what — and medical bills do not wait for that argument to finish. No-fault was designed to get injury costs paid quickly, by removing the fault question from the first payment. The trade-off is written into the system itself: in exchange for prompt payment from your own insurer, your right to sue the other driver for pain and suffering is restricted. You can only step outside the no-fault system and sue if your injury meets a threshold the state defines, and the thresholds are the part of the system most people misunderstand, so they get their own section below.
It is worth saying plainly what no-fault does not do, because the name invites the wrong reading. It does not mean nobody is at fault, and it does not mean fault is never decided. It does not mean your insurer pays for everything: PIP has limits, and once those limits are reached the position changes. It does not cover damage to your car — that is handled under fault rules in every state, including no-fault states, through property damage liability and your own collision cover. And it does not remove the need for liability cover: every no-fault state still requires drivers to carry liability insurance, because liability is what pays when you injure someone else badly enough to clear the threshold, or damage their property.
The twelve no-fault states
The Insurance Information Institute lists twelve states plus Puerto Rico as having no-fault auto insurance laws: Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania and Utah. Puerto Rico also has a no-fault law. Three of the twelve — Kentucky, New Jersey and Pennsylvania — are choice no-fault states, which means drivers there can choose whether to stay inside the no-fault system with its limited right to sue, or to keep a broader right to sue, usually by selecting a tort option on the policy. In Pennsylvania the choice is between limited tort and full tort; in New Jersey it is the limitation-on-lawsuit option; in Kentucky drivers may reject the no-fault limitation. The choice changes what you can claim after a crash, so in a choice state the election on the policy is a decision worth understanding before a crash, not after one.
Washington, DC sits outside the list with its own system. The III notes that DC is neither a true no-fault nor an add-on state: it lets drivers choose between no-fault benefits and the fault-based system. Two states that once had no-fault laws no longer do — Connecticut repealed its no-fault law in 1993 and Colorado's expired in 2003 — and Michigan substantially restructured its system in 2020, including changes to the medical benefit choices drivers make. No state has added or repealed a no-fault system since 2020, and Florida's periodic repeal efforts had not been enacted as of 2025. State lists like this one describe the landscape; your state's department of insurance is the source of record, and the minimums and thresholds change over time.
The other states — the large majority — use the at-fault system. That includes Georgia, which this site covers in its own guide: Georgia is not a no-fault state, it is an at-fault state, with one limited exception in the form of optional medical payments cover, known as MedPay. The Georgia guide sets that out in full. Minnesota is the no-fault state in this site's new state programme, and its page explains how the system works there, including the state's required PIP. If you move between states, the system changes with you: a driver who moves from an at-fault state to a no-fault state needs PIP, and a driver moving the other way may find PIP is no longer required but still available.
PIP: what personal injury protection pays for
Personal injury protection is the cover that makes no-fault work. It is first-party cover, which means it pays you and your passengers, rather than paying someone else for harm you caused. In a no-fault state it is required by law, and the minimum amount is set by the state. The minimums differ widely from state to state, which is why no single figure is quoted as the PIP minimum here: Florida requires $10,000, New York requires $50,000, Minnesota requires $40,000 and New Jersey requires $15,000, and the other no-fault states set their own figures in between and below those. Whatever the minimum in your state, it is a floor, not a recommendation — a serious injury can use up a $10,000 PIP limit in a single emergency-room visit, and what happens then depends on your health cover and on whether the injury clears the threshold to sue.
What PIP pays for is broader than a hospital bill. In general terms it covers medical expenses for injuries from the crash, and in most no-fault states it also covers some lost wages if the injury keeps you from work, and some other costs such as essential services — the help you need at home while you recover — and, in the worst case, funeral expenses. The exact list is set by state law and by the policy, so two states' PIP covers are not the same thing with different limits; they are different benefits. Some states coordinate PIP with health insurance, so the order in which the two pay matters, and some let drivers choose a deductible on PIP or choose whether PIP is primary. These are choices on the policy, and they change what you pay out of pocket after a crash.
PIP also has relatives that are easy to confuse with it. Medical payments cover, or MedPay, pays medical expenses after a crash regardless of fault, but it is usually a smaller, simpler benefit than PIP — it generally covers medical bills only, not lost wages — and in most states it is optional rather than required. In a few states PIP-style benefits are required even though the state is not a no-fault state: Delaware, Arkansas, Maryland and Oregon require some form of PIP or first-party medical benefit as add-on cover. Oregon requires $15,000 of PIP. The distinction matters when you compare quotes across state lines: a quote that looks cheaper because it has no PIP may simply be a quote from a state that does not require it.
The threshold: when you can still sue
The threshold is the gate between the no-fault system and a lawsuit. In a no-fault state you cannot sue the at-fault driver for pain and suffering just because you were hurt; your injury has to meet the threshold your state sets. There are two kinds of threshold. A verbal threshold is defined in words: death, significant disfigurement, permanent injury, loss of a bodily function, and similar categories. A monetary threshold is defined by a dollar amount of medical expenses: your medical bills have to exceed a figure the state sets before you can sue. The III lists Florida, Michigan, New Jersey, New York and Pennsylvania as verbal-threshold states, and Hawaii, Kansas, Kentucky, Massachusetts, Minnesota, North Dakota and Utah as monetary-threshold states. Which kind your state uses changes the evidence that matters after a crash — under a verbal threshold, the medical description of the injury decides; under a monetary threshold, the size of the bills decides, which makes the cost of treatment part of the legal question.
In the three choice no-fault states the threshold is something you can elect away from, at a price. A driver in Pennsylvania who chooses full tort keeps the right to sue for pain and suffering without meeting a threshold, and pays more for the privilege; a driver who chooses limited tort pays less and accepts the threshold. In New Jersey the equivalent choice is whether to take the limitation-on-lawsuit option. In Kentucky drivers may reject the no-fault limitation. The saving from accepting the threshold is real, and so is the right you give up, and the choice is difficult to revisit after a crash — it is made when the policy is bought, and it binds the claim that follows. If you live in a choice state, read the election on your declarations page and make sure it says what you think it says.
Two cautions belong here. First, thresholds have been interpreted broadly by courts in some states over time, which has shifted where the line sits in practice — a verbal threshold that reads narrowly in the statute may have case law behind it that reads it more widely, and the reverse. Second, the threshold limits lawsuits for pain and suffering; it does not limit claims for the economic losses PIP does not cover, and it does not limit a claim where the injury is severe. None of this is legal advice: if your injury may clear the threshold, the question belongs to a lawyer in your state, not to a guide.
How a claim works in a no-fault state
The claim starts with your own insurer, not the other driver's. After a crash in a no-fault state you notify your own company and open a PIP claim for your injuries, and the company pays the medical bills and other PIP benefits up to the limit, usually after any PIP deductible you chose. You do not wait for a fault decision before treatment is paid for, and that is the point of the system. At the same time, the damage to the cars is handled separately, under fault rules: the at-fault driver's property damage liability pays for the other car, and your collision cover pays for yours, minus your deductible, if you carry it. The two tracks run side by side, and confusing them is the most common mistake after a crash in a no-fault state — people expect the injury claim and the car claim to move together, and they do not.
Deadlines matter more than most drivers expect. No-fault states set short windows for notifying the insurer and for submitting medical bills, and a bill submitted late can be denied even if the treatment was covered. The windows are set by state law and by the policy, and they are measured in days, not months, in some states. Keep every bill, every receipt and every record of time off work, and send them in promptly rather than collecting them for later. If the other driver's insurer contacts you about the injury claim, remember that your PIP claim is with your own insurer; the other driver's insurer is concerned with the fault-based parts of the claim, chiefly the property damage and any claim that clears the threshold.
If your injuries are serious, the claim can move outside the no-fault system. Once the PIP limit is reached, or once it is clear the injury meets the threshold, a claim against the at-fault driver becomes possible, and at that point the fault question — who caused the crash — becomes central again, along with the at-fault driver's liability limits. This is also where underinsured motorist cover earns its place: if the at-fault driver's liability limits are lower than your losses, your own underinsured motorist cover can make up some of the difference, where you carry it. The guides to uninsured motorist cover and to collision and liability on this site explain those two covers in full. Outside no-fault states the claim works differently, and the general route is in car insurance claims.
What no-fault does not cover
No-fault does not cover damage to cars, and it never did. If another driver hits your car in a no-fault state, the repair is paid under fault rules — by the at-fault driver's property damage liability, or by your collision cover if you carry it, or by you if neither applies. A driver who buys only the state minimum in a no-fault state and skips collision cover has no cover for their own car at all, and no-fault changes nothing about that. The same applies to the other driver's car: your PIP does not pay for it, your property damage liability does. Anyone who reads no-fault as meaning the insurers sort everything out between themselves will be unpleasantly surprised at the repair shop.
No-fault does not cover everything about an injury either. PIP has a limit, and the limit is often modest against the cost of a serious crash. It does not pay for pain and suffering — that is exactly what the threshold gates. It does not pay for injuries that are not from the crash, and it does not pay for treatment the policy or the state does not recognise. And it does not cover the passengers of the other car in the way people sometimes assume: each driver's PIP covers that driver's own household, and the other driver's passengers claim on their own driver's PIP or on the at-fault driver's liability, depending on the state. The details vary, and the policy wording decides them.
No-fault also does not make insurance cheaper on its own. Whether no-fault states cost more than at-fault states is a question with a genuinely mixed answer: on the NAIC's state-by-state figures the most expensive states for auto insurance include no-fault Florida, and the least expensive include no-fault North Dakota, and most of the gap between states comes from a small number of expensive ones. Fraud, medical costs, lawsuit rules and the PIP minimum all push the price in different directions in different states. No national figure is quoted here because no single national figure describes a system that is really twelve different systems with one name.
No-fault, state by state, on this site
This site covers no-fault in three places, and each one answers a different question. The Florida auto insurance guide explains how Florida's system works in practice, because in Florida personal injury protection is central and the fault and required-cover rules shape every quote. The Georgia guide explains the opposite case: Georgia is not a no-fault state, it is an at-fault state, and the guide sets out what that means for a Georgia driver, including the limited role of optional MedPay. The Minnesota page in the site's state programme explains a third case, a no-fault state with a $40,000 PIP requirement and uninsured and underinsured motorist cover alongside it. Read the page for your own state before you rely on the general description in this guide, because the general description is a map and the state page is the road.
Two other pages on this site belong next to this one. The guide to the states that do not require insurance explains the two exceptions to the national rule — New Hampshire, which does not require liability insurance at all, and the position in Virginia — and it is a useful check on the assumption that every state requires the same thing. The cheapest car insurance by state page compares profiles by state, and it shows how the minimum liability rules differ from state to state, including in the no-fault states. Both pages are linked below, and both are worth reading before you compare a quote from a no-fault state with a quote from an at-fault state, because the two quotes may not be buying the same cover. New Hampshire is the exception to the whole map: it requires no insurance at all, as states that don't require insurance explains.
Worked example
Consider two ILLUSTRATIVE drivers with the same crash. The first drives in Florida, a no-fault state with a $10,000 PIP requirement. After the crash she notifies her own insurer, opens a PIP claim, and her medical bills are paid from her PIP up to its limit, without waiting for a fault decision. Her car is repaired under fault rules, through the at-fault driver's property damage liability or her own collision cover. If her injury is a sprain that heals in a few weeks, she cannot sue for pain and suffering: a sprain does not meet Florida's verbal threshold, which requires a significant and permanent injury, scarring or disfigurement, or death. The second driver has the same crash in Georgia, an at-fault state. His medical bills are claimed against the at-fault driver's bodily injury liability, which means fault has to be established first, and there is no PIP paying in the meantime unless he bought optional MedPay. He can sue for pain and suffering without clearing a threshold, because Georgia has no threshold to clear. The two drivers had the same crash and the same injuries, and their claims took different routes, on different clocks, with different limits on what they could recover.
The example's value is the contrast, not the figures in it: the PIP limits named are the state minimums, and a real driver's PIP limit may be higher if they bought more. What the example shows is that no-fault trades one thing for another — prompt payment for a limited right to sue — and that the trade is worth a different amount to different drivers. A driver with good health cover and a high tolerance for process may value the right to sue more; a driver who needs bills paid quickly may value prompt PIP payment more. Neither preference is right in general; the system in your state is fixed either way, and the choice you actually have is the PIP limit you buy above the minimum, the deductible you accept, and, in a choice state, the tort option you elect.
