No-fault insurance is an auto insurance system in which your own insurer pays your medical bills and certain related losses after a crash, regardless of who caused it. You get faster access to benefits without having to prove the other driver was at fault. In exchange, you give up most of your right to sue that driver for pain and suffering unless your injuries cross a threshold set by your state. About a dozen states run on this model, and the coverage that makes it work is called Personal Injury Protection, or PIP.
What PIP Actually Pays For
PIP is broader than a health insurance substitute. The core benefit is medical: hospital stays, surgery, prescriptions, rehabilitation, and diagnostic testing tied to the accident. But most no-fault states extend PIP into several other categories that people forget about until they need them.
Lost wages are one. If your injuries keep you from working, PIP replaces a portion of your income, typically 60% to 85% of what you were earning, with a state-imposed cap on the monthly amount or the total duration. New York pays up to 80% of monthly income, capped at $2,000 a month for up to three years. Michigan pays 85% of wages up to roughly $5,400 per week. For higher earners, the dollar cap matters more than the percentage.
Essential services coverage reimburses you for hiring help with tasks you normally handle yourself, such as housekeeping, yard work, or childcare, when your injuries prevent you from doing them. Funeral and burial expenses are also covered in most states, usually with a cap between $2,000 and $5,000.
Which States Use No-Fault Insurance
No-fault is not the national default. Most states run on a traditional tort system, where the at-fault driver’s insurer pays the injured party’s damages. As of 2026, the states that require PIP and restrict lawsuits are Delaware, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania, and Utah.
Three of those give drivers a choice. In Kentucky, New Jersey, and Pennsylvania, you can opt out of the no-fault system and keep your full right to sue under regular tort rules. Drivers who stay in the no-fault system usually pay lower premiums but accept the lawsuit restrictions that come with it.
Florida is a moving target. It had been a no-fault state since 1971, but a 2023 law eliminates its PIP requirement effective July 1, 2026, replacing it with mandatory bodily injury liability coverage of $25,000 per person and $50,000 per accident. Florida drivers should confirm what their policy actually contains during the transition.
How Much Coverage the Minimum Buys You
Each no-fault state sets its own floor for PIP. The range is wide, and the number directly controls how much protection you have after a serious crash:
- Utah: $3,000
- Kansas: $4,500 for medical expenses, with separate limits for wage loss and other benefits
- Pennsylvania: $5,000
- Massachusetts: $8,000
- Hawaii: $10,000
- Kentucky: $10,000
- Delaware: $15,000 per person / $30,000 per accident
- New Jersey: $15,000
- North Dakota: $30,000
- Minnesota: $40,000 ($20,000 medical / $20,000 non-medical)
- New York: $50,000
- Michigan: $50,000 up to unlimited, depending on the tier you select1State of Michigan. Choosing PIP Medical Coverage
A $3,000 or $5,000 minimum disappears after one emergency room visit. If you live in a low-floor state and don’t have strong health insurance, buying PIP above the minimum is often one of the cheaper upgrades on an auto policy.
When You Can Still Sue the At-Fault Driver
No-fault restricts your right to file a lawsuit but doesn’t eliminate it. Every no-fault state defines a threshold that, once crossed, lets you step outside the system and sue the at-fault driver for pain and suffering and other non-economic damages. The threshold is what shapes how the system feels in practice.
States use one of two types. A verbal threshold requires you to prove your injury fits a category defined by statute, such as a bone fracture, permanent loss of a body function, significant disfigurement, dismemberment, or death. Insurers regularly dispute whether an injury truly qualifies. A monetary threshold is simpler: your medical expenses must exceed a fixed dollar figure before you can sue. The number varies by state.
Verbal thresholds tend to be harder to clear because the fight is over definitions. Monetary thresholds are more predictable, though in some states the dollar figure is low enough that it barely functions as a barrier. In choice no-fault states like New Jersey, you pick which threshold applies to you when you buy the policy, trading lawsuit access for lower premiums.
Filing a Claim After an Accident
One of the practical advantages of no-fault is that you file with your own insurer. You don’t have to identify the at-fault driver, negotiate with a stranger’s insurance company, or wait for a police report to sort out blame. You call your carrier, report the accident, and submit the claim.
Deadlines
Timing is unforgiving. Most no-fault states require you to notify your insurer of the accident within 30 to 60 days. New York’s rule is among the strictest, requiring written notice within 30 days.2Department of Financial Services. FAQ: Consumer Questions About No-Fault Insurance Some states also impose a deadline for seeking initial medical treatment; if you wait weeks to see a doctor, the insurer can argue your injuries weren’t caused by the crash. Miss either deadline and benefits can be denied outright.
Documentation
Your insurer will want medical records that tie treatment to the accident, along with billing statements from providers. If you’re claiming lost wages, expect to hand over pay stubs or employer verification. Keep copies of everything. Gaps in documentation give adjusters reasons to delay or reduce payment.
Independent Medical Examinations
Your insurer has the right to send you to a doctor of its own choosing for an independent medical examination, known as an IME. If that doctor concludes your treatment is no longer medically necessary, your benefits can be cut off. Refusing to attend can trigger automatic suspension of benefits. The IME doctor’s opinion often outweighs your treating physician’s records inside the insurer’s file.
How PIP Works With Health Insurance and Medicare
PIP doesn’t operate alone. After a crash, you may have health insurance, Medicare, Medicaid, and uninsured motorist coverage all potentially in play. The order in which they pay matters.
For accident-related medical care, PIP generally pays first. Health insurance takes over once PIP is exhausted. That order can matter a lot if you have a high-deductible health plan, because PIP can cover costs that would otherwise come out of your own pocket before the deductible is met.
Medicare follows the same rule. No-fault insurance pays first, and Medicare pays second. Providers who know about your PIP claim are required to bill the auto insurer before billing Medicare.3Medicare.gov. How Medicare Works with Other Insurance
Uninsured and underinsured motorist coverage does something different. If the at-fault driver has no insurance or too little liability coverage, UM/UIM fills the gap for damages beyond what PIP pays. That matters most in no-fault states when your injuries cross the lawsuit threshold but the at-fault driver can’t pay what a court awards.
What No-Fault Does Not Cover
The no-fault rules apply to bodily injury, not to vehicle damage. If another driver wrecks your car, you still pursue their liability insurance for repair or replacement, or you file under your own collision coverage. PIP has nothing to do with fixing your car. Michigan is the exception; its law limits property damage claims between drivers and allows only a small “mini-tort” recovery of up to $3,000 for damage not covered by your own insurance.4Michigan Legislature. MCL Section 500.3135
PIP also carves out several situations entirely. Injuries you cause intentionally are excluded. So are injuries suffered while committing a felony or driving a vehicle you knew was stolen. Using your personal car for commercial work such as ride-sharing or delivery, without adding commercial coverage, can void PIP for accidents during those activities.
One exclusion trips up families more than any other: the resident relative rule. In several no-fault states, a household member who owns a vehicle that should be insured but isn’t cannot collect PIP under another family member’s policy. If your adult child lives with you, owns a car, and lets the insurance lapse, they may lose access to your PIP entirely if they’re hurt in a crash. Racing, off-road events, and driving outside the policy’s geographic area are also commonly excluded.
What No-Fault Costs
No-fault coverage tends to run more expensive than comparable coverage in tort states. The broader benefits inside PIP and the guaranteed payout regardless of fault both push premiums up. Studies comparing the two systems have found premiums roughly 19% higher in no-fault states, though the gap moves with market conditions and regulatory changes.
Inside a no-fault state, your PIP coverage level is the biggest lever you control. Michigan’s tiered system shows this plainly: choosing the $50,000 PIP option instead of unlimited triggers an average premium cut of 45% on PIP alone.1State of Michigan. Choosing PIP Medical Coverage Beyond PIP levels, the usual factors apply: driving record, vehicle, ZIP code, and credit history where state law allows it. Shopping across carriers each year remains the most effective way to manage the cost, since insurers weight those factors differently and the cheapest option changes over time.
