No-fault insurance pays your own medical bills and lost wages after a car accident, regardless of who caused it

No-fault insurance is a system where your own insurance company pays your medical expenses and a portion of lost income after a car accident — even if the other driver was at fault. You do not have to prove the other person caused the crash to receive payment. Instead, you file a claim with your own insurer, which processes it faster than waiting for someone else's insurance company to accept responsibility.

This system exists in 12 states plus Puerto Rico. If you live in one of these places, your car insurance policy must include no-fault coverage by law. The states that require it are Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania, and Utah. If you live elsewhere, your state uses a fault-based system, where you pursue a claim against the other driver's insurance company after proving they caused the accident.

The trade-off is important: no-fault insurance gets you paid quickly, but it typically limits how much you can sue the other driver for pain and suffering. You can usually only sue if your injuries meet a certain threshold — either a specific dollar amount in medical bills or a serious injury definition that varies by state.

Key Takeaways

  • No-fault insurance pays your medical bills and part of your lost wages directly from your own policy, without proving who caused the accident.
  • Twelve states require no-fault coverage by law: Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Pennsylvania, and Utah.
  • You file a claim with your own insurance company, which typically processes it within weeks rather than months.
  • In exchange for faster payment, you usually cannot sue the other driver for pain and suffering unless your injuries are serious enough to meet your state's threshold.

How no-fault claims work step by step

After an accident, you report the crash to your own insurance company, not the other driver's insurer. You provide your policy number, details about the accident, and the names of anyone else involved. The insurer will ask for a police report number if one exists, photos of vehicle damage, and medical records if you sought treatment.

Your insurance company then pays your personal injury protection (PIP) benefits directly. PIP covers medical treatment, hospital bills, surgery, rehabilitation, and prescription medications related to the accident. It also reimburses a portion of wages you lost because you could not work — typically 60 to 85 percent of your lost income, depending on your state and policy.

You do not wait for the other driver's insurance to accept fault. Your own company processes the claim based on your policy terms, not on who caused the accident. This means you can start receiving payment within two to four weeks in most cases, rather than the months it can take in a fault-based system where insurers argue over liability.

What no-fault insurance covers and what it does not

No-fault coverage pays for reasonable and necessary medical treatment directly related to the accident. This includes emergency room visits, surgery, physical therapy, mental health counseling, and ongoing medical care. It also covers transportation to medical appointments, home care if you cannot manage daily tasks, and childcare or household help you need because of your injuries.

What it does not cover: vehicle damage, lost or damaged personal property in the car, rental car costs, or pain and suffering. Those expenses fall under other parts of your policy — collision coverage for vehicle damage, comprehensive coverage for theft or weather damage, and rental reimbursement for a temporary car. Pain and suffering claims require a separate lawsuit against the other driver, and only if your injuries meet your state's threshold.

Coverage limits vary by state and by your policy. Some states set a minimum amount your policy must provide; others let you choose. In Michigan, for example, the minimum is $250,000 in lifetime benefits, but you can purchase higher limits. In New York, the minimum is $50,000. Check your policy documents or call your insurer to see what limit you purchased.

The difference between no-fault and fault-based systems

In a fault-based system (used in most states), you must prove the other driver caused the accident before their insurance pays anything. You file a claim with their insurer, provide evidence of fault, and their company investigates. If they agree they are liable, they pay. If they disagree, you may need to hire a lawyer and file a lawsuit. The process often takes months or years.

In a no-fault system, you skip that argument. Your own insurance pays your medical bills and lost wages when ready, based on your policy, not on who was at fault. The other driver's insurance company does not get involved in your medical claim at all. This speed is the main advantage — you are not waiting for someone else's insurer to decide whether to pay you.

The disadvantage is the cap on pain and suffering lawsuits. In a fault-based state, you can sue for any amount of pain and suffering if you can prove fault. In a no-fault state, you can only sue if your injuries are serious — the definition depends on your state's law. Some states use a dollar threshold (your medical bills must exceed a certain amount), while others use a verbal threshold (your injury must be permanent, serious, or cause significant scarring).

When you can sue the other driver in a no-fault state

Even in a no-fault state, you can sue the other driver for pain and suffering if your injuries meet your state's legal threshold. The threshold varies significantly. In New York, you can sue only if you suffered a "serious injury" — defined as permanent loss of use of a body part, permanent disfigurement, fracture, or significant limitation of function lasting 90 days or more. In Florida, the threshold is a permanent injury, significant scarring, or loss of a body function.

Michigan uses a different approach: you can sue only if your medical bills exceed $5,000 or you suffered a serious impairment of body function. Other states have their own definitions. You need to know your state's specific rule because it determines whether a lawsuit is even possible in your case.

If you do meet the threshold and decide to sue, you would file a lawsuit against the other driver's insurance company. Your own no-fault insurer continues to pay your medical bills and lost wages while the lawsuit proceeds. Any settlement or judgment you receive for pain and suffering goes to you, though your insurer may have a right to recover some of what they paid for your medical care — a process called subrogation.

How to file a no-fault claim

Start by calling your insurance company's claims line. Have your policy number ready, along with the date, time, and location of the accident. Describe what happened and whether anyone was injured. The insurer will assign a claims adjuster and explain what documents you need to provide.

Gather and submit: a copy of the police report (if one was filed), photos of vehicle damage, medical records and bills from any treatment you received, pay stubs or a letter from your employer showing lost wages, and receipts for any other accident-related expenses. Your insurer will tell you how to submit these — usually through an online portal, email, or by mail.

Your adjuster will review everything and determine what is covered under your policy. They will then authorize payment to your medical providers directly, or reimburse you if you paid out of pocket. For lost wages, they typically pay you directly once you provide proof of income loss. The entire process usually takes two to six weeks, though complex cases with serious injuries may take longer.

What happens if you disagree with the insurer's decision

If your insurance company denies a claim or offers less than you believe you are owed, you have options. First, ask the adjuster to explain their decision in writing. Request a copy of the policy language they used to deny the claim, and review it carefully to see if you misunderstood your coverage.

If you still disagree, you can file a formal appeal with your insurance company. Most states require insurers to have an appeal process. You submit additional evidence or documentation that supports your claim, and a different reviewer examines it. This process is free and usually takes 30 to 60 days.

If the appeal is denied, you may be able to file a complaint with your state's insurance commissioner or department of insurance. You can also consult with an attorney who handles insurance disputes. Some states allow you to pursue arbitration or mediation before going to court, which is faster and less expensive than a lawsuit.

Frequently Asked Questions

Do I have to carry no-fault insurance if I live in a no-fault state?

Yes. No-fault insurance is mandatory in the 12 states that have it. Your policy must include personal injury protection (PIP) coverage. You cannot opt out. The minimum amount varies by state — check your state's requirements and your current policy to confirm you have the required coverage.

Can I use my no-fault insurance if I was at fault for the accident?

Yes. That is the entire point of no-fault insurance. Your own policy pays your medical bills and lost wages regardless of who caused the crash. The other driver's insurance company does not get to decide whether you deserve payment based on fault.

What if the other driver does not have insurance?

Your no-fault insurance still pays your medical bills and lost wages. You do not need the other driver's insurance information to file a claim with your own company. If you want to pursue a lawsuit for pain and suffering (and meet your state's threshold), you may need to use your own uninsured motorist coverage to recover damages.

Does no-fault insurance cover passengers in my car?

Yes. Passengers injured in your vehicle can file a no-fault claim with your insurance company. They do not need to be related to you or listed on your policy. Your PIP coverage extends to anyone in the vehicle at the time of the accident.

Can I choose a higher PIP limit than the state minimum?

Yes, in most no-fault states. You can purchase additional PIP coverage beyond the legal minimum. Higher limits cost more in premiums but provide greater protection if you suffer serious injuries. Contact your insurance agent to discuss what limit makes sense for your situation.
