No-fault vs at-fault states: the map, and what changes after a crash

A no-fault state makes your own policy pay your injury costs first, whoever caused the crash, and bars most lawsuits for pain and suffering unless the injury clears a statutory threshold. Nine states work that way for everyone: Florida, Hawaii, Kansas, Massachusetts, Michigan, Minnesota, New York, North Dakota and Utah. Kentucky, New Jersey, Pennsylvania and the District of Columbia let the driver or the victim choose.

Published lists disagree on the count because the labels are rarely defined, and because the dollar “threshold” in several states is only one of two ways to qualify. This page defines each group by what the statute does and states the lawsuit threshold, with its section, for each no-fault and choice state. Sorted that way, the 50 states and DC come to nine no-fault, four choice no-fault (Kentucky, New Jersey, Pennsylvania and DC), 14 add-on and 24 tort.

Estimates and published averages, not a quote. Not insurance advice. State rules and insurer rules vary. Confirm requirements with your state insurance regulator or a licensed agent in your state.

Four groups, defined by what the statute does

Two features separate the systems: whether the law requires or offers first-party injury coverage on your own policy, and whether it limits lawsuits against the other driver.

• No-fault: a statute requires first-party injury benefits on the policy and limits lawsuits for noneconomic loss (pain and suffering) to injuries over a threshold, for every covered driver.
• Choice no-fault: the same two features, but the lawsuit limit binds only a person who accepts it. Kentucky, New Jersey and Pennsylvania decide at the policy; the District of Columbia decides after the crash.
• Add-on: a statute requires first-party injury coverage to be included in the policy, or requires the insurer to offer it, and does not limit lawsuits.
• Tort: neither feature. The injured person claims against the at-fault driver’s liability coverage for all losses, and first-party medical coverage is optional.

The Insurance Information Institute (III) uses the same four-way split on its no-fault background page. It names twelve no-fault states and Puerto Rico, lists Kentucky, New Jersey and Pennsylvania as the choice states, and defines add-on states without naming any. That last omission is why add-on lists diverge: commercial explainers that repeat the twelve no-fault states differ on the add-on set, one listing ten states and another eight plus the District of Columbia.

Nine states with no choice plus the three choice states make twelve, which is the III count. Add the District of Columbia, whose victims elect benefits after the crash, and the count is thirteen. A page saying nine, twelve or thirteen can be right about the same statutes; what differs is how it treated choice.

Each placement rests on statute text read for this page, except New Jersey, whose categories come from the state insurance department’s 2026 buyer’s guide. The 24 tort states were each checked for a medical payments or PIP requirement or mandatory offer, and none was found; the tort section gives the detail.

The map: 50 states and DC in four groups

Each tile carries a fill and a pattern, so the groups survive grayscale printing. Solid dark tiles with a square mark are no-fault; stripes are choice; dots are add-on; plain grey is tort.

The lawsuit threshold in every no-fault and choice state

The table gives each threshold’s construction and the section. “Verbal” means the statute lists qualifying injuries in words. “Dollar or list” means a medical-expense figure opens the claim, and so does any of a list of injuries; no state relies on a dollar figure alone.

These thresholds govern noneconomic loss. What happens to economic loss above the first-party benefits varies. New York’s statute bars recovery of “basic economic loss” between covered persons and leaves economic loss above it (5104(a)). North Dakota exempts a secured person from economic loss only “to the extent of all basic no-fault benefits” paid or payable (26.1-41-08(1)(b)). Michigan preserves damages for allowable expenses and work loss above the coverage limit (3135(3)(c)). The District of Columbia opens a claim when expenses exceed the PIP available (31-2405(b)(2)).

Benefit structures are on the state pages: New York no-fault, Michigan’s PIP choices and Florida’s rules.

Dollar figure, listed injury, or both

The III page labels Hawaii, Kansas, Kentucky, Massachusetts, Minnesota, North Dakota and Utah as monetary-threshold states. The statutes show the label is shorthand. All seven also list injuries that qualify at any dollar amount, so the money is a second door, not the only one. Five states have a verbal test only (Florida, Michigan, New Jersey, New York and Pennsylvania), the District of Columbia has a verbal test plus an economic route, and seven states have a dollar figure or a list.

Within the seven, the figures run from $1,000 to $5,000, and the wording around the figure differs in ways that matter at the margin. Kansas opens the claim at “$2,000 or more”. Massachusetts requires expenses “in excess of” $2,000. The same $2,000 of treatment therefore clears one threshold and not the other.

The second door matters more for modest injuries than the figure does. A person whose treatment costs $1,500 but who cannot perform substantially all daily activities for 75 days meets Minnesota’s “disability for 60 days or more”, and North Dakota’s list names “disability beyond sixty days”. The same facts fall short in the District of Columbia, whose duration prong is 180 continuous days, and New York’s list of qualifying injuries has no duration test at all. Minnesota defines disability as the inability to engage in substantially all usual and customary daily activities.

Does a broken bone open the door?

Six of the thirteen jurisdictions name a fracture, and they do it differently.

Choice states: when the election is made and what happens by default

In the four choice jurisdictions the lawsuit limit is not automatic. What differs is when the choice is made, what the default is and what the choice changes.

Kentucky’s structure has a feature no other state shares. The tort limits accepted by default come bundled with the right to basic reparation benefits, and a rejection removes the benefits along with the limits (304.39-060(8)). A person who rejects remains exposed to full lawsuits as a driver, and an injured person who has not rejected may claim full damages, including nonpecuniary damages, from a driver who has (304.39-060(7)). The rejection must be on file with the department before the accident it is meant to cover (304.39-060(4)), so it cannot be made afterward.

Pennsylvania’s default runs the other way from New Jersey’s. Silence on the Pennsylvania notice means full tort; silence on New Jersey’s coverage selection form means the limit. Pennsylvania’s limited tort lifts when the at-fault driver was convicted of, or accepted Accelerated Rehabilitative Disposition for, driving under the influence in that accident, is driving a vehicle registered in another state, intended the injury or lacks required financial responsibility, and for an occupant of a vehicle that is not a private passenger motor vehicle (1705(d)(1), (3)).

New Jersey’s buyer’s guide says the choice applies to the named insured, spouse, children and other relatives living in the household who are not covered under another auto policy. The District of Columbia is the outlier: PIP is optional insurance the insurer must offer (31-2404(a)(1)), the election is the victim’s, and it comes after the crash. Some lists file DC under add-on for that reason. We place it with the choice group because the lawsuit limit attaches only when the victim elects.

Add-on states: first-party coverage with no lawsuit limit

An add-on state requires first-party injury coverage, or requires the insurer to offer it, and leaves the right to sue untouched. Benefit amounts are on the medical payments versus PIP guide.

Texas is the add-on state readers most often ask about. Its statute makes PIP the default and puts the rejection in writing, but it contains no limit on suing and generally removes the insurer’s subrogation claim against the at-fault driver, so the benefit is first-party in practice. See Texas car insurance laws.

The 24 tort states: checked, and what they share

Alabama, Alaska, Arizona, California, Connecticut, Georgia, Idaho, Illinois, Indiana, Iowa, Louisiana, Mississippi, Missouri, Montana, Nebraska, New Mexico, North Carolina, Ohio, Oklahoma, South Carolina, Tennessee, Vermont, West Virginia and Wyoming make up the tort group. In these states an injured person claims against the at-fault driver’s liability insurer for medical bills, lost income and pain and suffering alike, and fault decides who pays.

The motor vehicle insurance statutes of each of the 24 were searched for a medical payments or PIP requirement or a mandatory offer, and none was found. The wording sometimes says so outright: South Carolina’s 38-77-144 states that no PIP coverage is mandated, and New Mexico’s 66-1-4.11 says a policy “may include” medical payments. The same check moved Maine, Nevada, Colorado and Rhode Island into the add-on group, which is one reason published add-on lists differ. The check covers statutes, not insurer regulations or policy forms.

In a tort state the first-party coverages that matter after a crash are the optional ones; the uninsured and underinsured motorist guide covers the gap left by a driver with little or no insurance.

What changes after a crash, group by group

The same crash is routed differently in each group. The table follows the injured person’s path, from the first medical bill to what a lawsuit can ask for.

The last row is the one readers most often get wrong. “No-fault” describes injury claims: the statutes read here limit actions for bodily injury, sickness or disease (Florida 627.737(1), Kentucky 304.39-060(2)(a), Massachusetts 6D), and none covers your bumper. Michigan preserves a claim for vehicle damage, up to $3,000 for accidents after July 1, 2020, to the extent insurance does not cover it (3135(3)(e)). Fault for the car is decided as in a tort state and drives the rating consequences in the at-fault accident guide.

Fault still matters inside the injury system. New York directs that a trier of fact determine the parties at fault before deciding whether an injury is serious (5104(a)). Michigan assesses damages on comparative fault and bars them for a party more than 50% at fault, and for a party driving without the required insurance (3135(2)(b), (c)). A no-fault state therefore removes fault from the first bill, not from the whole claim. How a shared-fault finding cuts or bars the rest is set by each state’s comparative negligence statute, quoted state by state in the comparative negligence guide for crashes where both drivers are at fault.

Rate benchmarks for two choice states are on the Pennsylvania and New Jersey rate pages.

A crash outside your home state’s system

A crash across a state line raises two questions: which policy pays your injury costs, and which state’s lawsuit rules apply. No statute read here supplies a general choice-of-law rule, so this section reports what each says.

On the benefits side, a policy usually carries its home-state coverage with it. New York requires the named insured and household members to receive first-party benefits for loss from an insured vehicle’s use outside the state, anywhere in the United States, its territories or possessions, or Canada (5103(a)(2)), and requires every owner’s liability policy to provide at least the minimum insurance the other state or province requires when the vehicle is used there (5103(e)). Delaware covers named insureds and household members injured as pedestrians or occupants of other registered vehicles in any state, its territories or Canada (2118(a)(2)d).

Visitors get the host state’s benefits in some systems and not in others. New York reaches the other way: an insurer doing business in the state, or under common control with one, that sells motor vehicle liability coverage in any state or Canadian province must write into each policy the New York financial security and first-party benefits for when the vehicle is operated in New York (Ins. Law 5107). Michigan has the opposite rule for its own accidents. An insurer authorized in Michigan is not required to provide PIP or property protection benefits for an accident in the state to an out-of-state resident it insures, unless that resident owns a vehicle registered and insured in Michigan (MCL 500.3163, amended 2019). The District of Columbia bars a nonresident owner from operating a vehicle there without the insurance the District requires (31-2403(b)(1)).

On the lawsuit side, seven statutes tie their limits to the place of the accident in their own words, as the table shows.

Pennsylvania’s limited tort has its own border rule: a limited-tort holder may recover as if full tort had been elected when the person at fault is operating a vehicle registered in another state (1705(d)(1)(ii)). Because Kentucky’s limit and Florida’s exemption attach to vehicles with the required security provided, who is protected depends on the security as well as on the location.

The state insurance department for either state can confirm what the policy owes, and a licensed attorney in the state where the crash happened can say which statute applies to a lawsuit. If the move is permanent rather than a trip, the moving states guide covers what changes with the policy, and the state minimum liability limits page covers the liability side. Other guides on injury claims are collected in the fault and injury section.
