Accident in another state: whose insurance laws apply to your claim

No single state's law governs an out-of-state crash. Your policy is a contract that normally follows the state where it was issued and your car is kept, the crash state sets the rules of the road, the reporting duties and often the rules for a lawsuit against the other driver, and your insurer's "out-of-state coverage" clause bridges the gap by lifting your liability limits to what the crash state requires. Which rules win on a given question depends on whether you are asking about your own benefits, a claim against another driver, or a duty to report.

This article separates those questions, shows where the answers differ for no-fault and at-fault drivers, and ends with a checklist for the first week.

Three questions, three different sources of law

Most confusion comes from treating "the law" as one thing. An out-of-state claim is really at least three separate problems.

A fourth question, which regulator can help if the insurer misbehaves, is covered near the end. The point of the table is that a rule from one row does not carry over to another. A crash state can have a strict reporting deadline while your policy is governed by home-state law, and the lawsuit can be governed by yet another state's damages rules.

What the out-of-state coverage clause does

Most personal auto policies contain a paragraph that deals with exactly this situation. An Insurance Journal Academy writer quoted the one in his own policy in a 2018 article: if an accident occurs in a state or province other than the one where the covered auto is principally garaged, the policy provides at least the minimum amounts and types of liability coverage required by law, with no duplicate payments for the same loss. He added that the clause is probably on nearly every policy written that year, and that its effect is to move the burden of matching each state's requirements from the driver to the insurer.

The mechanics are simple, and the worked example below uses made-up numbers.

Worked example. Say your home state requires only 25/50/10 liability limits and you carry exactly those. You drive into a state that requires 30/60/25. If you cause a crash there, the clause generally treats your policy as if its liability limits were 30/60/25 for that accident, so a $20,000 property damage claim is not capped at your $10,000. (The numbers are hypothetical, not any state's actual minimums; use the state car insurance requirements lookup tool for current figures.)

Four limits on the clause are worth knowing:

1. It lifts liability coverage, not everything. The clause quoted above speaks of "liability coverages required by law." By its words it does not add collision coverage, raise medical payments limits, or enlarge an umbrella policy. Wording differs by insurer and state, so check your own.
2. It follows the clause's exact words. In GEICO General Insurance Co. v. Lewis, decided by the Michigan Court of Appeals on September 9, 2026, a State Bar of Michigan summary says the court held that a GEICO policy issued in New York, covering a vehicle registered and garaged there, did not have to be raised to Michigan's default $250,000/$500,000 liability limits. The policy's clause applied only to coverage "required of out-of-state motorists by local law," and the court found Michigan law required no increase on those facts, including because the nonresident-vehicle rule in MCL 500.3102(1) applies only after a vehicle has been in Michigan for more than 30 days in a calendar year. That is a summary of one decision on specific facts, not a general rule, but it shows that the clause is read as written.
3. It does not stack limits. The "no duplicate payments" language prevents you from collecting the home-state and crash-state benefit for the same element of loss.
4. It is not a substitute for adequate limits. If your home-state minimum is lower than the crash state's, the clause only lifts you to the crash-state minimum. A serious injury claim can exceed either number. Whether to carry more than the minimum is a separate decision; see the coverage calculator.

Claims against the other driver: how a court picks the law

When you sue (or are sued by) another driver, the court first decides whose law applies. The rules for that decision are called choice-of-law rules, and they have changed a great deal in the last sixty years.

From "law of the crash site" to a multi-factor test

The old rule, in the Michigan Supreme Court's description, was lex loci delicti: the law of the place of the wrong governed every tort claim. In 1963, New York's highest court broke from that rule in *Babcock v. Jackson*. Three Rochester residents drove to Ontario for a weekend, the driver lost control, and the passenger was hurt. Ontario had a guest statute barring a passenger's suit against a driver; New York did not. The court refused to apply the Ontario statute, reasoning that its purpose was to prevent collusive claims against Ontario drivers and their insurers, and Ontario had no real interest in denying a remedy to a New York guest against a New York host.

That case opened what later courts call a choice-of-law revolution. In *Sutherland v. Kennington Truck Service* (Michigan, 1997), the court surveyed the field and described several modern approaches, including "interest analysis" and the Second Restatement's test of which state has the "most significant relationship" to the dispute. It observed that these approaches tend to produce forum law most of the time, roughly 55 to 77 percent of the time in the survey it cited, and that only a minority of states still follow the old crash-site rule. Michigan's own method is to apply Michigan law unless a "rational reason" calls for another state's law, which requires first finding that another state has a real interest in having its law applied.

The practical lesson is that you cannot assume the crash state's law governs, and you cannot assume your home state's does. The answer depends on where the suit is filed and on that state's method.

What can differ from state to state

These are the kinds of rules that vary and that a choice-of-law fight is usually about:

• How your own fault counts. Pure and modified comparative negligence reduce a recovery; in a handful of jurisdictions contributory negligence can bar it entirely. See how fault is determined in a car accident.
• Whether pain and suffering is available. Many no-fault states allow non-economic damages only above a threshold. Massachusetts, for example, allows pain-and-suffering damages in a motor vehicle case only if reasonable medical expenses exceed $2,000 or the injury falls in listed categories such as a fracture, per M.G.L. c. 231, section 6D. That statute is written for vehicles operated "within this commonwealth."
• Caps and special damages rules. Some states cap non-economic damages in certain cases or handle medical bills differently. See Billed vs paid medical bills: collateral source rule and LOPs.
• Time limits. Sutherland was itself a limitations case: the Ohio and Ontario periods were two years, Michigan's was three, and the plaintiffs filed after two years and 22 days. The Michigan court applied Michigan's period. Because the choice can decide whether a suit is timely at all, do not rely on the shortest or the longest period you have heard about. See statutes of limitations for car accident claims and ask an attorney early.

A licensed attorney licensed where the suit would be filed is the right person for these specifics. This article only maps the terrain.

No-fault and at-fault states: what travels with you

The sharpest differences appear when a driver from a no-fault state crashes in an at-fault state or the reverse. The reason is structural: in a no-fault system your own insurer pays certain benefits regardless of fault (personal injury protection) in exchange for limits on suing; at-fault systems do neither. See no-fault vs at-fault states for the basics.

Does PIP follow you out of state?

Often yes, but the statutes and policy forms differ, so compare three examples.

Michigan. MCL 500.3111 makes personal protection insurance benefits payable for accidental bodily injury in an accident outside Michigan, if it occurs within the United States, its territories and possessions, or Canada, and the injured person was a named insured, a spouse, a resident relative, or an occupant of a vehicle involved in the accident who was a Michigan resident (or whose vehicle's owner or registrant had PIP or approved security). So a Michigan policyholder hurt in another state generally keeps Michigan PIP.

The reverse case is addressed by MCL 500.3163: a Michigan-authorized insurer is not required to provide PIP or property protection benefits for an accident in Michigan involving an out-of-state resident insured under its liability policies, unless that resident owns a vehicle registered and insured in Michigan. And Michigan's tort limits are tied to the place of use: MCL 500.3135(3) abolishes tort liability "arising from the ownership, maintenance, or use within this state" of an insured vehicle, with exceptions that include economic damages for a nonresident who suffers death, serious impairment of body function, or permanent serious disfigurement. Read together, the Michigan statutes tie benefits to the policyholder and tort restrictions to the place of the crash.

New York. The mandatory PIP endorsement in 11 NYCRR 65-1.1 pays first-party benefits for accidents "within the United States of America, its territories or possessions, or Canada." Its definition of an eligible injured person includes the named insured and relatives, other people hurt using the insured vehicle in New York, and "any New York State resident" hurt using the insured vehicle outside New York while not occupying another vehicle. The endorsement also says a person cannot recover duplicate benefits for the same loss under no-fault coverage issued under another state's law, and it prorates when another state's mandatory first-party coverage overlaps. Where another state provides unlimited coverage for an element of loss, the New York carrier shares equally with that coverage until its own limit is used up.

Massachusetts. M.G.L. c. 90, section 34M grants PIP benefits in lieu of tort damages for accidents in the commonwealth, but states that "no such exemption from tort liability shall apply in the case of an accident occurring outside the commonwealth." If a person with a Massachusetts-registered vehicle's PIP sues in tort after an out-of-state crash, the PIP amounts otherwise due do not become payable until settlement or judgment and are reduced by the overlap. In other words, the tort exemption that normally accompanies Massachusetts PIP is not written to reach out-of-state crashes, so a tort claim stays available subject to whatever law the court applies, and PIP is adjusted for any overlap.

An at-fault resident in a no-fault state

If you live in an at-fault state and crash in a no-fault state, expect to deal with the crash state's thresholds if you sue, while your own medical payments coverage, health insurance and any PIP your home state requires respond under your policy. Whether the crash state's own no-fault carrier owes you anything depends on that state's definition of an eligible person, as the New York and Michigan examples show. Do not assume. Ask both your insurer and the other driver's insurer, in writing, which first-party benefits they say apply and why.

Reporting duties are set by the crash state

A different set of rules applies to reporting: the crash state's, and sometimes yours too. These vary widely, and thresholds change, so check the current rule.

• Police notice. Florida's section 316.065 requires a driver in a crash causing injury, death, or apparent damage of at least $2,000 to give immediate notice to local police, the sheriff, or the Florida Highway Patrol; the statute treats a violation as a noncriminal traffic infraction. An older figure of $500 circulates online, so read the current text.
• Motor vehicle agency report. The California DMV says on its accident reporting page that a driver must file an SR-1 within 10 days if anyone is injured or killed, however minor the injury, or if property damage is over $1,000, and that it is required in addition to any police or insurance report. The page does not say how this applies to drivers from other states, so ask the agency rather than assuming either way.
• Your policy. Your policy requires prompt notice of a loss, no matter where it occurred. Report to your own insurer even if you think the other driver is at fault, and read When the law requires you to report a crash to the DMV or police and do you need a police report after a car accident? for the general rules.
• Your home state. Some states' agencies want to hear about crashes involving their residents, even elsewhere. The state car insurance requirements lookup tool and your home DMV's site are the places to confirm.

A police report from the crash state also becomes the main evidence if the other driver disputes fault. If officers did not come, an exchange of names, insurance details and photos is the substitute; the after-accident checklist and information form tool provides a form.

Which regulator can help when two states are involved

If you have a problem with your own insurer's handling of an out-of-state claim, the insurance regulator is the right escalation point. The NAIC's state insurance department page tells consumers to find their state insurance department and file a complaint there; it lists contact information for every department but does not say which state to choose. The general principle is that a department supervises the insurers it licenses and the policies they issue in its state, so the state where your policy was issued is the natural first stop, and that department can coordinate with its counterpart if the other state's conduct is involved. A department also cannot decide a lawsuit between you and another driver or award tort damages. See how to file a complaint against a car insurance company for the complaint process.

A first-week plan after an out-of-state crash

1. Get safe, get help, call 911 if anyone is hurt, as in any crash.
2. Get the local police report number and the officer's agency. Ask how to obtain the report later.
3. Photograph the scene, the plates, the other driver's insurance card and license. Record the date, time, road and weather.
4. Notify your insurer the same day and tell the representative the crash occurred in another state. Ask which coverages apply and whether the out-of-state clause matters.
5. Check the crash state's reporting rules for a motor vehicle agency report with a deadline, such as a short form due within days.
6. Keep every medical record and bill, and tell each provider whether you have PIP, medical payments coverage or health insurance, because the order of payment depends on it.
7. Ask about a lawsuit's deadline before you leave the state if you were injured; the time limit may be shorter than you expect. Consult an attorney licensed in the state where you would file.
8. Do not sign a release or accept a quick settlement before you know the full extent of the injury.

Common questions

If I crash in a state with higher minimum limits, do my limits go up?

Usually your liability limits are raised to the crash state's required minimums for that accident, through the out-of-state clause, but only if your policy contains one and only for the types of coverage the clause names. Your declarations page shows your limits. If your policy has no clause, the question is a matter for the policy language and the law, and an attorney or your insurer should explain it.

Can I use my home state's no-fault benefits after a crash in an at-fault state?

Frequently, yes. Michigan's MCL 500.3111 and New York's mandatory PIP endorsement both provide benefits for accidents outside the state within the United States and, in some cases, Canada. The details, including who qualifies and how overlapping benefits are handled, differ, so read your own policy or ask your insurer to cite the provision in writing. For the New York and Michigan systems in depth, see New York no-fault: claim forms, IME cutoffs and arbitration and Michigan PIP: the fee schedule, attendant care limits and the MCCA.

Does the other driver's insurance follow the crash state's law?

The other driver's liability coverage is governed by that driver's policy, which usually includes the same kind of out-of-state clause (see crashes with out-of-state drivers and foreign visitors for crashes with visiting drivers, and Driving into Canada or Mexico: does your US policy cover a crash? if the crash was across a border). Their limits may be raised to your crash state's minimums, but not necessarily above their own policy's limits if those are already higher. Whether an at-fault or no-fault rule applies to your claim against them is the choice-of-law question described above.

Which state's court should I use?

That is a legal strategy question. Where a suit can be filed depends on personal jurisdiction over the defendant, and the court's choice-of-law approach affects the rules applied. Speak with a licensed attorney before filing anywhere, and before the limitation period runs out in any state that might apply.

Key takeaways

• Your own policy usually follows the state where it was issued and the car is garaged; the crash state controls reporting and the rules of the road; a court's choice-of-law method decides which state's tort rules apply to a lawsuit.
• The out-of-state coverage clause lifts your liability limits to the crash state's required minimums but is read according to its own words, and it generally does not add other coverages.
• No-fault benefits often travel with the policyholder, but statutes in Michigan, New York and Massachusetts show that eligibility, offsets and tort limits all differ.
• Reporting rules, thresholds and deadlines are set state by state and change; confirm the current rule with the crash state's agency.
• If two states are involved, start with the insurance department in the state where your policy was issued, and get a licensed attorney's advice on lawsuit deadlines and venue.
