Phantom passengers and paper accidents: how inflated claims work

A phantom passenger is a person who files an injury claim for a crash they were not in, usually after a genuine low-speed collision between two drivers. The crash is real; the extra occupants appear later, in a claims file, a treatment record or a lawyer's demand letter. If you are the at-fault driver, you cannot stop someone from filing, but you can fix the record early: how many people you saw in the other car, what they said, and what you photographed. That record is what lets your insurer's investigators test a padded claim instead of paying it.

Real crash, padded claim: how this differs from a staged accident

Insurance investigators draw a line between several kinds of crash fraud, and the vocabulary matters. The National Insurance Crime Bureau (NICB) describes a "paper accident" as a crash that never happened and exists only as a police report or an insurance claim. It describes a staged accident as one where drivers, occupants and even witnesses play assigned roles, and passengers get scripts.

Phantom passengers fit neither description exactly. The collision happened, two real drivers were involved, and a repair estimate is probably accurate. What is false is who was in the car. The insurance industry's term for inflating an otherwise legitimate claim is buildup. The Insurance Research Council (IRC), in its February 2015 release on 2012 claims, defined buildup as the inflation of otherwise legitimate claims and found it was the most common form of abuse: claims with the appearance of buildup accounted for 15 percent of dollars paid on bodily injury and personal injury protection claims that year (IRC).

Where buildup ends and fraud begins is a legal question that depends on the state and the facts. Adding a person who was not there is a more serious category than exaggerating a real sprain, because the entire injury is invented. Our companion article, claim padding vs fraud: where the legal line falls, covers the legal distinction. For crashes that were arranged in advance, see the guide to staged car accident scams.

How a minor crash turns into several injury claims

The pattern investigators describe has a few steps. Each step creates a record, which is why records are where cases are won.

1. A genuine fender bender. Low speed, modest damage, often no ambulance. Nobody at the scene mentions injuries beyond perhaps a sore neck, or the police report lists only the driver.
2. Recruitment. In the schemes investigators describe, someone connects the driver, and sometimes people who were never present, with a clinic or lawyer. NICB's scene indicators for law enforcement note that a person who refuses treatment on the scene may have been contacted later "by a runner, attorney or medical facility" and decided to file a claim (NICB scene indicators). Florida makes some of this conduct a crime: it is unlawful to solicit business from a person involved in a motor vehicle accident with intent to defraud, with a minimum two-year prison term on conviction, and the statute bars most direct solicitation of crash victims for 60 days after the accident (Fla. Stat. 817.234(8), 2025). Other states have their own solicitation laws; see cappers, runners and illegal accident-case solicitation.
3. First notice of loss. The other driver's insurer first hears about the crash through the first notice of loss, sometimes a call from the claimant's own insurer, sometimes a letter of representation from a law firm. A later-added occupant may first appear here.
4. Treatment. The "passengers" begin treatment, often at the same clinics. NICB's South Carolina fraud-trend release of December 8, 2023 says rings with complicit passengers may visit multiple clinics and receive many treatments for soft-tissue injuries that medical imaging cannot verify (NICB).
5. The demand. After treatment, a demand letter arrives for each claimant, with bills attached. Because injury settlements are generally negotiated from the medical bills, a longer course of treatment produces a larger demand.

No single step proves anything. Plenty of real passengers are hurt, delayed symptoms are genuine, and people hire lawyers for honest reasons. NICB itself says its indicators "only indicate" the potential of fraud and are not actual evidence.

How occupants get recorded, and where the record can be wrong

The first official record of who was in each car is usually the police crash report, and it relies on what the people at the scene say.

Crash report forms generally have a field for the number of occupants in each vehicle and a passenger section. The Massachusetts Crash Report Manual, for example, tells officers to enter the total number of injured and uninjured occupants including the driver, and notes that the field is for reporting and safety analysis. Its data-quality audit found that problems often came from more occupants being counted than listed in the passenger section (Mass Crash Report Manual). That is a reminder that the report is only as complete as the scene was. If there was no police response, which is common for a parking-lot or low-speed crash, there may be no neutral record at all, and the first occupant list is whatever each party tells their insurer.

Three consequences for you:

• If a police officer comes, ask that the number of occupants in each vehicle be recorded, and say what you actually saw: "I saw one person in the car" is information, "there was nobody else" is a conclusion you cannot know about the back seat.
• If no officer comes, your own photos and notes are the record.
• If the other driver says nobody is hurt, that statement is worth noting, but do not treat it as an agreement not to claim. People can develop symptoms later, and a real injury is a real claim.

First-party and third-party claims: where the exposure lands

Which insurer pays, and how, changes what padding looks like.

A first-party claim is one you make on your own policy. A third-party claim is one made against someone else's bodily injury liability coverage. Our guide on first-party vs third-party claims covers the basics.

The first-party route matters because of volume. New York's Department of Financial Services reported that its Insurance Frauds Bureau received 36,835 suspected no-fault auto fraud reports in 2025, about 93 percent of all healthcare fraud reports it received (NY DFS 2025 annual health insurance fraud report). Insurers in New York are required to report suspected fraud to the department under Section 405 of the state's Insurance Law, so these are reports, not findings. The same report says the bureau opened 73 healthcare fraud investigations in 2025, resulting in 40 arrests. That gap shows how many reports never reach prosecution: reporting is easy, and proving intent is not. For the New York system, see No-fault medical mill fraud: what New York's rules aim to stop.

The third-party route is where the at-fault driver's own money can be at risk, which is why that driver has the strongest reason to document the scene.

A worked example with invented numbers

Say you rear-end a car at a stop sign at about 10 miles per hour. Your bumper cover cracks and the other car has a dented rear panel. The other driver is standing next to the car, says she is fine and exchanges information. You see no one else in the car, and you take photos from where you stand. You have liability limits of $25,000 per person and $50,000 per accident for bodily injury.

Three weeks later, your insurer tells you it has received a letter from an attorney representing the other driver and three passengers. Each says they were in the car and each claims neck and back injuries. A demand follows for $15,000 per claimant, $60,000 in total.

Here is how the numbers stack up. Each claimed amount is below the $25,000 per-person limit, but the four together exceed the $50,000 per-accident limit. If all four claims were paid in full, the insurer would run out of limit and you could be personally exposed for the rest. If the three added claims are not genuine, that is exactly why the identity of the occupants matters. The extra people multiply the claim's size without any increase in the force of the crash.

Your insurer's questions would likely include: who was seen at the scene, whether your photos show anyone else, whether the police report lists additional occupants, whether the passengers are named in any record created near the time of the crash, and whether the treatment records share providers. That is the heart of the next section.

What adjusters and special investigators look for

Insurers send claims with fraud indicators to a special investigations unit. The indicators below come from NICB's published guidance for law enforcement, which is written for staged accidents but overlaps with padding cases. None is proof.

• Several passengers in the vehicle that was not at fault. NICB says organized groups use multiple passengers so they can file claims for several people at once.
• Identical or similar soft-tissue injuries among occupants. NICB says all occupants complaining of the same subjective injury is a key indicator, especially when there are no visible injuries.
• Late-added occupants. A passenger who appears for the first time in a lawyer's letter weeks after a crash with no mention in the scene records.
• Occupants who cannot give consistent details. NICB lists people who cannot say where they were going, or who do not know each other's names or relationships.
• Matching statements. Occupants who give the same facts in the same words.
• Injuries inconsistent with the crash. A low-speed collision that supposedly produced injuries to everyone in the car.
• A shared treatment pattern. Many claimants treated at the same clinic. The IRC study found claims with apparent fraud or buildup were more likely to involve chiropractic care, physical therapy, alternative medicine and pain clinics. That finding describes claim files in aggregate; it does not mean a person who sees a chiropractor after a crash is committing fraud.
• Open-ended treatment. NICB notes that soft-tissue complaints can be spread over a longer period than, say, a broken arm, which has an expected healing course.

Investigators then test the claim: recorded statements, medical records reviews, an independent medical exam where the policy allows one, a check of prior claims, and sometimes an examination under oath. Our articles on independent medical exams and injury bill audits and social media and surveillance in injury claim investigations describe those tools, and how insurers investigate fraud covers the general process.

What the at-fault driver should document

If you are in a crash you caused, the aim is a clear, factual record. A few steps:

1. Photograph everything, including the other vehicle from several angles, the interior if it is visible through windows, license plates and the scene. Look for child seats, cargo and the number of seat belts in use only if you can see them without intruding.
2. Write down what you saw as soon as possible: how many people, where they sat, who spoke, who got out, what was said about injuries. Date and sign it.
3. Use a dash camera if you have one. Save the clip before it records over. See dashcam footage and scene evidence: what to capture and keep.
4. Collect witness names and numbers, and the officer's name and report number if there was one.
5. Tell your insurer promptly and accurately. Report the crash, say how many occupants you saw, and attach the photos. Do not guess or speculate about injuries.
6. Keep your statements short and factual. Recorded statements are standard, but you should know what to expect; see recorded statements: when to give one and when to wait and what to say and what not to say at the scene of an accident.
7. Do not contact the claimants or their lawyer yourself. Refer any approach to your insurer, which has the duty to defend a covered claim (see sued after a crash: how your insurer's duty to defend works).
8. Do not accuse anyone of fraud. Your job is to give your insurer accurate facts. Its investigators decide what to do with them, and an accusation can create problems of its own.

The after-accident checklist and information form pulls the scene steps into one list. If a demand exceeds your limits, read excess letters and time-limit demands: what to do as the insured and consider asking an attorney to review it with you.

What happens to a claim an insurer doubts

An insurer that doubts a claim generally has three choices: pay it, negotiate it down, or contest it. A claim that is entirely invented can lead to a referral to the state fraud bureau. New York requires insurers to report suspected fraud, as noted above, and other states have similar laws; state insurance fraud bureaus: who investigates and how to reach them explains how those offices work. Reporting is also open to the public: NICB takes reports at 800-835-6422 ("800.TEL.NICB" on its site), and your state's insurance department has a fraud unit too.

Whatever the insurer decides, the defense of a bodily injury claim is handled by the insurer's lawyers, not by you, as long as the claim is covered. A disputed claim can go on for months and may end in a settlement without any finding about whether a passenger was in the car, because insurers often settle on cost grounds. That is frustrating, but it is the system working as designed: the question of whether someone committed a crime is for prosecutors.

Common questions

Can I be blamed for a phantom passenger's claim?

You are not responsible for someone else's false claim. But a claim against your liability coverage can use up your limits and, if it exceeds them, reach your own assets. That is why accurate early documentation matters.

What if the other driver really had a passenger I did not see?

That is possible, and many real passenger claims come from people who were in the back seat. A person who was truly in the car and hurt has a valid claim. Do not assume the worst. Give your insurer the facts as you saw them and let it verify who was there.

Does a police report listing only one person settle it?

No. A report that lists one occupant is strong evidence that no one else was visible to the officer, but people leave before the officer arrives, and some reports are never filed. Insurers weigh it with photos, statements and medical records.

Should I report a suspected phantom passenger myself?

You can tell your insurer's claims representative what you observed and ask for the claim to be reviewed by its special investigations unit. You can also report to NICB or your state's fraud bureau. Stick to facts, not accusations.

Key takeaways

• A phantom passenger claim attaches an invented injury to a genuine low-speed crash; the crash is real, the occupant list is not.
• Fraud and buildup appear in a meaningful share of injury claims: the IRC's 2015 study of 2012 data found apparent fraud or buildup in 21 percent of bodily injury claims paid, though that measures appearance as judged by file reviewers, not proven fraud.
• Indicators such as multiple passengers, identical soft-tissue complaints and a shared clinic are signals for investigators, not proof.
• As the at-fault driver, document the occupants you see, photograph the scene, save video, and report accurately and promptly; do not confront claimants.
• Claims stack against your per-accident limit, so a few added occupants can turn a small crash into exposure beyond your policy.
