Can your telematics data be used in a claim or a lawsuit?

Yes. Driving data collected for a discount can be used in a claim, and it can be pulled into a lawsuit. At least one major program, Progressive's Snapshot, says in its privacy statement that it uses the data for claims, including to validate the circumstances of a loss and to make liability and coverage determinations, and that it can share the data in litigation. Whether a given piece of data helps or hurts you depends on what it shows, not on who holds it.

Telematics data is evidence, not a verdict. It does not decide fault by itself, because fault is decided under state law by an adjuster, an arbitrator or a court. What it does is add a record of speed, braking and timing that did not exist in the days when every crash was one driver's word against another's.

What the data can show

Different tools record different things, and the differences matter in a dispute.

The first two rows come from Progressive's Snapshot privacy statement, which says the device records vehicle speed, time of day, plug-in and unplug times and the vehicle identification number, and may record G-force and GPS location, and that the app collects driving data (speed, GPS location, phone sensor data) plus phone information such as whether the screen is locked or the phone is in use. Other programs collect different sets. GEICO's DriveEasy page says it measures how hard you brake, how fast you take corners and how often you use your phone, and it includes a feature, Accident Aware, that sends a notification when a hard brake is detected.

For a crash, the useful facts are usually four: how fast you were going, whether and when you braked, whether the phone was in use, and where you were at what time. A trip log can also show the opposite of what a witness says, for better or worse.

Do insurers use it to decide fault or deny a claim?

They can use it, and the program terms say so. Three things are worth separating.

The insurer's stated uses. Progressive's statement lists claims as a purpose for device and app data, including detecting accidents, validating the circumstances of a loss, making liability and coverage determinations, and investigating fraud, and it lists subrogation and litigation among the claims uses. In 2021, Consumer Reports reviewed the telematics programs of the ten largest insurers and, in the Consumer Federation of America's summary, reported that nearly all of them say in their terms of service that they can analyze insurance claims. Not every program page says this, so read your own. GEICO's DriveEasy page, for example, describes crash notification and does not say whether the data is used in claims.

What the record can and cannot do. An adjuster applies the policy and the state's fault rules to the facts. In a comparative-negligence state, data showing you were speeding could raise your share of fault and reduce what you recover; in a contributory-negligence state, a small share of fault can bar recovery from the other driver. The Consumer Reports review flagged this specifically, warning that telematics could help insurers blame policyholders or delay, reduce or deny claims, especially in contributory negligence states, and said it was unclear how telematics data determines partial fault. The how fault is determined in a car accident guide covers the standards.

A denial still needs a policy reason. Telematics data cannot create a coverage exclusion that the policy does not contain. If a claim is denied or reduced, ask for the reason in writing and the specific policy provision it relies on. That is a reasonable request, and your state insurance department can tell you what an insurer must put in a denial letter where you live.

None of this means joining a program hurts your claim. Data that shows you braking before an impact, driving under the limit, or stopped when you were hit can be the best evidence you have.

How the data reaches a lawsuit

A lawsuit reaches data through discovery, the process in which each side can demand relevant evidence from the other and from third parties. The federal rules illustrate the principle; state courts have their own rules, which are often similar but not identical.

Under Federal Rule of Civil Procedure 26(b)(1), parties may obtain discovery of any nonprivileged matter relevant to a claim or defense and proportional to the needs of the case, and information need not be admissible to be discoverable. Rule 45 lets a party serve a subpoena on a nonparty, such as an insurer or app provider, to produce documents or electronically stored information. The nonparty can object, and the court must quash or modify a subpoena that imposes undue burden or requires privileged material.

What this means for telematics:

• Your own device and app. If you are a party, the other side can ask you for your phone data or app records. Deleting them after you reasonably expect a dispute can create separate problems, and a lawyer can explain the duty to preserve evidence in your state.
• The insurer's copy. The other side can subpoena your insurer for the data it holds. Progressive's statement says driving data can be shared with third parties as legally required, citing subpoenas and police investigations, and with litigation parties and other insurers in claims.
• Your own insurer's interests. If you are sued after a crash, your insurer typically defends you. Its data may help or hurt, and you are generally expected to cooperate with the defense.
• Limits. Discovery is not unlimited. Relevance, proportionality, privacy and burden objections apply, and courts can set conditions. A request for a year of location history for a single-car crash is easier to challenge than a request for the trip on the day of the crash.

Whether a particular record is admitted at trial is a separate question decided by the judge under the rules of evidence. For specifics in your case, a licensed attorney is the person to ask.

Telematics versus the event data recorder

People often confuse the two, but the legal position is different.

An event data recorder is a device built into most newer vehicles that saves a short record when a crash-level event happens. Federal rules in 49 CFR Part 563 list the required data elements, including change in speed, vehicle speed, accelerator and service-brake status for a short window before the event, and safety belt status. The data tables contain no location or GPS entries. The window before the event depends on the vehicle's build date under the rule's phase-in schedule, so check the rule or the owner's manual for your car.

Federal law also sets who can read an EDR. The Driver Privacy Act of 2015, reproduced as a note to 49 U.S.C. 30101, says data retained by an event data recorder is the property of the owner or, for a leased vehicle, the lessee. It bars access by anyone else unless a court or other judicial or administrative authority authorizes retrieval, an owner or lessee consents in writing, electronically or by recorded audio (including by a subscription that describes how data will be retrieved and used), the data is retrieved under certain federal investigations, it is retrieved to determine the need for or facilitate emergency medical response, or it is retrieved for traffic safety research without identifying information.

That statute is about EDR data. Insurer app and device data sits under a different regime: the program's terms, the insurer's privacy statement, and whatever privacy law your state has. You consented to those terms when you enrolled. Two articles go further on the vehicle side: event data recorders: what your car records and who can access it and event data recorders as evidence in claims and fraud cases.

Consent, retention and what you agreed to

Three terms in a program decide how exposed you are.

Consent. Enrollment is voluntary, but you accepted the terms. The FTC's January 2026 final order against General Motors shows how regulators treat enrollment that is not clear: the FTC alleged GM used a misleading enrollment process and did not clearly disclose that precise geolocation and driving behavior data were being collected and sold. The order requires affirmative express consent for the 20-year term, a way for consumers to request a copy of their data and ask for deletion, and a five-year bar on disclosing the data to consumer reporting agencies. That order binds GM; it does not set a rule for your insurer, but it shows what regulators think clear consent means.

Retention. Progressive's statement says it keeps driving data on its servers indefinitely, while the app keeps driving and phone data on the phone for several days. Consumer Reports found that several insurers say they can keep information as long as they wish. A long retention period increases the chance that old data is still around when a dispute starts, and it also means you can usually find your own records.

Sharing. Progressive's statement lists service providers, state insurance departments (to support renewal rates), other insurers and litigation parties in claims, and says it may share de-personalized data more broadly. State Farm's Drive Safe & Save page says it does not sell your information and may share it with third parties in limited situations. Compare the wording in your own program.

How to ask for your data

You are entitled to see some of it, and getting it before a dispute is useful. Do this now rather than after a crash.

1. Log in to your insurer's account or app. Progressive's statement says policyholders can view driving reports by logging in at progressive.com, in the agent portal, in the Progressive app or in the Snapshot app.
2. Save screenshots or exports of the trip log and score, with dates.
3. If you need more than the dashboard shows, send a written request to the insurer's privacy contact for a copy of the data it holds about you. Say which program, which policy number, and which date range.
4. Ask in the same message what its retention period is and how to request deletion. The Snapshot statement does not describe a deletion process and refers readers to the general privacy policy.
5. Your state's privacy or insurance data law may give you more rights. Who protects your insurance data: GLBA, state acts and your rights explains the federal and state frameworks, and your state insurance department can tell you what applies where you live.

If you are leaving the program, see leaving a telematics program: what happens to your data and discount before you delete the app, because deleting it can end the discount and does not necessarily delete the data the insurer holds.

A rear-end collision, step by step

Here is a hypothetical to show how the same kind of data cuts different ways. The numbers are made up for illustration.

Dana is enrolled in a phone-based program. Three versions of one afternoon follow.

The pattern is that the data does the most work where it matches or contradicts a story. In scenario A the following driver is commonly treated as the one at fault even without data; the data affects how strongly. In scenario B, a hard-braking flag from the app might be raised in a dispute; the surrounding speed and the video from a dashcam, if any, give it context. In C it protects the driver.

After any of these, what you do in the first days matters:

1. Do not delete the app or uninstall the device before you have a copy. Progressive's statement says its app keeps driving and phone data on the phone for only several days, so the server copy may be the only one left.
2. Report the crash and tell the adjuster honestly what happened. The data will be compared with your account; a mismatch is more damaging than an unfavorable fact.
3. Save screenshots of the trip, with dates. Do not edit or annotate originals.
4. If there are injuries, a disputed fault, or a lawsuit threat, talk to a licensed attorney before giving a recorded statement or handing over device data, because the question of what to produce and when is a legal one.
5. Use the after-accident checklist and information form for the scene steps that are not data-related.

Common questions

Can an insurer cancel my policy because of what the data shows after a crash?

The program pages cited here describe pricing consequences, such as a smaller discount or a higher rate, and do not describe cancellation as a consequence of driving data. Whether a company may cancel or decline to renew is governed by your state's rules, which vary. If a notice cites your driving data, ask for the reason in writing and contact your state insurance department.

Can police get my telematics data?

Progressive's statement says data may be shared as legally required, naming subpoenas and police investigations, and device data may be shared with law enforcement in theft reports. The legal process needed depends on the state and the data, and a lawyer can advise on a specific request.

If I quit the program, is my old data protected?

Not automatically. Retention is set by each insurer's statement, and Progressive says it keeps server data indefinitely. Leaving ends future collection; it does not necessarily delete the past. See the article on leaving a program.

Can I use my own data to prove I wasn't at fault?

Yes, if you can get a copy. Ask the insurer for the trip record and save it. An adjuster or your attorney can then decide how to use it.

Do other kinds of vehicle data work the same way?

Not exactly. Connected-car data held by the manufacturer follows its own terms; see connected-car data, data brokers and your premium and driving data privacy lawsuits. Cases and rules are changing, so check the current position with your state regulator.

Key takeaways

• Driving data collected for a discount can be used in a claim, and some programs say so in their privacy statements; read yours.
• The data is evidence of speed, braking and timing, and it can help you as much as hurt you.
• In a lawsuit, the other side can seek the data through discovery from you or by subpoena to your insurer, subject to relevance and burden limits.
• An event data recorder is a separate system with its own federal ownership and access rules; app and device data fall under the program terms.
• Get your trip records now, preserve them after a crash, and ask for any denial reason in writing, citing the policy provision.
