What Not to Tell Your Insurance Company (The Honest Answer)
Hiding facts from a car insurer is fraud, not strategy. What you must disclose, what you can decline to guess at, and what your VIN already shows.

California lists fraud or material misrepresentation as the first of only three grounds on which an auto policy can be canceled or non-renewed, and can rescind the policy back to its start date - paying none of your losses and refunding the premium - if you knowingly gave false information when you applied. You must disclose household drivers, where the car is kept, how you use it, and each vehicle by VIN. What you are not obliged to do is guess: about fault, about injuries, about anything you do not actually know.
- The question assumes a negotiation. An application is a signed statement: California names fraud or material misrepresentation as the first of only three grounds for canceling or non-renewing an auto policy, and rescission cancels it back to day one with no losses paid.
- California lists only three grounds on which an auto policy can be cancelled or non-renewed once issued, and "Fraud/material misrepresentation" is the first one.
- Texas spells out the cost of a quiet omission: the company bills you the extra premium you should have paid, and "might deny any claims you have or choose to not renew your policy."
- Answering honestly is not the same as volunteering. You owe accurate facts; you do not owe a verdict on fault or a medical opinion, and the other driver's insurer is not your contract counterparty.
- The insurer already sees the file. C.L.U.E. Auto holds up to seven years of personal auto claims and returns information on "the driver, vehicles, policy and reported claims" — the vehicle side of it keyed to the VIN you wrote on the application.
The question is backwards: an application is a signed statement, not an opening offer
People search for what not to tell an insurer because they assume rating is a haggle. It is not. States require fraud warnings on insurance forms - New York's statute prescribes the wording, and it uses a different notice for automobile insurance than for other lines. The automobile notice is about knowingly making, or helping to make, a false report of the theft, destruction, damage or conversion of a motor vehicle, and it carries a civil penalty "not to exceed five thousand dollars and the value of the subject motor vehicle or stated claim for each violation."
Note what an application is. It is a signed statement, and the facts on it - the garaging ZIP code, the household driver list, how the car is used - are the facts the price is built from. "Material" means a fact that affects the decision to insure you or the price, which is exactly what those are.
The civil consequence is separate from the criminal one and it is worse in practice. The California Department of Insurance defines rescission as "the cancellation of a policy back to its start date. If this happens, the insurance company does not pay for any of your losses, and your premiums are refunded. This can happen if you knowingly gave false information when you applied for the policy." A refunded premium is no comfort when the loss you were counting on is uncovered.
What you are required to disclose
The disclosure list is not a secret. State insurance departments publish it, because the same facts are what the rate is built from. California's consumer guide sets out what an application asks for; Texas explains why each item moves the price.
| What you must disclose | What the state guide says | Source |
|---|---|---|
| Every driver in the household | "Some companies require you to put everyone who lives with you and is of driving age on your policy." | Texas Department of Insurance |
| A child away at school | "Tell your insurance company if you have a child living in another city for school." | Texas Department of Insurance |
| Where the car is kept | "Where you keep your car. Rates are higher if you live in a city... Rates can also vary between ZIP codes in the same city." | Texas Department of Insurance |
| How you use the car | "Your rates will be higher if you drive your car to and from work or use it for business." | Texas Department of Insurance |
| Annual mileage | The application asks "how many miles you drive in a year." | California Department of Insurance |
| Each vehicle by VIN | The application asks for "the years, makes, models, and vehicle identification numbers for all cars in the household." | California Department of Insurance |
| Driving and claims record | The application asks for "the driving record for all drivers in your household including accidents, insurance claims, and tickets for moving violations." | California Department of Insurance |
| Changes after the policy starts | "Tell your agent, broker, or insurance company if you sell or buy a car or have new drivers in your household." | California Department of Insurance |
What you are not obliged to volunteer
Accuracy is the duty; narration is not. Texas tells claimants to call the company, "explain what happened and answer questions as thoroughly as possible" — answer the questions asked, with facts you actually have. Nothing in a state consumer guide asks you to assign legal fault, estimate the other car's damage, or characterize an injury you have not had examined. "I don't know yet" is an accurate answer, and it is the one that stays true later.
There is also a distinction worth keeping straight between your insurer and the other driver's. Texas puts it directly: "You don't have a contract with the other driver's insurance, so you don't have the same options you would with your own company." Your policy's cooperation duty runs to the company you pay — Texas notes a company can shorten its nonrenewal notice if you don't cooperate in a liability claim. The other carrier's adjuster is working a file for its policyholder, not for you. If that carrier refuses to pay, Texas's advice is to "ask for their reason in detail and in writing."
Whether you must give a recorded statement to the other driver's insurer depends on your state and your own policy language, and neither the Texas nor the California consumer guide states a general rule either way. Anyone who tells you there is a nationwide answer to that is selling something.
The insurer already has the history — and part of it is keyed to your VIN
Most of what people hope to leave off the form is already in a database the underwriter queries. LexisNexis describes its Comprehensive Loss Underwriting Exchange as "a claim history information exchange containing up to seven years of personal automobile claims information," and says that on an inquiry it returns "a C.L.U.E. report that contains vital information about the driver, vehicles, policy and reported claims." The company markets renewal products to help carriers "identify undisclosed drivers, missing violations and undetected claims" — that is the vendor's own description of the gap an omission creates, and of the tool that closes it. LexisNexis states that 99.6% of the auto industry contributes claims activity to C.L.U.E.; that figure is the vendor's own, not a regulator's.
Because C.L.U.E. Auto is sold as "a consumer reporting agency product... [that] may only be accessed in compliance with the Fair Credit Reporting Act, 15 U.S.C. 1681," you can read your own file. Texas says most companies use C.L.U.E. to learn your claims history, that a company "can charge you more or refuse to sell you a policy based on the information in your CLUE report," and that "you can get a free copy of your report each year" by calling LexisNexis at 866-312-8076. Reading it before you apply is the legitimate version of controlling what the insurer knows.
The vehicle has its own paper trail alongside yours. The National Motor Vehicle Title Information System is a U.S. Department of Justice program — "NMVTIS is a DOJ program and DOJ is fully responsible for NMVTIS policy and operations" — whose stakeholder communities include states, insurance carriers, auto recyclers, and junk and salvage yards. The system is "designed to protect consumers from fraud and unsafe vehicles and to keep stolen vehicles from being resold", and what it holds is attached to the 17 characters of the VIN, not to your memory of them.
What actually happens when the story and the file disagree
The consequences are graded, and only the last one is dramatic. Texas describes the ordinary case of an undisclosed driver: "the company will bill you for the extra premium you should have paid. The company also might deny any claims you have or choose to not renew your policy."
| What the insurer can do | The rule as published | Source |
|---|---|---|
| Bill the back premium | "The company will bill you for the extra premium you should have paid." | Texas Department of Insurance |
| Deny the claim | The company "might deny any claims you have." | Texas Department of Insurance |
| Cancel the policy | "A company must give you 10 days' notice before it cancels your policy. A company may cancel your policy in the first 60 days for any reason, unless the cancellation violates a law." | Texas Department of Insurance |
| Non-renew the policy | As TDI's guide states it, with notice periods keyed to the year the policy was bought or renewed: 60 days' notice for a policy bought or renewed in 2024, 30 days for 2023 or earlier; a policy can only be non-renewed after it has been in effect 12 months. | Texas Department of Insurance |
| Cancel or non-renew for cause | "There are only three reasons an automobile policy can be canceled/non-renewed once it is issued: Fraud/material misrepresentation; Non-payment of premium; or Substantial increase in the hazard insured against." | California Department of Insurance |
| Rescind back to day one | "The cancellation of a policy back to its start date... the insurance company does not pay for any of your losses, and your premiums are refunded." | California Department of Insurance |
The check that actually helps before you insure a car
A VIN check will not lower your premium and it cannot tell you what an underwriter will charge. What it does do is settle the vehicle facts you are about to certify on an application — and the facts that decide whether physical-damage coverage is even available. A car carrying a salvage or rebuilt brand, a recorded total loss, or an open theft record is a different insurance proposition from an identical-looking clean-title car, and you would rather learn that from the VIN than from a declined quote or a denied claim.
Run the 17-character VIN off the dashboard and door jamb — not off the listing — before you sign anything. Then order your own C.L.U.E. report so the personal half of the file is no surprise either. Between the two, you know what the insurer knows, which is the only workable version of the question this page is named after.
Buyer checklist
- List every licensed driver who lives at your address, including a student away at school, before the agent asks.
- Give the ZIP code where the car actually spends the night, not a relative's or a parent's.
- State the real use: commuting, business, delivery or rideshare — Texas notes rates are higher for commuting and business use.
- Read the 17-character VIN off the dashboard and driver's door jamb and put that on the application yourself.
- Review the application before signing it; California's guide says not to sign forms you do not understand and not to sign blank forms.
- Order your free annual C.L.U.E. report from LexisNexis (866-312-8076) so you see the claims file the underwriter sees.
- Report changes in writing and keep a copy: a new car, a new driver, a move, a change in how the car is used.
What this research cannot prove
- Insurance is regulated state by state. The Texas and California rules quoted here are examples of how departments of insurance state the duty, not a national code — check your own state's department for the version that binds you.
- The $5,000 penalty is the figure in the automobile notice at New York Insurance Law section 403(e); the wording quoted on many other insurance forms is 403(d), which covers commercial, accident and health lines. Other states use their own statutes, warnings and penalty amounts.
- This is consumer information, not legal advice. If an insurer has alleged misrepresentation against you or is rescinding a policy, that is a question for a lawyer or your state insurance department's complaint process.
- A vehicle history report covers the car, not you. Title brands, total-loss records and theft records attach to the VIN; your own claims history lives in your C.L.U.E. file and is obtained separately.
- No VIN check reveals what an insurer will charge, what its underwriting rules are, or whether a specific carrier will write the risk.
- The Texas non-renewal notice periods are quoted as TDI's guide states them, keyed to the year a policy was bought or renewed; those years may have moved since the guide was written.

Frequently asked questions
Is it illegal to lie to your car insurance company?
It costs you the coverage, which is the part every state guide documents. California names fraud or material misrepresentation as the first of only three grounds on which an auto policy can be canceled or non-renewed, and defines rescission as cancellation back to the start date, with no losses paid and the premium refunded, "if you knowingly gave false information when you applied for the policy." New York's automobile fraud notice carries a civil penalty up to $5,000 plus the value of the vehicle or stated claim. Whether a given lie is also a crime turns on your state's penal code and on what was falsified.
Do I have to tell my insurer who else lives with me?
Usually yes. Texas states that "some companies require you to put everyone who lives with you and is of driving age on your policy," and that if the company finds out later it will bill the extra premium and may deny claims or non-renew. California's application asks for the names, ages, marital status and license numbers of all household drivers.
Can my insurer cancel my policy for something I got wrong on the application?
It can. California lists "Fraud/material misrepresentation" as one of only three grounds for cancelling or non-renewing an auto policy once issued. In the more serious case the insurer rescinds — cancels back to the start date, pays none of your losses and refunds the premium — which California's guide says can happen if you knowingly gave false information when you applied.
Does my insurance company see the car's VIN history?
It sees more than the VIN. C.L.U.E. Auto holds up to seven years of personal auto claims and returns "information about the driver, vehicles, policy and reported claims" on an inquiry. Separately, NMVTIS is a U.S. Department of Justice program whose reporting stakeholders include insurance carriers, auto recyclers and junk and salvage yards, and it is "designed to protect consumers from fraud and unsafe vehicles and to keep stolen vehicles from being resold".
Do I have to talk to the other driver's insurance company?
Your cooperation duty runs to your own insurer, the company you have a contract with. Texas puts the difference plainly: "You don't have a contract with the other driver's insurance, so you don't have the same options you would with your own company." Whether you must give that carrier a recorded statement depends on your state and policy; no state guide we found states a national rule.
