When someone else totals your car: first-party vs third-party routes

You have two routes when another driver's mistake totals your car. You can make a claim against the at-fault driver's liability insurer (a third-party claim), or you can use your own collision coverage (a first-party claim) and let your insurer chase the other company for the money. The third-party route costs you no deductible, but the other insurer decides how fast it moves and you are negotiating with a company that owes you nothing under contract. The first-party route is faster and gives you a contract to enforce, but you pay your deductible up front and wait to get it back.

Neither route is the "right" one in every case. Which is better depends on how clear the fault is, how much the other driver's policy carries, whether you bought collision coverage at all, and how quickly you need money to replace the car. This article lays out how each route works, where the dollar differences come from, what to do when the at-fault driver's limits are too low or they have no insurance, and how to keep a claim from stalling. Rules differ by state, so check yours with the state car insurance requirements lookup and your state insurance department.

The two routes side by side

The two routes can be combined in sequence, but they cannot both pay for the same loss. As the Washington Office of the Insurance Commissioner puts it in its guide to totaled cars, if someone else is at fault and you disagree with their insurer about your car's value, you can file with your own insurer if you carry collision coverage, and it will pay for the totaled car. The background on how the two kinds of claims differ is in the guide to first-party vs third-party claims.

Route one: a claim against the at-fault driver's insurer

A third-party claim is a claim that the other driver owes you money for the harm they caused. Their insurer handles it because their policy promises to pay what the driver becomes legally responsible for, up to the policy's property damage limit.

Three things have to line up before the insurer pays.

1. It must accept that its driver was at fault. If the police report, witness statements, photos and the driver's own account point one way, this can take days. If the drivers tell conflicting stories, or the crash involved a disputed lane change or an intersection, it can take weeks and end in a split of fault. How fault gets decided is covered in the guide to how fault is determined in a car accident.
2. The insurer must value the car. You are owed the car's value immediately before the crash, which in practice means what a comparable car would cost in your area. Some states' claims regulations apply total loss valuation standards to third-party claimants as well as to the policyholder. California's regulation, 10 CCR 2695.8, says its total loss provisions apply to third-party claims but do not change existing law on what the insurer owes a third party. Whether a third-party settlement must include sales tax and title fees, and how they are calculated, depends on your state's law; ask the adjuster to state in writing what is included.
3. The insurer must pay within its state's deadlines. The NAIC's Unfair Property/Casualty Claims Settlement Practices Model Regulation (Model 902, text dated 1997 in the NAIC's library) says an insurer should affirm or deny liability within a reasonable time and tender payment within 30 days of affirming liability if the amount is determined and not in dispute. It also requires a response within 15 days to communications that reasonably call for one. States adopt their own versions, with their own day counts, so treat those figures as the model's, not yours.

The insurer may not steer you away from its own obligation

If the other driver's insurer tells you to "just go through your own insurance," it may be breaking a rule. The NAIC model regulation says that where liability and damages are reasonably clear, insurers shall not recommend that third-party claimants make claims under their own policies solely to avoid paying under the insurer's policy. Florida's claim settlement statute, section 626.9743, contains the same prohibition, with an allowance for the insurer to describe repair options. California's regulation has comparable language. The rule has a built-in limit: it applies when fault is reasonably clear. If the other insurer genuinely disputes liability, telling you its position is not a violation, and using your own coverage may be the practical answer.

Loss of use and rental

Under general damages law, an owner deprived of a car is often entitled to compensation for the loss of use during the period reasonably needed to repair or replace it, even when no rental car was actually rented. Connecticut's Insurance Department spelled this out in a 2007 bulletin on third-party loss of use, saying loss of use payments are owed even if the claimant has not incurred rental expenses, and that an offer to pay or a discussion of rental is not enough. The bulletin also says the department would look to the rental cost of similar vehicles in the claimant's area, and treats an accepted, reasonably equivalent rental as satisfying the obligation.

That is one state's regulator on one state's rules. In some states, courts limit loss of use when the car is a total loss rather than repairable, and the "reasonable period" can be short once the insurer has made a fair offer. Ask the adjuster how long they will pay for a rental, and whether that clock runs from the date of the crash or from the date they accept liability. The rental side of a total loss is covered in more detail in rental cars after a claim: reimbursement, loss of use and daily limits and the total loss timeline: from the adjuster's call to the check.

Route two: your own collision coverage

If you carry collision coverage, you can report the crash to your own insurer and have your car handled as a first-party total loss. Your insurer values the car under your policy and under your state's first-party total loss regulation. The NAIC model, for instance, lets the insurer offer a comparable replacement vehicle or a cash settlement based on the cost of two or more comparable cars available in the local market in the last 90 days, a dealer quotation or a statistically valid database, and it requires taxes, license fees and other transfer fees to be included. It also gives you the right to ask the insurer to reopen the file if you notify it within 35 days of receiving the payment that you cannot buy a comparable car for the amount paid. The details by state are in what state rules require insurers to do in a total loss valuation.

Your insurer then pays you, less your deductible, and turns to the at-fault driver's insurer to be repaid. That recovery effort is called subrogation. It is the insurer's job, not yours, and it does not hold up your payment. The mechanics are in subrogation explained: how your insurer recovers your deductible and subrogation: when your insurer sues the at-fault driver.

Getting your deductible back

The NAIC model regulation says that, on the claimant's request, an insurer must include the first-party claimant's deductible in its subrogation demand. If the recovery is partial, the model says it should be shared proportionately with the policyholder unless the deductible was recovered otherwise, and the insurer may deduct expenses from the deductible recovery only when it hires an outside attorney, and then only a pro rata share. Many insurers reimburse the deductible automatically when they recover in full; if yours does not, ask. In practice, many insurers settle inter-company subrogation through arbitration programs, described in inter-company arbitration: how insurers settle claims among themselves.

If fault is shared, you may get back only part of the deductible, or none of it. How a split such as 80/20 is handled depends on your state's negligence rule and on how your insurer's subrogation unit treats the deductible, so ask rather than assume. The question of who pays the deductible when you were not at fault is taken up in do you pay a deductible if the accident was not your fault?.

What happens to your premium

A collision claim is a claim on your record. Many states restrict surcharging a driver for a crash in which the driver was not at fault. California's regulation on the good driver discount, for example, treats a driver as "principally at fault" only at 51 percent or more, with a $1,000 damage threshold, and presumes the victim of a hit-and-run was not at fault (10 CCR 2632.13). Other states differ, and some insurers apply their own not-at-fault forgiveness, so ask how a not-at-fault collision claim would be rated. Your claims history, including who was at fault, appears in your CLUE report (Your CLUE report and motor vehicle record explained).

A worked example with made-up numbers

Say your 2019 sedan is totaled by a driver who ran a red light. Assume the comparable cars your adjuster finds support a value of $17,000 before tax and fees, you can show listings for similar cars at $18,200, and combined sales tax and transfer fees for a replacement would be about $1,400. Your collision deductible is $500. These numbers are hypothetical.

The pattern here is common: the third-party route has more upside if the insurer values the car fairly and agrees quickly, while the first-party route trades some of that upside for speed and certainty. If the other insurer's offer is slow or lowball, nothing stops you from switching to your own coverage later, provided you have not signed a release and your policy's notice and cooperation conditions are met. Run your numbers through the total loss payout estimator before you decide.

Taxes on the payment

The settlement pays you for property you lost, so for most people it is a reimbursement, not income. The IRS explains in Publication 547 (2025 edition) that if your reimbursement is more than your adjusted basis in the property, which is generally what you paid plus improvements less certain adjustments, you have a gain. For a car that has lost value since you bought it, that is unusual. The same publication says that for tax years after 2017, a personal casualty loss is deductible only if attributable to a federally declared disaster, so an ordinary crash does not produce a loss deduction. A tax professional can say whether any part of your payment is taxable.

When the at-fault driver's limits are too low

Every liability policy has a property damage limit, and it applies to everything the driver damaged in the crash: your car, other cars, a fence, a utility pole. Minimums are low in many states. California's property damage minimum is $15,000 under its 30/60/15 limits in effect since January 1, 2025, and Virginia's is $25,000 under its 50/100/25 limits for policies issued or renewed on or after January 1, 2025. A late-model car can be worth more than that on its own. Say the at-fault driver carries a $25,000 limit and your SUV was worth $31,000: their insurer will tell you the limit is the most it will pay.

Your options when the limit falls short:

1. Use your collision coverage. It pays your car's value, less the deductible, regardless of what the other driver carries. This is the simplest answer and a common reason to keep collision on a car worth more than the typical state minimum.
2. Check your policy for underinsured motorist property damage. Underinsured coverage for car damage is available in some states and sold in a few forms; in many states underinsured coverage applies to injuries only. Read the declarations page or ask your agent.
3. Ask about other coverage the driver may have. An umbrella policy, a commercial policy if the driver was working, or the policy of the car's owner if the driver was borrowing it may add to the pot. You usually learn this by asking the insurer directly and by requesting the other driver's coverage information in writing.
4. Pursue the driver for the difference. Small claims court is the usual venue for amounts under the court's limit. Verified limits as of 2026 include $12,500 for individuals in California, $8,000 in Florida, and $20,000 in Texas justice courts, with others in between. Winning a judgment is not the same as collecting it, and a driver with only minimum limits may have little else to pay with. Small claims is covered in small claims court after a car accident.
5. Watch the clock. The deadline to sue for property damage differs by state and from the injury deadline. See statutes of limitations for car accident claims.

When the at-fault driver has no insurance

Insurance Research Council estimates, published in 2025 and reported in the Insurance Information Institute's uninsured motorist fact sheet, put the uninsured driver share at 15.4 percent in 2023. If the driver who totaled your car has no coverage, the third-party route is effectively closed unless you are prepared to sue and collect. The sequence that usually works:

1. Get a police report and the driver's identifying details, including plate number and the driver's name and address. Some uninsured-motorist property damage coverage requires that the driver or the plate be identified, and some states also set a reporting deadline. California's rule, in Insurance Code section 11580.26, requires the driver or plate to be identified and a report within 10 business days.
2. Look at your policy for uninsured motorist property damage coverage (UMPD). If you have it, it pays for damage to your car caused by an uninsured driver, usually with a lower deductible than collision and a cap on the amount. uninsured motorist property damage vs collision: which to use compares the two.
3. If you have no UMPD, use collision coverage. It pays your car's value less the deductible, and the claim may count against you less than a fault claim in states that restrict surcharges on not-at-fault claims.
4. If you have neither, the claim is against the driver personally. Small claims is the realistic route. The guide to what to do after an accident with an uninsured driver walks through it.

Some states take the other side of this. In the "no pay, no play" states, drivers who were uninsured themselves can lose the right to recover certain damages, even when they were not at fault. The Insurance Information Institute lists California, Indiana, Iowa, Louisiana, Michigan, Missouri and New Jersey among them. If your own coverage had lapsed when the crash happened, ask an attorney before you assume you can sue.

How to push for a quick settlement

You cannot force an insurer to pay on the day you want, but you can remove the reasons for delay.

1. Get the claim number and the adjuster's name from the at-fault driver's insurer in your first call, and confirm in writing that you are making a property damage claim.
2. Ask for written acceptance of liability. Until the insurer accepts fault, nothing else moves.
3. Send your evidence at once: photos, the police report number, your registration, maintenance records, an options list from the window sticker or build sheet, and any receipts for recent tires, brakes or major repairs.
4. Send your own comparables. Find three or four listings for the same year, make, model and trim, with similar mileage, within your market. Include the URLs and the date you saved them.
5. Request the valuation report and a written explanation of every adjustment. If the insurer will not provide it, say you will be asking the state insurance department to review.
6. Ask for loss of use or rental in writing, and ask how long it will be paid.
7. Set a date. Tell the adjuster that if you do not have a written offer by a stated date, you will file under your own collision coverage. Then do it if the date passes.
8. Do not sign a release that mentions injuries unless you are done with those claims. A property damage release should say it covers property damage only.

If an insurer acts in bad faith or breaks its state's claims rules, the state insurance department takes complaints, though it has limits. The Washington commissioner's office notes that it cannot decide fault or set the amount owed on a claim, but it can check that the company followed the law and the policy. California's auto claims mediation program, run by the California Department of Insurance, excludes third-party liability claims, so a dispute with the other driver's insurer needs another route. Questions about suing, or about fault where someone was hurt, belong with a licensed attorney.

Questions to ask the other driver's insurer

• Has your insured's liability been accepted, and can you confirm that in writing?
• What property damage limit applies, and is it likely to cover my car and anything else damaged?
• How was my car valued, which comparables did you use, and may I have the valuation report?
• Does the settlement include sales tax and title and registration fees?
• Will you pay for a rental or for loss of use, how many days, and at what daily rate?
• If I sign a release, what exactly does it cover?
• When will payment be issued, and to whom will the check be made out?

Common questions

Do I have to use the at-fault driver's insurer?

No. You may use your own collision coverage, or you may pursue the at-fault driver's insurer. Neither is required. Some policies require you to report the loss promptly in any case, so tell your own insurer about the crash even if you plan to claim against the other company.

Will using my collision coverage make my rates go up?

It can, but a not-at-fault claim often has a smaller effect than an at-fault claim, and some states limit surcharges for not-at-fault crashes. Ask your insurer how it rates a collision claim when you are not at fault and whether the claim will be coded as not-at-fault if the other company reimburses it.

Can I get paid by both insurers?

No. Insurance pays for actual loss, and you cannot collect twice for the same car. If your insurer pays first, it takes over your right to recover from the other driver, up to what it paid.

What if the insurer's offer is less than I owe on the car?

The offer is based on the car's value, not your loan balance. If the loan is higher, you owe the difference unless you carry gap coverage. The lender is usually paid first. See what happens if your car is totaled and you still owe money and how a gap insurance claim works after a total loss.

Key takeaways

• You can claim against the at-fault driver's insurer or use your own collision coverage; you cannot be paid twice for the same loss.
• The third-party route has no deductible but depends on the other insurer accepting fault and paying fairly; the first-party route is faster but you front your deductible.
• Insurers generally may not steer you toward your own policy to avoid paying when fault is clear, a standard in the NAIC model, Florida's statute and California's regulation.
• If the at-fault driver's limit is too low or they are uninsured, collision coverage, uninsured motorist property damage and small claims court are the main fallbacks.
• Put the demands in writing, send your own comparables, ask for the valuation report and set a date after which you will switch to your own coverage.
