Research Summary
What Actually Moves the Needle
Repairing identical hit-and-run damage through standard Collision coverage raises annual premiums by roughly $435 on average, versus roughly $98 through Uninsured Motorist Property Damage coverage.
The Consumer Federation of America found moderate-income drivers hit by another car absorbed an average 9.6% ($208/year) not-at-fault surcharge, versus 6.6% ($78/year) for higher-income drivers with an identical claim.
A claim stays on the LexisNexis C.L.U.E. claims-history report for seven years under federal law, regardless of fault — longer than most state DMV records keep accident history on file.
Why an Innocent Driver Can Still See a Rate Increase
Auto insurance is a system of pooled risk: premiums collected from every policyholder pay the claims of the few who file them. To price that risk, insurers lean on two variables — claim frequency, how often a driver generates a claim, and claim severity, how much that claim costs to pay out. Actuarial data shows that a driver who has been in an accident, regardless of who caused it, is statistically more likely to be in another one, so an insurer’s pricing algorithm can treat the mere existence of a claim on file as a forward-looking risk signal rather than a verdict on that driver’s behavior.
That mechanism produces a rate increase through two separate channels. The first is a direct base-rate surcharge applied at renewal. The second, subtler channel is the loss of a “claims-free” or “safe driver” discount — a credit some carriers apply for going a set number of years without filing any claim, at-fault or not. Filing a claim to fix damage a stranger caused can strip that discount at the next renewal, and the net effect on the bill looks identical to a penalty even though the insurer never called it one.
At-Fault vs. Not-At-Fault: The Two Numbers That Matter
Fault still does the most work in determining how steep any increase is. When a driver is found at fault, their insurer is legally on the hook for the other party’s medical bills and property damage up to the policy limits — a liability so large that at-fault accidents trigger the steepest hikes in the industry, typically 34% to 50% depending on the state and the severity of the crash. A not-at-fault accident produces a much smaller bump when a carrier applies one at all: national data puts the range at roughly 4% to 22%, still a real cost but a fraction of what an at-fault driver absorbs.
Where a state falls on fault-sharing law changes how easily a not-at-fault driver can be pulled partway into that steeper bracket. In a pure comparative negligence state, an insurer can assign a driver 10% or 20% shared fault for something as small as a slow reaction time, and apply a partial surcharge proportional to that share. In a pure contributory negligence state — North Carolina, Virginia, Maryland, Alabama, and Washington, D.C. — being found even 1% at fault bars a driver from recovering anything from the other party’s insurer at all, forcing them onto their own coverage and the rate consequences that follow.
Does Your State Ban a Not-At-Fault Surcharge?
Insurance is regulated state by state, not federally, so whether a carrier can legally raise a not-at-fault driver’s rate depends entirely on where that driver is licensed. Eight states have enacted statutes or regulations that specifically restrict the practice, each drawing the line for “at fault” a little differently.
State-by-State
States That Restrict Not-At-Fault Surcharges
| State | Rule | Statute |
|---|---|---|
| California | Bars a surcharge or loss of the 20% Good Driver Discount unless the driver is "principally at fault" — at least 51% responsible for damage exceeding $1,000. | Cal. Code Regs. tit. 10, § 2632.13 (Prop. 103) |
| Oklahoma | Absolute ban: no points, cancellation, non-renewal, or premium increase for a not-at-fault collision or comprehensive claim. | Okla. Stat. tit. 36, § 941 |
| Georgia | No surcharge for a not-at-fault multi-vehicle accident — unless the driver has three or more not-at-fault accidents or UM claims within a rolling 36 months. | O.C.G.A. § 33-9-40 |
| Florida | Bars a surcharge on liability, PIP, medical payments, or collision coverage "solely because" of an accident, unless the insurer's file shows the driver was substantially (more than 50%) at fault. | Fla. Stat. § 626.9541(1)(o)(3)(a) |
| New York | Bars a surcharge unless the accident caused more than $2,000 in aggregate property damage or any bodily injury — but pure comparative negligence still lets an insurer apply a partial surcharge for shared fault. | N.Y. Ins. Law § 2335 |
| Massachusetts | The Safe Driver Insurance Plan lists specific crash types carrying a rebuttable presumption of fault (e.g., rear-ending another car, striking a parked vehicle); a surcharge only attaches if the driver is found more than 50% at fault on a claim over $1,000. | 211 CMR 134.00 (SDIP) |
| Virginia | No premium increase or safe-driver point loss unless the crash was caused wholly or partly by the insured or a customary operator; a driver can appeal a rate increase to the State Corporation Commission within 60 days. | Va. Code § 38.2-1905 |
| Maryland | An insurer cannot cancel or refuse to renew based on claims history when two or fewer of the claims in the preceding three years were not-at-fault; any accident-based rate action requires 45 days’ written advance notice. | Md. Code, Ins. §§ 27-501(k), 27-613 |
Most of the country has no such statute. Texas, Illinois, and North Carolina are illustrative: none of the three bans a not-at-fault surcharge outright, so carriers remain free to price a driver’s claim history and geography however their own underwriting guidelines allow.
State-by-State
States With No Statutory Ban
| State | What This Means |
|---|---|
| Texas | No statute bars a not-at-fault surcharge. Insurers may weigh a driver's claim history and location — a minor not-at-fault claim can add roughly $200 a year at renewal. |
| Illinois | No blanket ban. Filing an Uninsured Motorist claim after a hit-and-run can still classify a driver as higher-risk and trigger a base-rate increase, especially in dense urban ZIP codes. |
| North Carolina | Regulators generally block insurers from assigning driving-record "points" for a single not-at-fault accident, but carriers can still strip a claims-free discount or cite claim frequency after repeat incidents. |
The Parked Car Scenario
A legally parked, turned-off, unoccupied car is assigned 0% fault in the vast majority of collisions — the exception is a car parked illegally, such as blocking a fire lane or protruding into traffic, where the owner can be assigned partial or total fault for creating the hazard in the first place.[11] Assuming the parking itself was legal, what happens next splits into two very different outcomes depending on one fact alone: does anyone know who did it?
If the driver who hit the parked car stays at the scene, or leaves a note with contact and insurance information, the owner files a third-party claim directly against that driver’s property damage liability coverage. No money comes out of the parked car owner’s own policy, so their rate almost never moves.[11] If the driver flees and leaves no trace, the owner has no third party to bill. Repairing the car then requires a first-party claim against their own Collision or Uninsured Motorist Property Damage coverage — and filing that claim, even though the owner did nothing wrong and was nowhere near the car, is the event that can trigger a rate increase at the next renewal.[12]
Michigan runs a completely different system for this exact scenario. Under Michigan Compiled Laws § 500.3121, every driver carries Property Protection Insurance (PPI) — a no-fault coverage that pays up to $1 million for damage a moving vehicle causes to parked, unoccupied property, including another driver’s car.[13] A Michigan driver whose legally parked car is struck pays no deductible at all — the moving driver’s PPI covers the repair directly, regardless of whether that driver can be identified. The one exception: if the owner is sitting inside the car when it is hit, the vehicle is no longer legally “unoccupied property,” and PPI no longer applies.
Collision vs. UMPD: Which Coverage Costs You Less at Renewal
When an unidentified driver causes the damage, two different coverages can pay for the repair, and underwriters do not treat them the same way. Collision coverage pays for impact damage regardless of fault, but because the insurer is paying from its own reserves for a physical-object collision, filing a standard Collision claim routinely triggers a bigger rate increase or a stripped claims-free discount at renewal.[14] Uninsured Motorist Property Damage (UMPD) coverage is written specifically for damage caused by an uninsured or unidentifiable driver, and insurers generally price it more gently because the loss is inherently a not-at-fault event caused by a negligent third party. Industry data shows a UMPD claim raising rates by roughly $98 a year on average, compared with roughly $435 a year for the same dollar amount of damage paid through standard Collision coverage.[15]
The catch is availability. UMPD is not sold everywhere, and where it is sold, the rules for using it after a hit-and-run vary sharply by state.
Coverage Availability
UMPD Availability by State
| States | UMPD Status | Note |
|---|---|---|
| Maryland, Virginia, North Carolina, South Carolina, Vermont, West Virginia, D.C. | Required by law | State-mandated minimum limits (e.g., $15,000 in Maryland, $50,000 in North Carolina). |
| California, Texas, Illinois, Colorado, Georgia, Louisiana, Ohio, Washington | Optional, must be offered | Insurer must offer it; some states let the driver reject it in writing. |
| Florida, New York, Pennsylvania, Michigan, Massachusetts, Nevada | Not offered | Drivers must rely on Collision coverage for unidentified hit-and-run damage instead. |
Some states also restrict how UMPD applies to a hit-and-run specifically. California and Illinois require the at-fault driver to be identified before UMPD can be used at all — if the driver is unknown, the claim defaults to Collision coverage instead. Colorado requires physical contact between the vehicles, ruling out a “phantom vehicle” claim where a driver swerves to avoid a car that never actually touched them, while Arizona allows exactly that scenario if there is corroborating evidence such as witness testimony or surveillance footage.
The Database That Remembers Every Claim
Every claim filed anywhere — a third-party liability payout, a first-party Collision claim, a UMPD claim — gets recorded in a shared industry database. The dominant one is the Comprehensive Loss Underwriting Exchange (C.L.U.E.), operated by LexisNexis and populated voluntarily by roughly 99.6% of the U.S. auto insurance market.[17] Whenever a driver applies for a new policy or comes up for renewal, the underwriter pulls this report to price risk — and it tracks the vehicle’s date of loss, loss type, fault determination, and payout amount for seven years from the date of the claim, regardless of who caused it and regardless of whether the insurer paid anything at all.[18]
Seven years is significantly longer than most state DMV driving records retain accident information, which typically fall off after three to five years. A minor, fully not-at-fault claim that has already disappeared from a driver’s official state record can still be sitting on their C.L.U.E. report, quietly shaping quotes from every insurer they shop with for years afterward.[18] Because C.L.U.E. reports are compiled by a consumer reporting agency, they fall under the federal Fair Credit Reporting Act, which gives every driver the right to one free copy annually and the right to formally dispute inaccurate entries — LexisNexis must investigate a dispute within 30 days or remove the unverified data.[17]
Deciding Whether to File the Claim at All
For minor damage, drivers often face a genuine math problem rather than an obvious choice. Filing a Collision or UMPD claim usually means paying a deductible — often $500 to $1,000 — before the insurer pays anything, and it risks a 10% to 20% premium increase spread across the next three to five years of renewals. A driver quoted $800 to fix a bumper who would net only $300 after a $500 deductible may end up paying more in accumulated surcharges over three years than the repair itself would have cost out of pocket. Not filing at all keeps the incident off the C.L.U.E. report entirely.
Accident Forgiveness endorsements offer a partial fix, guaranteeing that a driver’s current insurer will not raise their base premium after a first accident, at-fault or not, if the driver had a clean record for a set number of years beforehand. The protection does not follow the driver to a new carrier: the claim still appears on the C.L.U.E. report, and a new insurer evaluating that history within the next five to seven years will not honor forgiveness it never granted.
In any state that uses comparative negligence, an insurer investigating a claim can try to assign a slice of fault to the innocent party to justify a surcharge or reduce a payout. The strongest defense against that outcome is evidence gathered at the scene — the full police crash report, photos, intersection or parking-lot surveillance footage, and independent witness contact information — collected before memories fade and cameras overwrite their storage.
Frequently Asked Questions
If someone hits my car, will my insurance go up?
It can. Filing any claim, even for damage you did not cause, gets logged in the industry's shared claims database and can flag you as a higher statistical risk. National data shows a not-at-fault accident raises rates by roughly 4% to 22%, though eight states legally ban insurers from surcharging a driver who was not substantially at fault.
Why would my rate go up if I did not cause the accident?
Insurers price risk using claim frequency, not just fault. Actuarial data shows a driver who has been in any accident — regardless of who caused it — is statistically more likely to be in another one, so some carriers treat the claim itself, and the loss of a claims-free discount, as a pricing signal.
Does my rate go up if my parked car is hit?
Not if the at-fault driver is identified — that becomes a third-party claim against their liability coverage and does not touch your rate. If the driver flees and leaves no note, repairing the damage requires a first-party Collision or Uninsured Motorist Property Damage claim against your own policy, which can trigger a rate increase at renewal.
Is Collision or Uninsured Motorist Property Damage better for a hit-and-run claim?
UMPD is generally treated more favorably by underwriters because it is inherently a not-at-fault loss caused by a negligent third party. Industry data cited by The Zebra shows a UMPD claim raising rates by roughly $98 a year on average, compared with roughly $435 a year for the same damage paid through standard Collision coverage.
Which states ban insurers from raising rates after a not-at-fault accident?
California, Oklahoma, Georgia, Florida, New York, Massachusetts, Virginia, and Maryland all have statutes or regulations restricting not-at-fault surcharges, though the exact threshold for what counts as "at fault" varies by state. Texas, Illinois, and North Carolina have no such statutory ban.
Does a claim still count against me if the insurer pays nothing?
Yes. The LexisNexis C.L.U.E. database logs an inquiry as an open or closed claim even when the payout is zero or the claim is withdrawn, and that record stays on file for seven years under the Fair Credit Reporting Act — longer than most state DMV records retain accident history.
