How Long Does an At-Fault Accident Affect Your Car Insurance?
You caused a crash, your renewal went up, and now you want to know when it comes back down. The answer has two parts: how long your state lets an insurer surcharge the accident, and how long the accident stays visible in the records insurers check. They are not the same number. This page is part of our car insurance life events guides.
Key takeaways
- Of the states that publish a period, North Carolina and California both use three years. North Carolina's surcharge period for accidents is exactly three policy years.
- Massachusetts looks back over a six-year experience period but assigns no surcharge points for incidents in the sixth year.
- California drivers can lose the Good Driver Discount for three years after one at-fault accident plus any other point.
- Claims databases such as CLUE can hold up to seven years or more of history, according to Florida's Department of Financial Services.
- Insurance points and license points are separate systems with different clocks.
How long do insurers surcharge an at-fault accident?
There is no national rule. Each state sets its own, and many leave it to the insurer's filed rating plan. Three states publish specifics.
North Carolina runs a state-defined Safe Driver Incentive Plan. Its experience period is "the three-year period preceding either the date an individual applies for coverage or the insurance company prepares to renew an existing policy," and for accidents the surcharge period is "not less nor more than THREE policy years."
Massachusetts insurers may use the state's Safe Driver Insurance Plan or their own merit rating plan. Under the SDIP, the policy experience period is six years, but "no surcharge points are assigned for incidents in the sixth (oldest) year." A "Clean in 3" rule reduces each incident's points by one if your most recent surcharge date is at least three years old and you have three or fewer incidents in five years.
California ties pricing to the Good Driver Discount. Under Insurance Code § 1861.025, you qualify only if, during the previous three years, you did not have "more than one violation point count." A principally at-fault accident with only property damage adds "one violation point count," and an at-fault accident causing bodily injury or death disqualifies you for the period.
| State | Window the insurer looks at | How an at-fault accident counts | Source |
|---|---|---|---|
| North Carolina | 3 years before application or renewal | 1 to 3 SDIP points by damage, surcharged for 3 policy years | NC DOI |
| Massachusetts (SDIP insurers) | 6-year experience period, no points in year 6 | Minor accident 3 points, major 4 points | Mass.gov |
| California | Previous 3 years | 1 point for property-damage-only; injury accident disqualifies Good Driver Discount | Ins. Code § 1861.025 |
How big is the surcharge while it lasts?
Of these three states, only North Carolina publishes the percentages. An at-fault accident with total property damage of $2,300 or less is 1 point and a 40% increase; more than $2,300 but under $3,850 is 2 points and 55%; $3,850 or more, or bodily injury over $1,800, is 3 points and 70%. There is no point at all for a property-damage-only accident of $2,300 or less if there was no moving-violation conviction and no licensed driver in the household had a conviction or at-fault accident in the experience period.
Massachusetts classifies a minor at-fault accident as a claim payment "of more than $1000 and up to and including $5000," and a major one as "more than $5000." Points translate into money through your insurer's plan, so ask your insurer for its table.
Why does the accident still show up after the surcharge ends?
Because the surcharge rule and the record are different things. Florida's Department of Financial Services says a CLUE report "generally contains up to seven years (or more) of personal-auto and personal-property claims history," including date of loss, type of loss and amounts paid. The Texas Department of Insurance notes that "most insurance companies get a report from the Comprehensive Loss Underwriting Exchange (CLUE) to learn your claims history," even for claims filed with another company.
So a new insurer can see an accident after your state's surcharge window closes. How it uses that history depends on its rating plan and your state's rules. You can request your own CLUE report for free once a year; Texas lists 866-312-8076.
Check your report: If a claim on your CLUE report is wrong, Florida DFS says to contact LexisNexis Consumer Center at 888-497-0011. You can also add an explanation that will show in future reports.
Insurance points vs license points: what is the difference?
They are two systems run by different bodies, on different clocks.
License points are assigned by the DMV. In New York, "the points for violations that all occurred within the last 24 months are added to calculate your point total," and 11 points in 24 months can lead to suspension. California's DMV adds negligent operator points when law enforcement reports show you were responsible for a collision; such collisions are generally counted as 1 point.
Insurance points are assigned by insurers under a state plan or their own rating plan. New York's DMV says so directly: "Insurance companies have their own point systems and can increase your premiums based on your driving record." It adds that after 24 months, points stop counting toward your DMV total, but "the points remain on your driving record as long as the conviction remains on your record and may be used by your insurance company to increase premiums."
California goes further and separates the two by regulation. Insurers determining fault "may not rely on a traffic violation point count" from the DMV, and must make their own principally-at-fault determination.
| License points | Insurance points | |
|---|---|---|
| Who assigns them | State DMV | Insurer, under a state plan or its own filed plan |
| What they decide | Warning letters, suspension, fees | Your premium and discounts |
| NY clock | 24 months toward suspension total | Insurer's own plan; conviction stays on record |
| NC clock | DMV system | 3-year experience period for accidents |
Can you shorten how long an accident affects your rate?
You cannot erase the accident, but a few published levers exist.
- New York's PIRP course saves "10 percent on your automobile liability and collision insurance premiums" and reduces points for suspension purposes, though "the tickets/points do not physically come off your driving record."
- Challenge the fault finding. California insurers must send written notice and give you 30 days to request reconsideration. Massachusetts publishes an appeal process for at-fault determinations.
- Check the thresholds. In California, a property-damage-only accident cannot be held against you as principally at fault unless total damage "exceeded $1000." In Massachusetts, the claim payment must be "more than $1000, in excess of any deductible." If yours was below those lines, ask why it was surcharged. Our should I file a claim or pay guide covers this decision before it happens.
- Shop at the right moment. When the accident ages past your state's window, ask for new quotes rather than waiting for your current insurer to adjust.
Does a DUI follow you longer than an accident?
Often, yes. North Carolina is a clear example. Driving while impaired is 12 SDIP points and a 340% increase, and for convictions of 4 or more points occurring on or after July 1, 2025 (other than speeding), the experience and surcharge periods are five years instead of three. See how long a DUI affects insurance for the full picture.
If your rate went up and you are not sure the accident is the reason, start with why your car insurance went up in 2026. Then compare what other insurers would charge with your current record.

Frequently asked questions
Does an at-fault accident affect insurance for 3 or 5 years?
In North Carolina, three policy years for accidents. In California, the Good Driver Discount looks back three years. Massachusetts SDIP insurers look back up to five years for points, within a six-year experience period. Other states leave the period to the insurer's filed plan, so ask your insurer.
Do not-at-fault accidents count?
Under the state plans above, surcharges apply to at-fault accidents: more than 50% at fault in Massachusetts, at least 51% in California. Insurers may still see the claim in CLUE.
Will my rate drop automatically when the accident ages off?
In North Carolina the surcharge period is fixed at three policy years, so it should come off at the renewal after that. Elsewhere, check your renewal and ask your insurer to confirm the accident is no longer rated.
Does an out-of-state accident count?
It can. Massachusetts says accidents "outside of Massachusetts may be subject to surcharge." California's DMV may add a point for an out-of-state collision once responsibility is determined.
Do license points from a ticket in the accident add to the insurance hit?
They can add to it under a separate rule. In North Carolina, moving-violation convictions carry their own SDIP points. In Massachusetts, traffic violations are separate surchargeable incidents.
