How Much Does Car Insurance Go Up After an Accident?
Car insurance goes up an average of 43% after an at-fault accident - roughly $600 more per year for a typical policy. The increase lasts 3 to 5 years depending on your insurer and state. Not-at-fault accidents generally should not raise your rate, though some insurers do it anyway. Knowing what to expect - and what to do about it - matters more than most drivers realize.
First Responder Insight: Rates after an accident are one of the top questions we hear from people at the scene and in the days after. The short answer: it depends heavily on your insurer, not just the accident. Some companies are dramatically more forgiving than others. Before renewing after an at-fault accident, get competing quotes - your current insurer is not always your best option anymore.
Average Rate Increases by Accident Type
Not all accidents trigger the same rate increase. Insurers factor in who was at fault, whether there was a bodily injury claim, the dollar value of property damage, and whether it was your first incident.
| Accident Type | Average Rate Increase | Annual Dollar Impact* |
|---|---|---|
| At-fault, property damage only | +28–35% | +$390–$490/yr |
| At-fault, bodily injury claim | +43–56% | +$600–$785/yr |
| At-fault, major accident (DUI, serious injury) | +75–100%+ | +$1,050–$1,400+/yr |
| Not-at-fault (most states) | 0–5% | $0–$70/yr |
| Comprehensive claim (theft, weather) | 0–3% | $0–$42/yr |

How Long Does an Accident Affect Your Insurance?
Most insurers use a 3-year lookback window when setting rates. After 3 years from the accident date, the surcharge typically drops off entirely - though the accident stays on your motor vehicle record longer.
Full rate increase applied at each renewal. This is when the financial damage is highest.
Some insurers extend surcharges to 5 years. Review your policy documents for your specific insurer's lookback window.
Most insurers no longer factor the accident into your rate. Your record resets for rating purposes, though the accident may remain on your MVR.
At-Fault vs Not-At-Fault: Does It Matter?
Fault assignment is the single biggest factor in whether your rates go up.
At-Fault Accidents
If the police report and claims investigation assign fault to you, expect a significant rate increase at your next renewal - typically at the first renewal after the accident date. The increase is permanent for 3 to 5 years; it does not fade gradually.
Not-At-Fault Accidents
In most states, if the other driver caused the crash and their insurance paid the claim, your rates should not increase. However, there are exceptions:
- Multiple claims in a short period: If you file 2 or more not-at-fault claims within 3 years, some insurers treat you as a higher risk regardless of fault.
- Certain states allow it: A small number of states permit insurers to surcharge for not-at-fault accidents under specific circumstances.
- Your own policy paid first: If you filed a claim under your own collision coverage (even for a not-at-fault accident) rather than through the at-fault driver's insurer, it may count as a claim on your record.
What to do: Always file through the at-fault driver's liability insurance when possible, not your own collision coverage. This avoids a claim appearing on your record.
Factors That Affect How Much Your Rate Increases
- Your prior driving record: A clean record before the accident results in a smaller increase than if you already had violations or claims.
- Severity of the accident: A $4,000 fender-bender raises rates less than a $40,000 injury claim.
- Your insurer: Rate-setting formulas vary significantly between companies. Progressive, GEICO, and State Farm treat the same accident differently.
- Your state: State regulations limit how much insurers can increase rates and for how long. Some states cap surcharges; others do not.
- Accident forgiveness: If your policy includes this feature (either automatically or as a paid rider), your first at-fault accident may not trigger any increase.
What Is Accident Forgiveness?
Accident forgiveness is a policy provision that waives the rate surcharge for your first qualifying at-fault accident. Most major insurers offer it - either automatically to long-tenured customers or as an optional add-on at renewal.
Key points about accident forgiveness:
- It only covers the first at-fault accident. A second forfeits the benefit.
- It does not remove the accident from your driving record - it only waives the rate surcharge with your current insurer.
- The protection does not transfer. If you switch insurers, the new insurer will see the accident and rate you accordingly.
- Some programs are automatic after a set number of years with no claims; others must be purchased as a rider (typically $30–$80/year).
How to Limit the Rate Damage After an At-Fault Accident
Shop quotes before your renewal
Your insurer will apply the surcharge at your next renewal date. In the weeks before renewal, get quotes from at least 3 other insurers. Some companies are substantially more forgiving of a single accident than others. Switching before renewal locks in the better rate.
Ask about accident forgiveness before it applies
If your policy does not include accident forgiveness and you just had your first at-fault accident, call your insurer and ask whether it can be added retroactively - some will, some will not. It is worth asking.
Take a defensive driving course
Many insurers offer a 5-10% premium discount for completing an approved defensive driving course. In some states, it is mandatory for the insurer to offer the discount. The course takes 4-6 hours and costs $20-$50 - often worth far more than that in annual savings.
Raise your deductible temporarily
Switching from a $500 to a $1,000 deductible can offset 10-15% of the premium increase. This only makes sense if you have the cash reserve to cover the higher deductible if needed.
Do not file small claims
If you were involved in a minor fender-bender and the damage is close to your deductible, paying out of pocket avoids a claim on your record entirely - and avoids the 3-5 year surcharge that follows.
State-by-State: Rate Increase Limits
Some states restrict how much insurers can surcharge for an at-fault accident. Check your state's rules:
States with strong consumer protections:
- California: Cannot surcharge for not-at-fault accidents. Surcharge caps apply.
- Massachusetts: Uses a state-regulated surcharge schedule with defined caps per incident type.
- Hawaii: Rate increases are strictly regulated; insurers must justify surcharges.
States with less protection:
- Michigan: One of the highest average rate increases in the country after an accident.
- Louisiana, Florida: High base rates and significant surcharges for at-fault incidents.
- Most states allow insurers wide discretion in setting surcharge amounts.
Frequently Asked Questions
Will my insurance go up if the accident was not my fault?
In most cases, no - if the at-fault driver's insurance paid the claim and no claim was filed against your own policy, your rates should not increase. However, if you filed a claim under your own collision coverage (even for a not-at-fault crash), your insurer may count it. Always go through the at-fault driver's liability insurance when they are clearly at fault.
What happens to my insurance after a hit-and-run?
If a hit-and-run driver damaged your vehicle and you filed under your own uninsured motorist (UM) or collision coverage, it may show on your claims history. Most insurers treat hit-and-run claims similarly to not-at-fault claims and do not surcharge for them, but it depends on your insurer and state. Check your policy documents.
How soon after an accident does my rate go up?
The surcharge applies at your next policy renewal after the accident date - not immediately. If your policy renews in 8 months and the accident happened last week, your rate stays the same for 8 months. Then at renewal, the higher rate takes effect.
Does filing a claim always raise my rates?
No. Comprehensive claims (theft, weather damage, hitting a deer) typically do not trigger surcharges. Not-at-fault claims filed against the other driver's insurance do not go through your insurer at all. Rate increases are primarily triggered by at-fault accident claims filed under your own liability or collision coverage.
Key Takeaway
A single at-fault accident adds an average of $600 per year to your insurance bill for 3 to 5 years - totaling $1,800 to $3,000 in extra premiums. The best responses are: shop competing quotes before your renewal, ask about accident forgiveness, take a defensive driving course for a discount, and avoid filing small claims that sit close to your deductible. The insurer you had before an accident is not always the best option after one.
