If a ticket, an at-fault accident or a DUI has pushed you into high-risk pricing, the size of the increase depends far more on which insurer wrote your policy than on any national average. Published rate studies put the post-accident surcharge as low as 14% at State Farm and as high as 82% at GEICO for their respective test profiles (ValuePenguin, 2026-07-17; Insurance.com (QuinStreet), 2026-09-25), on top of starting premiums that already differ sharply: NerdWallet's 2025-09 analysis puts clean-record full coverage at $3,210 a year for Allstate and $1,587 for USAA.
These are modeled estimates for specific sample drivers, not quotes for you. Where you live, what limits you buy, and whether your state is a no-fault or at-fault/tort state change the arithmetic, and only a bound policy tells you your actual price.
How These Rates Were Compared
The numbers below come from published rate studies, each built on a different sample driver. They are modeled estimates generated from insurer rate filings and quoting engines, not premiums anyone actually paid, and they are not quotes you can hold an insurer to.
- Insurance.com (QuinStreet), 2026-09-25. A 40-year-old driver with a clean record, good credit, a Honda Accord LX, a 12-mile commute and 10,000 annual miles, carrying 100/300/100 liability with $500 comprehensive and collision deductibles. Additional pulls cover the same driver with one at-fault accident and an 18-year-old driver.
- ValuePenguin, 2026-07-17. A 30-year-old man with good credit and a 2018 Honda Civic EX, carrying 50/100/50 bodily injury and property damage limits with a $500 comprehensive/collision deductible. The accident-surcharge quotes were compiled using Quadrant Information Services data sourced from public insurance company filings.
- NerdWallet, 2025-09. Median estimates for 35-year-old male and female drivers with good credit and no tickets or violations, carrying $100,000/$300,000 bodily injury liability, $100,000 property damage liability, $100,000/$300,000 uninsured motorist bodily injury and $1,000 collision/comprehensive deductibles, generated through Quadrant Information Services. NerdWallet states plainly that your own rates will be different.
- AutoInsurance.com, 2026-08-13, CarInsurance.com (undated) and LendingTree (undated) supply the remaining carrier-level and violation-level figures, each attributed inline where it appears below.
Those profiles are not interchangeable. The ValuePenguin figures sit on lower 50/100/50 liability limits, and the NerdWallet figures use a $1,000 deductible rather than $500 — both choices move the premium before any surcharge is applied. When you compare a carrier's 14% increase in one study (ValuePenguin, 2026-07-17) with another's 82% in a second (Insurance.com (QuinStreet), 2026-09-25), you are comparing two different sample drivers in two different limit structures, which is why the table below keeps the source attached to each row.
None of these datasets models a license suspension or an SR-22/FR-44 filing at the carrier level, and requirements for those filings are set state by state.
Rate Comparison
Average annual full-coverage premiums before and after one at-fault accident, for the sample profiles described above:
| Insurer | Clean record | After one at-fault accident | Published change | Sample profile |
|---|---|---|---|---|
| USAA (eligibility limited to military and family) | $1,381 | $2,091 | cheapest average both before and after an accident in this data set | 40-year-old, 100/300/100, $500 ded. (Insurance.com (QuinStreet), 2026-09-25) |
| GEICO | $1,763 | $3,207 | +82%, the largest average increase among the majors tested | 40-year-old, 100/300/100, $500 ded. (Insurance.com (QuinStreet), 2026-09-25) |
| Allstate | $2,509 | $4,149 | not published as a percentage in this data set | 40-year-old, 100/300/100, $500 ded. (Insurance.com (QuinStreet), 2026-09-25) |
| State Farm | not published | not published | +23%, the smallest increase among carriers open to all drivers | 40-year-old, 100/300/100, $500 ded. (Insurance.com (QuinStreet), 2026-09-25) |
| State Farm | not published | $218/month | +14%, smallest among majors tested | 30-year-old man, 50/100/50, $500 ded. (ValuePenguin, 2026-07-17) |
| Farmers | $3,023 | $5,015 | +66% | AutoInsurance.com, 2026-08-13 |
| Erie | $1,833 | $2,265 | +23% | AutoInsurance.com, 2026-08-13 |
| Auto-Owners | $1,870 | $2,246 | +20% | AutoInsurance.com, 2026-08-13 |
Starting points differ before any violation is added. On clean-record full coverage, NerdWallet's 2025-09 analysis lists average annual premiums of $3,210 for Allstate, $2,020 for GEICO, $1,985 for State Farm, $1,652 for Travelers and $1,587 for USAA for the same 35-year-old sample driver on $100,000/$300,000 limits and $1,000 deductibles.
Violation type matters as much as carrier. Against a $2,361 clean-record full-coverage average, NerdWallet (2025-09) puts a recent speeding ticket at $3,028 (+28%), one at-fault accident at $3,524 (+49%) and a recent DUI at $4,437 (+88%, about $2,076 more a year). CarInsurance.com (undated) models higher figures for injury claims: an at-fault bodily injury accident takes a $2,578 base rate to $4,238 (+64%), and two at-fault property damage accidents over $2,000 each to $6,075 (+136%). Insurance.com (QuinStreet), 2026-09-25, puts the nationwide post-accident increase at $1,551 a year on 100/300/100 full coverage with $500 deductibles.
State differences can exceed insurer differences. Louisiana's average full-coverage rate after an accident is $4,279, up from $2,883 with a clean record, while Maine's is $1,732, up from $1,175 (Insurance.com (QuinStreet), 2026-09-25). In monthly terms after an accident, ValuePenguin (2026-07-17) quotes $437 in California (a 98% increase) and $507 in Connecticut (a 66% increase) for its 30-year-old 50/100/50 profile.
Where the Price Difference Comes From
- Different surcharge schedules filed for the same event. Each insurer files its own accident and violation surcharge with each state regulator. That is the mechanical reason one carrier's increase for a single at-fault accident lands at 23% and another's at 82% on the same 40-year-old, 100/300/100 profile (Insurance.com (QuinStreet), 2026-09-25) — not a judgment about which brand is friendlier.
- Different base rates before any surcharge. A smaller percentage on a higher base can still cost more. Farmers' 66% increase applies to a $3,023 clean-record premium and lands at $5,015, while Erie's 23% applies to $1,833 and lands at $2,265 (AutoInsurance.com, 2026-08-13).
- Territory rating and state loss experience. Carriers divide each state into rating territories and price to claims experience, litigation costs and repair costs there. That shows up as Louisiana's $4,279 post-accident average against Maine's $1,732 (Insurance.com (QuinStreet), 2026-09-25) and as the 98% post-accident increase quoted in California versus 66% in Connecticut (ValuePenguin, 2026-07-17).
- Eligibility restrictions that shape the risk pool. USAA's $1,381-to-$2,091 figures (Insurance.com (QuinStreet), 2026-09-25) come from a membership-restricted book limited to military members and their families; a carrier that must accept all applicants prices a broader mix of risk.
- Different weight on credit-based insurance score. Every one of these studies assumes good credit (Insurance.com (QuinStreet), 2026-09-25; ValuePenguin, 2026-07-17; NerdWallet, 2025-09). Carriers weight credit-based insurance scores differently in their filings, and several states restrict or prohibit the practice outright, so a profile with weaker credit can reshuffle the ranking entirely in some states and not at all in others.
- Different discount structures. Bundling is filed as a discount percentage that varies by company: State Farm averages 22%, Farmers 19%, and Nationwide and Allstate 17%, against an average home-and-auto saving of 15%, or just over $869 a year (Insurance.com (QuinStreet), undated). A high surcharge partly offset by a large bundle discount can beat a low surcharge with no discount available.
- Different limits and deductibles in the comparison itself. ValuePenguin's 50/100/50 with a $500 deductible (2026-07-17) and NerdWallet's $100,000/$300,000 limits with a $1,000 deductible (2025-09) are not the same product. Raising a deductible or lowering liability limits changes the premium independently of your record — and carrying only state-minimum liability leaves you exposed to anything above those limits.
Which Driver Profile Fits Which Insurer
One recent at-fault accident, clean otherwise, no military eligibility. State Farm is where the published surcharge data is most favorable: the smallest increase among carriers open to all drivers at 23% on the 40-year-old 100/300/100 profile (Insurance.com (QuinStreet), 2026-09-25) and 14% at an average $218 a month on the 30-year-old 50/100/50 profile (ValuePenguin, 2026-07-17). Where they write, the regional carriers test similarly: Erie at +23% ($1,833 to $2,265) and Auto-Owners at +20% ($1,870 to $2,246), per AutoInsurance.com, 2026-08-13. The same data makes GEICO the one to re-quote against, given its 82% average increase ($1,763 to $3,207).
Military-affiliated drivers. USAA posted the cheapest averages both before and after an accident, at $1,381 clean and $2,091 after one at-fault accident on the 40-year-old 100/300/100 profile (Insurance.com (QuinStreet), 2026-09-25), and $1,587 for clean-record full coverage in NerdWallet's 2025-09 analysis. If you are eligible, that is worth a quote before you accept a surcharged renewal elsewhere — but eligibility, not price alone, decides whether it is open to you.
Teen or young drivers with an accident on record. LendingTree's teen-driver post-accident table (undated) puts Erie at $137, Country Financial at $169 and State Farm at $193 — so the regional carriers, where licensed in your state, are the ones to check first alongside State Farm.
Driver with a recent DUI. None of these carrier-level tables models a DUI. What the data does show is the scale: full coverage rising from $2,361 with a clean record to $4,437 after a recent DUI, an 88% increase worth about $2,076 a year (NerdWallet, 2025-09). Expect eligibility, not just price, to drive the outcome, and expect any required state filing to be handled on your state's terms.
Homeowner carrying a surcharge. If you own the home you insure, the bundle discount can partly offset the surcharge — 22% at State Farm, 19% at Farmers, 17% at Nationwide and Allstate (Insurance.com (QuinStreet), undated) — which is the one lever that changes the ranking for an Allstate or Farmers customer whose post-accident premium otherwise lands at $4,149 (Insurance.com (QuinStreet), 2026-09-25) or $5,015 a year (AutoInsurance.com, 2026-08-13).
In every case, get at least three quotes at identical limits and deductibles, and re-shop at each renewal while the surcharge is on your record. Drivers pay higher rates for an average of three years after an accident (LendingTree, undated), though the period the violation stays on your motor vehicle record is set separately by your state and can be longer than the period it affects pricing.
Questions
Does this comparison hold if I have a teen driver on the policy?
No — the ranking shifts. For teen drivers with an accident, LendingTree's table (undated) puts Erie at $137, Country Financial at $169 and State Farm at $193, so regional carriers lead where they are licensed. The main studies here model a 40-year-old, a 35-year-old and a 30-year-old (Insurance.com (QuinStreet), 2026-09-25; NerdWallet, 2025-09; ValuePenguin, 2026-07-17); only the Insurance.com dataset also pulls an 18-year-old. Adding a teen is a separate rating change from your surcharge, so re-quote the whole household rather than assume the adult-driver spread applies.
Does bundling home and auto change which insurer is cheapest for me?
It can. Bundle discounts are filed separately by each carrier: State Farm averages 22%, Farmers 19%, and Nationwide and Allstate 17%, with an average home-and-auto saving of 15%, or just over $869 a year (Insurance.com (QuinStreet), undated). Applied to Farmers' $5,015 post-accident average (AutoInsurance.com, 2026-08-13), a 19% auto discount narrows but does not close the gap to Erie's $2,265 in the same data set. Ask each insurer to quote the bundle and the standalone auto policy so you can see the discount rather than infer it.
How long will the surcharge stay on my premium?
Drivers pay higher rates for an average of three years after an accident (LendingTree, undated). That pricing period is not the same as how long the incident stays on your motor vehicle record, which each state sets separately and which can run longer. Ask your insurer which rating period applies to your specific surcharge, and re-shop at least once a year while it is in force — the 82% average post-accident increase at GEICO versus 23% at State Farm on the same 100/300/100 profile (Insurance.com (QuinStreet), 2026-09-25) is exactly the kind of gap that only shows up if you re-quote.
I got a speeding ticket, not an accident — do these numbers apply?
Only loosely. A recent speeding ticket raised NerdWallet's 2025-09 full-coverage average from $2,361 to $3,028, a 28% increase, against 49% for one at-fault accident and 88% for a recent DUI in the same analysis. The carrier-level tables above were built on an at-fault accident, so a carrier that surcharges accidents lightly may not surcharge moving violations the same way. Severity matters too: CarInsurance.com (undated) models two at-fault property damage accidents over $2,000 at $6,075, a 136% increase on a $2,578 base rate.
