This article is for general informational purposes and is not legal or insurance advice; figures reflect 2025 study data from LendingTree, Insurify, and ValuePenguin, and your actual rate will depend on your state, insurer, age, and driving history.
TL;DR — Quick Verdict
- A single DUI raises the average annual premium 74.5% nationally, from $2,130 to $3,716—an extra $1,585 a year, according to LendingTree.
- North Carolina drivers face the steepest hike at 284.1% ($1,208 to $4,640); Mississippi sees the smallest dollar increase at roughly $378 a year.
- Over a typical three-year high-risk period, the DUI adds about $4,755 to what you pay.
- An SR-22 filing itself costs only $15 to $50, but it flags you as high-risk and locks in the surcharge for about three years.
- Progressive vs. Nationwide: Progressive raised full-coverage rates by about $61 a month after a DUI versus $329 for Nationwide—so shopping three quotes is the single highest-value move you can make.
The financial penalty for a DUI dwarfs the fine printed on the citation. LendingTree’s 2025 analysis of insurance data found that a single conviction pushes the average annual full-coverage premium up 74.5%, climbing from $2,130 to $3,716. That $1,585 jump repeats every year the violation sits on your record—often three to five years, and up to a decade in California.
Insurers price DUIs as a predictor, not a punishment. Their loss data shows a convicted driver is statistically more likely to file a future claim, so the surcharge reflects expected risk. Carriers disagree sharply on how much risk that is: Progressive and Nationwide can quote the same driver rates hundreds of dollars apart per month, according to ValuePenguin.
This report breaks down the real cost of a DUI on your premium—the national and state-by-state numbers, what an SR-22 actually adds, how long the surcharge lasts, and which carriers punish a DUI least. Every figure traces to a named primary study, and the math is shown so you can apply it to your own situation.
What a DUI Actually Adds to Your Premium
Start with the headline number. LendingTree’s state-by-state study puts the national average post-DUI increase at 74.5%, lifting the typical full-coverage premium from $2,130 to $3,716 a year. That is the increase measured against the same driver’s clean-record rate, not a comparison between different people.
Other analysts land in a similar zone using different data sets, which is why you should read this as a range rather than a single point. Insurify’s review of quote data reports a national average closer to 44%, while insure.com pegs the typical increase at about 77%, or $1,163 in extra annual premium. ValuePenguin, measuring full-coverage policies specifically, found rates climb 88%—an added $183 per month. The spread comes from different coverage assumptions, driver profiles, and state weightings.

The practical takeaway: budget for a premium increase in the 45% to 90% range, then get real quotes—because the average conceals enormous state and carrier variation. Understanding your baseline first helps, so it is worth checking the average car insurance cost by state before you model the surcharge.
State-by-State: Where a DUI Costs the Most
Geography drives the biggest swings in what a DUI costs. The same conviction that adds a few hundred dollars in one state can more than triple a premium in another, because state law, litigation climate, and claim costs shape how insurers price risk.
North Carolina tops LendingTree’s ranking by a wide margin. A DUI there raises the average annual premium 284.1%, from $1,208 to $4,640—the largest percentage jump in the country. California ranks second at 136.0% ($2,600 to $6,135), and Delaware third at 124.0%. Measured in raw dollars, California and North Carolina hit hardest, adding roughly $3,535 and $3,432 a year respectively.

At the low end, the dollar impact is far gentler. Mississippi drivers see the smallest annual increase at about $378, followed by Maryland ($779) and Wyoming ($810). If you live in a high-impact state, the case for aggressive quote-shopping and for weighing your full coverage vs liability-only cost trade-offs gets much stronger, because trimming coverage may be the only near-term lever.
How Long the Surcharge Lasts—and How the Clock Works
A DUI is not a one-year penalty. Progressive notes that in many states a conviction stays on your driving record for seven to 10 years, and insurers weight it most heavily during the first three to five. FindLaw confirms most states hold the offense on your motor vehicle record for three to five years, while California keeps it for a full decade.
Consider a driver in a state with a three-year surcharge window and the national-average $1,585 annual increase. The math compounds fast: $1,585 across three years equals $4,755 in added premium—almost exactly the three-year figure LendingTree reports. Stretch that to California’s 10-year record with a $3,535 annual bump and the lifetime cost of one conviction can exceed $30,000 before any fines, legal fees, or license-reinstatement charges.
The surcharge also fades gradually rather than vanishing on an anniversary. Florida-based analyses describe rate reductions of roughly 10% to 25% per year once you clear the mandatory SR-22 period, provided you avoid new violations. Because a DUI is treated more severely than a fender-bender, the recovery curve is longer than what you would see with premium increases after an accident and duration, where surcharges typically resolve inside three to five years.
The SR-22 Requirement and What It Adds
Most states require a DUI driver to file an SR-22 before a license is reinstated. Despite the intimidating name, an SR-22 is not insurance—it is a one-page certificate your insurer files with the state proving you carry at least the minimum liability coverage. The filing fee itself is trivial: $15 to $50 as a one-time charge, according to multiple insurer and legal sources.
The expense is what the SR-22 represents, not the form. Filing one formally labels you high-risk, and that classification—typically lasting three years from conviction or license reinstatement—is what keeps your premium elevated. Insurance.com data cited by industry guides puts the average extra cost of carrying SR-22-tied coverage near $993 a year on top of the base rate, driven by the surcharge rather than the paperwork.
One rule matters above all others: continuous coverage. If your policy lapses during the SR-22 period, the insurer must notify the state, which can suspend your license and reset the three-year clock to zero. The full breakdown of SR-22 insurance costs, requirements, and duration is worth reading before you choose a payment plan, since a single missed installment can restart the entire requirement.
Progressive vs. Nationwide: Which Is Better After a DUI?
Carrier choice is the biggest variable you control, and the gap between insurers dwarfs most other savings levers. ValuePenguin’s 2026 analysis found that after a single DUI, Progressive raised full-coverage rates by an average of just $61 a month, while Nationwide raised them by $329 a month—a $326 monthly difference, or nearly $3,900 a year, for the same driver.
Progressive’s appeal is twofold: a smaller DUI surcharge and in-house SR-22 filing, so you avoid hunting for a separate high-risk carrier. Nationwide may still make sense if a driver already bundles home and auto there and the multi-policy discount offsets part of the surcharge, but on the DUI line item alone it prices near the top of the major carriers.
The comparison also shows why loyalty is expensive after a conviction. Standard carriers that were competitive on a clean record can become the most punitive after a DUI, so the pre-DUI ranking in any list of car insurance company claims ratings and prices tells you little about post-DUI pricing.
Verdict
For most drivers focused purely on the DUI surcharge, Progressive is the stronger default—roughly $268 a month cheaper than Nationwide on full coverage after a conviction, with SR-22 filing built in. Nationwide only wins when an existing multi-policy bundle discount is large enough to close a nearly $3,900 annual gap, which is rare. Either way, pull quotes from at least three insurers, because a nonstandard carrier like The General may undercut both.
What Most People Get Wrong After a DUI
Three mistakes cost DUI drivers thousands in avoidable premium, and each has a clear fix.
Mistake 1: Renewing with the same insurer on autopilot. The consequence is paying a top-quartile surcharge when a competitor would charge less than half. The correct action is to compare at least three quotes—including nonstandard carriers—within the first renewal cycle, since the $326-per-month Progressive-to-Nationwide gap shows how wide pricing runs.
Mistake 2: Letting coverage lapse to save money short-term. The consequence is severe: a lapse during the SR-22 window triggers state notification, possible license suspension, and a reset of the three-year clock. The correct action is to keep coverage continuous even if it means switching to a cheaper high-risk carrier rather than going uninsured for a month.
Mistake 3: Assuming credit and other factors are frozen. A DUI stacks on top of every other rating factor, so a credit drop during the same period compounds the surcharge. Because credit score impact on car insurance rates is significant in most states, protecting your credit while the DUI ages off keeps the total bill lower.
Is It Worth Trying to Lower Your Rate? Conditional Logic
Whether active rate-reduction effort pays off depends on your state and record. If you live in a high-impact state like North Carolina or California, where the surcharge runs into thousands per year, the answer is unambiguous: the potential savings from shopping and coverage adjustments are large enough to justify serious effort.
If you are in a low-impact state where the DUI adds only $378 to $810 a year, the calculus shifts. Aggressively cutting coverage to save a few hundred dollars may expose you to far larger out-of-pocket risk in a crash, so maintaining protection often beats chasing the discount. In that case, low-effort moves—confirming existing discounts, choosing a higher deductible—capture most of the available savings.
Across every state, a few levers apply. Raising your deductible, completing a state-approved defensive driving course, and comparing quotes annually as the DUI ages all help. Usage-based programs are a mixed bet for high-risk drivers; weigh the usage-based insurance savings vs privacy trade-offs before enrolling. For a structured checklist, the verified strategies to lower car insurance premiums apply directly once the mandatory SR-22 period ends and more carriers reopen to you.
Frequently Asked Questions
How much does a DUI raise car insurance on average?
LendingTree’s 2025 study found a single DUI raises the average annual full-coverage premium 74.5%, from $2,130 to $3,716—an added $1,585 a year. Estimates vary by source and coverage type, ranging from about 44% (Insurify) to 88% (ValuePenguin). Your actual increase depends heavily on your state, with North Carolina drivers seeing hikes above 280%.
How long does a DUI affect my insurance rates?
In most states a DUI stays on your driving record three to five years, though California keeps it for 10, according to FindLaw. Progressive notes it can remain seven to 10 years in many states. Insurers weight it most heavily during the first three years, then typically reduce rates 10% to 25% annually once the SR-22 period ends and you avoid new violations.
How much does an SR-22 cost?
The SR-22 filing fee is a one-time charge of $15 to $50, per multiple insurer and legal sources. The real cost is the high-risk classification it represents, which Insurance.com data links to roughly $993 in extra annual premium. Most states require the SR-22 for about three years, and any coverage lapse can reset that clock.
Which insurer is cheapest after a DUI?
Among major carriers, ValuePenguin’s 2026 data shows Progressive raised full-coverage rates by about $61 a month after a DUI versus $329 for Nationwide—a $326 monthly gap. Nonstandard insurers like The General also compete for high-risk drivers. Because pricing varies so widely, comparing at least three quotes is the most reliable way to find the lowest rate.
How We Researched This Article
This report synthesizes 2025 and early-2026 data from four primary and secondary insurance research sources, prioritizing studies that disclose their methodology and sample size. The national and state-by-state percentage increases come from the LendingTree DUI Rates Study, which compared average full-coverage premiums for the same driver profile before and after a single DUI across U.S. states. We cross-checked LendingTree’s national figure against three independent analyses to establish a defensible range rather than a single point estimate.
Carrier-level comparisons (Progressive versus Nationwide) are drawn from ValuePenguin’s 2026 DUI rate analysis. Additional national-average context comes from Insurify’s quote-based study and the LendingTree DUI Rates Study. SR-22 requirements and record-duration figures were verified against Progressive’s DUI insurance guidance and FindLaw’s DUI and insurance overview.
Percentage increases are modeled from study averages, not measured from any individual policy; your quote will differ based on state, insurer, age, credit, and prior record. Where sources reported different national averages, we present the range and explain the variance rather than selecting one figure. Multi-year cost projections are simple compounding calculations using each study’s stated annual increase and typical surcharge duration; they illustrate scale and are not guarantees. This research was last conducted in July 2026. All figures were verified against named primary sources before publication.
