How Much Car Insurance Goes Up After a DUI
Typical premium increases after a DUI, why the range is so wide, and how to tell whether your renewal quote is in the normal band.

Answer in brief
Nationally, a DUI conviction typically raises car insurance premiums by 60–100%, and in some states the increase exceeds 150%. The range is wide because each insurer weights the conviction differently, states set different rules on how long it can be used, and your other rating factors (age, record, vehicle, coverage) still apply. If your renewal arrived at double the old price, it is in the normal band—but it is also the moment when comparing other providers pays off most.
Why a DUI is weighted so heavily
Insurers set premiums from the probability and likely cost of future claims. Among everything on a driving record, an impaired-driving conviction is one of the strongest predictors of a serious future loss. Highway-safety research consistently shows that alcohol-impaired drivers are over-represented in fatal crashes, and fatal and severe-injury crashes are the most expensive claims an insurer pays. A DUI therefore moves a driver from the standard or preferred rating tier into the high-risk (sometimes called non-standard) tier, where base rates are substantially higher before any other factor is applied.
Two mechanisms produce the increase you see. The first is a surcharge: a percentage added to your premium for a specific violation, usually for three years. The second is re-tiering: being moved to a different rate class or to a different company within the same group that writes higher-risk business. Many drivers experience both at once at the first renewal after the conviction appears on their record.
What the increase typically looks like
Published rate analyses that compare a clean-record driver with the same driver plus a single DUI generally find national average increases in the 60–100% range. The state you live in is the biggest reason your number may differ from the average:
| State pattern | Typical DUI impact | Why |
|---|---|---|
| High-impact states (e.g. parts of the West and Southeast) | +120% to +180% | Long lookback windows, FR-44-style higher limits, or strict good-driver rules |
| Mid-range states | +70% to +110% | Standard 3–5 year surcharge periods |
| Lower-impact states | +40% to +70% | Shorter surcharge periods or rate-filing rules that cap violation surcharges |
Your own factors stack on top. A 22-year-old with a DUI faces a larger dollar increase than a 45-year-old with the same conviction because the base rate for young drivers is already higher. A driver who also has a recent at-fault accident or a lapse in coverage will see the effects compound.
When the increase shows up
Most insurers re-check driving records at renewal rather than mid-term, so the increase usually appears on the first renewal notice after the conviction is recorded. If you are required to file an SR-22 or FR-44, however, the insurer learns about the conviction immediately when you request the filing, and may re-rate the policy at that point. Some policies also allow mid-term changes when a filing is added.
How long the higher price lasts
Surcharges typically run for three years from the conviction date, and most insurers stop rating the DUI after three to five years. A few states, notably California, require the conviction to count against good-driver discount eligibility for ten years. The how long a DUI affects insurance guide covers the windows in detail and explains why the price often steps down rather than dropping all at once.

What to do with the number
A high renewal quote is a reason to shop, not a reason to go uninsured. Driving without coverage after a DUI usually means a second, longer licence suspension and a reset of your filing period. The most effective single action is to compare quotes from several providers: because companies weight a DUI differently, the gap between the highest and lowest quote for the same driver is wider after a conviction than at any other time. After that, the lowering rates guide covers the levers you control.

Questions & answers
Will my insurance go up immediately after a DUI arrest?
Usually not at arrest. Insurers act on convictions that appear on your driving record, typically at renewal, or when you request an SR-22/FR-44 filing.
Does the increase depend on my blood alcohol level?
Generally no. Most insurers rate a DUI conviction as a single violation category regardless of BAC, though an aggravated or felony DUI may be treated more severely.
Can my insurer raise my rate mid-policy because of a DUI?
In many states the premium is locked for the policy term unless you make a change. Adding a filing counts as a change and can trigger re-rating. Check your policy's mid-term adjustment language.
Terms used in this guide
- Surcharge
- A percentage added to a premium for a specific violation or accident, applied for a set period—commonly three years for a DUI.
- High-risk driver
- An insurer's classification for a driver whose record—typically a DUI, multiple violations, at-fault accidents or a coverage lapse—predicts above-average claim costs. High-risk drivers are rated in a higher tier or placed with non-standard insurers.
- Non-standard insurance
- The segment of the auto insurance market that specialises in drivers standard insurers decline or price steeply, including drivers with a DUI. Non-standard insurers routinely provide SR-22 filings.
- Lookback period
- How many years into your driving record an insurer looks when rating you. Three and five years are common; the conviction stops affecting your premium once it is outside the period.
