DUI Laws by State 2026

Arizona will jail you for 10 days on a first DUI. Wisconsin treats the same conduct as a civil ticket. Same federal 0.08% per se threshold, opposite outcome.

Every state has implied consent. Every state suspends your license on conviction. Past those two facts, the actual cost of a DUI varies by an order of magnitude depending on your zip code.

Oregon's max fine is over 60 times West Virginia's. Mandatory jail in 5 states. Where you get arrested ends up mattering more than the BAC number itself.

This page maps every state's first-offense penalties side by side and explains how the rules escalate when a second offense, a child in the car, or a 0.15+ BAC enters the picture. Use our BAC calculator to estimate your level before driving, the DUI penalty calculator for a 15-state interactive lookup, and the legal BAC limits page for the underlying threshold rules.

The 0.08% Standard and Its Exceptions

The 0.08% per se BAC threshold is the federal-pressure floor. The Department of Transportation Appropriations Act of 2000 conditioned highway funding on adoption, and by October 2004 every state and DC had complied. Utah went further in December 2018 and dropped to 0.05%. NHTSA's February 2022 evaluation found Utah's fatal crash rate fell 19.8% in the first full year after the change, but no other state has followed despite NTSB recommendations.

Two BAC thresholds run alongside the 0.08% adult standard in every state:

• Commercial drivers (CDL): 0.04% — half the standard threshold, set federally by FMCSA, applies in all 50 states. A single conviction triggers a one-year CDL disqualification; a second is permanent.
• Drivers under 21: zero tolerance — 0.00%, 0.01%, or 0.02% depending on the state. California and New Jersey use 0.01%. Illinois, Maine, Minnesota, North Carolina, Oklahoma, Oregon, and Texas use a hard 0.00%.

A third threshold matters for sentencing — the high-BAC enhancement, often called "aggravated" or "extreme" DUI. Most states draw it at 0.15%, a few at 0.16%, New Jersey unusually low at 0.10%, and Idaho, Massachusetts, and Tennessee at 0.20%. Cross that threshold and minimum jail time, longer suspensions, mandatory interlock, and felony charges in some jurisdictions all become possible on a first offense.

Visualizing How States Differ

DUI Penalties by State — First Offense

The table below covers all 50 states. Numbers reflect first-offense, no-aggravating-factor cases — meaning no child in the vehicle, no injury, no prior convictions in the lookback window, BAC under 0.15%. Add any of those and the penalties escalate sharply, sometimes into felony territory. Court costs, surcharges, attorney fees, and insurance impact all sit on top of the base statutory range.

DUI vs DWI vs OWI vs OUI: Why the Acronym Soup

Every state criminalizes the same conduct — operating a motor vehicle with a BAC at or above 0.08% (or 0.05% in Utah). The difference is the label the legislature picked when it codified the offense. None of the labels carry different penalties on their own.

• DUI (Driving Under the Influence): the most common term, used in 30+ states including California, Florida, Pennsylvania, Arizona, Colorado, and Virginia.
• DWI (Driving While Intoxicated): used in Texas, New York, New Jersey, Missouri, Louisiana, Arkansas, Minnesota, and a handful of others. In Texas specifically, DWI is the adult charge while DUI is reserved for under-21 drivers with any detectable alcohol.
• OWI (Operating While Intoxicated): Wisconsin, Indiana, Michigan, and Iowa. The "operating" framing extends the offense to vehicles that are not technically being driven — a stationary car with the engine running has been enough for an OWI conviction in Wisconsin.
• OUI (Operating Under the Influence): Maine and Massachusetts. Legally identical to DUI for sentencing purposes.
• OVI (Operating a Vehicle Impaired): Ohio's specific term, encompassing alcohol, drugs, or any combination.
• DUII (Driving Under the Influence of Intoxicants): Oregon's variant, explicitly broad enough to cover both alcohol and controlled substances under one statute.
• DWUI: Wyoming's hybrid term — Driving While Under the Influence.

MADD treats DUI and DWI as the same offense in its public education materials. The Driver License Compact does too.

A New York DWI lands in California as a DUI for suspension purposes. A California DUI lands in Texas as a DWI. The labels never change the outcome — your record follows you across state lines either way.

How Penalties Escalate: 1st → 2nd → 3rd Offense

The single biggest factor in DUI sentencing after BAC is your prior history within the lookback window. The pattern is consistent across states: each subsequent offense adds mandatory jail, longer license suspension, longer interlock, higher fines, and at some point flips the misdemeanor into a felony.

Second Offense

The second-offense jump is steep. Most states impose mandatory minimum jail of 5–30 days, fines that double or triple the first-offense range, and license suspension that stretches to 1–2 years. Ignition interlock becomes mandatory in nearly every state for the second offense if it was not already required for the first. Insurance impact compounds — many insurers refuse to renew, forcing the driver into the high-risk pool with premiums often 200–400% above standard.

Third Offense and Felony Threshold

Roughly 45 states upgrade a third DUI within the lookback window to a felony.

California sits at the lenient end of this — the state needs four DUIs within a 10-year window before bumping the charge to felony. Wisconsin holds most repeat OWIs in misdemeanor territory through the third.

In the other 45 states, third-offense DUI means 1–7 years of prison, near-permanent license revocation, mandatory long-term interlock on reinstatement, and the loss of voting and firearm rights that follows any felony conviction.

Aggravating Factors That Upgrade a First Offense

A clean first offense — adult driver, BAC under 0.15%, no kids in the car, no crash, no injury — is the baseline reflected in the table above. The moment any aggravating factor enters the picture, the misdemeanor framework can collapse and felony charges become possible.

Child in the Vehicle

About 10 states elevate a first DUI with a minor passenger straight to felony status. The threshold age varies — California uses under 14, Texas under 15, Tennessee under 18. In states that do not auto-upgrade to felony, child endangerment is typically charged as a separate offense on top of the DUI, with its own jail and fine ranges. Florida's "Trenton's Law," which took effect in 2025, made enhanced penalties mandatory in any DUI case involving a minor passenger.

Serious Injury or Death

All 50 states classify a DUI causing serious bodily injury as a felony, regardless of prior record. Sentencing typically runs 2–15 years per count. A DUI causing death is charged as vehicular homicide, vehicular manslaughter, or DUI manslaughter depending on the state — the typical sentence is 5–25 years, and some states allow second-degree murder charges if prior DUI convictions establish willful disregard for human life. Watson murder doctrine in California is the most well-known of these enhanced theories.

High BAC

The 0.15% high-BAC tier triggers in most states. New Jersey draws the line lower at 0.10%. Idaho, Massachusetts, and Tennessee draw it higher at 0.20%. Arizona's "extreme DUI" at 0.15% adds 30 days of un-suspendable jail to a first offense; its "super extreme" tier at 0.20% pushes the mandatory minimum to 45 days. The general rule: every 0.05% increment above the per se limit makes the conviction harder to plea down and the suspension harder to negotiate.

Implied Consent: What Happens When You Refuse

Every state except Wyoming treats breathalyzer or blood-test refusal as a separate offense from the DUI itself. The reasoning is straightforward — by accepting a driver's license you have already consented in advance to chemical testing if lawfully arrested for impaired driving. Refuse, and the implied consent statute kicks in independently of the criminal case.

The standard penalty is automatic license suspension, often 6 months to 1 year for a first refusal, sometimes 18 months or longer in repeat-refusal states. Many states stack a separate fine on top — New York charges $500 for a refusal plus $350 in administrative fees. Crucially, the refusal suspension runs independently of any suspension that follows a DUI conviction, and prosecutors in most states can introduce the refusal as evidence of consciousness of guilt at trial.

The math on whether to refuse rarely favors the driver. The prosecutor loses a hard BAC number, which can help in close cases, but the driver loses their license either way and faces a longer suspension for refusing than for failing. The exception is when a driver knows their BAC is well above 0.15% and the high-BAC enhancement would trigger — refusing avoids the enhancement at the cost of a longer baseline suspension. That trade-off requires legal advice in the moment, which is why getting an attorney on the phone before deciding matters more than any general rule.

Administrative License Suspension (ALS)

Forty-four states and DC have administrative per se laws — meaning the state DMV can suspend your license before any criminal court touches the case. ALS triggers automatically within 7–30 days of arrest based on the breathalyzer reading or refusal alone, separate from the DUI charge.

The hearing window is short and unforgiving. Texas gives 15 days, Georgia 30 days, California 10 business days. Miss the deadline and the suspension stands automatically — no court can restore the license until the administrative period runs. Winning the hearing only restores driving privileges; the criminal DUI case continues separately and can produce its own suspension if you are convicted later.

Ignition Interlock: Where, When, and How Long

The IIHS list as of September 2024 shows that 43 states require ignition interlock for all DUI offenders, including first-time. The seven exceptions — Indiana, Montana, Nevada, North Dakota, Rhode Island, South Dakota, and Wisconsin — only mandate interlock for high-BAC offenders (typically 0.15% or higher) or for repeat offenders. Florida and Michigan trigger first-offense interlock at the high-BAC threshold rather than for every conviction.

IIHS research found that all-offender interlock laws cut alcohol-impaired fatal crashes by roughly 26% compared to no interlock law. Laws covering only repeat offenders cut the rate by 3%. Laws covering both repeat and high-BAC offenders cut it by 8%. The all-offender approach is roughly three times more effective than the targeted approach, which is why MADD, NTSB, and NHTSA all push for universal first-offender interlock.

The cost falls on the driver. Installation runs $100–$300, monthly monitoring fees $60–$100, removal $50–$150. A typical 1-year interlock requirement costs $900–$1,500 out of pocket, and a 2-year requirement runs $1,500–$2,500. The interlock period typically begins after the hard suspension ends, and many states require violation-free completion before the device can be removed — meaning a single failed test can extend the interlock by 6 months to 1 year.

The True Cost of a DUI

NHTSA pegs the all-in cost of a first-offense DUI at around $10,000 in fines and legal fees. Defense attorneys and DUI insurance estimators consistently put the realistic total at $10,000–$25,000 once insurance impact is included over 3–5 years. Our DUI penalty calculator walks through state-specific penalty ranges, but the real damage is the layered ongoing cost.

The bills break down roughly like this for a first offense with no aggravating factors:

• Court fine: $200–$2,500 — set by the statute and the judge, not negotiable in most states.
• Court costs and surcharges: $500–$1,500 — administrative fees, victim compensation funds, lab fees.
• Defense attorney: $1,500–$5,000 for a guilty plea or simple case, $5,000–$15,000 if it goes to trial.
• Ignition interlock (1–2 years): $900–$2,500 for installation, monthly monitoring, and removal.
• DUI education / treatment program: $300–$1,000 for the standard 12–24-hour program, $500–$5,000 if treatment is ordered.
• License reinstatement fee: $50–$500 depending on state.
• SR-22 insurance filing: $25 filing fee per state, but the underlying high-risk policy typically adds $1,000–$2,000 per year for 3 years (Texas requires 2 years, most states require 3, some up to 5).
• Insurance increase (3–5 years): the average 74% premium hike works out to roughly $1,500/year for most drivers, totaling $4,500–$7,500 across the surcharge period.
• Lost wages: court appearances, mandatory classes, and the suspension itself typically cost $1,000–$5,000 in missed work.

That math puts the true first-offense total in the $10,000–$25,000 range that NHTSA and defense attorneys both cite. Compare it to the $15–$30 cost of a rideshare home and the prevention math is not subtle — a single avoided DUI pays for hundreds of cab rides.

Diversion Programs and Deferred Adjudication

Some states allow first-time, low-BAC offenders to enter a diversion program in exchange for dismissal of the DUI charge after successful completion. The list rotates as legislatures change their minds, but as of 2026 the states that offer some form of DUI diversion or deferred adjudication include Florida, Georgia, Indiana, Kansas, Louisiana, Oregon, Pennsylvania, and Texas. California, Kentucky, and Tennessee are notable for explicitly prohibiting DUI diversion.

Eligibility is narrow. Most diversion programs require a BAC under 0.15%, no prior DUI convictions, no accident, no injury, and no minor in the vehicle. The program itself typically demands DUI school, alcohol treatment evaluation, regular drug testing, community service, and a year or two of supervised probation. Successful completion gets the charge dismissed — meaning no DUI conviction on the criminal record. Failure means the original guilty plea is entered and full sentencing follows.

Pennsylvania's ARD and Oregon's DUII Diversion both run about a year of monitoring, treatment, and abstinence with charge dismissal at the end. Both require waiving constitutional rights up front, including the right to challenge evidence — which is why an attorney has to vet the math before any opt-in.

Drugged Driving (DUID) and Cannabis

Every state has DUID laws on the books. They fall into three categories: effect-based laws (prosecution must prove actual impairment), per se laws (a fixed nanogram threshold of THC or other substance triggers conviction regardless of impairment), and zero-tolerance laws (any detectable amount triggers conviction).

Eleven zero-tolerance states cover one or more drugs including cannabis: Arizona, Delaware, Georgia, Indiana, Iowa, Michigan, Oklahoma, Rhode Island, South Dakota, Utah, and Wisconsin. Six states use per se THC limits ranging from 1 to 5 ng/mL: Illinois, Ohio, Pennsylvania, Montana, Nevada, and Washington. Colorado uses a 5 ng/mL "permissible inference" rather than a strict per se rule, meaning the prosecution can argue impairment if THC is at or above 5 ng/mL but the defense can rebut.

The pharmacology problem is real. THC is fat-soluble and metabolites linger in regular cannabis users for days after use, long after psychoactive effects have ended. A 2025 study of regular consumers found many exceed per se cutpoints days after their last use, which means the legal risk in zero-tolerance and low-threshold states extends well beyond actual impairment. This is one of the active fronts in DUID law and likely to keep changing as more states legalize cannabis.

Lookback Periods: How Long Priors Count

The lookback period (also called the washout period) determines how far back prior DUIs are counted for sentencing. A 5-year lookback means a DUI from 6 years ago is treated as if it never happened for the purposes of charging your next offense as a first or second.

• 5 years: Alabama, Florida (for second offense — extends to 10 for third).
• 7 years: Arizona, Michigan, North Carolina.
• 10 years: California, Colorado, Georgia, Ohio, and most states. The most common lookback period nationally.
• Lifetime: Illinois, Texas, and several others — every prior DUI counts forever for sentencing purposes.

Lookback applies to sentencing only. A DUI conviction stays on your driving record and criminal history regardless of the lookback window, and insurance companies pull data without regard to it. The lookback affects whether prosecutors charge a new offense as a first, second, or third — not whether the prior conviction exists.

SR-22 and FR-44 Insurance

SR-22 is not insurance — it is a certificate filed by an insurance company with the state DMV proving that the driver carries the minimum required liability coverage. After a DUI conviction, most states require an SR-22 filing as a condition of license reinstatement. Florida and Virginia use a stricter version called FR-44 that requires double the standard liability minimums.

The filing requirement runs 1–5 years depending on the state — Texas at 2 years, Florida at 3, California at 3, with severe or repeat offenses extending up to 5. The SR-22 filing fee itself is small ($25 in most states), but the underlying high-risk insurance policy typically costs 50–100% more than standard coverage. A lapse in coverage during the SR-22 period triggers immediate license suspension, which is why drivers in this period often pay annually upfront rather than monthly.

Practical Defenses to Know About

A DUI charge is not a conviction. Several lines of defense apply across most states, and an experienced DUI attorney will evaluate them within hours of arrest:

• Stop legality: Was there reasonable suspicion for the traffic stop? An unlawful stop suppresses the breathalyzer evidence in most states.
• Field sobriety test administration: The walk-and-turn, one-leg stand, and HGN tests have specific NHTSA protocols. Procedural errors create reasonable doubt.
• Breathalyzer calibration and observation period: The 15–20 minute pre-test observation window is required to rule out mouth alcohol. Missing or incomplete calibration logs can exclude the result.
• Medical conditions: GERD, diabetes, ketosis, and other conditions can spike breathalyzer readings. See our breathalyzer accuracy guide for the full list.
• Rising BAC defense: If you were tested 30–60 minutes after the stop, your BAC may have been rising — meaning your BAC at the time of driving could have been below the limit.
• Independent blood test: Most states give the right to request an independent blood test. If denied, the breathalyzer alone may be insufficient for conviction.

None of these defenses works in isolation. They build on top of a thorough review of the police report, dashcam and bodycam footage, breathalyzer calibration history, and prosecution discovery. A DUI attorney's first job is to identify which combination of defenses applies to a given case before plea negotiations start.
