DWI vs. DWAI vs. Aggravated DWI in New York

New York's impaired driving law, Vehicle & Traffic Law § 1192, contains several distinct charges that people often lump together. The difference between them (sometimes a single hundredth of a percent of blood alcohol content) determines whether you are facing a traffic infraction or a crime, whether your license is suspended or revoked, whether an ignition interlock is mandatory, and how far the charge can be negotiated down.

DWAI: The Only Non-Criminal Charge, With Caveats

Driving While Ability Impaired by alcohol is the one § 1192 charge that is not a crime on a first or second offense; it is a traffic infraction, which is why reducing a DWI to a DWAI is often the central goal of plea negotiations. But three caveats matter. First, the statute has no BAC threshold: the familiar ".05 to .07" range comes from evidentiary presumptions, and a DWAI can be proven on observations alone. Second, the 90-day license suspension is mandatory, not discretionary. Third, a prior conviction under any part of § 1192 within 5 years escalates a DWAI to enhanced penalties, and a third offense within 10 years is a misdemeanor.

Despite the shared name, DWAI-Drugs and DWAI-Combined Influence are misdemeanors carrying the same penalties as DWI. The "non-criminal" character of DWAI applies only to the alcohol version.

DWI: The Misdemeanor Standard

New York charges DWI two ways: per se DWI for a chemical test of .08 or higher (.04 for commercial drivers), and common-law DWI based on evidence of intoxication with no test required, which is why refusing the breath test does not prevent a DWI charge (and triggers its own license revocation and civil penalty). A conviction means a fine of $500–$1,000, up to a year in jail, license revocation for at least 6 months, and (since Leandra's Law took effect in 2010) a mandatory ignition interlock device in every vehicle you own or operate for at least 12 months. Completion of the Impaired Driver Program (IDP) is usually the path to a conditional license during revocation.

Aggravated DWI: Why .18 Changes Everything

At a BAC of .18 (just over twice the legal limit) the charge becomes Aggravated DWI, and two things get materially worse. The minimum license revocation doubles to one year. And under § 1192(10)(d), the charge generally cannot be plea-bargained below a DWI; the DWAI reduction that resolves many ordinary DWI cases is off the table unless the prosecution concludes on the record that the charge isn't supported by the evidence. An Aggravated DWI conviction also raises the floor for the future: a later DWI, DWAI-Drugs, or DWAI-Combined conviction within 10 years carries a minimum 18-month revocation.

The separate felony branch of the statute (commonly called Leandra's Law) makes it a class E felony to drive intoxicated or impaired by drugs with a child of 15 or younger in the vehicle, on a first offense, regardless of BAC level.

Refusing the Chemical Test

Refusing the breath or blood test is its own event with its own consequences, handled by the DMV separately from the criminal case. A refusal brings a civil penalty of $500 ($550 for commercial drivers) and a license revocation of at least one year (at least 18 months if you have a prior alcohol-related incident within 5 years), imposed after a DMV refusal hearing, regardless of how the criminal case turns out. And refusing does not prevent a DWI charge: common-law DWI under § 1192(3) requires no test at all, so prosecutors routinely proceed on the officer's observations. Whether a refusal helped or hurt is one of the first things we evaluate in any case.

Drivers Under 21: The Zero Tolerance Law

A common misconception, repeated on many legal websites, is that a driver under 21 with a BAC of .02 "gets a DWI." Not so. Under New York's Zero Tolerance Law (VTL § 1192-a), a driver under 21 with a BAC of .02 to .07 faces a DMV administrative proceeding, not a criminal charge: a $125 civil penalty, a $100 fee to terminate the suspension, and a 6-month license suspension. But the Zero Tolerance Law is not a shield: an under-21 driver at .08 or higher, or at .05+ with other evidence of impairment, can be charged with DWI or DWAI like any adult.

The Costs Beyond the Fine

The fine is rarely the largest number. An alcohol-related misdemeanor conviction carries $395 in mandatory surcharges and fees ($520 for a felony). Any § 1192 conviction or chemical-test refusal triggers the DMV's Driver Responsibility Assessment: $250 per year for three years, $750 total. And under the DMV's February 2026 point-system overhaul, every § 1192 conviction now also carries 11 points, by itself enough to reach the DMV's suspension threshold of 11 points in 24 months, and potentially a second, points-based assessment on top. Add interlock rental, IDP fees, and insurance consequences, and even a "minimal" disposition is expensive.

Repeat Offenses: Two Separate Systems Working Against You

Repeat offenders face escalation on two independent tracks. The criminal track is in the statute: a second DWI or Aggravated DWI within 10 years is a class E felony, a third a class D felony, and even a second DWAI within 5 years carries enhanced penalties. The administrative track belongs to the DMV, and it got tougher in February 2026: the DMV now permanently revokes the license of a driver with four alcohol- or drug-related incidents in a lifetime (down from five), or three such incidents plus a serious driving offense within a 25-year lookback. Three alcohol-related convictions or refusals within 10 years can also bring permanent revocation, with a waiver request possible only after 5 years. These DMV rules apply on their own force (no felony conviction required), and alcohol-related convictions at every level, DWAI included, count alongside chemical-test refusals.

Your Record: What the Clean Slate Act Changed, and What It Didn't

For years, the standard answer was that a DWAI could never be sealed; New York's general sealing statute for violations, CPL § 160.55, specifically excludes it. That changed on November 16, 2024. Under the Clean Slate Act (CPL § 160.57), a DWAI conviction is now sealed automatically 3 years after sentencing or release, as are misdemeanor DWI convictions; felony DWI convictions seal after 8 years. No petition is required, though sealing is paused by pending charges, probation, or parole.

The critical caveat: Clean Slate seals the criminal record, not the DMV record. The statute expressly leaves Department of Motor Vehicles records untouched. A DWAI remains on your driving abstract for 10 years and a DWI for 15, both remain visible on a lifetime abstract, and both continue to count as priors for repeat-offense enhancement, insurance, and relicensing purposes. Sealing helps with employment and housing checks; it does not reset your standing with the DMV.

Getting Back on the Road

For a DWI charge backed by a .08+ test, New York's Prompt Suspension Law requires the court to suspend your license at arraignment, before any conviction. Acting quickly matters: a hardship privilege (driving to work, school, and medical care) must be requested at that first appearance with proof that you have no reasonable alternative transportation. After 30 days, a pre-conviction conditional license may be available, and after conviction, enrolling in the IDP typically supports a conditional license for work, school, medical, and program travel. Commercial drivers face far harsher rules: an alcohol-related conviction (even a DWAI in a personal vehicle) brings a lengthy CDL disqualification, and no conditional license is ever valid for operating a commercial vehicle.
