DUI Arrest: What to Do, Available Defenses, How We Can Help

A DUI arrest can lead to booking, processing, and an eventual conviction. With competent representation, it is possible to avoid a conviction. The most important rule when interacting with the police is to not say anything and to ask to speak to your lawyer. Call us at any time at 212-233-1233 or email [email protected].

After the stop, if you are suspected of a DUI, the police take you to the station for booking: personal information, photographs, fingerprints, criminal-history check. A conviction can land on your record for fifteen years and follow you in employment, insurance, and licensing.

Two Sides of a DUI Arrest

Every DUI arrest in New York has two sides: criminal and administrative. The criminal side is litigated in Criminal Court or Supreme Court under VTL § 1192 and exposes you to fines, probation, license penalties, and jail. The administrative side is litigated at the DMV and controls your driving privileges — suspensions, revocations, and refusal hearings.

Defenses to a DUI Arrest

Miranda Issues

Miranda rights are rarely read at the roadside because most DUI evidence is gathered before the formal arrest. But after the arrest, custodial interrogation without Miranda warnings makes the resulting statements inadmissible. If you admitted to drinking, driving, or anything else after being placed under arrest and before being warned, those statements can be suppressed.

Failure to Give the Refusal Warning Properly

VTL § 1194(2)(f) requires the police to warn you, in clear and unequivocal language, that refusing a chemical test will result in license suspension and revocation, and that the refusal can be used as evidence. If the warning was incomplete or garbled, the refusal evidence is inadmissible.

Lack of Probable Cause for the Stop

The Fourth Amendment requires that the police have probable cause (or at least reasonable suspicion) before stopping a vehicle. If you were following the rules of the road and the officer pulled you over on a hunch, the stop fails — and the breath test, field sobriety tests, and statements that followed are fruit of the poisonous tree.

Other Defenses

• Failure to calibrate the breathalyzer within statutory time limits
• Medical conditions (GERD, diabetes, neurological issues) that mimic intoxication
• Rising-BAC defenses where the test was administered far after driving
• Improper administration of standardized field sobriety tests
• Chain-of-custody breaks in blood-test cases

The Charges You Are Actually Facing

The booking sheet matters. Police and prosecutors usually charge in the alternative, stacking subsections of VTL § 1192 so that the case survives if any one theory fails. Knowing which subsection you are charged under controls everything that follows — the penalties, the plea posture, and which evidence the prosecution must put in.

• VTL § 1192(1) — driving while ability impaired by alcohol. Traffic infraction, not a crime. 90-day license suspension, up to 15 days jail (rarely imposed), fine up to $500 plus surcharge.
• VTL § 1192(2) — per se DWI with BAC of .08 or more. Unclassified misdemeanor. Six-month license revocation, up to one year in jail, fine up to $1,000.
• VTL § 1192(2-a)(a) — Aggravated DWI with BAC of .18 or more. Misdemeanor on a first offense, but longer revocation and higher minimum fines.
• VTL § 1192(2-a)(b) — Leandra's Law. Driving impaired with a child fifteen years old or younger in the vehicle. Automatic Class E felony on a first offense.
• VTL § 1192(3) — common-law DWI. No required BAC number; the proof is observation, performance on field tests, and admissions. Often paired with 1192(2) so the prosecution can convict even if the breath result is thrown out.
• VTL § 1192(4) — DWAI drugs. Drug impairment proven through observation, drug recognition expert testimony, and toxicology.
• VTL § 1192(4-a) — combined influence of alcohol and any drug or drugs.

A prior alcohol- or drug-related conviction within ten years elevates a misdemeanor DWI to a Class E felony under VTL § 1193(1)(c). A second prior within ten years pushes it to a Class D felony with mandatory state prison exposure. The "ten years" runs from the date of the prior conviction, not the date of the prior arrest.

Booking, Arraignment, and the First 24 Hours

After processing at the precinct, you are held for arraignment. In Manhattan and the other boroughs, arraignments run around the clock; in most cases the wait is between several hours and a full day. At arraignment, the prosecution serves the accusatory instrument, gives notice of any statements and identifications it intends to use under CPL § 710.30, and asks the court to impose conditions of release.

If a chemical test was refused or showed .08 or higher, the court must suspend your license pending prosecution at arraignment. You leave court without a license to drive. A pre-conviction conditional license is available in most cases for work, school, medical appointments, and child-care obligations — we apply for it the next morning.

Field Sobriety Tests — What the Officer Actually Did

The three standardized field sobriety tests endorsed by NHTSA are the horizontal gaze nystagmus, the walk-and-turn, and the one-leg stand. Each test has a fixed instruction script, a fixed set of scoring "clues," and a fixed environmental protocol. Departures from the protocol degrade the test's predictive value, which is the point of attack on cross-examination.

HGN is the most overstated. Officers often testify that a "lack of smooth pursuit" or an "onset of nystagmus prior to 45 degrees" indicates alcohol impairment. Nystagmus has many noncriminal causes — fatigue, caffeine, prescription medication, head injury, certain neurological conditions, and flashing roadside lights. The walk-and-turn and one-leg stand require a flat, dry, hard, non-slippery surface; many roadside arrests happen on a gravel shoulder or on a sloped highway entrance. Footwear above two inches disqualifies the suspect from valid testing under NHTSA's own manual.

Breath Testing — The Machine and the Operator

New York stations use the Intoxilyzer 9000 and, in some agencies, the DataMaster DMT. Both are infrared spectrometry instruments calibrated on a fixed schedule with simulator solutions of known alcohol concentration. The result on the printout is only as good as the calibration log, the maintenance log, the operator's permit, and the 20-minute observation period that must precede the test.

The 20-minute rule exists to ensure that no mouth alcohol, regurgitation, vomiting, smoking, or foreign substance contaminates the breath sample. Officers fill out a checklist asserting that they "continuously observed" the subject for 20 minutes. Body-worn camera footage often shows them on a phone, completing paperwork, or out of the room entirely. That is the cross.

Blood Cases and the Warrant Requirement

If a breath test is refused or impossible (unconscious driver, hospitalized driver, serious physical injury), the police may apply for a court order under VTL § 1194(3) or pursue a warrant. After Missouri v. McNeely and Mitchell v. Wisconsin, the natural dissipation of alcohol does not by itself create exigent circumstances. Warrantless nonconsensual blood draws are presumptively unconstitutional and the evidence is suppressible.

The DMV Track Runs in Parallel

While the criminal case is pending, the DMV runs its own proceeding. If you refused the chemical test, a refusal hearing is scheduled under 15 NYCRR Part 127, usually within fifteen days of arraignment. The hearing officer decides four narrow questions: lawful stop, lawful arrest, proper refusal warning, and refusal. Win the hearing and the refusal evidence is excluded from the criminal trial; lose it and your license is revoked for a year and you owe a $500 civil penalty, separately from anything that happens in court. See our implied consent law page for the mechanics.

Sentencing Exposure and Collateral Consequences

Even a first-offense misdemeanor DWI under VTL § 1192(2) or (3) carries a mandatory ignition interlock requirement under Leandra's Law and VTL § 1193(1)(b)(ii) on the defendant's own vehicle and any vehicle the defendant operates, for at least twelve months. There are mandatory state surcharges, a mandatory crime-victim assistance fee, and a three-year $250-per-year driver responsibility assessment from the DMV. Insurance carriers see the conviction and reprice the policy or non-renew it.

For non-citizens, a DWI conviction is not automatically a deportable offense, but a DWAI-drugs plea or a felony DWI can carry immigration consequences. For licensed professionals — doctors, nurses, lawyers, teachers, brokers — the conviction triggers reporting obligations to the relevant licensing body. For CDL holders, even an off-duty first-offense DWI in a personal vehicle results in a one-year CDL disqualification under federal law, regardless of the disposition of the underlying VTL charge.

What You Should Do Now

• Do not call the precinct to "explain." Whatever you say is recorded and turned over to the prosecutor.
• Do not post about the arrest on social media. Prosecutors subpoena posts and direct messages.
• Preserve your phone's location history, dashcam footage, and any text messages from before and after the stop.
• Write down everything you remember about the stop — what the officer said, where the tests were performed, what the road surface looked like, how long the wait was at the station. Memory fades fast.
• Get a copy of any paperwork you were handed at the precinct. The pink temporary license, the refusal report, and the desk appearance ticket all carry deadlines.
• Call a lawyer before the DMV refusal hearing date. Missing that hearing means automatic revocation.
