Arrested for OUI? This Is an Emergency.

OUI arrests often happen late at night or on weekends. Delaying your defense could mean losing crucial evidence, missing court deadlines, or facing RMV license suspension without guidance.

If it’s Saturday or Sunday morning, call immediately. Early action can make the difference between a dismissal and a permanent conviction.

OUI, DUI, DWI — What You Need to Know in Massachusetts

Massachusetts uses the term Operating Under the Influence (OUI) for offenses commonly called DUI or DWI in other states.

Important: You don’t have to be driving. Simply operating the vehicle (even stationary with keys in the ignition) can trigger a charge. A skilled attorney will examine every detail.

What the Commonwealth Must Prove

To secure a conviction, the prosecution must prove beyond a reasonable doubt:

  1. You were operating a vehicle

  2. On a public way or area accessible to the public

  3. While under the influence of alcohol and/or drugs

Each element can be challenged — and often is by experienced OUI defense lawyers.

Real Trial Results — Not Just Plea Deals

Last week on Tuesday, 3 March 2026, NOT GUILTY: In Commonwealth of Massachusetts v. Defendant, Docket No. 2567 CR 1007, after trial, my client was found NOT GUILTY of Operating a Motor Vehicle While Under the Influence of Alcohol (OUI, DUI or DWI), and Child Endangerment While OUI, having recorded a breath test of .08*.

Last week on Monday, 2 March 2026, DISMISSED:  In Commonwealth of Massachusetts v. Defendant, Docket No. 1669 CR 1072, Charges of Operating a Motor Vehicle While Under the Influence of Alcohol (OUI, DUI or DWI) against my client were DISMISSED on the day of trial despite recording a breath test of .12.*

In this matter we filed a Motion to Withdraw Plea and a New Trail pursuant to Commonwealth v. Hallinan, 491 Mass. 730 (SJC 13301) (2023) for this ten (10) year old case. Pursuant to the new court decision in Hallinan if you:  “pleaded guilty or who were convicted after trial, and the evidence against whom included breath test results from an Alcotest 9510 device last calibrated and certified prior to April 18, 2019, [you are] entitled to a conclusive presumption of egregious government misconduct.”

What this decision means to you: in most instances the court will vacate your prior judgement and grant you a new trial.  In the new trial the breath test will be excluded AND YOU FACE NO ADDITIONAL PENALTY.  Often times the Commonwealth is unable to produce a witness for these older cases as a result of the passage of time. Thus, the prior OUI conviction disappears with no risk to the defendant. This becomes especially important to individuals charged with Second or Subsequent Offense Operating a Motor Vehicle While Under the Influence of Alcohol (OUI, DUI or DWI) who are faced with much harsher penalties UNLESS the prior OUI convictions are overturned.

Trial experience is critical — prosecutors respect attorneys who are prepared to fight.

Specialized OUI Defense Matters

A general attorney will miss defenses. A top-rated OUI attorney focuses on:

  • Field Sobriety Test flaws (walk-and-turn, one-leg stand)

  • Breathalyzer and Alcotest 9510 challenges

  • Blood test reliability and chain of custody issues

  • Illegal stops and unconstitutional searches

Defense Across Massachusetts Courts

While deeply experienced in Worcester County, I also handle cases in:

  • Middlesex County: Framingham, Lowell, Cambridge

  • Norfolk County: Dedham and surrounding courts

  • Bristol County and other Massachusetts courts

Local court knowledge matters: judges, prosecutors, and procedures vary.

RMV Hearings & License Suspensions

OUI arrests trigger two parallel battles:

  1. Criminal case in court

  2. Administrative RMV process

Immediate action may allow hardship (“Cinderella”) licenses so you can get back to work or school while your case is pending.

Alternative Outcomes

Depending on circumstances:

  • 24D / CWOF: Avoids a conviction

  • Charge reductions

  • Case dismissal

  • Not Guilty after trial
