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 M.G.L. c. 90, Sec. 24:

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

 

This week on Tuesday, 15 September 2026, NOT GUILTY: In Commonwealth of Massachusetts v. Defendant, Docket No. 2548 CR 0137, after trial, my client was found NOT GUILTY of Operating a Motor Vehicle While Under the Influence of Alcohol (OUI, DUI or DWI), Second Offense, despite having recorded a breath test of .26. *

In this matter our Motion to Suppress the Breath Test pursuant to Massachusetts General Law, Chapter 90, Section 24K and/or with the requirements of 501 Code Mass. Regs. §2.13(3).  Commonwealth v. Pierre, 72 Mass.App.Ct. 230, 890 N.E.2d 152 (2008), was allowed.

Thereafter, the prosecution was left with evidence only of the police officer’s opinion concerning our client’s performance on standardized field sobriety tests, so called FST’s.

We proceeded to a Jury Trial.

Almost 35 years ago I learned in trial work to “never ask a question to which you do not know the answer.”

However, sometimes with a proper setup, a question can be phrased in a way such that you win… no matter what the answer.

THE SETUP:

She then told you that as a result of the stroke she had difficulty with the entire left side of her body, correct?

Now at this time its roughly 1:00 AM in the morning, correct?

Its dark out, correct?

Its February so its cold out, correct?

The tests are being conducted roadside in public so they are in full view of anyone in the area, correct?

Your armed and in full uniform, correct?

You’re in a fully marked cruiser, correct?

Now another officer has arrived on scene to assist, correct?

Sgt, correct?

My client has told you she suffered from a stroke which affected the entire left side of her body, correct?

And we have provided certified medical records that she suffered from a stroke correct?

You were trained that these test become unreliable when the subject, my client, suffers from a preexisting medical condition like a stroke correct?

My client is significantly overweight, correct?

You were trained that these test become unreliable when the subject, my client, is significantly overweight correct?

My client is wearing three-inch heels, correct? (photo of 3 inch heel boots introduced and confirmed)

You were trained that these test become unreliable when the subject, my client, is wearing heals larger than 1 inch correct?

THE QUESTION:

THESE ARE FAIRLY DIFFICULT TEST CONDITIONS WOULDN’T YOU AGREE? (Looking toward the Jury, not the officer.)

It does not matter what the officer’s response is….

If he answers YES, he acknowledges that the tests upon which he based his opinion are unfair/useless.

If he answers NO, in light of the setup he loses all credibility with the jury – his OPINION becomes unfair/useless.

In this matter, this fair and compassionate police officer answered that he believed the tests performed under the above described conditions were fair… our result: NOT GUILTY.

A note: the above case on 15 September 2026, NOT GUILTY and the below case on 13 August 2026, NOT GUILTY are two different cases in which both defendants were wearing 3-inch heels during FSTs, photographs of which were introduced at trial and confirmed by the arresting officer.

On Thursday, 13 August 2026, NOT GUILTY: In Commonwealth of Massachusetts v. Defendant, Docket No. 2534 CR 0812, after trial, my client was found NOT GUILTY of Operating a Motor Vehicle While Under the Influence of Alcohol (OUI, DUI or DWI), *

In this matter according to the trooper my client committed multiple minor motor vehicle infractions prior to being stopped. The trooper testified that he witnessed these infractions over an approximately two-minute period. We acquired and reviewed all video including the front facing cruiser camera. In this video, which lasted 1:43 seconds prior to the stop, my client made one minor lane violation when the vehicle in front of her applied its brakes.

The trooper also testified that my client had slurred speech. We acquired the rear seat cruiser camera footage showing my client speaking in a perfect, clear and crisp manner. When questioned about her speech in his own video the trooper relented and admitted that her speech was fine.

The trooper then administered a battery of field sobriety tests roadside in heavy traffic while my significantly overweight client was wearing THREE-INCH HEELS. We introduced the shoes as evidence and the trooper accurately testified that administering these tests to a subject roadside who is overweight and wearing THREE-INCH HEELS makes these tests unfair (difficult or impossible to perform). We also introduced certified medical records showing that my client had suffered and torn ACL 1 year prior to the stop. The trooper also accurately testified that this preexisting injury may have made it difficult for my client to perform these tests, all having nothing to do with voluntary intoxication.

Our result: NOT GUILTY.

On Wednesday, 12 August 2026, NOT GUILTY: In Commonwealth of Massachusetts v. Defendant, Docket No. 2648 CR 0211, after trial, my client was found NOT GUILTY of Operating a Motor Vehicle While Under the Influence of Alcohol (OUI, DUI or DWI), *

In this matter my client committed a minor motor vehicle infraction by crossing over marked lanes. He refused all tests and was arrested.

The prosecution relied on a bottle of clear liquid in the center cupholder which the officer testified he believed was alcohol. Upon inspection of the exhibit at trial, the bottle was full. Thus, on cross examination of the Officer I inquired as to the amount of liquid in the bottle. The officer as always testified fairly and honestly that the bottle was full and therefore, if it did contain any alcohol, it appears that little to no alcohol was consumed from that container.

After pointing out the circumstantial nature of the remainder of the commonwealth’s evidence, my client was found NOT GUILTY.
