Operating Under the Influence (OUI/DWI/DUI)
Operating Under the Influence in Massachusetts
In Massachusetts, the offense commonly called drunk driving or drugged driving is known as Operating Under the Influence, or OUI. In other states, similar charges may be called DUI or DWI, but Massachusetts law uses the term OUI.
An OUI charge can involve alcohol, drugs, marijuana, prescription medication, narcotics, depressants, stimulants, or other intoxicating substances. A conviction can affect your driver’s license, criminal record, employment, insurance, and future opportunities. Even a first offense should be taken seriously.
At The Law Offices of Elliot Savitz & Scott Bradley, we defend clients facing OUI, DUI, DWI, negligent operation, license suspension, breath test refusal, and related motor vehicle charges throughout Boston and Massachusetts.
What Is OUI in Massachusetts?
Operating Under the Influence is governed by Massachusetts General Laws Chapter 90, Section 24. Under this law, a person may be charged with OUI if they operate a motor vehicle on a public way, or in a place where the public has access, while under the influence of intoxicating liquor, marijuana, narcotic drugs, depressants, stimulant substances, or certain inhaled toxic vapors.
A person may also be charged with OUI alcohol if their blood alcohol concentration is 0.08% or greater. However, prosecutors do not always need a breath test result to pursue an OUI case. They may try to prove impairment through officer observations, driving behavior, field sobriety tests, statements, video evidence, and other facts.
OUI Liquor vs. OUI Drugs
Massachusetts OUI cases may involve alcohol or drugs. An OUI liquor case usually involves allegations that alcohol impaired the driver’s ability to operate safely. An OUI drugs case may involve marijuana, prescription medication, illegal drugs, or other substances that prosecutors claim impaired the driver.
OUI drug cases can be more complicated than alcohol cases because there may not be a simple breath test equivalent. Prosecutors may rely on officer observations, alleged admissions, drug recognition evidence, blood testing, prescription records, or other evidence. The defense may challenge whether the substance actually impaired the driver’s ability to operate safely.
Do You Have to Be Driving When Police Find You?
You do not necessarily have to be actively driving when police first encounter you to face an OUI charge. The Commonwealth must prove operation, but operation can sometimes be based on evidence that the person drove or controlled the vehicle at some point while allegedly impaired.
Examples may include situations where a person is found:
- Stopped at a traffic light;
- Sleeping in a vehicle;
- Pulled over on the side of the road;
- In a parking lot open to the public;
- Near a disabled vehicle; or
- Outside a vehicle after an alleged crash.
These cases often turn on whether the Commonwealth can prove operation, where the vehicle was located, whether the public had access to the location, and whether the person was under the influence at the relevant time.
What Must Prosecutors Prove in an OUI Case?
To convict someone of OUI in Massachusetts, the Commonwealth generally must prove beyond a reasonable doubt that:
- The defendant operated a motor vehicle;
- The operation occurred on a public way or a place where the public had access; and
- The defendant was under the influence of alcohol, drugs, marijuana, or another covered intoxicating substance at the time of operation.
In an alcohol case, prosecutors may also proceed under a per se theory if there is admissible evidence that the person’s blood alcohol concentration was 0.08% or greater. However, breath test evidence can be challenged depending on calibration, procedure, observation period, machine reliability, and whether the test was administered properly.
Evidence Prosecutors May Use in an OUI Case
Prosecutors may try to prove impairment using many types of evidence, including:
- Alleged erratic driving;
- Traffic violations;
- Odor of alcohol or marijuana;
- Red or glassy eyes;
- Slurred speech;
- Unsteadiness;
- Statements about drinking or drug use;
- Open containers or substances in the vehicle;
- Field sobriety tests;
- Breath test or blood test evidence;
- Body camera or cruiser video;
- Witness statements; and
- Crash evidence.
None of this evidence automatically proves guilt. Medical conditions, fatigue, anxiety, injury, weather, poor footwear, road conditions, lighting, nervousness, and other explanations may affect how a person appears during an OUI stop.
What Should You Do If You Are Stopped for OUI?
If you are stopped by police and suspected of OUI, how you respond matters. You should remain calm, be respectful, and avoid making statements that could be used against you.
Be Polite and Calm
Keep your hands visible, provide your license and registration when requested, and avoid arguing with the officer. Being polite does not mean you must answer every question about where you were, what you drank, whether you used drugs, or how much you consumed.
Be Careful About Self-Incrimination
Statements made during an OUI stop may be used in court. If the officer asks questions designed to gather evidence, you can politely decline to answer and ask to speak with an attorney.

Understand Field Sobriety Tests
Field sobriety tests may include walking a line, standing on one leg, following a pen or finger with your eyes, reciting the alphabet, or counting backward. These tests are often used to gather evidence of impairment.
In Massachusetts, refusing field sobriety tests is different from refusing a chemical breath test after arrest. Field sobriety test refusal generally does not carry the same automatic RMV license suspension as refusing a chemical test. However, every situation is fact-specific, and you should remain polite if you decline.
Understand Breath Test Refusal Consequences
Refusing a breathalyzer or other chemical test after arrest can have immediate license consequences. According to Mass.gov, if a person arrested for OUI refuses a chemical test, the arresting officer will immediately take custody of the person’s license or right to operate, provide written notice of suspension or revocation, impound the vehicle for 12 hours, and notify the RMV.
A chemical test refusal is not a separate criminal offense in Massachusetts, but it can trigger an administrative license suspension. The length of the suspension depends on your age, prior OUI history, and other factors. You should speak with an attorney immediately about your rights, deadlines, and any possible appeal.
For official information, see Mass.gov’s page on alcohol and drug suspensions for drivers over 21.
Penalties for OUI in Massachusetts
OUI penalties depend on whether it is a first offense or subsequent offense, whether there was a chemical test refusal, whether anyone was injured, whether a child was in the vehicle, and whether other charges are involved.
Possible consequences may include:
- Driver’s license suspension;
- Probation;
- Fines and fees;
- Alcohol or substance education programs;
- Ignition interlock requirements in certain cases;
- Jail or house of correction time;
- Increased insurance costs;
- Employment consequences, especially for commercial drivers or jobs requiring driving;
- Immigration consequences for non-citizens in some cases; and
- A criminal record if convicted.
First-offense OUI cases may sometimes be resolved through probation and alcohol education programs, depending on the facts and eligibility. Repeat offenses carry more serious penalties, including mandatory minimum sentencing in certain circumstances.
Common Defenses to OUI Charges
An OUI charge is not the same as a conviction. The Commonwealth must prove the case beyond a reasonable doubt, and many OUI cases have defenses.
Common defense issues may include:
- Unlawful stop: Police lacked reasonable suspicion to stop the vehicle.
- No operation: The Commonwealth cannot prove the defendant operated the vehicle.
- No public way: The alleged operation did not occur on a public way or place where the public had access.
- No impairment: The evidence does not prove the person was under the influence at the time of operation.
- Medical or physical conditions: Illness, injury, fatigue, anxiety, or disability affected appearance or performance.
- Field sobriety test problems: Tests were improperly administered or unreliable under the circumstances.
- Breath test issues: The machine, procedure, observation period, calibration, or operator compliance may be challenged.
- Timing issues: The evidence does not prove impairment at the time of operation.
- Unreliable observations: Police reports or testimony may be inconsistent with video evidence or witness accounts.
- Improper statements: Statements may be challenged if obtained unlawfully.
