What Is the Difference Between OUI and DUI in Massachusetts?
In Massachusetts, the terms OUI (Operating Under the Influence) and DUI (Driving Under the Influence) are often used interchangeably.
However, “OUI” is the official legal term used in court and under Massachusetts General Laws Chapter 90, Section 24. While “DUI” is commonly used in everyday language, both refer to the same charge: operating a vehicle under the influence of alcohol or drugs, whether legal or illegal.

What Type of Law Covers OUI/DUI in Westboro?
OUI/DUI offenses in Westboro are governed by both criminal and administrative law, which means your case may involve two separate legal processes—each with serious consequences.
Criminal Law
The criminal side of an OUI charge is handled in District Court, where you face prosecution by the Commonwealth of Massachusetts under Mass. Gen. Laws ch. 90, § 24. This process includes arraignment, pretrial motions, and possibly a trial. If convicted, you may face:
- Jail time
- Fines and court costs
- Probation
- Mandatory alcohol education programs
- A permanent criminal record
The court process determines your criminal guilt and imposes penalties like incarceration and fines.
Administrative Law
At the same time, the Registry of Motor Vehicles (RMV) initiates an administrative process that can result in:
- Immediate license suspension (even before your court date)
- Breathalyzer refusal penalties under the Implied Consent Law
- Ignition interlock device requirements
- Habitual offender designations
These actions are civil—not criminal—but they carry life-changing consequences. The RMV acts as judge, jury, and enforcer during suspension hearings, and success often depends on navigating nuanced procedures and technical requirements.
Most defense attorneys focus solely on court. At Gilman Law, we handle both—and we’ve done it thousands of times. Our deep understanding of how these systems overlap gives our clients a real strategic advantage.
