TL;DR:
- In Massachusetts, third and subsequent OUI offenses automatically become felonies, with escalating penalties. An OUI also becomes a felony if it results in serious injury or death, regardless of prior convictions. Convictions remain on your criminal record for life, but driving records can be cleared after 10 years with a formal request.
An OUI (Operating Under the Influence) is a felony in Massachusetts starting at the third offense, or immediately when the incident causes serious bodily injury or death. Massachusetts uses the term OUI rather than DUI, though both refer to the same offense: operating a vehicle while impaired by alcohol or drugs. Under Massachusetts General Laws (M.G.L.) c. 90, first and second OUI offenses are misdemeanors. The third offense triggers automatic felony status, and certain aggravated circumstances can elevate even a first offense to a felony. Knowing where your charge falls on this scale is the first step toward understanding what you are facing.
Is an OUI a felony in Massachusetts based on offense count?
Massachusetts classifies OUI charges on a clear escalating scale. The number of prior convictions on your record determines whether you face a misdemeanor or a felony.
First and second offenses: misdemeanors
A first offense OUI carries a maximum of 2.5 years in jail and a fine up to $5,000, along with a one-year license suspension. That maximum sentence is rarely imposed for a first offense, but the possibility exists. A second offense remains a misdemeanor but brings steeper penalties, including a mandatory ignition interlock device (IID) requirement upon license reinstatement.
Third and subsequent offenses: felonies
A third offense OUI is automatically a felony under Massachusetts law. The penalties reflect that elevated status:
- Jail time: At least 150 days, up to 5 years in state prison
- Fine: $1,000–$15,000
- License suspension: 8 years
- IID: Mandatory upon reinstatement
Each subsequent offense after the third carries longer minimums. A fourth offense requires a minimum of 1 year in jail and a fine between $1,500 and $25,000. A fifth or higher offense carries a minimum of 24 months in jail, fines between $2,000 and $50,000, and lifetime license revocation. That lifetime revocation is permanent. There is no path back to driving privileges after a fifth conviction.
When does a first OUI become a felony?
Offense count is not the only trigger for felony status. Massachusetts law creates a separate felony category for OUI incidents that cause serious harm, regardless of your prior record.
Under M.G.L. c. 90, § 24L, an OUI charge escalates to a felony when it results in serious bodily injury or death. This applies even to a first-time offender. OUI manslaughter can carry penalties up to 15 years in state prison. That is a longer potential sentence than a standard third-offense felony OUI.
Serious bodily injury includes broken bones, permanent disfigurement, loss of a limb, or any injury that creates a substantial risk of death. A single-car accident where a passenger is seriously hurt qualifies. A crash that kills another driver qualifies. The law does not require a prior record to impose felony-level consequences in these situations.
Pro Tip: If your OUI charge involves an accident with injuries, treat it as a felony matter from day one, even if this is your first offense. The charges can escalate quickly, and early legal representation makes a measurable difference in how the case develops.
What are the penalties for felony vs. misdemeanor OUI charges?
Understanding the full penalty range helps you assess what is at stake. The table below compares OUI penalties by offense level under Massachusetts law.
| Offense level | Classification | Jail time | Fine | License suspension |
|---|---|---|---|---|
| First offense | Misdemeanor | Up to 2.5 years | Up to $5,000 | 1 year |
| Second offense | Misdemeanor | Up to 2.5 years | Up to $10,000 | 2 years |
| Third offense | Felony | 150 days–5 years | $1,000–$15,000 | 8 years |
| Fourth offense | Felony | 1 year minimum | $1,500–$25,000 | 10 years |
| Fifth or more | Felony | 24 months minimum | $2,000–$50,000 | Lifetime |
| OUI causing injury/death | Felony | Up to 15 years | Varies | Varies |
Beyond jail and fines, several additional consequences apply across offense levels:
- Ignition interlock devices: IID use is mandated for second and subsequent offenses as a condition of license reinstatement.
- Hardship licenses: Available for some offenders during suspension periods, but eligibility narrows significantly with each felony conviction.
- Probation: Courts frequently impose probation alongside or instead of jail time for lower-level offenses.
- Alcohol education programs: Required for first offenders who seek a continuance without a finding (CWOF), a deferred disposition option that avoids a formal conviction.
The full range of OUI fines and associated costs extends well beyond the statutory amounts once you factor in court fees, attorney fees, and increased insurance premiums.
How does an OUI affect your criminal and driving records?
An OUI conviction stays on your criminal record permanently in Massachusetts. There is no automatic expungement after a set number of years. Your driving record tells a different story. OUI convictions on your driving record can be removed after 10 years upon a formal request to the Registry of Motor Vehicles (RMV). That distinction matters because insurers and employers often check both records separately.
The long-term consequences of a felony OUI reach well beyond the courtroom:
- Employment: Many employers conduct criminal background checks. A felony OUI can disqualify you from jobs requiring a commercial driver’s license (CDL), security clearance, or professional license.
- Insurance: Auto insurance rates increase substantially after any OUI conviction. A felony conviction can result in policy cancellation.
- Travel: A felony conviction can restrict entry into Canada and other countries.
- Chemical test refusals: Massachusetts is an implied consent state, meaning refusing a breathalyzer triggers an automatic administrative license suspension. That refusal is not a criminal offense, but it affects your license independently of any court outcome.
Record sealing is possible for some OUI convictions under Massachusetts law, but felony OUI cases face stricter eligibility requirements and waiting periods. An attorney can assess whether sealing is an option in your specific situation.

What I’ve learned defending OUI cases in Massachusetts
After years of representing clients facing OUI charges across Massachusetts, one pattern stands out clearly. People consistently underestimate how quickly a misdemeanor OUI situation can shift into felony territory. A second offense with an accident, a prior conviction from another state that counts toward your Massachusetts total, or a passenger who sustains an injury can all change the charge classification before you fully understand what happened.
The other misconception I see regularly is that a first offense is “not serious.” A first OUI is a misdemeanor, but it carries real consequences including possible jail time, a one-year license suspension, and a permanent criminal record. How you handle a first offense also shapes your exposure if you are ever charged again. A continuance without a finding (CWOF) on a first offense still counts as a prior OUI for sentencing purposes on a second charge. That surprises many people.
The most practical advice I can offer is this: contact a defense attorney before you speak to anyone else. The decisions made in the first 48 hours after an OUI arrest often determine the trajectory of the entire case.
