Motor vehicle homicide penalties in Massachusetts depend on the specific charge under M.G.L. c. 90, § 24G. Yes, a conviction can result in jail or prison time, but the sentence varies depending on whether prosecutors charge the felony or misdemeanor version of the offense. The felony offense carries a mandatory minimum one-year state prison sentence that cannot be suspended. The misdemeanor offense may allow probation, a suspended sentence, or a fine, depending on the circumstances of the case.
Another important rule is that, under the Massachusetts Supreme Judicial Court’s decision in Millican, a continuance without a finding (CWOF) is not available for any motor vehicle homicide charge under § 24G. Understanding these sentencing rules, mandatory minimum penalties, license consequences, and available defense strategies is essential if you or a loved one is facing prosecution.
What The Statute Says: Misdemeanor Versus Felony
Section 24G splits motor vehicle homicide into three subsections. Two of them drive most prosecutions.
Felony — § 24G(a): The prosecution must prove that the driver was operating under the influence (or with a BAC of .08 or above), drove negligently or recklessly, and caused another person’s death. Exposure runs from one to two and a half years in the house of correction up to two and a half to fifteen years in state prison, plus a fine of up to $5,000. A one-year mandatory minimum applies on every felony conviction.
Misdemeanor — § 24G(b): The prosecution must prove either operating under the influence and causing death, or operating negligently and causing death — but not both. Exposure runs from thirty days up to two and a half years in the house of correction, or a fine of $300 to $3,000, or both.
A third subsection — § 24G(c), reckless homicide by motor vehicle — carries up to two and a half years in the house of correction or up to five years in state prison, without a mandatory minimum.
A first-offense conviction under any subsection triggers a fifteen-year license revocation. A second offense carries lifetime revocation.
Can You Get Probation For Motor Vehicle Homicide in Massachusetts?
This is where the misdemeanor-versus-felony line matters most.
For a § 24G(b) misdemeanor, probation is on the table. A judge can impose a suspended sentence with probation conditions instead of straight jail time, particularly when mitigating factors are strong and aggravating factors are limited. A straight fine, with no incarceration at all, also fits within the statutory range.
For a § 24G(a) felony, probation is not available during the one-year mandatory minimum. The statute is explicit: the court cannot reduce the sentence below one year, cannot suspend it, and the person convicted is not eligible for probation, parole, furlough, or any deduction until the year is served. Parole eligibility opens up after that, but the first year is locked in.
Mandatory Jail Time and The Millican Rule
Two rules cut off otherwise routine dispositions in § 24G cases.
The first is the felony mandatory minimum. A § 24G(a) conviction means at least one year of actual incarceration. There is no probation workaround once the court enters the conviction.
The second is the Millican rule. In Commonwealth v. Millican, the Supreme Judicial Court held that the statutory bar on continuances without a finding and on placing cases “on file” applies to every subsection of § 24G — felony and misdemeanor alike. A § 24G prosecution cannot resolve with a CWOF, even on the misdemeanor side. The case ends in a dismissal, an acquittal, a not-guilty verdict, or a conviction with a sentence.
That makes pretrial strategy — motions to suppress, motions to dismiss, attacks on causation, and challenges to the OUI evidence — far more important in a § 24G case than in a routine motor vehicle charge. There is no soft landing once a conviction enters.
Aggravating and Mitigating Factors at Sentencing
Once a conviction is on the books, both sides argue the same statutory range. The judge’s choice within that range turns on the facts of the crash and the person standing at the bench.
Common aggravating factors include a high BAC well above .08, prior OUI convictions, excessive speed or reckless maneuvers, multiple deaths from a single incident, leaving the scene, and aggressive driving captured before the crash. Each death can support a separate § 24G count, and the court has discretion to run those sentences consecutively rather than concurrently.
Common mitigating factors include no prior criminal record, immediate cooperation with first responders and police, voluntary entry into substance-use treatment well before sentencing, steady employment and family responsibilities, genuine remorse, and acceptance of responsibility through an early plea where appropriate.
What Happens at a Sentencing Hearing
A § 24G sentencing hearing typically follows a presentence investigation by the Probation Department. The prosecutor presents the Commonwealth’s recommendation, often backed by victim impact statements from the family of the deceased. Family members can address the court directly about the loss and the recommended sentence.
The defense then presents the case in mitigation. Character letters from employers, clergy, family, and community members carry real weight when they are specific and credible — general statements do little, while detailed letters describing the defendant’s role in family life, work history, and conduct since the crash can move a judge. Documentation of completed treatment, counseling, and any restitution already paid also matters. The defendant usually addresses the court, and that allocution needs to reflect genuine understanding of the harm caused.
Restitution can include funeral and burial expenses, outstanding medical bills, and lost financial support. Courts commonly order it as a condition of probation in misdemeanor cases and as a condition of any post-incarceration probation in felony cases. After hearing from both sides, the judge announces the sentence.
The sentencing hearing is often the single most important moment in the case for the person being sentenced. Preparation makes the difference between the bottom and the top of the statutory range.
Facing a § 24G charge in Massachusetts?
A motor vehicle homicide charge is one of the most serious cases the District Court or Superior Court handles. The decisions made in the first weeks — preserving the scene, retaining an accident reconstruction expert, navigating police questioning — shape what is possible at sentencing months or years later.
If you are facing these allegations, working with an experienced Boston criminal defense attorney as early as possible can help protect your rights, preserve critical evidence, and build a strong defense from the outset.
