When a fatal crash leads to criminal charges in Massachusetts, people often hear “motor vehicle homicide” as if it were one offense. It is not. G.L. c. 90, § 24G creates related tracks — some felonies, one a misdemeanor — depending on impairment, negligence, recklessness, or a combination, and whether that operation caused another person’s death.
This guide explains § 24G in plain English for Medford, Greater Boston, and nearby courts. It is educational, not a prediction about any case. The complaint’s subsection and the evidence control. Penalties and license stakes make early review of the charging papers matter.

Motor vehicle homicide is not one charge
Section 24G has three charging tracks and a separate license subsection:
- Subsection (a) — felony: impaired operation (or .08 BAC or greater) and reckless or negligent operation so as to endanger, causing death.
- Subsection (b) — misdemeanor: impaired operation causing death, or negligent operation causing death (without the combined impairment-plus-negligence/recklessness package of (a)).
- Subsection (c) — felony: reckless operation causing death (no impairment element).
- Subsection (d) — Registry revocation after conviction under (a), (b), or (c).
District Court model jury instructions split these into separate forms (the 5.140–5.166 series). The complaint should identify the theory charged. “Motor vehicle homicide” is a family of offenses, not one checklist.
The shared building blocks: operation, way, and causation
Across § 24G, several ideas usually recur. The Commonwealth must prove each element of the charged theory beyond a reasonable doubt — not the other way around.
Operation. Jury instructions treat operation more broadly than everyday “driving.” It includes ordinary driving and intentional acts that tend to set the vehicle in motion — for example, manipulating a gear shift or ignition while in the vehicle so that the vehicle will move. Who was operating can be contested after a crash.
Way or place. The statute requires a way or place to which the public has a right of access, or access as invitees or licensees. Public roads usually qualify; lots and private drives can still qualify depending on access.
Causation of death. The Commonwealth must prove the defendant’s act or acts caused another person’s death. Model instructions describe a “but for” factual-cause question and a foreseeability question — whether a reasonable person would have foreseen that the conduct could cause serious injury or death, and whether death was a natural and probable consequence. An accident alone does not prove negligence or recklessness. A victim’s comparative negligence is generally not a criminal defense, though causation remains case-specific.
Subsection (a): felony OUI or impairment plus reckless or negligent operation causing death
Subsection (a) is the most severe § 24G package. The Commonwealth must prove operation on a qualifying way or place; .08-or-greater BAC or under the influence of intoxicating liquor, marijuana, certain drugs, or certain toxic vapors; reckless or negligent operation so that public lives or safety might be endangered; and causation of death. Impairment (or per se BAC) plus reckless-or-negligent operation is what separates (a) from (b).
Punishment: state prison for not less than two and one-half years nor more than fifteen years and a fine of not more than $5,000, or jail or house of correction for not less than one year nor more than two and one-half years and a fine of not more than $5,000.
The statute’s early-release language is easy to overstate. The sentence shall not be reduced to less than one year, nor suspended, and a person convicted under (a) shall not be eligible for probation, parole, or furlough, or receive any sentence deduction, until at least one year has been served. Limited temporary release in custody is allowed only for narrow purposes (funeral of a relative; visit to a critically ill relative; emergency medical or psychiatric care unavailable at the facility; or work release). Prosecutions under § 24G shall not be continued without a finding or placed on file. G.L. c. 276, § 87 does not apply to a person charged under subsection (a).
Practical reading: (a) is a felony with a real floor. It is not accurate to say someone convicted under (a) is simply “eligible for parole and good-conduct deductions” as if the one-year restriction did not exist. After that threshold, eligibility depends on the sentence and correctional and parole rules.
Subsection (b): misdemeanor tracks (impairment causing death, or negligence causing death)
Subsection (b) is the misdemeanor form. It covers two paths: (1) operating at .08 or greater, or under the influence of intoxicating liquor, marijuana, certain drugs, or certain toxic vapors, and by that operation causing death; or (2) operating negligently so that public lives or safety might be endangered and by that operation causing death. Unlike (a), the negligence path does not also require impairment.
Punishment: jail or house of correction for not less than thirty days nor more than two and one-half years, or a fine of not less than $300 nor more than $3,000, or both. There is no state-prison option, so (b) is a misdemeanor under G.L. c. 274, § 1. It is still a death-involved crime: sentencing, CORI, and the fifteen-year first-offense revocation in (d) can reshape a life. Charging choices between (a) and (b) are often critical early issues.
Subsection (c): felony reckless operation causing death
Subsection (c) is reckless homicide by motor vehicle: operation on a qualifying way or place; reckless operation so that public lives or safety might be endangered; and causation of death. Impairment is not an element. The statute defines recklessness as consciously disregarding a substantial and unjustifiable risk that public lives or safety might be endangered. Jury instructions emphasize that recklessness is more than ordinary negligence — roughly, ignoring a grave danger of death or serious injury, or indifference to that danger.
Punishment: jail or house of correction for not more than two and one-half years, or state prison for not more than five years, or a fine of not more than $3,000, or both. Because state prison is authorized, (c) is a felony even if a particular case resolves with house of correction time or a fine.
Negligence vs. recklessness in plain English
Negligence, in these instructions, is a failure to use due care — driving as a reasonable person would not and creating an unnecessary danger that more careful driving could have avoided. Intent to be negligent is not required. Speed, weather, visibility, road design, vehicle condition, traffic, and what others were doing can all matter. Speeding alone is not automatically negligence, but it can be considered with other evidence.
Recklessness is a higher blameworthiness concept. Careless driving is not enough. The Commonwealth must show conscious disregard of a substantial and unjustifiable risk to public lives or safety — or that the person knew or should have known the actions posed a grave danger of death or serious injury and chose to run that risk. An emergency can affect how a reasonable person would have acted; that is a fact question.
Why it matters: recklessness can support the (c) felony without impairment, and reckless or negligent operation can combine with impairment to support (a). Ordinary negligence without impairment points toward the (b) misdemeanor path — still serious, but a different ceiling.
License revocation after a § 24G conviction
Subsection (d) is easy to miss online and hard to ignore in real life. When a motor vehicle is the instrument of the offense, the registrar shall revoke the license or right to operate of a person convicted under (a), (b), or (c) — or punished under G.L. c. 265, § 13 — for fifteen years after a first conviction. For a subsequent § 24G violation, revocation is for life.
No appeal, motion for a new trial, or exceptions stays that revocation. The license or right to operate is restored if the prosecution ultimately terminates in the defendant’s favor. Hardship-license rules familiar from first-offense OUI / 24D practice do not erase a fifteen-year or lifetime § 24G(d) revocation.
How this differs from ordinary OUI and negligent operation to endanger
Ordinary OUI under G.L. c. 90, § 24 alleges impaired or per se .08 operation without a death element. Qualifying first-offense cases may involve alcohol education, 24D-style structures, and RMV suspensions measured in days or months — not § 24G homicide tracks or the fifteen-year first-conviction revocation in § 24G(d).
Negligent operation so as to endanger under G.L. c. 90, § 24(2)(a) is common when nobody dies. Model-instruction notes treat it as a lesser-included offense of negligent or reckless motor vehicle homicide under § 24G(b). A death allegation moves the file into § 24G. Prosecutors may charge more than one theory from one crash; duplicative convictions and multiple-death charging must be read count by count.
Practical defense themes (without predicting outcomes)
Fatal-crash prosecutions are evidence-heavy. Themes that often matter — without promising results — include:
- Operation and identity: who was driving; seating; statements; crash dynamics; witness reliability.
- Way or place: whether the location meets the public-access / invitee-licensee element.
- Impairment and BAC: observations, roadside assessments, breath or blood testing, timing, machine or lab issues, medical explanations, and drug-impairment proof (especially without a .08-style shortcut).
- Negligence or recklessness: whether the driving meets the legal standard — not merely whether an accident happened.
- Causation: but-for and foreseeability; intervening events; whether death was a natural and probable consequence of the alleged conduct.
- Charging theory: whether the file is an (a) felony package, a (b) misdemeanor path, a (c) recklessness felony, or a candidate for reduction.
- Collateral and RMV stakes: subsection (d) revocation and related employment or immigration issues.
Early preservation of scene photos, 911 audio, vehicle data, medical records, and witness contacts can matter as much as later courtroom work. Social-media commentary about a fatal crash rarely helps.
Frequently asked questions
Is motor vehicle homicide always a felony?
No. Subsections (a) and (c) authorize state prison and are felonies. Subsection (b) is a misdemeanor. The police-report label matters less than the statute and subsection on the complaint.
If I am convicted under § 24G(a), am I eligible for parole?
Not until you have served at least one year, under subsection (a)’s express terms. The statute also restricts suspension, probation, furlough, and sentence deductions until that mark. Afterward, eligibility depends on the sentence and correctional and parole rules. Subsections (b) and (c) do not use the same one-year floor language.
What is the difference between negligence and recklessness?
Negligence is failing to drive with due care. Recklessness is consciously disregarding a substantial and unjustifiable risk to public lives or safety. Recklessness is more than ordinary carelessness and can support the (c) felony track without impairment.
Will I lose my license if I am convicted?
Subsection (d) directs a fifteen-year revocation after a first conviction under (a), (b), or (c), and lifetime revocation for a subsequent § 24G violation. An appeal does not stay the revocation. Restoration follows if the prosecution terminates in the defendant’s favor.
How is this different from a first-offense OUI?
Ordinary OUI under § 24 does not require proof that someone died. Section 24G adds a death-causation element and, on conviction, the lengthy revocation rules in § 24G(d). First-offense OUI / 24D and hardship-license posts on this site cover non-homicide pathways.
Can a § 24G case be continued without a finding?
The statute says prosecutions commenced under § 24G shall neither be continued without a finding nor placed on file. Case law has applied that prohibition broadly to prosecutions under the section. Do not assume a 24D-style CWOF from some ordinary OUI cases will be available here.
What should I do after a fatal-crash investigation or charge?
Avoid discussing facts on social media. Preserve paperwork and a written timeline while memories are fresh. Calendar every court and RMV date. Contact counsel promptly so criminal exposure, license consequences, and evidence preservation can be coordinated.
