Maryland Manslaughter Laws: Voluntary, Involuntary, Vehicular (2026)

Maryland treats manslaughter as a common-law crime: no statute defines it, but Criminal Law 2-207 makes it a felony punishable by up to 10 years in prison, or alternatively up to 2 years in a local correctional facility, a fine of up to $500, or both. Voluntary and involuntary manslaughter are the labels Maryland's courts use, and deaths caused by driving are handled by separate statutes: manslaughter by vehicle or vessel (2-209), criminally negligent manslaughter by vehicle or vessel (2-210), and four impaired-driving homicide offenses (2-503 to 2-506).

Maryland has no felony classes, so each of these statutes sets its own maximum. For how other states define and grade the same conduct, see our guide to manslaughter laws by state.

Jurisdiction scope: This article covers Maryland criminal law on homicide below murder: the manslaughter penalty and provocation limits in Criminal Law 2-207, the common-law definitions of voluntary and involuntary manslaughter, manslaughter by vehicle or vessel (2-209), criminally negligent manslaughter by vehicle or vessel (2-210), homicide by motor vehicle or vessel while impaired (2-503 to 2-506), the viable-fetus provision (2-103), fleeing a police officer and leaving the scene where a death results (Transportation 21-904 and 20-102, and Natural Resources 8-724 for vessels), license revocation (Transportation 16-205), and other offenses graded by a resulting death. It does not cover murder (see how long a life sentence is in Maryland and murder sentencing guidelines), self-defense (see Maryland self-defense laws), civil lawsuits over a death (see Maryland wrongful death), or federal offenses (see the manslaughter laws hub).

What is manslaughter in Maryland?

Section 2-207 of the Criminal Law Article does not define manslaughter. It sets the penalty for the common-law crime:

"(a) A person who commits manslaughter is guilty of a felony and on conviction is subject to: (1) imprisonment not exceeding 10 years; or (2) imprisonment in a local correctional facility not exceeding 2 years or a fine not exceeding $500 or both."

The definitions come from Maryland's highest court. Maryland recognizes two common-law forms, and Title 2 contains no numbered degrees of manslaughter and no general negligent or reckless homicide offense outside the vehicle and vessel sections.

Voluntary manslaughter. In Girouard v. State, 321 Md. 532 (1991), the Court of Appeals defined it as "an intentional homicide, done in a sudden heat of passion, caused by adequate provocation, before there has been a reasonable opportunity for the passion to cool."

Involuntary manslaughter. In State v. Albrecht, 336 Md. 475 (1994), the court described it this way: "In Maryland, involuntary manslaughter is a common law felony, generally defined as an unintentional killing done without malice, (1) by doing some unlawful act endangering life but which does not amount to a felony, or (2) in negligently doing some act lawful in itself, or (3) by the negligent omission to perform a legal duty."

The main homicide offenses below murder in Maryland are:

• Manslaughter (common law, penalty in Criminal Law 2-207), covering both voluntary and involuntary manslaughter.
• Manslaughter by vehicle or vessel (2-209), a death caused by grossly negligent driving or operation.
• Criminally negligent manslaughter by vehicle or vessel (2-210), a death caused by criminally negligent driving or operation.
• Homicide by motor vehicle or vessel while under the influence of alcohol or alcohol per se (2-503), while impaired by alcohol (2-504), while impaired by drugs (2-505), and while impaired by a controlled dangerous substance (2-506).

Under Criminal Law 2-102, a prosecution "may be instituted for murder, manslaughter, or unlawful homicide, whether at common law or under this title, regardless of the time that has elapsed." For other deadlines, see Maryland statute of limitations.

Is manslaughter a felony in Maryland? Offenses and penalties

Manslaughter is a felony under 2-207(a). So are manslaughter by vehicle or vessel and all four impaired-driving homicide offenses. Criminally negligent manslaughter by vehicle or vessel is a misdemeanor on a first conviction and a felony for a person with a listed prior conviction.

Maryland does not sort crimes into felony classes, so there is no separate class-sentencing section: each statute states its own maximum, and every term in the table is a ceiling. The sections quoted here (2-207, 2-209, 2-210 and 2-503 to 2-506) state only maximum terms and fines; the repeat-offender minimums in Criminal Law 14-101 and the firearm add-on in 4-204, described below, can also apply. For how Maryland labels and sentences crimes more generally, see Maryland felony and misdemeanor classes.

Voluntary manslaughter and provocation

Girouard sets out the classic common-law test: an intentional killing, in a sudden heat of passion, caused by adequate provocation, before a reasonable opportunity for the passion to cool. The court listed the provocations Maryland had recognized as adequate: "(1) discovering one's spouse in the act of sexual intercourse with another; (2) mutual combat; (3) assault and battery." It also held that "[i]nsulting words or gestures, no matter how opprobrious, do not amount to an affray, and standing alone, do not constitute adequate provocation."

The legislature has since narrowed that list. Section 2-207(b) provides:

"(b) The discovery of one's spouse engaged in sexual intercourse with another does not constitute legally adequate provocation for the purpose of mitigating a killing from the crime of murder to voluntary manslaughter even though the killing was provoked by that discovery."

Maryland's bar on "panic" provocation claims (2-207(c))

Section 2-207(c) reads:

"(c) The discovery or perception of, or belief about, another person's race, color, national origin, sex, gender identity, sexual orientation, religious beliefs, or disability, whether or not accurate, does not constitute legally adequate provocation to mitigate a killing from the crime of murder to manslaughter."

Subsection (c) was added by 2021 Md. Laws ch. 369 (House Bill 231), effective October 1, 2021, which became law without the Governor's signature. As enacted in 2021, it covered race, color, national origin, sex, gender identity and sexual orientation; the current text also lists religious beliefs and disability, which 2024 Md. Laws ch. 377 (House Bill 1397) added effective October 1, 2024.

Self-defense and other justifications are a separate subject, covered on the Maryland self-defense laws page.

Involuntary manslaughter and gross negligence

Albrecht names three routes to involuntary manslaughter: an unlawful act endangering life that does not amount to a felony, a lawful act done negligently, and a negligent failure to perform a legal duty. For the lawful-act route, the court held that "a conviction of manslaughter will not lie on a showing of simple negligence or misadventure or carelessness but must rather be predicated upon that degree of aggravated negligence which is termed 'gross' negligence."

The court explained what gross negligence means here, quoting an earlier Court of Special Appeals decision: "the negligence necessary to support a conviction must be gross or criminal, viz., such as manifests a wanton or reckless disregard of human life." It added that whether conduct amounted to gross negligence "must be determined by the conduct itself and not by the resultant harm."

Vehicular manslaughter and DUI deaths in Maryland

Maryland has a separate ladder of statutory offenses for deaths caused by driving or operating a vehicle or vessel. The level of carelessness and whether the driver was impaired decide which one applies.

Manslaughter by vehicle or vessel (2-209)

"(b) A person may not cause the death of another as a result of the person's driving, operating, or controlling a vehicle or vessel in a grossly negligent manner. (c) A violation of this section is manslaughter by vehicle or vessel."

For this section, "vehicle includes a motor vehicle, streetcar, locomotive, engine, and train" (2-209(a)). The offense is a felony punishable by up to 10 years, a fine of up to $5,000, or both. A person who has previously been convicted under 2-209, 2-210, 2-503, 2-504, 2-505, 2-506 or 3-211 of the Criminal Law Article, or under Transportation 21-902 (Maryland's drunk and drugged driving statute), faces up to 15 years, a fine of up to $10,000, or both.

Criminally negligent manslaughter by vehicle or vessel (2-210)

Section 2-210 covers a death caused by driving, operating or controlling a vehicle or vessel "in a criminally negligent manner," and it defines that term for its own purposes:

"(c) For purposes of this section, a person acts in a criminally negligent manner with respect to a result or a circumstance when: (1) the person should be aware, but fails to perceive, that the person's conduct creates a substantial and unjustifiable risk that such a result will occur; and (2) the failure to perceive constitutes a gross deviation from the standard of care that would be exercised by a reasonable person."

Ordinary negligence is not enough: "It is not a violation of this section for a person to cause the death of another as the result of the person's driving, operating, or controlling a vehicle or vessel in a negligent manner" (2-210(d)). A first violation is a misdemeanor punishable by up to 3 years, a fine of up to $5,000, or both. With a prior conviction under 2-209, 2-210, 2-503 to 2-506, 3-211, or Transportation 21-902, it is a felony punishable by up to 5 years, a fine of up to $10,000, or both.

The difference between 2-209 and 2-210 is the degree of carelessness: grossly negligent driving is the felony with the 10-year maximum, and criminally negligent driving is the misdemeanor with the 3-year maximum.

Homicide by motor vehicle or vessel while impaired (2-503 to 2-506)

Deaths caused by impaired driving have their own four offenses. Each requires that the person caused the death "as a result of the person's negligently driving, operating, or controlling a motor vehicle or vessel" while in the listed condition:

• Under the influence of alcohol or alcohol per se (2-503): a felony, up to 5 years, a fine of up to $5,000, or both; with a listed prior conviction, up to 10 years, a fine of up to $10,000, or both. "Under the influence of alcohol per se" means an alcohol concentration of at least 0.08, as defined in Criminal Law 3-211(a)(2).
• Impaired by alcohol (2-504): a felony, up to 3 years, a fine of up to $5,000, or both; with a listed prior conviction, up to 5 years, a fine of up to $10,000, or both.
• Impaired by drugs (2-505): the person was "so far impaired by a drug, a combination of drugs, or a combination of one or more drugs and alcohol that the person cannot drive, operate, or control a motor vehicle or vessel safely." A felony, up to 5 years, a fine of up to $5,000, or both; with a listed prior conviction, up to 10 years, a fine of up to $10,000, or both. Under 2-505(d), being entitled under state law to use the drug is not a defense "unless the person was unaware that the drug, combination of drugs, or combination of one or more drugs and alcohol would make the person incapable of driving, operating, or controlling a motor vehicle or vessel in a safe manner."
• Impaired by a controlled dangerous substance (2-506): a felony, up to 5 years, a fine of up to $5,000, or both; with a listed prior conviction, up to 10 years, a fine of up to $10,000, or both. Under 2-506(d), the section "does not apply to a person who is entitled to use the controlled dangerous substance under the laws of this State."

The prior convictions that raise these penalties are listed in each section and include 2-209, 2-210, the other impaired-homicide sections, 3-211 and Transportation 21-902. A 2023 act (2023 Md. Laws ch. 552 and ch. 553, effective October 1, 2023) made certain earlier convictions for drunk or drugged operation of a vehicle or vessel, and for grossly negligent manslaughter by vehicle or vessel, count as prior convictions for the subsequent-offender penalties in Transportation 21-902 and Natural Resources 8-738. That act amended those two sections, not the homicide sections themselves.

The non-fatal companion offense, causing a life-threatening injury by negligently driving under the influence of alcohol or alcohol per se (3-211), is a misdemeanor punishable by up to 3 years, a fine of up to $5,000, or both. For DUI penalties where no one dies, see Maryland DUI laws.

License revocation

Under Transportation 16-205(b)(1), the Motor Vehicle Administration "shall revoke the license" of a person convicted of:

• homicide by a motor vehicle while under the influence of alcohol, impaired by alcohol, or impaired by drugs or a controlled dangerous substance under Criminal Law Title 2, Subtitle 5;
• drunk or drugged driving under Transportation 21-902(a), (b), (c) or (d) "that contributes to an accident that results in the death or life threatening injury of another person"; or
• failing to remain at the scene of an accident that results in the death or serious bodily injury of another person (Transportation 20-102).

No temporary license may be issued during an administrative appeal of such a revocation (16-205(b)(2)). A 2025 act (2025 Md. Laws ch. 366, Senate Bill 207, effective October 1, 2025) required these revocations for impaired driving or leaving the scene where an accident results in death or life-threatening injury, and authorized a person whose license is revoked under it, or for homicide by motor vehicle while impaired, to apply for reinstatement after a set period.

Fleeing the police and leaving the scene

A driver who commits a fleeing or eluding violation under Transportation 21-904(b)(1) or (c)(1) "that results in death of another person" violates 21-904(d)(2), punishable by up to 10 years, a fine of up to $5,000, or both (21-904(f)(3)). The section states the penalty without labeling the offense a felony or misdemeanor.

A driver who fails to remain at the scene of an accident that results in a death faces up to 5 years, a fine of up to $5,000, or both, under Transportation 20-102. A driver "who knew or reasonably should have known that the accident might result in the death of another person and death actually occurred to another person, is guilty of a felony" punishable by up to 10 years, a fine of up to $10,000, or both. See Maryland hit-and-run laws.

On the water, the operator of a vessel involved in a collision, accident or other casualty that results in a death must immediately stop as close as possible to the scene (Natural Resources 8-724(a)(2)). A violation is a misdemeanor punishable by up to 5 years, a fine of up to $5,000, or both; an operator who "knew or reasonably should have known that the collision, accident, or other casualty might result in the death of another person and death actually occurred to another person is guilty of a felony" punishable by up to 10 years, a fine of up to $10,000, or both. These vessel tiers were added by 2025 Md. Laws ch. 275 (Senate Bill 123), effective October 1, 2025.

Other homicide offenses below murder

Viable fetus (2-103). Subject to the exceptions in subsections (d) through (f), "a prosecution may be instituted for murder or manslaughter of a viable fetus" (2-103(b)). The person prosecuted must have intended to cause the death of the viable fetus, intended to cause it serious physical injury, or "wantonly or recklessly disregarded the likelihood that the person's actions would cause the death of or serious physical injury to the viable fetus" (2-103(c)). "Viable" takes its meaning from Health-General 20-209.

Other offenses graded by a resulting death

• First-degree child abuse, Criminal Law 3-601(b)(2): a felony; up to 40 years if the abuse results in the death of a victim at least 13 years old, and up to life if it results in the death of a victim under 13; up to life, at any age, after a previous conviction under the section (3-601(c)).
• Abuse or neglect of a vulnerable adult resulting in death, Criminal Law 3-604: a felony, up to 10 years, a fine of up to $10,000, or both.
• Assisting suicide, Criminal Law 3-102 and 3-104: a felony, up to 1 year, a fine of up to $10,000, or both.
• Causing the serious physical injury or death of a vulnerable individual (such as a pedestrian, cyclist or road worker) by operating a motor vehicle in violation of the Vehicle Law, Transportation 21-901.3 (created by 2021 Md. Laws ch. 165 and ch. 166, effective October 1, 2021): a fine of up to $2,000, a license suspension of at least 7 days and not more than 6 months, and up to 150 hours of community service.
• Speed contests and races, Transportation 21-1116 (rewritten by 2024 Md. Laws ch. 569 and ch. 570, effective June 1, 2024): up to 60 days, a fine of up to $1,000, or both; up to 1 year, a fine of up to $1,000, or both where the violation results in serious bodily injury. The section sets no separate tier for a death.
• Malicious or fraudulent burning resulting in the death of or serious physical injury to a firefighter, Criminal Law 6-112 (2025 Md. Laws ch. 189, effective October 1, 2025): a felony, up to 10 years.
• Failing to yield to a person lawfully riding a bicycle, EPAMD or motor scooter in a designated bike lane or shoulder, where the violation contributes to the rider's serious physical injury or death, Transportation 21-1209(d)(2) (2024 Md. Laws ch. 464, effective October 1, 2024): up to 2 months, a fine up to $2,000, or both.
• Failing to clear accumulated snow and ice from a vehicle, where the violation contributes to an accident that results in property damage or the death of or serious bodily injury to another person, Transportation 21-1135(c) (2026 Md. Laws ch. 668, effective October 1, 2026): a fine of $200 to $1,000, or $500 to $1,500 for a commercial vehicle.

Sentencing: repeat offenders, firearms and parole

Repeat crimes of violence (14-101). Criminal Law 14-101(a)(4) lists "manslaughter, except involuntary manslaughter" as a crime of violence, so it reaches voluntary manslaughter. A person convicted a second time of a crime of violence, who served a term of confinement for the prior one, must be sentenced to at least 10 years, which the court may not suspend (14-101(d)). A third conviction, after two prior separate crime-of-violence convictions and at least one term of confinement, carries at least 25 years (14-101(c)). A fourth, after three separate terms of confinement for crimes of violence, carries life without the possibility of parole (14-101(b)).

Firearm use (4-204). Using a firearm in the commission of a crime of violence or any felony, which includes manslaughter, is a separate offense under Criminal Law 4-204. In addition to the sentence for the underlying crime, it carries at least 5 and up to 20 years, and the person is not eligible for parole in less than 5 years, except as Correctional Services 4-305 provides (4-204(c)).

Parole (Correctional Services 7-301). Because voluntary manslaughter is a crime of violence under 14-101, it is a "violent crime" for parole purposes (Correctional Services 7-101(m)). A person sentenced to the Division of Correction for a violent crime committed on or after October 1, 1994 is not eligible for parole until serving the greater of one-half of the aggregate sentence for violent crimes or one-fourth of the total aggregate sentence (7-301(c)). For other sentences of 6 months or more, parole is generally considered after one-fourth of the term is served (7-301(a)).

Recent changes

• October 1, 2021: 2021 Md. Laws ch. 369 (House Bill 231) added 2-207(c), barring a victim's race, color, national origin, sex, gender identity or sexual orientation from counting as legally adequate provocation.

Leading Maryland cases

• State v. Albrecht, 336 Md. 475 (1994): involuntary manslaughter is a common-law felony; when it rests on a lawful act done negligently, the negligence must be gross, meaning "a wanton or reckless disregard of human life," judged by the conduct and not the resulting harm.
• Girouard v. State, 321 Md. 532 (1991): voluntary manslaughter is an intentional homicide in a sudden heat of passion caused by adequate provocation, before a reasonable opportunity to cool; insulting words or gestures, standing alone, are not adequate provocation.

Frequently Asked Questions

Is manslaughter a felony in Maryland?

Yes. Under Md. Code, Criminal Law 2-207(a), a person who commits manslaughter is guilty of a felony. Manslaughter by vehicle or vessel and the four impaired-driving homicide offenses are also felonies; criminally negligent manslaughter by vehicle or vessel (2-210) is a misdemeanor unless the person has a listed prior conviction.

What is the sentence for manslaughter in Maryland?

Up to 10 years in prison, or alternatively up to 2 years in a local correctional facility, a fine of up to $500, or both (Criminal Law 2-207(a)). Section 2-207 sets maximums only, but for voluntary manslaughter the repeat-offender minimums in Criminal Law 14-101 and the one-half parole rule for violent crimes can apply, and using a firearm adds a separate 5-to-20-year term under 4-204.

What is the difference between voluntary and involuntary manslaughter in Maryland?

Both are common-law forms. Voluntary manslaughter is an intentional killing in a sudden heat of passion caused by adequate provocation, before a reasonable opportunity to cool (Girouard v. State). Involuntary manslaughter is an unintentional killing without malice by an unlawful act endangering life that does not amount to a felony, a grossly negligent lawful act, or a negligent failure to perform a legal duty (State v. Albrecht).

What is vehicular manslaughter in Maryland?

Manslaughter by vehicle or vessel under Criminal Law 2-209 is causing a death by driving, operating or controlling a vehicle or vessel in a grossly negligent manner. It is a felony punishable by up to 10 years, a fine of up to $5,000, or both, and up to 15 years with a listed prior conviction.

What is the penalty for a DUI death in Maryland?

Homicide by motor vehicle or vessel while under the influence of alcohol or alcohol per se (Criminal Law 2-503) is a felony punishable by up to 5 years, a fine of up to $5,000, or both, or up to 10 years with a listed prior conviction. The impaired-by-alcohol offense (2-504) carries up to 3 years, and the drug and controlled dangerous substance offenses (2-505, 2-506) up to 5 years. License revocation is mandatory under Transportation 16-205(b).

Can provocation reduce murder to manslaughter in Maryland?

Under the common law described in Girouard v. State, a killing in a sudden heat of passion caused by adequate provocation is voluntary manslaughter; insulting words alone are not adequate. Criminal Law 2-207(b) and (c) exclude discovering a spouse's adultery and a victim's race, color, national origin, sex, gender identity, sexual orientation, religious beliefs or disability as adequate provocation.

Is there a time limit to prosecute manslaughter in Maryland?

No. Criminal Law 2-102 allows a prosecution for murder, manslaughter or unlawful homicide regardless of the time that has elapsed between the act or omission that caused the death and the death.
