If a person operates a motor vehicle while intoxicated and negligently causes an accident that results in the death of another person, the operator may be charged with the criminal offense of intoxication manslaughter.

Some states have a broader definition of the criminal offense of intoxication manslaughter and may charge an intoxicated person who negligently causes the death of another person while operating a motor vehicle, an aircraft, a watercraft, or an amusement ride with the crime of intoxication manslaughter. Intoxication manslaughter is a felony offense and may be punished by significant jail or prison time.

Laws vary from state to state, and some states have criminal offenses such as vehicular manslaughter or vehicular homicide, as provided by the state’s statutes, and may charge an intoxicated person who negligently causes the death of another motorist with such a crime.

Intoxication manslaughter laws are generally located in a state's statutes—often in the penal or criminal code.

In Mississippi, the relevant offense for a situation where a person operates a motor vehicle while intoxicated and causes an accident that results in the death of another person is known as 'DUI Homicide' or 'DUI Manslaughter.' Under Mississippi law, specifically Section 63-11-30(5) of the Mississippi Code, if a person operates a vehicle while under the influence of alcohol or drugs and as a result negligently causes the death of another person, they can be charged with this felony offense. The penalties for DUI Manslaughter in Mississippi are severe and can include significant fines and imprisonment. It's important to note that Mississippi law does not use the term 'intoxication manslaughter,' which might be found in other states' statutes. Instead, the state uses its own legal terminology and provisions for such offenses. The exact penalties and legal proceedings can be complex and vary depending on the specific circumstances of the case, so consulting with an attorney for detailed legal advice is recommended for anyone involved in such a situation.
