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 Utah, if a person operates a motor vehicle while under the influence of alcohol or drugs and causes an accident that results in the death of another person, they may be charged with the criminal offense of Automobile Homicide, which is similar to what some states refer to as intoxication manslaughter. Under Utah Code Section 76-5-207, Automobile Homicide is a second-degree felony if the driver was found to be negligently operating the vehicle while intoxicated. This charge can be elevated to a first-degree felony if the driver has a prior conviction for certain offenses. The penalties for Automobile Homicide in Utah can include significant prison time, fines, and a suspension of the driver's license. It's important to note that Utah's laws are specific to motor vehicles and do not necessarily include other types of vehicles such as aircraft, watercraft, or amusement rides, which may be covered under different statutes or not at all.
