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 Wyoming, the relevant offense for a situation where a person operates a motor vehicle while intoxicated and causes an accident resulting in the death of another person is known as 'vehicular homicide.' Wyoming does not use the term 'intoxication manslaughter,' which is used in some other states. Under Wyoming Statutes § 6-2-106, vehicular homicide is defined as the unlawful killing of a human being by the operation of a motor vehicle in a reckless manner, and it is a felony. If the operator is under the influence of alcohol or controlled substances and this contributes to the reckless nature of the driving, it can be grounds for vehicular homicide charges. The penalties for vehicular homicide in Wyoming can include imprisonment, fines, and the revocation of driving privileges. It is important for individuals facing such serious charges to consult with an attorney who is knowledgeable in Wyoming's criminal law and can provide legal representation.
