A person commits the criminal offense of intoxication assault if the person operates a motor vehicle while intoxicated and causes an accident that results in the serious bodily injury of another person.

Some states have a broader definition of intoxication assault and may charge an intoxicated person who negligently causes serious bodily injury to another person while operating a motor vehicle, an aircraft, a watercraft, or an amusement ride with the crime of intoxication assault.

Intoxication assault is a felony offense and may be punished by significant jail or prison time. Intoxication assault laws are generally located in a state's statutes—often in the penal or criminal code.

In Nevada, the crime of causing serious bodily injury to another person as a result of operating a vehicle while under the influence of alcohol or a controlled substance is typically referred to as DUI causing injury or death. Under Nevada Revised Statutes (NRS) 484C.430, a person who is in actual physical control of a vehicle on a highway or on premises to which the public has access and who is under the influence of intoxicating liquor or a controlled or prohibited substance, and who proximately causes substantial bodily harm or death to another person through an act or omission that constitutes simple negligence, commits a category B felony. This offense is punishable by a term of imprisonment, fines, and the suspension of the driver's license. The specific penalties can vary based on the circumstances of the case and the offender's prior history with similar offenses. It is important to note that Nevada law does not limit this offense to motor vehicles but can also apply to aircraft, watercraft, or any other vehicle.
