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 Mississippi, the crime of causing serious bodily injury to another person while driving under the influence is typically referred to as 'Aggravated DUI.' Under Mississippi Code Section 63-11-30(5), a person will be charged with Aggravated DUI if they operate a motor vehicle while under the influence of alcohol or drugs and, as a result, cause an accident that leads to the death or disfigurement of another person. This offense is a felony and carries severe penalties, including fines and imprisonment. The specific penalties can vary based on the circumstances of the case and the offender's prior DUI history. It's important to note that Mississippi law focuses on motor vehicle operation for this offense and does not explicitly mention aircraft, watercraft, or amusement rides in the context of Aggravated DUI.
