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 Arizona, the criminal offense similar to what is described as 'intoxication assault' in other jurisdictions is typically referred to as 'Aggravated Assault' under Arizona Revised Statutes (ARS) § 13-1204 when it involves driving under the influence (DUI). If a person operates a motor vehicle while intoxicated and causes an accident that results in serious physical injury to another person, they can be charged with Aggravated Assault, which is a felony. The specific charge and potential penalties can vary depending on the circumstances, such as the severity of the injury and the level of the defendant's impairment. Aggravated Assault due to DUI causing serious physical injury is often charged as a class 3 felony, which can result in significant penalties, including prison time, fines, and a revocation of driving privileges. It's important to note that Arizona has strict DUI laws, and any DUI incident that results in injury can lead to severe legal consequences.
