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 Louisiana, the crime of operating a vehicle while intoxicated and causing serious bodily injury to another person is known as 'Vehicular Negligent Injuring' and is covered under Louisiana Revised Statutes Title 14:39.1. This statute states that when a person operates any vehicle negligently and causes serious bodily injury to another person while under the influence of alcoholic beverages or any other substance which impairs driving ability, they commit the offense of vehicular negligent injuring. This offense is a felony and can result in penalties including fines and imprisonment. The severity of the punishment can vary depending on the circumstances of the case, such as the level of negligence and the degree of injury caused. It's important to note that Louisiana law may differ from other states in terms of the specific terminology and the scope of vehicles or circumstances covered under its intoxication assault equivalent statutes.
