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 North Dakota, the criminal offense similar to intoxication assault is addressed under DUI (Driving Under the Influence) laws. When a person operates a motor vehicle while under the influence of alcohol or drugs and causes an accident that results in serious bodily injury to another, it can lead to severe penalties. North Dakota Century Code (NDCC) 39-08-01 outlines the DUI laws, and while there isn't a specific statute titled 'intoxication assault,' causing serious injury while DUI can enhance the charges and penalties. This can include felony charges, which carry heavier fines and longer imprisonment. The exact penalties would depend on the circumstances of the case, including the severity of the injuries caused, the level of intoxication, and the individual's prior DUI history. It's important to note that North Dakota may not use the term 'intoxication assault,' but the legal consequences of causing serious bodily injury while intoxicated and operating a vehicle are similarly severe.
