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 Maryland, the criminal offense similar to what is described as 'intoxication assault' in other jurisdictions is typically charged under DUI (driving under the influence) or DWI (driving while impaired) laws when serious bodily injury occurs as a result of the impaired driving. Maryland does not use the term 'intoxication assault,' but the state's Transportation Article § 21-902 and Criminal Law Article § 2-209 address situations where an individual operates a vehicle under the influence of alcohol or drugs and causes life-threatening injury or death to another person. Such offenses are considered felonies and are subject to severe penalties, including substantial fines and imprisonment. The specific charges and penalties can vary depending on the circumstances of the case, such as the level of intoxication and the severity of the injuries caused. It is important for individuals facing such charges to consult with an attorney who is knowledgeable about Maryland's DUI and DWI laws and the potential consequences of a conviction.
