The Texas Intoxication Assault law requires the state to prove that you accidentally or mistakenly injured someone while committing any of the other intoxication offenses such as Driving While Intoxicated, Boating While Intoxicated, or Flying While Intoxicated.

Intoxication Assault is a serious crime that escalates a drunk driving or driving under the influence charge to a felony. The state most often prosecutes Intoxication Assault when police believe a person is drunk or on drugs while driving and gets into a car accident. You can be charged with Intoxication Assault whether you injure a passenger in your own vehicle or someone in another vehicle. Learn more about the underlying Texas Driving While Intoxicated law.

The state must prove several elements of the Intoxication Assault law in order to obtain a conviction. Among the most frequently contested are: whether you were intoxicated under the law, whether your intoxication was the cause of the injury, and whether you were the person operating the vehicle.

The Texas legislature codified this criminal offense in Texas Penal Code Section 49.07. The law was not updated in 2023. In fact, this law has not been amended since 2007.

The Penal Code classifies the Texas Intoxication Assault law under Title 10 “Offenses Against Public Health, Safety, And Morals,” Chapter 49 “Intoxication and Alcoholic Beverage Offenses.” Learn more about the Texas offense of Intoxication Assault below.

What is the current Texas law about Intoxication Assault?

The current Texas law defines the offense of Intoxication Assault in Penal Code Section §49.07 as follows:[1]

(a) A person commits an offense if the person, by accident or mistake:

(1) while operating an aircraft, watercraft, or amusement ride while intoxicated, or while operating a motor vehicle in a public place while intoxicated, by reason of that intoxication causes serious bodily injury to another; or

(2) as a result of assembling a mobile amusement ride while intoxicated causes serious bodily injury to another.

The Intoxication Assault statute makes it clear that the state does not have to prove you injured someone intentionally to charge you with Intoxication Assault in Texas. You can be charged with Intoxication Assault for injuring someone by accident or mistake.

What constitutes being intoxicated?

Intoxication means being under the influence of alcohol or on drugs to the point where you no longer have normal use of your mental or physical functions. The state can prove intoxication by showing that you had a blood alcohol concentration of .08 or more or that you lost the “normal” use of your mental or physical faculties due to the introduction of any substance into your body. Note that you are “intoxicated” under Texas Law even if you were prescribed the medicine or it was over the counter or the substance is otherwise entirely legal.

What type of vehicles does the Intoxication Assault statute include?

For Intoxication Assault offenses requiring the operation of a motor vehicle, the law does not include vehicles that travel on a fixed track,[2] like a train.

What type of injury does Intoxication Assault involve? What does serious bodily injury mean?
