Intoxication Assault Under the Texas Penal Code: Felony Penalties

Intoxication assault under the Texas Penal Code is a felony offense defined in § 49.07: causing serious bodily injury to another person by accident or mistake while operating a motor vehicle in a public place, or operating a boat, aircraft, or amusement ride anywhere, while intoxicated.¹ A standard conviction is a third-degree felony punishable by 2 to 10 years in prison and a fine of up to $10,000. The charge can rise to a second-degree or first-degree felony depending on who was hurt and how badly.

What the State Has to Prove

Prosecutors must establish three things: that you were intoxicated, that you were operating a vehicle (or boat, aircraft, or amusement ride) covered by the statute, and that your intoxication caused serious bodily injury to someone else by accident or mistake.¹ The “by accident or mistake” language is what separates this charge from intentional violence. The state does not have to show you meant to hurt anyone.

“Intoxicated” has two definitions under § 49.01. One is lacking the normal use of mental or physical faculties because of alcohol, a controlled substance, a drug, or a combination. The other is a blood alcohol concentration of 0.08 or more.² Only one has to be proven. A BAC under 0.08 does not defeat the charge if other evidence shows impairment.

For motor vehicles, the offense must occur in a “public place.” Texas courts read that term broadly to cover streets, highways, parking lots, and any area the public can access.

What Counts as Serious Bodily Injury

The word “serious” is the dividing line between intoxication assault and a regular DWI. Ordinary bodily injury means any physical pain, illness, or impairment of physical condition.³ Serious bodily injury under § 49.07(b) is a much higher threshold. It covers injury that creates a substantial risk of death, causes serious permanent disfigurement, or results in protracted loss or impairment of a bodily function.¹

In practice, medical records and expert testimony decide whether a given injury clears the bar. A broken arm from a minor collision usually will not. A shattered pelvis requiring multiple surgeries, or a brain injury with lasting cognitive effects, usually will. If the injury does not meet the serious threshold, intoxication assault does not apply, though DWI charges can still follow.

Standard Penalties

A base-level intoxication assault is a third-degree felony under § 49.07(c), which means 2 to 10 years in the Texas Department of Criminal Justice and a possible fine of up to $10,000.⁴ Court costs, mandatory program fees, and restitution come on top of the fine.

Restitution to the Victim

Under Article 42.037 of the Code of Criminal Procedure, the sentencing court can order a defendant to pay the victim directly for medical bills, rehabilitation costs, lost income, and other losses tied to the offense.⁵ If the court orders no restitution or only partial restitution, the judge must put the reasons on the record. In serious-injury cases, restitution often dwarfs the statutory fine.

Probation and Ignition Interlock

Community supervision is possible, but the conditions are tight. A court placing someone on supervision for an intoxication offense can require an ignition interlock device on any vehicle the defendant drives. The interlock is mandatory when the defendant’s BAC tested at 0.15 or above, when there is a prior intoxication conviction, or when the defendant was under 21 at the time of the offense.⁶ It has to stay installed for at least half the supervision period.

When the Felony Level Goes Up

Texas Penal Code § 49.09 raises the classification when certain victims are hurt or when the injury takes a particular form.

Injuring a firefighter or emergency medical services worker performing official duties bumps the charge to a second-degree felony, which carries 2 to 20 years in prison and a fine of up to $10,000.⁷

Injuring a peace officer or judge on duty raises the charge to a first-degree felony.⁸ A first-degree felony carries 5 to 99 years (or life) and a fine of up to $10,000. The ceiling jumps from 10 years to 99.

A separate enhancement under § 49.09(b-4) applies when the victim suffers a traumatic brain injury that results in a persistent vegetative state. That makes the offense a second-degree felony regardless of the victim’s occupation, with the same 2-to-20-year range.⁸

Driver’s License Consequences

A conviction triggers a driver’s license suspension separate from the criminal sentence. Defendants under 21 face an automatic one-year suspension on conviction for intoxication assault, and the suspension can extend past a year if a required alcohol education program is not completed.⁹ Adult defendants also face suspension, with the length depending on prior history and any administrative suspension already running from the arrest.

That administrative suspension is a parallel track. Under the Administrative License Revocation program, your license can be suspended shortly after arrest if you fail or refuse a breath or blood test, long before any trial.

After a suspension, an occupational driver’s license may be available for limited driving to work, school, and essential household tasks. When the suspension stems from an intoxication conviction, the application has to be filed in the court of conviction rather than in a justice of the peace court, and an ignition interlock device is typically required as a condition.⁶

Intoxication Assault vs. Intoxication Manslaughter

The dividing line is whether the victim survives. Intoxication manslaughter under § 49.08 applies when impaired operation causes someone’s death. It starts as a second-degree felony with a 2-to-20-year range, one tier above standard intoxication assault.⁸ If a victim initially charged as an assault victim later dies from the injuries, the state can upgrade the charge.

The Full Financial Picture

The $10,000 statutory fine is often the smallest money consequence. Court costs, mandatory alcohol evaluation and treatment, probation supervision fees, and the monthly cost of the ignition interlock (typically over $100 per month for the length of the requirement) stack up over the life of the case. Restitution for surgery, hospitalization, and long-term rehabilitation can run into six figures. A felony conviction also creates lasting barriers to employment, professional licensing, housing, and firearm ownership that carry their own cost for years after the sentence ends.
