Intoxication assault in Texas is a third-degree felony under Penal Code Section 49.07, filed when a driver causes serious bodily injury to another person while intoxicated. A conviction carries two to ten years in prison and a fine up to $10,000.1State of Texas. Texas Penal Code 49.07 – Intoxication Assault The statute also reaches operators of watercraft, aircraft, and amusement rides. Prosecutors do not have to prove you meant to hurt anyone. The decision to drive while impaired is the wrongful act, and the injuries that follow are treated as foreseeable consequences of that choice.
What the State Has to Prove
Three elements carry a conviction: you operated a motor vehicle in a public place (or an aircraft, watercraft, or amusement ride anywhere), you were intoxicated, and your intoxication caused serious bodily injury to another person.1State of Texas. Texas Penal Code 49.07 – Intoxication Assault
Texas defines “intoxicated” two ways, and the state only has to prove one. The first is a blood alcohol concentration of 0.08 or higher. The second is not having the normal use of your mental or physical faculties because of alcohol, a controlled substance, a drug, a dangerous drug, or any combination of them.2State of Texas. Texas Penal Code 49.01 – Definitions That second route matters. A BAC below 0.08 is not a defense if prosecutors can show impairment from prescription medication, marijuana, or a mix of substances.
The words “by accident or mistake” sit inside the statute itself. That is what separates intoxication assault from aggravated assault. You did not have to want the crash or the injury. The theory is that choosing to drive while impaired was reckless enough to make you answerable for what happened next.1State of Texas. Texas Penal Code 49.07 – Intoxication Assault Cases usually turn on the causal link between impairment and collision, built from blood test results, breath tests, and the arresting officer’s observations of field sobriety performance.
What Counts as Serious Bodily Injury
The whole severity of the charge hangs on this one definition. Serious bodily injury under Penal Code Section 1.07 means an injury that creates a substantial risk of death, causes death, results in serious permanent disfigurement, or produces protracted loss or impairment of the function of any bodily member or organ.3State of Texas. Texas Penal Code 1.07 – Definitions This is a much higher bar than ordinary bodily injury, which can mean nothing more than physical pain.
In real cases it covers a fractured skull, internal bleeding that needs emergency surgery, a shattered pelvis that limits mobility for months, deep facial scarring, loss of a limb, vision loss in one eye, or nerve damage that prevents gripping. The common thread is that the injury either threatened the victim’s life or permanently changed their body.
Treating physicians usually testify about surgeries, prognosis, and whether the injury carried a genuine risk of death. Defense attorneys often attack this element directly, arguing that painful injuries still fell short of the “serious” threshold. On a borderline injury, like a broken arm that heals cleanly, that distinction can be the difference between a felony and a lesser charge.
The Standard Prison Range
A standard intoxication assault conviction is a third-degree felony punishable by two to ten years in the Texas Department of Criminal Justice, plus a fine up to $10,000.4State of Texas. Texas Penal Code 12.34 – Third Degree Felony Punishment
Where a judge lands inside that range depends on the facts. BAC level, severity of the injuries, whether children were in the vehicle, and prior record all pull the sentence one way or the other. A first-time offender who caused a broken leg in a low-speed crash may draw something near the minimum. A defendant with a BAC twice the legal limit who left a victim in a wheelchair faces the upper end.
When the Charge Is Enhanced
Certain facts push intoxication assault above the third-degree baseline, and the jumps are steep. Section 49.09 sets out three tiers.
- If the victim was a firefighter or emergency medical services worker in the actual discharge of an official duty, the offense becomes a second-degree felony, carrying two to twenty years in prison and a fine up to $10,000.5State of Texas. Texas Penal Code 49.09 – Enhanced Offenses and Penalties6State of Texas. Texas Penal Code 12.33 – Second Degree Felony Punishment
- If the victim was a peace officer or judge in the actual discharge of an official duty, the offense becomes a first-degree felony, punishable by five to ninety-nine years or life.5State of Texas. Texas Penal Code 49.09 – Enhanced Offenses and Penalties
- If the injury caused a traumatic brain injury that put the victim in a persistent vegetative state, the offense is a second-degree felony regardless of the victim’s occupation.5State of Texas. Texas Penal Code 49.09 – Enhanced Offenses and Penalties
The split between firefighter/EMS and peace officer/judge is enormous in practice. Injuring an on-duty officer who pulled over to help at a crash scene is a first-degree felony with a five-year mandatory minimum. Injuring a paramedic responding to the same scene is a second-degree felony with a two-year minimum. The enhancement only applies when the victim was actually on duty. An off-duty officer or firefighter at the scene in a personal capacity does not trigger it.
Probation and the Ignition Interlock
Texas law allows judges to grant community supervision instead of a full prison sentence, but the conditions attached to an intoxication assault probation are tighter than standard felony probation.
An ignition interlock device on any vehicle you own or regularly drive is one of them. The court can impose it as a discretionary condition in any case, and it becomes mandatory if your BAC was 0.15 or higher at the time of the offense, if you have a prior intoxication conviction, or if you were under 21.7State of Texas. Texas Code of Criminal Procedure Art. 42A.408 It must be installed within 30 days of conviction unless the court finds in writing that requiring it would not serve the interests of justice. You pay for the device yourself. You cannot drive any vehicle without one.
Violating a condition of supervision, whether missing a check-in, failing a drug test, or driving without the interlock, can bring revocation. If supervision is revoked, the judge can impose the original prison sentence in full.
What Happens to Your License
A conviction brings a court-ordered driver’s license suspension of 180 days to two years.8Texas Department of Public Safety. Alcohol Related Laws – Driver License Enforcement Actions It runs alongside any prison or probation term and can outlast a short community supervision sentence, which catches people off guard when they think they are finished with the court.
An occupational driver’s license lets you drive to work, school, and essential household obligations during the suspension. Getting one requires SR-22 high-risk insurance, an ignition interlock device, and proof to a judge that you have an essential need to drive. A prior intoxication conviction within the preceding five years delays the ODL from taking effect until 180 days into the suspension. A second or further prior pushes that waiting period to 365 days. Even with an ODL, you cannot drive as part of your work duties, and you have to carry the court order and a driving log at all times.
If the Victim Dies
When a victim dies from crash injuries, the charge is not intoxication assault but intoxication manslaughter under Section 49.08. The elements match — operating a vehicle while intoxicated and causing harm by accident or mistake — but the offense is a second-degree felony carrying two to twenty years.9State of Texas. Texas Penal Code 49.08 – Intoxication Manslaughter If the person killed was an on-duty peace officer, judge, firefighter, or EMS worker, it rises to a first-degree felony.5State of Texas. Texas Penal Code 49.09 – Enhanced Offenses and Penalties
This matters when a victim is alive at charging but deteriorates later. Prosecutors can and do upgrade from intoxication assault to intoxication manslaughter if the victim dies from crash-related injuries. The same evidence supports both, so your exposure can change based on the victim’s medical course.
Consequences That Outlast the Sentence
Several consequences of a felony intoxication assault conviction do not end when the sentence does.
A commercial driver’s license is one. Under federal rules, a conviction for operating any vehicle under the influence counts as a major disqualifying offense, not just a conviction in a commercial vehicle. A first offense disqualifies you from holding a CDL for one year, or three years if you were transporting hazardous materials. A second major offense means lifetime disqualification. For a driver whose livelihood depends on the CDL, a single intoxication assault conviction can end the career.
Professional licenses are another. Healthcare, law, education, and finance boards typically require disclosure of felony convictions, and a felony involving intoxication and bodily injury is the kind of conduct that triggers disciplinary review. Outcomes range from required monitoring programs to license revocation, depending on the profession and the board.
International travel gets complicated too. Canada treats impaired driving as a serious criminal offense and routinely denies entry to U.S. citizens with DUI-related convictions, including felony intoxication assault. Border officers have access to the FBI criminal database and can flag a conviction when you present your passport. Entering Canada after a conviction usually requires a Temporary Resident Permit or, once five years have passed since you finished the entire sentence, an application for Criminal Rehabilitation that forgives the conviction for entry purposes.
Then there are the ordinary ones: a felony record that makes housing harder, loss of firearm rights under federal law, much higher insurance premiums once you can drive again, and the SR-22 high-risk filing most insurers require for years. The prison or probation term has an end date. Many of these do not.
