Intoxication Assault Lawyer In Conroe, TX
Intoxication assault is the charge when a DWI crash leaves someone seriously hurt, and no intent has to be proven. In Montgomery County the District Attorney's Office has its own Vehicular Crimes Unit, so this page covers the elements, the penalty levels, the defenses and the first steps.
What Is Intoxication Assault In Texas?
Intoxication assault is a DWI that causes serious bodily injury to another person. Texas Penal Code § 49.07 makes it a third degree felony, with higher levels for certain victims. The state does not have to prove intent, but it must prove that the injury resulted from the intoxication. Serious bodily injury is defined in Penal Code § 1.07.
Understanding Texas Law
How Does Texas Law Define Intoxication Assault?
Penal Code § 49.07 makes it a third degree felony to cause serious bodily injury to another person, by accident or mistake, while operating a motor vehicle in a public place while intoxicated. The same section reaches aircraft, watercraft and amusement rides.
No intent is part of the offense. Penal Code § 49.11 removes the mental state for intoxication crimes, so the state does not have to show that the driver meant, knew or recklessly risked anything.
Two questions stay open for the state. Was the harm serious bodily injury as the Penal Code defines it? And did the intoxication cause it? Under § 6.04, a driver is not responsible when another cause was clearly sufficient by itself and the driver's conduct was clearly insufficient.
What the state has to prove under § 49.07:
- Operating a motor vehicle in a public place, or an aircraft, watercraft or amusement ride
- While intoxicated, by a 0.08 concentration or loss of normal faculties
- Serious bodily injury to another person
- Caused by reason of the intoxication
"Serious bodily injury" has a narrow meaning in § 1.07. A wrist fracture that heals on schedule, or a cut that leaves no lasting mark, raises the question of whether the definition is met. The medical records answer it, not the scene photographs.
If the injured person dies, the charge becomes intoxication manslaughter. Where intoxication is not alleged, a crash injury can be charged as vehicular assault under other statutes.

Penalties And Consequences
What Are The Penalties For Intoxication Assault In Texas?
The base level is a third degree felony. Section 49.09 raises it for particular victims and injuries, and several procedural rules make these cases heavier than the range alone suggests. These are statutory limits, not predictions.
Code of Criminal Procedure art. 42A.401.
- Base level
- Third degree felony: two to ten years in prison, fine up to $10,000.
- Second degree
- When the injury is a traumatic brain injury resulting in a persistent vegetative state, or the injured person is a firefighter or EMS worker on duty.
- First degree
- Five to ninety-nine years or life, when the injured person is a peace officer or judge on duty.
- Community supervision
- Available, with at least 30 days in county jail as a condition under Code of Criminal Procedure art. 42A.401.
- Deferred adjudication
- Barred by art. 42A.102.
- Several injured people
- Sentences can be ordered to run consecutively under Penal Code § 3.03(b).
- Bond
- An ignition interlock under art. 17.441 unless the magistrate finds it not in the interest of justice.
A vehicle can be found to be a deadly weapon in an intoxication assault case. The effect of that finding on probation and parole is set out on the 3G offenses page.

Possible Defenses
How Can Intoxication Assault Be Defended?
When prosecutors and investigators respond to the scene, the state's account of the crash is being built from the first hour. Measurements, photographs, witness statements and vehicle data are all collected then. The same material can be examined from the other side, because each piece has a method behind it. No result can be promised.
- Reconstruction: scene measurements, point of impact and speed calculations
- Event data recorders: what each vehicle's module recorded, and what it did not
- Medicine: whether the injury meets the § 1.07 definition, and for how long
- Blood: a warrant or claimed exception, the timing of the draw and the lab analysis
Causation and timing are the questions most often in dispute.
The other driver's speed, a failed signal, a vehicle defect or the road itself can each bear on whether intoxication caused the injury. Section 6.04 is where that question starts.
Timing matters for the blood too. A hospital draw can come hours after the crash, and a hospital result is not the same as a forensic result. In Montgomery County, a crash draw can also follow a warrant, and that warrant can be challenged on the affidavit, the draw and the lab work. The DWI court process page covers how those challenges are raised.

Was It Serious Bodily Injury?
Do the medical records show an injury inside the statutory definition?
Did Intoxication Cause It?
Could another driver, a signal failure or road conditions explain the crash?
Was The Blood Draw Lawful?
A hospital or roadside draw needs a warrant, consent or an exception, and the result can be tested.
What Does The Data Recorder Show?
Speed, braking and steering data can support or contradict the report.
Who Was Driving?
In some crashes, who sat behind the wheel is itself disputed.
Is The Charge Level Right?
Does the victim or the injury actually support a higher felony level?

Common Questions
Intoxication Assault Questions People In Conroe Ask
What does intoxication assault mean in Conroe, TX?
Under Texas Penal Code § 49.07, intoxication assault is causing serious bodily injury to another person, by accident or mistake, while operating a motor vehicle in a public place while intoxicated. The statute also covers aircraft, watercraft and amusement rides. The injury has to be caused by the intoxication, and the state does not have to prove any intent to injure.
Who investigates an intoxication assault crash in Montgomery County?
The first response comes from the agency with jurisdiction over the road, which could be a city police department, the Sheriff's Office, a constable precinct or DPS. The Montgomery County District Attorney's Office also runs a Vehicular Crimes Unit of prosecutors and investigators that responds directly to crash scenes and handles intoxication assault and intoxication manslaughter cases.
What injury is serious enough for intoxication assault in Montgomery County?
Penal Code § 1.07 defines serious bodily injury as injury that creates a substantial risk of death, or that causes death, serious permanent disfigurement, or protracted loss or impairment of the function of a bodily member or organ. An injury that falls short of that definition cannot support intoxication assault, although a DWI charge for the same driving can remain.
What sentence can intoxication assault carry in Conroe?
At its base level, intoxication assault is a third degree felony: two to ten years in prison and a fine up to $10,000. It rises to a second degree felony for a traumatic brain injury that results in a persistent vegetative state, or an injured on-duty firefighter or EMS worker, and to a first degree felony when the injured person is an on-duty peace officer or judge.
Can intoxication assault sentences be stacked in Montgomery County?
Penal Code § 3.03(b) allows the court to order sentences for intoxication assault and intoxication manslaughter from the same criminal episode to run one after another rather than at the same time. That matters when a single crash injures or kills more than one person. Whether any sentences are stacked is a decision for the court.
