What Is Intoxication Assault in Texas?
Intoxication assault is the offense under §49.07 of causing serious bodily injury to another person while operating a motor vehicle, watercraft, aircraft, or amusement ride while intoxicated. It is a third-degree felony — one of several ways an ordinary DWI becomes a felony DWI in Texas. The sentence range is 2 to 10 years in prison. The maximum fine is $10,000. License suspension of 180 days to 2 years also applies upon conviction. An intoxication assault lawyer Houston clients call after a hospital blood draw begins the causation review immediately, before charges are even filed.
Intoxication assault requires an injured survivor, which sets it apart from Texas's other felony-DWI scenarios. A standard DWI involves no injury element at all. A DWI with a child passenger is a felony purely because of who was in the car, regardless of injury. And if the injured person dies, the charge is no longer intoxication assault at all — it becomes intoxicated manslaughter, a second-degree felony. An intoxication assault lawyer Houston clients hire confirms which of these categories actually fits the facts before assuming the higher or lower charge automatically applies.
The state must prove four elements beyond a reasonable doubt: (1) you were intoxicated, (2) while operating a vehicle or vessel, (3) you caused an accident, and (4) that accident caused serious bodily injury to another person. Each element is independently challengeable — and Herman challenges all four simultaneously from the first day of representation. Breaking the case into these four elements is the standard approach an intoxication assault lawyer Houston clients trust uses to identify the weakest link in the state's proof.
Serious bodily injury is defined under Texas Penal Code §1.07(a)(46) as injury creating a substantial risk of death, permanent disfigurement, or protracted loss or impairment of any body part or organ. Not every injury meets this threshold. Broken bones and lacerations that heal fully are frequently contested. Herman retains independent medical experts to evaluate whether the injury legally qualifies — because a successful challenge reduces the charge to a misdemeanor DWI. Getting an independent medical opinion early is a step every intoxication assault lawyer Houston families rely on takes before the state's expert is ever deposed.
When Does Intoxication Assault Become a 2nd Degree Felony in Texas?
The charge elevates to a second-degree felony (2–20 years) under §49.09(b-2) when the victim is a peace officer, firefighter, emergency medical personnel, or certain other protected persons acting in the course of their official duties at the time of the accident. Herman examines whether the victim actually meets the statutory definition of a protected person and whether they were performing official duties — because these requirements have specific legal criteria that are not always satisfied. An intoxication assault lawyer Houston clients hire for an enhanced charge reviews the victim's duty status and paperwork line by line before conceding the enhancement applies.
What Defense Strategies Does an Intoxication Assault Lawyer in Houston Use?
Causation is a required element of §49.07 — intoxication must have caused the accident, not merely been present at the scene. Other driver negligence, road defects, missing signage, and poor visibility can independently cause crashes. An intoxication assault lawyer in Houston retains certified accident reconstructionists who analyze crash physics, event data recorder data, skid marks, and impact angles to establish the true cause of the collision. This crash-physics analysis is central to the strategy any intoxication assault lawyer Houston clients hire builds around the causation element.
Blood draws in §49.07 cases are typically taken at the hospital during medical treatment — hours after the crash. The BAC at the time of the hospital draw may differ significantly from the BAC at the time of driving. An intoxication assault lawyer Houston clients hire challenges the retrograde extrapolation methodology, chain of custody, sample preservation, and lab procedures used to establish BAC at the moment of the offense.
An intoxication assault lawyer in Houston retains independent medical experts to review injury records, imaging, and treatment documentation. Their testimony evaluates whether the injury meets the legal standard of serious bodily injury under §1.07(a)(46). A successful challenge eliminates the felony enhancement and reduces the charge to a misdemeanor DWI — with entirely different sentencing consequences. Because that reduction changes the entire trajectory of the case, an intoxication assault lawyer Houston families trust treats the injury classification fight as a top priority.
Blood test evidence in §49.07 cases is frequently collected at the hospital — sometimes hours after the crash. An intoxication assault lawyer Houston clients trust takes an approach to challenging these results that is detailed on the breath and blood test defense page. When the accident victim dies rather than suffers serious bodily injury, the charge becomes intoxicated manslaughter under §49.08 — a second-degree felony carrying 2 to 20 years in prison.
Intoxication Assault Lawyer Houston — Questions
Yes — if the injury does not legally qualify as serious bodily injury under §1.07(a)(46), the felony enhancement does not apply and the charge must be reduced to a misdemeanor DWI. An intoxication assault lawyer in Houston challenges injury classification in every §49.07 case and retains independent medical experts to provide testimony supporting charge reduction when the evidence permits. An intoxication assault lawyer Houston clients hire for this kind of challenge often brings in a treating-physician rebuttal expert early in the case.
Yes — community supervision is available for §49.07 intoxication assault, unlike §49.08 intoxicated manslaughter where probation is prohibited for motor vehicle offenses. An intoxication assault lawyer Houston clients call negotiates for probation by documenting cooperation history, clean prior record, rehabilitation steps taken, and the specific circumstances of the accident. Probation availability makes the §49.07 versus §49.08 distinction critical to establish early in the defense.
Third-degree §49.07 intoxication assault carries 2 to 10 years in prison and a fine up to $10,000. When the victim is a first responder — peace officer, firefighter, or EMS — acting in the course of official duties, the charge elevates to a second-degree felony: 2 to 20 years and a fine up to $10,000. An intoxication assault lawyer in Houston examines whether the statutory first-responder requirements are actually satisfied in every enhancement case.
Serious bodily injury under §1.07(a)(46) is injury creating a substantial risk of death, permanent disfigurement, or protracted loss or impairment of any body part or organ. Injuries that fully heal — fractures, lacerations, and sprains — are frequently contested. An intoxication assault lawyer in Houston retains independent medical experts to review injury documentation and provide testimony on whether the legal threshold is satisfied.
Accident reconstruction directly challenges the causation element — §49.07 requires that intoxication caused the accident, not merely that intoxication was present. Herman retains certified reconstructionists who analyze crash physics, vehicle EDR/black box data, road conditions, skid marks, and impact angles. An intoxication assault lawyer Houston clients hire knows that if reconstruction establishes an independent cause of the collision, the causation element of the felony charge cannot be sustained.
Yes — blood draws in accident cases are typically taken at the hospital hours after the crash. Herman challenges the retrograde extrapolation used to estimate BAC at the time of driving, the chain of custody of the blood sample, whether preservatives and anticoagulants were properly used, and lab testing procedures. A successful blood test suppression dramatically weakens the intoxication element of the §49.07 charge.
Yes — §49.07 requires that intoxication be the cause of the accident that caused the injury. If the other driver ran a stop sign, crossed the center line, had defective lights, or was impaired, those facts directly challenge the causation element. Herman investigates all parties' conduct and obtains accident reports, toxicology results for other drivers, and available traffic camera footage to build a comparative causation defense.
A DWI arrest under §49.07 triggers the same ALR license suspension proceeding as any DWI arrest. The deadline to request an ALR hearing is 15 days from the date of arrest. Herman contests the administrative suspension simultaneously with the criminal defense. A §49.07 conviction may also impose a court-ordered suspension in addition to the ALR suspension, making the administrative track equally important to fight. An intoxication assault lawyer Houston drivers call after an arrest handles both the ALR hearing and the criminal defense on parallel tracks from day one.
Civil litigation by the victim frequently runs parallel to §49.07 criminal cases. Statements made in civil depositions can be used in the criminal prosecution. Herman coordinates with civil defense counsel from the outset to ensure civil proceedings do not waive Fifth Amendment protections or create inconsistent accounts that could be used against the criminal defense. Both tracks must be managed together from the beginning.
Make no statements about the accident to law enforcement, insurance adjusters, or on social media. Do not contact the victim or their family. Write down everything you remember about the events leading up to the accident while your memory is fresh. Collect contact information for any witnesses who observed the accident. Call Herman Martinez immediately — early access to the scene, physical evidence, and witness accounts produces the strongest defense.
