Intoxication Assault in Texas: Charges, Penalties, and Your Defense
You never meant for anyone to get hurt. Under Texas law, that fact alone will not save you. When prosecutors believe you were intoxicated behind the wheel and someone else was seriously injured in the crash, what might have been a standard Texas DWI becomes intoxication assault — a third-degree felony that can send you to prison for up to ten years. The charge carries the weight and stigma of a violent felony even though no one intended to hurt anyone. In the space of one night, an accident became a violent felony.
If you or someone you love is facing intoxication assault charges in Montgomery County or Walker County, you already feel how much is at stake: your freedom, your license, your job, your family's future. Hold on to this anyway: an arrest is not a conviction. The state must prove every element of this charge beyond a reasonable doubt, and every element can be challenged. At Griffin & Cain, Attorneys at Law, our criminal defense team in Conroe fights these cases aggressively. This page explains what the charge means, what you face, and where these cases are won. When you are ready to talk through your own situation, a complimentary consultation with our Conroe team is a phone call away.
What the State Must Prove, and Why "It Was an Accident" Is Not a Defense
Intoxication assault is defined by Section 49.07 of the Texas Penal Code. Strip away the legal language, and the prosecution must prove four things beyond a reasonable doubt:
- You were intoxicated. Texas law defines intoxication as a blood alcohol concentration of 0.08 or higher, or the loss of the normal use of your mental or physical faculties because of alcohol, drugs, or a combination of substances.
- You were operating a motor vehicle in a public place. The same law covers watercraft, aircraft, and amusement rides.
- Another person suffered serious bodily injury. Not just any injury — the law sets a specific threshold that matters enormously to your defense.
- Your intoxication caused that injury. The state must tie the injury to your intoxication itself, not merely to the fact that a crash occurred.
Notice what is missing from that list: intent. The statute says the injury can be caused "by accident or mistake," which means the state never has to prove you meant to harm anyone. It only has to show that you were intoxicated, that you were driving, and that your intoxication caused the crash that seriously injured someone else. That is the shock at the center of this charge.
But the list cuts both ways: each element is a separate hurdle for the state, and in our experience, each one can be attacked — the stop, the blood evidence, the crash analysis, the medical records.
What Counts as a "Serious Bodily Injury"?
The felony often rises or falls on how badly the other person was hurt. The Penal Code defines serious bodily injury as bodily injury that creates a substantial risk of death, causes death, causes serious permanent disfigurement, or results in protracted loss or impairment of the function of any bodily member or organ.
In practice, prosecutors point to injuries such as broken bones requiring surgical repair, traumatic brain injuries, spinal cord injuries, loss of consciousness, internal organ damage, injuries requiring extended hospitalization, and injuries that leave permanent scarring or disability. The injury does not need to be life-threatening to qualify, but it must go beyond minor cuts, bruises, or soreness.
Here is why that matters: the line between "bodily injury" and "serious bodily injury" is one of the most contested issues at trial, and which side of that line your case falls on can decide whether the charge remains intoxication assault or is reduced to a lesser offense. The mistake we see most often is assuming the state's label is final. It is an allegation, and allegations can be challenged.
The Penalties You Are Facing
Intoxication assault is a third-degree felony, punishable by two to ten years in the Texas Department of Criminal Justice and a fine of up to $10,000. A conviction also brings a driver's license suspension of 90 days to two years, and the court can add conditions: probation, an ignition interlock device, drug and alcohol evaluation and treatment, community service, and restitution to the victim. This is a different universe from standard DWI penalties and fines.
The 2025 legislative session raised the stakes further by expanding the circumstances under which an intoxication assault charge can be elevated. If the person injured was a peace officer, judge, firefighter, or emergency medical services personnel acting in the line of duty, the charge may be enhanced. When more than one person suffers serious bodily injury in the same crash, the state can file a separate charge for each victim, and the court may order those sentences to run consecutively — stacked one after another — rather than concurrently. And if a victim dies, the charge becomes intoxication manslaughter, a second-degree felony carrying two to twenty years in prison.
Restitution deserves its own warning. The court can order you to pay the victim directly for medical expenses, lost wages, property damage, and other documented losses. And the criminal case does not end your exposure: if the victim files a civil lawsuit, a criminal conviction can be used as evidence of liability in that proceeding as well.
One door is closed from the start. Deferred adjudication is not available for intoxication assault — Texas law specifically excludes this offense. If you have been reading about DWI deferred adjudication, it will not apply here: plead guilty or be convicted, and a felony conviction goes on your record permanently.
With no deferred adjudication safety valve, everything rides on the defense. If you have been arrested for intoxication assault in Montgomery County or Walker County, contact our Conroe office now — the sooner we start examining the blood evidence and the crash findings, the more of the state's case we can put to the test.
How Police Build an Intoxication Assault Case
These cases begin in chaos. Officers respond to a serious crash, secure the scene, and assess the injuries — and while that happens, an impaired driving investigation is already underway. Officers look for the odor of alcohol, open containers, slurred speech, and erratic behavior. From the first minutes at the scene, you are under investigation.
Then comes the blood. Because these cases involve serious injury, Texas's mandatory blood draw law authorizes officers to take your blood without a warrant when they have reasonable grounds to believe intoxication contributed to the crash. That draw often happens at the hospital, while you are being treated for your own injuries, and the sample is analyzed for both alcohol and drug content. How that sample was collected, stored, and tested can make or break the state's case — our page on breath and blood tests in Texas DWI cases explains how this evidence works and where it breaks down.
The state will also try to reconstruct the crash itself. Accident reconstruction experts analyze skid marks, vehicle damage patterns, the point of impact, and speed estimates to argue that your vehicle caused the collision and that the collision caused the injuries. Every step of that analysis involves human judgment — and judgment calls can be tested. Our overview of the DWI legal process in Texas maps how a felony case moves from arrest to resolution.

A Few Words From Satisfied Clients
Our last review post was a year ago; Brian has continued to provide excellent work and advice on legal matters.
What to Expect in Montgomery County
In Montgomery County, intoxication assault cases are prosecuted in the District Courts and handled by experienced felony prosecutors in the Montgomery County District Attorney's Office. The state pours significant attention and resources into these cases. Your defense must be equally thorough and equally prepared.
At Griffin & Cain, our Conroe attorneys have experience defending serious felony DWI charges in Montgomery County courts. We investigate every aspect of the case, retain expert witnesses when needed, and pursue every available defense to protect our clients' rights. We represent people throughout Conroe, The Woodlands, Huntsville, and the surrounding Montgomery County and Walker County communities.
How We Fight an Intoxication Assault Charge
Severe penalties do not make a charge unbeatable. The prosecution must prove every element beyond a reasonable doubt, and each element gives a prepared defense somewhere to strike.
Challenging the Intoxication Evidence
The state must prove you were intoxicated at the time you were driving — not an hour or more later at the hospital. If the blood sample was improperly collected, stored, or analyzed, the results can be challenged. Rising blood alcohol, medical conditions, and the delay between the crash and the blood draw can all mean the number on the lab report does not reflect your actual condition behind the wheel.
Challenging Causation: The Real Battleground
Causation is the most frequently litigated issue in these cases, because the state must prove your intoxication caused the injury — not simply that you were intoxicated and a crash happened. If the other driver was at fault, if a third party's actions contributed, if road conditions or a mechanical failure played a role, or if the crash would have occurred regardless of intoxication, the causation element gives way. The first thing we do when we take a case like this is scrutinize the crash itself, because in our experience, fault is often far less settled than the police report makes it look.
Challenging the Severity of the Injury
The felony requires serious bodily injury as the law defines it. Medical records, expert testimony from treating physicians, and independent medical evaluations can all be used to dispute whether the injuries truly meet that definition. When they do not, the felony charge may be reduced.
Holding the Investigation to the Constitution
If officers violated your constitutional rights — an unlawful search, blood draw procedures that were not followed, a warrant obtained without sufficient probable cause — the evidence they gathered can be suppressed. Suppression motions in felony cases demand careful legal analysis and aggressive advocacy, and a successful one can take the heart out of the state's case. Our guide to your rights during a DWI stop explains what officers can and cannot lawfully do.
The Other Clock: Your Driver's License
While the felony case develops, a faster deadline is already running. An intoxication assault arrest triggers a separate Administrative License Revocation (ALR) proceeding through the Texas Department of Public Safety, and Texas law gives you just 15 days from the date of your arrest to request a hearing to challenge the administrative suspension of your driver's license. That deadline applies no matter how serious the criminal charge is. Our ALR license suspension page explains how the hearing process works.
If your 15 days are already running, contact our Conroe office today — the hearing request takes minutes to file, and it preserves your license while we fight the felony.
Frequently Asked Questions About Intoxication Assault
What is the difference between a DWI and intoxication assault?
A standard DWI means operating a vehicle while intoxicated, typically without an accident or injury, and a first or second offense is usually a misdemeanor. Intoxication assault adds one devastating element: your intoxicated driving caused serious bodily injury to another person. That added element makes it a third-degree felony every time.
Can I get probation for intoxication assault?
Probation is possible in some cases, but no one should count on it. Courts have discretion to order community supervision, the conditions are strict, and jail time as a condition of probation is common for felony-level offenses. Whether probation is realistic depends on the facts, your criminal history, and the strength of your defense.
What if the other driver caused the accident?
That can be a powerful defense, because the state must prove that your intoxication caused the injury. If another driver's negligence or recklessness was the actual cause of the crash, the felony charge may not hold. Fault is often less settled than the police report suggests, which is why the crash itself deserves close scrutiny.
Will I face a civil lawsuit in addition to the criminal charges?
In many cases, yes. The injured person can file a separate civil lawsuit seeking damages for medical expenses, lost wages, pain and suffering, and other losses. A criminal conviction can be used as evidence in that civil case, which is one more reason to fight the criminal charge aggressively from the start.
Can intoxication assault charges be reduced?
Depending on the evidence, it may be possible to negotiate a reduction to a lesser charge such as a standard DWI or reckless driving. Whether that is realistic turns on the strength of the state's evidence, the severity of the injuries, and the specific facts of your case. An experienced defense attorney can evaluate whether a reduction is a genuine option in yours.
What is intoxication manslaughter, and how is it different?
Intoxication manslaughter applies when intoxicated driving causes another person's death rather than a serious injury. It is a second-degree felony carrying two to twenty years in prison. The dividing line is the outcome: serious bodily injury means intoxication assault, a third-degree felony, while a death means intoxication manslaughter, a second-degree felony.
Protect Your Future After a Serious DWI Charge
An intoxication assault conviction can change your life permanently. Prison time, a felony record, restitution, and the loss of your driving privileges are all on the table — but none of it is inevitable, because an arrest is not a conviction. At Griffin & Cain, Attorneys at Law, we take these cases seriously because the consequences are serious. We take the state's case apart detail by detail — the stop, the blood draw, the crash reconstruction, the medical records — challenge every weakness in the evidence, and fight for the best possible outcome.
If you are facing intoxication assault charges in Conroe, The Woodlands, Huntsville, or anywhere in Montgomery County or Walker County, contact our Conroe office today to schedule a complimentary consultation. A felony this serious demands experienced, aggressive representation from the very beginning — before the state's version of that night becomes the only version anyone hears.
