Understanding Intoxication Assault in Texas

Intoxication assault occurs when a person operates a motor vehicle while intoxicated and causes serious bodily injury to another person. It is a second-degree felony, but the consequences extend far beyond the criminal penalties.

The Elements:

The State must prove:

You operated a motor vehicle in a public place
You were intoxicated (BAC of 0.08 or higher, or loss of normal use of faculties)
You caused serious bodily injury to another person

What Is Serious Bodily Injury?

Under Texas law, serious bodily injury means injury that:

Creates a substantial risk of death
Causes serious permanent disfigurement
Causes protracted loss or impairment of any bodily member or organ

The Penalty:

Second-Degree Felony: 2 to 20 years in prison
Fine: Up to $10,000
License Suspension: Up to 2 years

What the State Does Not Have to Prove:

Intent to cause harm
Recklessness (intoxication is the substitute for intent)
That the accident was your fault in a civil sense

For residents across Central Texas, an intoxication assault charge carries some of the harshest penalties in Texas law.

What Is the Penalty for Intoxication Assault in Texas?

Intoxication assault is a second-degree felony, punishable by 2 to 20 years in prison and a fine of up to $10,000.

Factors That Affect Sentencing:

Whether there were multiple victims
Whether the victim was a child, peace officer, or emergency responder
Whether you have prior DWI convictions
Your criminal history
Whether you expressed remorse and took responsibility

Enhanced Penalties:

If the victim was a peace officer or emergency responder: First-degree felony (5 to 99 years)
If you have a prior intoxication assault conviction: First-degree felony

Collateral Consequences:

Felony Criminal Record: A permanent felony conviction
Loss of Firearm Rights: A felony conviction results in lifetime prohibition
Loss of Voting Rights: While incarcerated and for a period after
Loss of Professional License: Licensing boards may deny or revoke licenses
Immigration Consequences: Non-citizens face mandatory deportation
Civil Liability: You may face a personal injury lawsuit

For those in the Austin area, an intoxication assault conviction can upend your life.

How to Defend an Intoxication Assault Charge

Defending against an intoxication assault charge requires a strategic approach. The stakes are the highest, and the prosecution will have significant resources.

Defense 1: You Were Not Intoxicated

The State must prove you were intoxicated. Your attorney can challenge:

The field sobriety tests (were they administered properly?)
The breathalyzer (was it properly maintained and calibrated?)
The blood test (chain of custody, storage, draw technique)
Medical conditions that mimic intoxication
Rising blood alcohol (your BAC may have been lower while driving)

Defense 2: The Injury Was Not “Serious”

The State must prove the injury meets the definition of serious bodily injury. Your attorney can challenge:

Whether the injury created a substantial risk of death
Whether the injury caused permanent disfigurement
Whether the injury caused protracted loss or impairment

Defense 3: The Accident Was Not Caused by Intoxication

The State must prove that intoxication caused the serious bodily injury. This is often the weakest link in the State’s case. Your attorney can challenge:

The accident reconstruction
Whether another driver caused the accident
Whether a mechanical failure caused the accident
Whether road conditions contributed
Whether the victim’s actions contributed

Defense 4: Unlawful Stop or Arrest

The Fourth Amendment requires that the officer have reasonable suspicion to stop you and probable cause to arrest you. If the stop or arrest was illegal, the evidence may be suppressed.

Defense 5: Medical Emergency

In some cases, a medical emergency—such as a stroke, seizure, or diabetic episode—may have caused the accident. Your attorney can present medical evidence to support this defense.

Defense 6: Accident Reconstruction

Accident reconstruction is a complex science. Your attorney can hire an independent expert to challenge the State’s reconstruction and present alternative theories.

For those facing these charges across Central Texas, a strong defense can mean the difference between a decade in prison and a reduced sentence.

The Role of Accident Reconstruction

In intoxication assault cases, accident reconstruction is often the centerpiece of the State’s case. Understanding how it works is essential to your defense.

What Accident Reconstruction Involves:

Examining the scene of the accident
Measuring skid marks, vehicle damage, and debris
Analyzing vehicle speeds and trajectories
Determining who had the right of way
Assessing the role of intoxication in the causation

Challenging the Reconstruction:

Your attorney can:

Hire an independent accident reconstruction expert
Challenge the qualifications of the State’s expert
Point out flaws in the methodology
Present alternative theories of causation
Argue that the accident would have occurred regardless of intoxication

For clients in the Austin area, challenging accident reconstruction is often the key to the defense.

Serious Bodily Injury: What It Means

The State must prove that the injury meets the definition of serious bodily injury. This is not always automatic.

What the State Must Prove:

Substantial Risk of Death: Did the injury create a risk of death?
Permanent Disfigurement: Did the injury cause permanent scarring or disfigurement?
Protracted Loss or Impairment: Did the injury cause loss or impairment of a bodily member or organ that lasted for a significant period?

Challenging Serious Bodily Injury:

No Risk of Death: The injury did not create a substantial risk of death
No Permanent Disfigurement: The injury healed without permanent scarring
No Protracted Loss: The impairment was temporary

For those facing charges in Travis County and beyond, challenging the seriousness of the injury can reduce the charge.

Blood Evidence and Chain of Custody

In intoxication assault cases, blood tests are common. The State will use the BAC to prove intoxication. Challenging the blood evidence can be a powerful defense.

How Blood Evidence Can Be Challenged:

Chain of Custody: Was the blood properly handled from draw to analysis?
Improper Draw: Was the blood drawn by a qualified person?
Storage: Was the blood properly stored and refrigerated?
Contamination: Could the sample have been contaminated?
Timing: Was the draw too long after the accident to be relevant?

Independent Testing:

Your attorney can request independent testing of the blood sample. If the independent test shows a different result, the State’s case may be compromised.

For residents of Central Texas, blood evidence can be the strongest evidence against you—or the weakest link in the State’s case.

Causation: The Key to the Defense

The State must prove that intoxication caused the serious bodily injury. This is often the most difficult element for the State to prove.

What Causation Means:

The intoxication must be a substantial factor in causing the injury
The injury would not have occurred but for the intoxication

Challenging Causation:

Other Factors: Was another driver at fault? Was there a mechanical failure? Were road conditions a factor?
Victim’s Actions: Did the victim’s own actions contribute to the accident?
Inevitable Accident: Would the accident have occurred regardless of intoxication?

Expert Testimony:

Your attorney can present expert testimony from accident reconstructionists, engineers, and other professionals to challenge causation.

For clients in Austin and the surrounding areas, causation is often the most powerful defense in an intoxication assault case.

Intoxication Assault vs. Intoxication Manslaughter

If the victim dies, the charge becomes intoxication manslaughter. The difference is the outcome, not the conduct.

Intoxication Assault:

Serious bodily injury
2 to 20 years in prison

Intoxication Manslaughter:

Death occurred
2 to 20 years in prison

For those in Central Texas, the distinction is often a matter of chance—and the defense strategies are similar.
