What Are the Penalties for Intoxication Manslaughter in Dallas?

Intoxication manslaughter in Dallas is often a second-degree felony punishable by 2 to 20 years in the Texas Department of Criminal Justice and a fine of up to $10,000. Some cases can be punished as first-degree felonies, and a conviction can also bring driver-license consequences, restitution obligations, and limits on community supervision or parole depending on the facts.

 

What is intoxication manslaughter in Dallas?

Texas Penal Code § 49.08 applies when a person is intoxicated while operating a motor vehicle in a public place and, by reason of that intoxication, causes another person’s death by accident or mistake. Prosecutors do not have to prove an intent to kill, but they do have to prove intoxication, operation, and the required causal connection to the death.

Texas defines intoxication by a blood-alcohol concentration of 0.08 or more or by loss of normal mental or physical faculties because of alcohol, drugs, or a combination of substances. Our guide to a first DWI in Texas explains the basic DWI definition, while the fatality element makes an intoxication manslaughter case substantially more serious.

What is the standard prison sentence for intoxication manslaughter?

The baseline offense is a second-degree felony. Under Texas Penal Code § 12.33, the punishment range is 2 to 20 years in prison and a possible fine of up to $10,000.

The criminal sentence is not the only consequence. Texas law generally requires a person charged with intoxication manslaughter to use an ignition-interlock device as a condition of release on bond, unless the magistrate finds a statutory exception applies. A conviction can also affect driving privileges, and the exact license consequence depends on the person’s record and current law.

When can intoxication manslaughter become a first-degree felony?

Texas law increases punishment in specific circumstances. A first-degree felony generally carries 5 to 99 years or life in prison and a fine of up to $10,000.

What if more than one person dies in the same crash?

For offenses committed on or after September 1, 2025, Senate Bill 745 allows first-degree felony treatment when intoxication manslaughter causes the death of more than one person during the same criminal transaction. The offense date therefore matters in a multiple-fatality case.

What if the victim was a protected public servant?

Texas Penal Code § 49.09 provides first-degree felony treatment when intoxication manslaughter causes the death of a protected public servant described in the statute. That includes a peace officer or judge, as well as a firefighter or emergency medical services worker acting in the actual discharge of official duties.

What changed under Grayson’s Law?

Grayson’s Law, House Bill 2017, took effect September 1, 2025. It creates first-degree felony treatment and stricter community-supervision and parole rules only in a narrow category of intoxication manslaughter cases; the defendant must have a prior qualifying intoxication-related conviction and, at the time of the new offense, be in violation of Texas Penal Code Chapter 51. It is not a blanket 10-year minimum for every intoxication manslaughter case.

Can you get deferred adjudication for intoxication manslaughter?

No. Texas law bars deferred adjudication for intoxication manslaughter. Community supervision is a separate question and can depend on how punishment is assessed, criminal history, and whether the judgment includes a deadly-weapon finding or another statutory restriction.

What does a deadly-weapon finding change?

A motor vehicle can support a deadly-weapon finding when the evidence meets the legal standard. That finding can bar judge-ordered community supervision in circumstances covered by Texas law and can materially affect parole eligibility, so it should be treated as a separate sentencing issue rather than routine wording in the judgment.

Can a conviction require payments for the victim’s children?

Yes. Texas Code of Criminal Procedure Article 42.0375 requires restitution for a child whose parent or guardian was killed in an intoxication manslaughter offense. The court sets a monthly amount after considering the child’s needs, the surviving household’s resources, and the defendant’s financial circumstances. Payments generally continue until the child turns 18 or graduates from high school, whichever is later, subject to the statute.

What evidence matters in a Dallas intoxication manslaughter case?

The central issues are usually intoxication, operation, and causation. A fatal crash does not by itself prove that intoxication caused the death.

The evidence may include body-camera and dash-camera video, crash-scene photographs, surveillance footage, event-data-recorder information, witness statements, blood testing, hospital records, toxicology, and accident reconstruction. When blood evidence is involved, the timing of the draw, collection procedures, warrants, chain of custody, and laboratory methods can all matter.

How is intoxication manslaughter different from intoxication assault?

The difference is the result. Intoxication assault applies when intoxicated operation causes serious bodily injury; intoxication manslaughter applies when it causes a death. Intoxication assault is generally a third-degree felony, while intoxication manslaughter begins as a second-degree felony.

Why does trial preparation matter in an intoxication manslaughter case?

The possible punishment is severe, but the State still has to prove every element and any requested enhancement. A defense should examine not only the toxicology result but also whether the testing is reliable, whether the crash evidence proves causation, and whether the facts support a deadly-weapon finding or higher punishment level.
