Felony DWI Lawyer in Texas

A felony DWI charge in Texas puts your freedom, your license, and your future on the line. Unlike a misdemeanor DWI, a felony conviction can mean years in prison, a permanent felony record, and the loss of rights you may never get back. The law also changed on September 1, 2025, and there are now more ways than ever for a DWI to be charged as a felony in Texas.

Our felony DWI lawyers include former prosecutors and attorneys who are Board Certified in Criminal Law by the Texas Board of Legal Specialization. We defend felony DWI cases across Texas from our offices in Fort Worth, Dallas, Southlake, and Houston.

Most DWI arrests in Texas are misdemeanors. A first DWI is generally a Class B misdemeanor, and even a DWI with a blood alcohol concentration of 0.15 or higher is a Class A misdemeanor, not a felony. Under Chapter 49 of the Texas Penal Code, a DWI becomes a felony in six situations:

• DWI with a child passenger: a passenger younger than 15 makes any DWI a state jail felony, even a first offense.
• DWI in a school crossing zone: as of September 1, 2025, a DWI committed in a school crossing zone while the reduced speed limit applies is a state jail felony, even a first offense.
• Third DWI: two prior intoxication convictions make a new DWI a third degree felony.
• Prior intoxication manslaughter: a single prior intoxication manslaughter conviction makes a new DWI a third degree felony.
• Intoxication assault: causing serious bodily injury to another person is a third degree felony, with enhancements up to a first degree felony.
• Intoxication manslaughter: causing a death is a second degree felony, with enhancements up to a first degree felony.

Each path to a felony has its own elements, its own punishment range, and its own defenses. We cover all of them below.

The 89th Texas Legislature made three significant changes to DWI law that apply to offenses committed on or after September 1, 2025:

• School crossing zone DWI is now a felony. Senate Bill 826 added Penal Code 49.04(e). Driving while intoxicated in a school crossing zone while the reduced speed limit applies is now a state jail felony. No injury, no child passenger, and no prior convictions are required.
• More intoxication manslaughter cases are now first degree felonies. The Legislature expanded Penal Code 49.09 so that intoxication manslaughter is a first degree felony when more than one person is killed in the same criminal transaction, when the person killed is a peace officer, judge, firefighter, or emergency medical services personnel on duty, and in certain cases involving a prior intoxication conviction.
• Any peace officer can now execute a blood warrant. Article 18.067 of the Code of Criminal Procedure was amended so any peace officer may execute a search warrant to collect a blood specimen in intoxication cases, which changes how blood draw evidence is obtained and challenged.

These changes apply only to offenses committed on or after September 1, 2025. Conduct before that date is governed by the prior law. If you were arrested under the new provisions, the State is prosecuting under statutes that courts have barely begun to interpret, which creates opportunities for an experienced defense lawyer.

Under Section 49.045, driving while intoxicated with a passenger younger than 15 years of age is a state jail felony. This is one of two ways a first DWI can be a felony in Texas. To convict, prosecutors must prove:

• The defendant operated a motor vehicle in a public place
• The defendant was intoxicated, as defined by Section 49.01
• A passenger in the vehicle was younger than 15

The punishment range for a state jail felony is 180 days to 2 years in a state jail facility and a fine of up to $10,000. State jail time is served day for day, without parole. A DWI with a child passenger can also be enhanced to a third degree felony under Section 49.09(b) if the driver has prior intoxication convictions.

These cases carry consequences beyond the criminal courtroom. An arrest frequently triggers a Child Protective Services investigation, and a conviction can affect custody and possession orders. Resolving the criminal case the right way matters for the whole family.

Texas’s newest felony DWI took effect September 1, 2025. Under Section 49.04(e), a DWI is a state jail felony if the State proves the person was operating a motor vehicle in a school crossing zone during the time the reduced speed limit applies. “School crossing zone” carries the meaning assigned by Section 541.302 of the Transportation Code.

Two things make this law especially dangerous for drivers:

• It applies to first offenses. A driver with a clean record who passes through a school crossing zone during reduced speed hours can be charged with a felony instead of a Class B misdemeanor.
• The time element is everything. The enhancement applies only while the reduced speed limit is in effect. Whether the zone’s flashing lights were operating, what the posted hours were, and exactly when the driving occurred are all fact issues the defense can attack.

Because this statute is new, prosecutors and courts are still working out how it will be charged and proven. Early representation matters in these cases.

Section 49.09(b) elevates a DWI to a third degree felony based on criminal history. A DWI becomes a felony when the defendant has either:

• Two prior convictions for any combination of intoxication offenses, including DWI, DWI with a child passenger, flying while intoxicated, boating while intoxicated, boating with a child passenger, or operating or assembling an amusement ride while intoxicated, or
• One prior conviction for intoxication manslaughter, or an out-of-state offense with substantially similar elements

Critical points about felony repetition under current law:

• There is no washout period. A DWI from 30 years ago counts the same as one from last year. Prior intoxication convictions are forever available for enhancement.
• Out-of-state convictions count if the offense prohibits operating a vehicle while intoxicated.
• Probated sentences count. Under Section 49.09(d), a conviction on or after September 1, 1994 is final whether the sentence was imposed or probated.
• Deferred adjudication counts. Under Section 49.09(g), deferred adjudication for DWI or boating while intoxicated is treated as a conviction for enhancement purposes.
• Each prior must still be proven. The State must link you to each prior judgment with admissible evidence. Defective judgments, missing records, and identity issues can defeat the enhancement and reduce a felony back to a misdemeanor.

The punishment range for a third degree felony DWI is 2 to 10 years in prison and a fine of up to $10,000. With a prior felony prison sentence, the range can be enhanced to 2 to 20 years under Chapter 12 of the Penal Code, and a defendant with two prior sequential prison trips faces 25 years to life as a habitual offender.

Intoxication assault under Section 49.07 is causing serious bodily injury to another person by accident or mistake while operating a motor vehicle, aircraft, watercraft, or amusement ride while intoxicated. “Serious bodily injury” means injury that creates a substantial risk of death or causes serious permanent disfigurement or protracted loss or impairment of the function of any bodily member or organ.

Intoxication assault is a third degree felony, punishable by 2 to 10 years in prison and a fine of up to $10,000. The offense level increases under current law:

• Second degree felony (2 to 20 years) if the injured person is a firefighter or emergency medical services personnel injured in the discharge of official duties
• Second degree felony (2 to 20 years) if the injury is a traumatic brain injury resulting in a persistent vegetative state
• First degree felony (5 to 99 years or life) if the injured person is a peace officer or judge injured in the discharge of official duties

Causation is the battleground in many intoxication assault cases. The State must prove the intoxication caused the serious bodily injury, not merely that an intoxicated person was involved in a crash. Accident reconstruction, the other driver’s conduct, road conditions, and medical evidence about the injury all matter.

Intoxication manslaughter under Section 49.08 is causing the death of another person by accident or mistake while operating a motor vehicle, aircraft, watercraft, or amusement ride while intoxicated. It does not require any intent to harm. The State must prove:

• The defendant was intoxicated while operating the vehicle in a public place
• The intoxication, and not some other cause, caused the death

Intoxication manslaughter is a second degree felony, punishable by 2 to 20 years in prison and a fine of up to $10,000. Under the 2025 amendments to Section 49.09, it becomes a first degree felony, punishable by 5 to 99 years or life, when:

• The person killed was a peace officer, judge, firefighter, or emergency medical services personnel in the discharge of official duties
• More than one person was killed in the same criminal transaction
• The defendant had a prior intoxication conviction and committed the offense while in violation of Penal Code Chapter 51

When multiple people are killed or injured, the State can bring a separate count for each victim, and the trial court has discretion to stack sentences so they run consecutively. A defendant convicted of intoxication manslaughter must serve the lesser of half the sentence or 30 years before becoming eligible for parole, and good conduct time does not advance that date.

Repeat and Habitual Felony Enhancements

Felony DWI punishment ranges can be enhanced further under Chapter 12 of the Penal Code based on prior felony convictions:

Libertad condicional

• Third DWI and intoxication assault: generally parole eligible when actual time plus good conduct time equals one quarter of the sentence.
• Intoxication manslaughter: must serve the lesser of half the sentence or 30 years in actual time. Good conduct time does not count toward eligibility.
• State jail felonies: state jail time is served day for day with no parole.

A felony DWI conviction follows you long after the sentence ends:

• Driver’s license suspension of 180 days to 2 years, with an additional suspension possible for failing to complete required education programs
• State traffic fines under Transportation Code 709.001 of $3,000, $4,500, or $6,000 on conviction, in addition to the criminal fine
• Ignition interlock requirements as a condition of bond, probation, or an occupational license
• A permanent felony record affecting employment, professional licenses, and housing
• Loss of firearm rights under state and federal law
• Immigration consequences for non-citizens, particularly in injury and death cases

Probation, formally community supervision, is possible in many felony DWI cases, but Texas law builds mandatory jail time into DWI probation. Under Article 42A.401 of the Code of Criminal Procedure, a judge granting probation must require confinement as a condition of probation:

Important limits on probation in felony DWI cases:

• Deferred adjudication is not available for felony DWI, intoxication assault, or intoxication manslaughter.
• A judge cannot grant straight probation for intoxication manslaughter. Only a jury can recommend community supervision in those cases, and only if the defendant has never before been convicted of a felony and the sentence assessed is 10 years or less.
• Felony probation can last up to 10 years, and a violation can result in revocation and a prison sentence within the original range.

Common Conditions of Felony DWI Probation

Beyond the mandatory jail time, felony DWI probation in Texas typically includes a substance abuse evaluation within 30 days and completion of all recommended treatment, a DWI education or repeat offender program, attendance at a victim impact panel, an ignition interlock device on every vehicle you operate, random alcohol and drug testing, community service, monthly reporting and supervision fees, and travel restrictions. In high BAC and repeat cases, judges increasingly order continuous alcohol monitoring (SCRAM) devices. The court keeps authority to modify conditions, add requirements after violations, and revoke probation entirely.

Typical monthly costs add up quickly:

Felony DWI cases are won by attacking the State’s evidence at every layer:

The Stop and Arrest

• Challenging the reasonable suspicion for the stop and probable cause for the arrest
• Suppressing evidence from an unlawful detention or a defective blood warrant
• Reviewing body camera and dash camera footage against the officer’s report

The Science

• Blood draw procedures, chain of custody, and lab accreditation issues
• Breath test maintenance records and operator certification
• Retrograde extrapolation assumptions and rising BAC defenses
• Medical conditions that mimic intoxication or skew test results

The Elements

• Whether the State can prove operation and public place
• Causation in intoxication assault and manslaughter cases, including the other driver’s conduct and road conditions
• The time element in school crossing zone cases
• Defeating prior conviction enhancements through defective judgments, missing records, and identity challenges, which can reduce a felony to a misdemeanor

Varghese Summersett defends felony DWI cases statewide from four offices, and our team includes former state and federal prosecutors who have handled intoxication cases from both sides of the courtroom. Felony DWI charges are not heard in the county courts at law that handle misdemeanor DWIs. They are prosecuted in the felony district courts, where the stakes, the procedures, and the prosecutors are different. Here is where we handle these cases and what to expect in each area.

Fort Worth and Tarrant County

Felony DWI cases in Fort Worth are prosecuted by the Tarrant County Criminal District Attorney and tried in Tarrant County’s felony district courts. Tarrant County treats repeat and injury DWI cases aggressively, and intoxication assault and manslaughter cases here often involve early blood warrants and accident reconstruction. Our Fort Worth DWI lawyers handle felony intoxication cases throughout Tarrant County.

Dallas and Dallas County

In Dallas, felony DWI cases run through the Dallas County District Attorney and the county’s felony criminal district courts. Dallas County’s case volume and its diversion and treatment options can shape how a third DWI or injury case is resolved. Our Dallas criminal defense lawyers defend felony DWI and intoxication cases across Dallas County.

Southlake and Northeast Tarrant County

Southlake sits in Tarrant County, so a felony DWI that starts with an arrest in Southlake, Grapevine, Colleyville, or Keller is prosecuted in the Tarrant County felony courts in Fort Worth. Early representation in Northeast Tarrant cases matters because charging decisions and ALR deadlines move quickly. Our Southlake criminal defense lawyers represent clients throughout Northeast Tarrant County.

Houston, Harris County, and Fort Bend County

In the Houston area, felony DWI cases are prosecuted in the Harris County district courts and, for arrests in Sugar Land, Richmond, Rosenberg, and the rest of Fort Bend County, in the Fort Bend County district courts. The two counties charge and resolve intoxication cases differently, and knowing each is part of building the defense. Our Houston DWI lawyers handle felony DWI cases across Harris County and Fort Bend County.

Is a DWI a felony in Texas?

Most DWIs in Texas are misdemeanors. A DWI becomes a felony if there is a child passenger younger than 15, if it happens in a school crossing zone during reduced speed hours, if the driver has two prior intoxication convictions or a prior intoxication manslaughter conviction, or if someone is seriously injured or killed.

Is a first DWI a felony in Texas?

Usually no. A first DWI is a Class B misdemeanor, or a Class A misdemeanor with a BAC of 0.15 or more. But a first DWI is a state jail felony if a child younger than 15 was in the vehicle or, under the law effective September 1, 2025, if the offense occurred in a school crossing zone while the reduced speed limit applied.

How many DWIs is a felony in Texas?

A third DWI is a felony. Two prior convictions for DWI or other intoxication offenses make a new DWI a third degree felony punishable by 2 to 10 years in prison. There is no time limit on how old the priors can be.

Is a DWI with a high BAC a felony?

No. A DWI with a BAC of 0.15 or more is a Class A misdemeanor, not a felony. The Legislature considered making it a felony in 2025, but that bill did not pass. A high BAC does increase fines, interlock requirements, and how prosecutors treat the case.

Can a felony DWI be reduced to a misdemeanor?

Sometimes. If the State cannot properly prove a prior conviction, a felony repetition case can fall back to a misdemeanor. Felony charges can also be reduced through negotiation, suppression of evidence, or proof problems on an element like the school zone time window or causation.

Can you get probation for a felony DWI in Texas?

Often yes, but Texas law requires jail time as a condition of DWI probation: at least 10 days for a felony DWI, 30 days for intoxication assault, and 120 days for intoxication manslaughter. A judge cannot grant straight probation for intoxication manslaughter; only a jury can recommend it.

How long does a felony DWI stay on your record?

Forever. A felony DWI conviction cannot be expunged or sealed in Texas. This is one of the most important reasons to fight the charge before conviction rather than hope for relief afterward.

The difference between a felony conviction, a reduced charge, and a dismissal usually comes down to what your lawyer does in the first weeks after arrest. Evidence disappears, ALR deadlines pass, and charging decisions get made early.
