Texas Felony DWI Lawyer

How Do You Get Out of Jail After a Felony DWI Arrest?

Because a felony DWI is a felony, a magistrate sets bond individually rather than from a misdemeanor schedule, and amounts run higher than a misdemeanor DWI, often well into five figures depending on the level of the charge, any injury, and your record. In intoxication assault and manslaughter cases, where a crash and injuries are involved, bonds and conditions are set with the seriousness of the alleged harm in mind.

Expect strict conditions: a mandatory ignition interlock, no alcohol, and sometimes a portable monitor. A violation can return you to jail while the case is pending, which on a felony can be many months.

The 15-day license deadline starts immediately

If you failed or refused a breath or blood test, the Texas Department of Public Safety moves to suspend your license through Administrative License Revocation, or ALR, a civil process separate from the criminal case. You have 15 days from the date you are served with the notice of suspension to request a hearing. Miss it and the suspension is automatic. Requesting it protects your license and lets your lawyer question the officer under oath early.

What Should You Do Right Now?

A felony DWI goes to a grand jury, and the work done before indictment shapes everything after it. In order:

• Request your ALR hearing within 15 days of notice of suspension. This is the hard deadline. It protects your license and gives your defense an early, sworn look at the arresting officer.
• Do not talk about the case. Not to investigators, not to insurers, not on social media. In a crash case especially, anything you say about speed, drinking, or fault becomes evidence.
• Preserve the vehicle in any crash case. Do not authorize repairs or salvage. The event data recorder holds speed, braking, and steering data from the seconds before impact, often the most reliable evidence in the case.
• Write down what you remember. What you ate and drank and when, the route, road and weather conditions, and what other drivers did.
• Hire counsel immediately. Evidence preservation and early investigation before the grand jury can change the charge that gets returned.

What Makes a DWI a Felony in Texas?

Most DWIs are misdemeanors. Four paths push a DWI up to a felony, each with its own statute and range.

DWI third or more: third-degree felony

Under Penal Code §49.09(b), two or more prior DWI convictions make a new DWI a third-degree felony, 2 to 10 years in prison and a fine up to $10,000.

DWI with a child passenger: state jail felony

Under §49.045, a DWI with a passenger under 15 is a state jail felony, 180 days to 2 years and a fine up to $10,000, even on a first offense with no priors. This is a separate path from the prior-conviction enhancement. See our DWI with Child Passenger page.

Intoxication assault: third-degree felony

Under §49.07, causing serious bodily injury to another by reason of intoxication while operating a vehicle is a third-degree felony, 2 to 10 years, with up to 600 hours of community service. If the victim is an on-duty firefighter or EMS worker, it rises to a second-degree felony, 2 to 20 years; if the victim is an on-duty peace officer or judge, it rises to a first-degree felony, 5 to 99 years or life. See our intoxication assault page.

Intoxication manslaughter: second-degree felony

Under §49.08, causing a death by reason of intoxication while operating a vehicle is a second-degree felony, 2 to 20 years, with up to 800 hours of community service. Texas’s Bentley’s Law (2023) also requires monthly support to the deceased victim’s minor children until each turns 18, an obligation that continues after release. If the victim was an on-duty peace officer, firefighter, or EMS worker, it rises to a first-degree felony, 5 to 99 years or life. See our intoxication manslaughter page.

What Evidence Do Prosecutors Need to Convict You?

A felony DWI rests on the same intoxication proof as any DWI, plus whatever fact makes it a felony, and each piece can fail.

The chemical test. Breath or, more often in felony cases, blood drawn at a hospital and analyzed by gas chromatography. The number is only as reliable as the draw, the storage, the chain of custody, and the lab method behind it.

The prior convictions (on a third or later). Each prior must be proven beyond a reasonable doubt with certified records showing the right person and a valid judgment.

Causation (in assault and manslaughter). The State must prove your intoxication caused the injury or death, not merely that you were intoxicated and present. A road defect, a mechanical failure, or another driver’s fault directly contests that link.

Crash data and reconstruction. The vehicle’s event data recorder and the officer’s reconstruction produce speed, braking, and fault conclusions. These are technical judgments, and they can be wrong.

What Are the Penalties for a Felony DWI in Texas?

The range depends on which felony path applies:

• DWI third or more: third-degree felony, 2 to 10 years, fine up to $10,000.
• DWI with a child passenger: state jail felony, 180 days to 2 years, fine up to $10,000.
• Intoxication assault: third-degree felony, 2 to 10 years, up to 600 hours community service.
• Intoxication manslaughter: second-degree felony, 2 to 20 years, up to 800 hours community service, plus Bentley’s Law support.

Deferred adjudication is not available for any felony DWI. When probation is granted, the statute requires a minimum jail term as a condition, shown below. On-duty first-responder victims raise intoxication assault and manslaughter a full degree.

Jail as a condition of probation, by offense

Can You Fight a Felony DWI?

Yes. Felony DWI cases are won and lost on details that the State’s file treats as settled. Realistic outcomes include dismissal when the stop or warrant fails review, defeating the felony enhancement when a prior cannot be proven, reduction when the causation theory or the science weakens, probation instead of prison, and acquittal at trial.

No lawyer can promise a result, and you should be wary of one who does. What we can tell you is that a blood number, a prior on paper, and a police reconstruction are all things to be tested. Felony cases have been dismissed, reduced, and won because the priors, the science, or the causation did not hold up.

How Is a Felony DWI Different From a Misdemeanor DWI?

A misdemeanor DWI is heard in county court and tops out at 180 days to 1 year in county jail. A felony DWI is heard in district court, carries state prison time, allows no deferred adjudication, and leaves a permanent felony record with the loss of firearm and voting rights during the sentence. The difference is not severity of the same charge; it is a different category of case.

What pushes a DWI across that line is a provable fact: two prior convictions, a child passenger, a serious injury, or a death. Because each of those facts can be contested, the felony line is often exactly where the defense lives. See our second and multiple DWI page for the repeat-offense path.

How We Defend Felony DWI Cases

We challenge the prior convictions

On a third or later DWI, the State has to prove each prior with certified records. We examine those packets for certification defects, identity gaps, and void or incomplete judgments. If a prior cannot be proven, the felony enhancement fails and the case reduces to a misdemeanor.

We attack the blood with science

Managing Partner Deandra Grant holds a Master’s Degree in Pharmaceutical Science, a Graduate Certificate in Forensic Toxicology, and the ACS-CHAL Forensic Lawyer-Scientist designation, and she is a trained SFST instructor. Partner Douglas Huff holds the same ACS-CHAL designation. We pull the full lab package and evaluate the gas chromatography method, calibration, internal standards, and quality control directly, not just whether the result is admissible.

We test the retrograde extrapolation

In crash cases the blood is often drawn hours later, and the State projects your BAC backward to the time of driving using retrograde extrapolation. That projection rests on assumptions about absorption, elimination, and food in the stomach. Pharmaceutical science training lets us challenge whether those inputs were valid and whether the real range of possible BAC values even supports the State’s theory.

We read the crash data

The event data recorder, the vehicle’s own record of speed, braking, and steering before impact, is often more reliable than a reconstruction built afterward. We examine whether the download was done correctly, whether the data was interpreted properly, and whether the collision dynamics actually show that intoxication, rather than road conditions or another driver, caused the harm. Causation is a separate element the State must prove.

We start with the Constitution

Under Texas Code of Criminal Procedure Article 38.23, evidence from a defective warrant or an unlawful stop is suppressible. The validity of the blood warrant and the legality of the stop are the first questions in every felony DWI we build.

Do You Really Need a Lawyer for a Felony DWI?

You will have one either way, because a felony means the court appoints counsel if you cannot afford it. The real question is whether your lawyer has the resources and the forensic background this charge demands. A felony DWI carries prison exposure, no deferred adjudication, and a permanent record, and a quick plea accepts all of it based on evidence no one tested.

Court-appointed lawyers carry heavy caseloads and rarely have funding for independent blood analysis, crash reconstruction, and the time to litigate the priors. A felony DWI is a science case attached to a records case, and the value of private counsel here is the ability to fight both.

How Long Does a Felony DWI Case Take?

Most felony DWI cases take roughly 6 to 24 months from arrest to resolution, and intoxication assault and manslaughter cases can run longer. The timeline moves through arrest and bond, the ALR hearing within weeks, grand jury indictment in the first few months, then discovery, lab-record production, expert analysis, and suppression motions before any trial.

Slow is not bad. Independent lab review, crash reconstruction, and litigating the priors take time, and that work is what produces dismissals and reductions. We keep you informed at every stage.

How Much Does a Felony DWI Defense Cost?

Fees depend on the county, the level of the felony, whether experts are retained, and whether the case resolves before trial. A felony DWI costs more than a misdemeanor because it demands independent forensic work, and that work is precisely what changes outcomes.

We quote a fee after reviewing your case in a free consultation, so you know the investment before you commit. Weigh it against what a felony conviction costs: prison exposure, a permanent record, lost rights, and, in injury cases, civil liability built on the criminal case.

How Felony DWI Cases Move Through North and Central Texas Courts

Felony DWI cases are heard in the district courts. In Dallas County that means the felony courts at the Frank Crowley Courts Building, where blood is typically analyzed at SWIFS or a DPS Lab and lab-record production is an early battle. Tarrant County cases run through the district courts at the Tim Curry Criminal Justice Center in Fort Worth, with blood typically analyzed at the Tarrant County Medical Examiner’s Office or the Fort Worth Crime Lab. Collin, Denton, Rockwall and McLennan County felony cases are heard in their respective district courts.

We appear in these courthouses every week. See our courthouse guides for what to expect at each one.

What Are the Long-Term Effects of a Felony DWI?

Your record. A felony DWI conviction is permanent. It cannot be expunged and does not qualify for nondisclosure, so every background check shows it for life.

Rights. A felony conviction ends your firearm rights and costs you the right to vote during the sentence.

Employment and licensing. A felony record reaches jobs, housing, lending, and professional licensing well beyond the sentence itself.

Immigration. For non-citizens, a felony DWI, and especially an injury case, can carry serious immigration consequences and needs immigration-aware counsel from day one.

Manslaughter cases. Under Bentley’s Law, an intoxication manslaughter conviction adds a child-support obligation that continues after release. The permanence of all of this is the strongest reason to fight the charge now.

Felony DWI FAQs

Is a DWI automatically a felony if someone was hurt?

A DWI that causes serious bodily injury is charged as intoxication assault, a felony, and one that causes a death is intoxication manslaughter. Whether an injury is legally serious is a medical and legal question your defense can contest.

Can a felony DWI be reduced to a misdemeanor?

Sometimes. On a third or later DWI, if one of the two priors the felony depends on can be knocked out, the felony fails and the case proceeds as a misdemeanor. In injury cases, weakening the causation theory can also change the charge.

Is deferred adjudication available on a felony DWI?

No. Deferred adjudication is not available for any felony DWI in Texas, which is one reason early forensic work matters so much. The goal is dismissal, reduction, or acquittal, not a deferred resolution that does not exist here.

What is the event data recorder, and why does it matter?

It is the vehicle’s black box, recording speed, braking, and steering in the seconds before a crash. In assault and manslaughter cases that data is often the most reliable evidence about what actually caused the collision, and it can support or undercut the State’s causation theory.

Can the injured person or the family decide to drop a felony DWI?

No. The State of Texas prosecutes the case, not the injured person or the family. Their wishes can influence the prosecutor but do not control the decision.

Does a felony DWI count if my priors are from another state?

It can. Out-of-state DWI convictions count toward felony enhancement if they are for offenses substantially similar to the Texas one. Each prior has to be examined individually, and some do not hold up.
