Prior Convictions Change the Charge, But They Don’t Change the Outcome.

A third DWI or another felony-level charge carries more serious consequences than a first or second offense, including enhanced punishment ranges, stricter bond conditions, and greater scrutiny from prosecutors and judges. But the State still bears the same burden of proof it carries in every criminal case. Every element of the offense must be proven beyond a reasonable doubt, and the evidence supporting the charge must hold up to the same scrutiny it would in any other DWI case.

Prior convictions don’t make the stop lawful. They don’t validate a flawed investigation. They don’t make a breath test result reliable if the instrument wasn’t properly maintained or the procedures weren’t followed. And they don’t prevent the defense from identifying and challenging the same legal and factual issues that arise in any DWI case.

At Denuna & Westbrook, PLLC, we represent individuals facing felony DWI charges throughout Houston and the Gulf Coast region. Regardless of your prior record, the State still has to prove its case.

When Does a DWI Become a Felony in Texas?

Under Texas law, two prior DWI convictions can elevate a new charge to a Third-Degree Felony, carrying a prison sentence ranging from two to ten years and a fine of up to $10,000, on top of license suspensions, ignition interlock requirements, probation conditions, and a permanent felony record.

Those consequences are real. But they only come into play if the State can prove its case.

Other offenses that carry felony-level consequences include DWI with a Child Passenger, Intoxication Assault, and Intoxication Manslaughter. This page focuses on felony DWI cases involving prior conviction enhancements.

The State Carries Two Separate Burdens in a Felony DWI Case

A felony DWI prosecution doesn’t just involve one legal question. It involves two, and the State has to satisfy both.

Proving the Current Offense

Under Texas Penal Code Section 49.04, the State must prove that a person operated a motor vehicle in a public place while intoxicated. Texas law defines intoxication three ways: loss of normal mental faculties, loss of normal physical faculties, or a blood alcohol concentration of 0.08 or greater. Prior convictions don’t give the State a pass on its burden of proof. The traffic stop or welfare check, field sobriety testing, breath testing, blood testing, search warrants, and witness credibility can all be examined, challenged, and contested.

Proving the Enhancement Allegations

The existence of a prior conviction isn’t something prosecutors can simply state and assume. They must affirmatively prove the existence of each prior conviction, that it legally qualifies to enhance the current charge, and that the person being charged is the same person who was convicted. Records may be incomplete, improperly certified, or missing required pages, which may prevent a prior conviction from being used for enhancement purposes.

Out-of-state convictions add another layer. Not every conviction from another jurisdiction qualifies as a prior offense under Texas law. Whether a prior conviction meets the legal requirements for enhancement is a question that deserves careful analysis before any decisions about the case are made.

A weakness on either front can significantly change the direction of the case.

Blood Evidence and Search Warrants in Felony DWI Cases

Felony DWI prosecutions often involve blood testing, particularly when a driver declines to provide a breath specimen. In those situations, officers seek a search warrant, and the resulting blood evidence becomes central to what prosecutors present at trial.

That evidence isn’t beyond challenge. Probable cause, the accuracy of warrant affidavits, omissions from supporting documents, execution procedures, and laboratory testing protocols can all become issues worth examining.

Bond Conditions and License Consequences After a Felony DWI Arrest

A felony DWI charge carries immediate practical consequences that start well before any trial.

Courts impose bond conditions that can include ignition interlock devices, alcohol monitoring, travel restrictions, reporting obligations, and abstinence requirements. Violating these conditions creates serious complications that go beyond the bond itself. A dirty drug test, a failed alcohol blow, or a missed check-in can derail an otherwise favorable negotiating position and significantly limit the options available to the defense. Protecting your case starts with protecting the conditions of release.

The arrest also triggers an Administrative License Revocation proceeding that runs on its own timeline, independent of the criminal case. In most cases, the officer issues a Notice of Suspension at the scene, and you have 15 days from that date to request a hearing. The one exception is a consensual blood draw, where the clock doesn't start until DPS receives the lab results and mails a notice to the address on your driver's license. Either way, the deadline is strict, and missing it leads to an automatic suspension.

What Prior Convictions Actually Mean for Your Case

Prior convictions change the classification of the charge. They don’t establish that a person was intoxicated during the current incident, and they don’t relieve the State of its burden to prove the present allegation with admissible evidence.

That distinction is one of the most important things to understand after a felony DWI arrest.

Additional State Fines in Felony DWI Cases

Unlike most criminal charges in Texas, a DWI conviction triggers a mandatory state fine under Texas Transportation Code Section 709.001, separate from whatever fine the court imposes at sentencing.

Because a felony DWI involves a second or subsequent conviction, the baseline mandatory fine is higher than a first-time case. Here are the amounts that may apply:

• Second or subsequent DWI conviction within a 36-month period: $4,500
• Any DWI conviction where a BAC of 0.15 or higher is established at trial: $6,000

These fines stack on top of court costs, probation fees, ignition interlock expenses, and any judge-ordered fine. In a felony DWI case, the total financial exposure from mandatory fines, surcharges, and court-ordered costs can be substantial and should be understood from the beginning of the case.

Open Pleas, PSI Reports, and Punishment Hearings

Not every felony DWI resolves through a negotiated plea with a specific sentence attached. In some cases, a defendant pleads guilty or no contest and submits punishment to the judge, an open plea to the court. These cases proceed to a punishment hearing, and the Pre-Sentence Investigation report becomes one of the most significant documents in the case.

Under Code of Criminal Procedure Article 42A.252, Texas courts are required to order a Pre-Sentence Investigation in felony cases where the judge will be assessing punishment. A community supervision officer conducts the PSI, interviewing the defendant, gathering information about the offense, contacting victims for impact statements, researching criminal history, and evaluating the defendant's family, employment, financial, and educational background. The completed report goes to the judge before the punishment hearing and typically carries significant weight in the sentencing decision.

The PSI is also an opportunity. Defense counsel can supplement the officer's investigation with character letters, employment documentation, evidence of rehabilitation efforts, and other information that presents a more complete picture of who the defendant is beyond the offense itself. A defendant who has already taken steps, attending counseling, maintaining sobriety, or making restitution payments, should have those efforts documented and presented before the hearing.

At the punishment hearing, the State argues for a particular sentence and the defense argues for probation, deferred adjudication, or a reduced sentence. Witnesses may testify. The judge hears from both sides before imposing punishment. The preparation that goes into that hearing shapes everything that follows.

Frequently Asked Questions — Felony DWI in Texas

Does a third DWI automatically mean prison time?

No. A third DWI carries felony punishment exposure, but the outcome depends on the evidence, the jurisdiction, and how the case is resolved.

Can the State use old DWI convictions to enhance a charge?

Yes, but prosecutors must properly establish that those convictions qualify for enhancement and satisfy the applicable evidentiary requirements.

What if one of my prior convictions was in another state?

Out-of-state convictions raise additional questions about whether they qualify for enhancement under Texas law.

Can I get probation on a felony DWI?

Sentencing options depend on the facts, the criminal history, and how the case is resolved.

Will I lose my driver’s license?

Not automatically. License consequences depend on the circumstances of the arrest, whether a specimen was provided or refused, and the outcome of any ALR proceedings.
