Felony DWI in Texas — What a Third Offense Actually Means in Bexar County

A third DWI conviction in Texas is not a more serious version of a misdemeanor — it is a fundamentally different category of offense with a fundamentally different set of consequences. Under Texas Penal Code Section 49.09(b)(2), a person convicted of DWI who has two prior DWI convictions is guilty of a third-degree felony. That means the case is heard in one of Bexar County’s criminal district courts rather than a county court at law, the potential sentence is two to ten years in the Texas Department of Criminal Justice rather than county jail, and the permanent record that follows a conviction is a felony record — not a misdemeanor.

There is no deferred adjudication available for any DWI charge in Texas, including a felony DWI. A plea of guilty or no contest is a conviction. Understanding the full scope of what a felony DWI conviction means — and what the defense options are in Bexar County before any plea is entered — is the starting point for anyone facing this charge.

How Texas Law Elevates a DWI to a Felony

A DWI charge in Texas becomes a felony under Texas Penal Code Section 49.09 in four distinct situations, not just the third-offense scenario most people know about.

• The most common pathway is two prior DWI convictions, which elevates the new charge to a third-degree felony regardless of when the prior convictions occurred or whether they happened in Texas or another state. Out-of-state DWI convictions count toward the enhancement under Texas law if the elements of the out-of-state offense are substantially similar to Texas’s DWI statute.
• A DWI also becomes a state jail felony — a separate and distinct felony category — under Section 49.045 when a child under the age of 15 was a passenger in the vehicle at the time of the offense. This enhancement applies even to a first-time DWI with no prior record.
• Intoxication assault under Section 49.07 occurs when a person, by reason of intoxication, causes serious bodily injury to another person while operating a motor vehicle. This is a third-degree felony carrying two to ten years in TDCJ.
• Intoxication manslaughter under Section 49.08 occurs when a person, by reason of intoxication, causes the death of another person while operating a motor vehicle. This is a second-degree felony carrying two to twenty years in TDCJ and a fine of up to $10,000.

The Penalties for a Felony DWI Conviction in Texas

A third-degree felony DWI in Texas carries a sentence of two to ten years in the Texas Department of Criminal Justice and a fine of up to $10,000. Unlike a first or second-offense DWI — where probation without any jail time is a possible outcome — a felony DWI conviction comes with mandatory consequences that are difficult to mitigate without an effective defense.

The collateral consequences of a felony DWI conviction are significant and permanent. A felony conviction results in the loss of the right to possess a firearm under both Texas and federal law. It affects professional licensing — nurses, teachers, attorneys, contractors, and other licensed professionals face potential license suspension or revocation following a felony conviction. It appears on every background check for employment, housing, and professional applications for the rest of the defendant’s life. And it affects immigration status for non-citizens, potentially resulting in deportation or inadmissibility.

Perhaps most significantly for someone who has prior DWI convictions and is now facing a felony charge, the habitual offender enhancement under Texas Penal Code Section 12.42 applies if the defendant has two prior felony convictions from any category. If a third-offense DWI felony is the second felony conviction, a fourth DWI — or any subsequent felony — would trigger the habitual offender enhancement, which carries a mandatory minimum of 25 years.

How Prior Convictions Are Used — and Challenged — in Felony DWI Cases

The prior convictions that elevate a DWI from a misdemeanor to a felony must be proven by the state beyond a reasonable doubt. This is not automatic — the state must introduce evidence that the prior convictions occurred, that the defendant is the same person who was convicted, and that the prior offenses meet the legal elements required under Texas law for enhancement purposes.

Prior convictions can be challenged on several grounds. If a prior conviction was obtained without a valid waiver of the defendant’s right to counsel, it may be constitutionally defective and therefore unusable for enhancement. If the records introduced by the state are incomplete or fail to establish that the defendant in the prior case is the same individual facing the current charge, the enhancement fails. These challenges require careful review of the records from each prior conviction — including the charging instrument, the judgment, and the documentation of how the prior plea was taken.

Defense counsel should obtain and review the complete record of every prior conviction the state intends to use for enhancement before any plea discussions begin.

How Felony DWI Cases Are Defended in Bexar County

The defense of a felony DWI in Bexar County proceeds through the same analytical framework as any DWI case — the legality of the traffic stop, the administration of field sobriety tests, the reliability of breath or blood test results — but with the additional layer of the prior conviction challenge described above.

The 15-day Administrative License Revocation deadline applies to felony DWI arrests exactly as it does to misdemeanor arrests. An attorney must request the ALR hearing within 15 days of the arrest date or the license suspension becomes automatic. At Barton & Associates, we request ALR hearings for every DWI client, including felony DWI, at no additional charge.

In cases where the prior convictions are valid and the current offense evidence is strong, the defense focus shifts to mitigation — building the most complete picture of the defendant’s circumstances, treatment history, employment, and family situation to argue for the minimum sentence or, where available, felony probation rather than prison time. Texas courts can place a defendant convicted of a third-degree felony DWI on community supervision — probation — in appropriate cases, but the conditions of that probation are significantly more demanding than those imposed on misdemeanor DWI defendants, and any violation carries the risk of revocation and prison time.

The decision about how to proceed in a felony DWI case — whether to challenge the prior convictions, suppress evidence, take the case to trial, or negotiate — requires a complete factual and legal analysis that cannot be done without reviewing every document in the case from the current arrest and every prior conviction the state intends to use.
