Charged with a third DWI in Texas?A felony record. State prison. The most aggressive defense Texas DWI cases see.
A third DWI in Texas is a third-degree felony under Tex. Penal Code § 49.09(b)(2) — two to ten years in the Texas Department of Criminal Justice and a fine up to $10,000. Texas has no lookback period for DWI priors. Both prior convictions must be valid and final, and the State must prove every element beyond a reasonable doubt. The stakes are at their highest. So is the available defense leverage.
The misdemeanor ceiling does not apply.
For the first and second DWI offenses, Texas treats the conduct as a misdemeanor — serious, but capped at one year in county jail. The third DWI breaks through that ceiling. Under Tex. Penal Code § 49.09(b)(2), a third DWI in Texas is a third-degree felony when the State proves two prior DWI convictions. The same conduct that was misdemeanor DWI for the first two offenses becomes a felony when it happens a third time.
The third-degree felony classification triggers a different process:
- Indictment by a Harris County grand jury, not just a misdemeanor information
- Felony court — Harris County District Court, not County Criminal Court at Law
- State prison sentence range of 2 to 10 years in TDCJ under Tex. Penal Code § 12.34
- Fine of up to $10,000 in addition to the state traffic fine
- $6,000 state traffic fine at conviction for a 3+ DWI under Tex. Code Crim. Proc. art. 102.020(a)(3)
- Felony record — cannot be expunged or nondisclosed under Tex. Code Crim. Proc. art. 55.01 / Tex. Gov’t Code § 411.0716
- Lifetime firearm disqualification under 18 U.S.C. § 922(g)(1)
What the State must prove for the felony enhancement:
- The driver was intoxicated under Tex. Penal Code § 49.01(2) at the time of the new offense
- The driver operated a motor vehicle in a public place
- The driver has two prior DWI convictions that are final and were not so legally defective they cannot be used
That third element — the validity of both prior convictions — is one of the most powerful defense leverage points in third-DWI litigation.
From misdemeanor to felony.
Class A Misdemeanor
Tex. Penal Code § 49.09(a)
- Jail30 days to 1 year county jail
- FineUp to $4,000
- License Suspension180 days to 2 years
- State Traffic Fine$4,500 at conviction
- RecordMisdemeanor — possibly nondisclosable
Third-Degree Felony
Tex. Penal Code § 49.09(b)(2)
- State Prison2 to 10 years TDCJ
- FineUp to $10,000
- License Suspension180 days to 2 years (felony-level)
- State Traffic Fine$6,000 at conviction
- RecordFelony — cannot be expunged or nondisclosed
Habitual felony offender enhancements under Tex. Penal Code § 12.42 may apply if other prior felony convictions are on the record, extending the punishment range to 25 to 99 years or life.
Texas has no time limit on DWI prior convictions.
Unlike many states, Texas does not have a lookback period for DWI priors. Under Tex. Penal Code § 49.09(e), a prior DWI conviction from any point in the past can be used to enhance the current charge. A DWI from twenty years ago can support a third-DWI felony today.
That rule means the felony enhancement turns entirely on whether the prior convictions are valid and final. Both prior judgments must be on the record. Both must be final — not on appeal, not set aside, not legally defective. If either prior fails, the felony fails.
Common defects in prior DWI convictions:
- Uncounseled pleas — if the defendant was not represented and did not validly waive counsel, the prior may be unconstitutional for enhancement use under Burgett v. Texas
- Insufficient plea admonishments — failure to admonish on the felony enhancement consequences of a future DWI
- Indigency without appointed counsel — if the defendant was indigent and counsel was not appointed
- Plea not knowing or voluntary — under Tex. Code Crim. Proc. art. 26.13
- Prior conviction was actually for a non-DWI offense — obstruction of passageway pleas under § 42.03 do not enhance future DWI
How a third-DWI felony is defended.
A third-DWI defense layers procedural attacks on the current case on top of legal attacks on the prior convictions. Every issue available in a first- or second-DWI defense remains available. Additional issues open up around the validity of the prior convictions used to support the felony.
Are both priors final and valid?
Each prior conviction is examined for finality, voluntariness of plea, counsel waiver, and constitutional defects. A single defective prior collapses the felony.
Was the underlying stop lawful?
Fourth Amendment analysis of reasonable suspicion. A bad stop suppresses everything that follows in the current case.
Were SFSTs properly administered?
HGN, walk-and-turn, and one-leg stand have NHTSA protocols. Deviations affect the reliability of the tests as evidence of intoxication.
Breath and blood challenges
Intoxilyzer 9000 procedural requirements, gas chromatography methodology, chain of custody, warrant validity — all remain available in third-DWI cases.
Mandatory blood draw issues
Under Tex. Transp. Code § 724.012, third-DWI cases qualify for mandatory blood draws. McNeely and Birchfield warrant requirements still apply.
Plea negotiation leverage
Felony exposure increases the stakes of pre-trial motion practice. Procedural wins on motions to suppress create real leverage for reductions or dismissals.
The 15-day ALR clock still applies.
A third-DWI arrest can trigger the Administrative License Revocation process under Tex. Transp. Code Ch. 524. In refusal and breath-failure cases the deadline to request an ALR hearing is 15 days from the Notice of Suspension; in blood-draw cases a 20-day deadline applies from the mailed notice if the result returns at 0.08 or higher. The ALR runs separately from the felony case and on its own clock. Acting quickly on the ALR side preserves driving privileges through the felony proceedings.
Felony DWI requires the most experienced defense available.
Attorney Kenneth V. Mitchell spent 13 years as a Texas police officer before becoming a DWI defense attorney — including service in the Hit and Run and Vehicular Crimes Division of the Houston Police Department. He has personally built DWI cases from the law enforcement side, including the felony enhancement evidence the State must marshal for a third-DWI prosecution.
For a third-DWI felony, that experience matters most. Cross-examining the arresting officer about the current case while simultaneously attacking the validity of two prior convictions requires both knowledge of law enforcement procedure and command of the technical issues that can disqualify priors. Kenneth has both.
Felony stakes. Felony defense.
A third-DWI felony case is the most serious DWI charge in Texas. The procedural and constitutional defenses are also at their most powerful — because the State has to prove more, every link in the State’s chain is another potential break.
