A third DWI in Houston is a third-degree felony under Texas Penal Code Section 49.09(b)(2), not a misdemeanor. That means a Harris County grand jury, a district court setting, and a punishment range of two to ten years in the Texas Department of Criminal Justice. Your two prior cases stop being history at that point and become elements the State has to prove.
LaVine Law Firm defends people charged with exactly this offense. As your Houston third time DWI lawyer, we look at how the State intends to prove those priors, how the blood evidence was obtained, and whether the stop that started all of it holds up.

Texas handles a first and second DWI as misdemeanors in county court. The third offense moves the case to a district court with prison exposure attached, and every part of the process changes with it. The charge has to go through a grand jury, the bond conditions get stricter, and the plea options that existed on the earlier cases are gone.
The two prior convictions are not sentencing details. They are elements of felony DWI, which the prosecutor must plead in the indictment and prove to the jury alongside intoxication and operation of a vehicle. The Court of Criminal Appeals said as much in Gibson v. State. If the State cannot prove both priors, the felony charge does not stand.
More convictions qualify than most people expect. Under Texas Penal Code § 49.09, the enhancement can rest on:
A 1998 DWI from another county carries the same weight as one from last spring.
Section 12.34 sets punishment at two to ten years in the Texas Department of Criminal Justice and a fine of up to $10,000. This is prison time rather than county jail. The two-year floor applies to a sentence of confinement, not to every disposition, and community supervision remains on the table.
Section 12.42 changes the arithmetic when there is felony history. One prior final felony conviction moves a third-degree case into the second-degree range of two to twenty years. Two prior final felony convictions, where the second offense occurred after the first conviction became final, push the range to twenty-five to ninety-nine years or life.
Section 49.09(g) sets a limit worth knowing. A single conviction can be used to make the case a felony or to enhance punishment under Chapter 12, but not both.
The courtroom fine is only part of what a conviction costs. Several charges attach separately and are not negotiable in the way a criminal fine sometimes is:
Transportation Code § 521.344 sets suspension at 180 days to two years for a person punished under Section 49.09(b). The floor rises to one year when the new offense falls within five years of the previous one. Section 49.09(h) then keeps the interlock on the vehicle until one year after the suspension ends.
Community supervision is available on a third DWI charge, but probation here does not mean walking out of the courthouse. Texas builds confinement into it by statute.
A judge granting community supervision on a Section 49.09(b) case must order at least ten days in county jail as a condition of that supervision. The statute leaves no discretion. Article 42A.401(b) adds a consequence that rarely gets explained: if supervision is later revoked, those ten days earn no credit against the sentence imposed.
Deferred adjudication is not available on a felony DWI, so resolving the case by plea produces a conviction on your record. The DWI probation conditions a Harris County court will impose belong in the conversation about whether to negotiate or try the case.
The license case runs on its own track and its own clock. It is a civil proceeding at the State Office of Administrative Hearings, decided by a preponderance of the evidence rather than the criminal standard.
Request the hearing within 15 days of the notice or the suspension takes effect on the 40th day after your arrest.
Refusing a specimen carries a 180-day suspension, or two years with a qualifying alcohol or drug contact in the previous ten years under Section 724.035. A failed test carries 90 days, or one year with prior contact. The hearing also puts the arresting officer under oath months before trial, which is why we treat a driver's license suspension after a DWI as part of the defense rather than a side matter.
Because the priors are elements, they are also targets. We order the judgments, court records, and prison packets early, then examine finality, identity, and whether the plea paperwork holds up.
For an out-of-state prior, the question is whether that state's offense contains elements substantially similar to a Texas intoxication offense. Defeating one prior takes the case out of the felony range. That is not a technicality argument. It is the difference between a district court case with prison exposure and a misdemeanor handled in county court.
Section 724.012(b)(3)(B) directs an officer to require a blood specimen from a driver believed to have two or more prior DWI convictions. That subsection is not a substitute for a warrant. Section 724.012(e) bars an officer from requiring a specimen without a warrant or exigent circumstances, and the Court of Criminal Appeals declined to treat the statute as a standalone Fourth Amendment exception in State v. Villarreal.
Warrantless draws still happen. We examine how the DWI blood test results were obtained and whether the affidavit supporting any warrant established probable cause.
A felony DWI reaches a district court by indictment. Bond conditions arrive early, and Article 17.441 generally calls for an interlock after a repeat DWI arrest. Motions to suppress and motions to quash the enhancement paragraphs are litigated before trial, and how those resolve tends to shape what the State is willing to offer.
Harris County prosecutors handle a high volume of these cases and have access to the same criminal history the officer relied on at the scene. Getting ahead of what they intend to prove, rather than waiting for the offer, is where the work starts.
A third DWI carries prison exposure, a felony record, and a license suspension that outlasts the case. It also carries more pressure points than most people are told about, from the finality of a twenty-year-old prior to the warrant behind a blood draw. Those are the places a defense gets built.
