When Is DWI a Felony in Texas?
Under Texas Penal Code §49.09, DWI becomes a third-degree felony on a third conviction, carrying 2–10 years in prison and up to $10,000 in fines. A DWI with a child passenger under 15 is a state jail felony on the first offense. Causing serious bodily injury while intoxicated is a third-degree felony (intoxication assault); causing death is a second-degree felony (intoxication manslaughter) with 2–20 years in prison. Texas has no lookback period — a prior conviction from any decade counts. A felony DWI lawyer Houston families call after a third arrest starts by mapping out every prior conviction the state intends to use.
Two prior DWI convictions anywhere in the country — regardless of how long ago — automatically elevate a new charge to a felony.
Even a first-time DWI becomes a state jail felony if a child under 15 was in the vehicle. This charge carries up to 2 years in a state jail facility.
If you cause serious bodily injury to another person while driving intoxicated, you face a third-degree felony charge — 2 to 10 years in prison.
Causing the death of another person while DWI is a second-degree felony — 2 to 20 years in prison, plus up to a $10,000 fine.

A felony DWI lawyer Houston residents consult weighs these collateral consequences alongside the criminal exposure when building a defense strategy.

- DPS surcharges of up to $2,000/year for 3 years
- Required ignition interlock device on all vehicles
How Does a Felony DWI Lawyer Houston Clients Trust Build a Defense?
As a felony DWI lawyer in Houston, Herman defends felony DWI cases by first attacking the prior convictions used to trigger felony elevation. A prior DWI conviction with a defective rights waiver or invalid guilty plea cannot legally elevate a new charge to felony under Texas law. Chemical test reliability and arresting officer testimony are then challenged — beginning at the ALR hearing, before the criminal trial begins. For intoxication assault or manslaughter cases, see the dedicated pages on intoxication assault defense and intoxicated manslaughter defense. Whatever the specific charge, a felony DWI lawyer Houston clients trust begins every case by scrutinizing how the felony enhancement was applied.
Felony elevation requires prior DWI convictions. As a felony DWI lawyer in Houston, Herman reviews each prior conviction for constitutional defects — improper waiver of rights, lack of counsel — that can prevent them from being used. This prior-conviction review is often the single most important task a felony DWI lawyer Houston clients hire undertakes.
Felony cases often involve mandatory blood draws. A felony DWI lawyer Houston clients hire for these cases challenges chain of custody, lab analyst qualifications, testing protocols, and whether the blood draw was properly authorized.
What the officer wrote in their report and what the video actually shows are often different. A felony DWI lawyer in Houston compares every claim in the police report against all available footage.
In intoxication assault and manslaughter cases, a felony DWI lawyer Houston families rely on works with expert reconstructionists to challenge causation — intoxication must have caused the accident, not simply been present.
Felony DWI Questions
In some cases, yes. A felony DWI lawyer in Houston will look at whether the prior convictions used to elevate the charge have constitutional defects, or whether the evidence of intoxication is weak, before negotiating a reduction to a misdemeanor DWI. Challenging prior convictions — including out-of-state ones — is a specialized skill that can change the entire charge level. A felony DWI lawyer Houston defendants trust for a reduction negotiation starts that process by auditing every underlying conviction.
Not necessarily. Many felony DWI cases resolve with probation, intensive supervision, treatment programs, and community service. A skilled felony DWI lawyer Houston clients hire can materially change this outcome — it depends heavily on your attorney's ability to challenge evidence, negotiate with prosecutors, and present mitigating factors to the judge or jury.
A felony DWI conviction cannot be expunged in Texas. Additionally, deferred adjudication is not available for DWI charges in Texas — meaning there is no deferral path to avoid a permanent record. A not-guilty verdict or a full dismissal are the only outcomes that allow expunction of the arrest. For this reason, fighting the charge aggressively rather than accepting a plea is the most consequential decision a felony DWI defendant makes.
Yes. Texas uses out-of-state DWI convictions to elevate charges to felony level. However, out-of-state convictions can sometimes be challenged if the elements of the other state's law don't precisely match Texas DWI elements. Herman reviews every prior conviction — including out-of-state ones — for these challenges. A felony DWI lawyer Houston clients hire who catches a defective out-of-state judgment can keep a case at the misdemeanor level.
Texas has no lookback period limitation for DWI prior convictions. Unlike some states that only count priors within 5 or 10 years, Texas can use a DWI conviction from 20+ years ago to elevate a new charge to a felony. This makes fighting every DWI charge — even old ones — extremely important.
Beyond a third DWI conviction, Texas charges felony DWI when: a child under 15 was in the vehicle (state jail felony), the driver caused serious bodily injury (intoxication assault — 3rd degree felony), or the driver caused death (intoxication manslaughter — 2nd degree felony). Each carries significantly different defenses.
Deferred adjudication is NOT available for DWI charges in Texas — a unique restriction that makes DWI different from most other criminal charges. This means the stakes of every DWI conviction are higher: there is no "deferred" option to avoid a permanent record. Fighting the charge — not just minimizing it — is the most important goal.
A felony DWI conviction in Texas results in loss of the right to vote (while incarcerated or on supervision), loss of the right to possess firearms, ineligibility for jury service, and restrictions on certain professional licenses. Some rights are restored after completing your sentence, but firearms rights require a separate petition process.
Yes. Prior convictions can be challenged if the defendant was not represented by counsel (or did not waive counsel), the guilty plea was not knowing and voluntary, or there were other constitutional defects. A felony DWI lawyer in Houston who successfully challenges a prior means the current charge may not qualify for felony elevation — dramatically changing the case outcome.
Felony DWI cases in Harris County are handled in district courts. Bond is typically set at the initial hearing, and the amount varies based on criminal history, community ties, and the specific facts. A higher bond amount or conditions (like an ignition interlock or GPS monitor) can sometimes be negotiated by an experienced felony DWI lawyer in Houston who knows the judges and prosecutors. Because bond conditions can shape the rest of the case, a felony DWI lawyer Houston clients retain gets involved at the bond hearing itself.
