Is a DWI a Felony in TX?

Usually not. A first DWI in Texas is a Class B misdemeanor and a second is a Class A. But there are six ways a DWI becomes a felony, two of them on a first offense with no prior at all, and the grade is only half the question. The other half is whether the State asks for a deadly weapon finding on your car, which can matter more than the grade does.

If you’ve been charged with a felony DWI, call (713) 664-4000. Felony DWI cases are built on old judgments and specific findings, and both can be attacked.

The six routes to a felony DWI

• Two prior intoxication convictions. Penal Code § 49.09(b)(2) makes a third DWI a third-degree felony. This is what most people mean by “felony DWI.”
• One prior intoxication manslaughter. Under § 49.09(b)(1), a single prior under § 49.08 is enough to make the next DWI a third-degree felony.
• A passenger younger than 15. DWI with a child passenger is a state jail felony under § 49.045, first offense or not.
• A school crossing zone. Since September 1, 2025, § 49.04(e) makes a DWI in a school crossing zone, while the reduced speed limit is in effect, a state jail felony. No prior, no crash, no passenger required.
• Someone is seriously hurt. Intoxication assault under § 49.07 is a third-degree felony. It becomes a second-degree felony if the injured person is a firefighter or EMS worker on duty, or if the injury is a brain injury leaving a persistent vegetative state, and a first-degree felony if the injured person is a peace officer or judge on duty (§ 49.09(b-1), (b-4)).
• Someone dies. Intoxication manslaughter under § 49.08 is a second-degree felony, and first degree where the person killed was a peace officer, judge, firefighter or EMS worker on duty (§ 49.09(b-2)).

A second DWI is not on that list. It’s a Class A misdemeanor with a 30-day minimum under § 49.09(a). Neither is a first DWI at 0.15 or higher, which § 49.04(d) makes a Class A. Our page on second DWI penalties covers that one.

What each felony grade carries

• State jail felony: 180 days to two years in a state jail, and up to a $10,000 fine (§ 12.35).
• Third degree: two to ten years in prison, up to $10,000 (§ 12.34).
• Second degree: two to twenty years, up to $10,000 (§ 12.33).
• First degree: five to 99 years or life, up to $10,000 (§ 12.32).

How a felony DWI climbs a grade

A third DWI is a third-degree felony, but § 12.42(a) punishes it as a second degree, two to twenty, if you have a prior final conviction for a felony other than an ordinary state jail felony. That’s how a fourth DWI so often ends up in the second-degree range: a prior felony DWI is usually already on the record.

There’s a limit on that, and it gets missed. Section 49.09(g) says a prior conviction can be used to enhance under § 49.09 or under Chapter 12, but not both. The same prior can’t make the DWI a felony and then bump the felony a grade.

The state jail versions climb too. Under § 12.35(c), a state jail felony is punished as a third-degree felony if a deadly weapon was used or exhibited, which in a DWI case means the vehicle. So a child-passenger DWI or a school-zone DWI can land in the two-to-ten range on a first offense.

The deadly weapon finding is its own fight

A car isn’t a deadly weapon by design, but Texas lets a jury find that it was one by the way it was used. The Court of Criminal Appeals approved that in an intoxication case in Tyra v. State, 897 S.W.2d 796 (Tex. Crim. App. 1995), and prosecutors ask for it routinely in crash cases and sometimes in cases with no crash at all.

The finding changes three things. A judge can’t place you on community supervision under Code of Criminal Procedure Art. 42A.054(b). Parole eligibility moves to half the sentence in actual calendar time, with a two-year floor, under Government Code § 508.145(d). And on a state jail felony, it raises the punishment to third degree under § 12.35(c)(1). The State has to prove the vehicle was used in a way that was actually capable of causing death or serious injury. Hypothetical danger isn’t enough, and that’s where the argument lives.

Your old convictions count, and they have to be proved

There’s no lookback period. Texas repealed its ten-year window for DWI priors in 2005, so a conviction from the 1990s counts the same as one from last year. A probated sentence counts under § 49.09(d). Out-of-state DUI convictions count under § 49.09(c)(1)(F). And a DWI deferred adjudication counts as a conviction for enhancement under § 49.09(g), even though it isn’t one for most other purposes.

What the State has to do is prove each prior, and prove it’s yours. That means a certified judgment and something tying you to it, usually fingerprints. Old misdemeanor judgments are unreliable documents. Fingerprint cards go missing, names get spelled three ways, and court records from the 1990s don’t always survive a clerk’s office move. Knock out one of two priors on a third DWI and the felony becomes a Class A misdemeanor. Our pages on the third DWI and fourth DWI go further into how that works.

Can a felony DWI be expunged or sealed?

Not if you’re convicted. Expunction requires that you were never convicted and never placed on court-ordered community supervision for the offense, and the DWI nondisclosure statute, Government Code § 411.0731, only reaches misdemeanor convictions under § 49.04. A felony DWI conviction is permanent.

A felony DWI charge that ends in a dismissal or an acquittal is different, and whether it can be erased depends on exactly how it ended. Our page on how long a DWI stays on your record walks through the expunction rules.
