What Is Felony DWI in Texas?: When a DWI Becomes a Third-Degree Felony

Gavel and law books representing felony DWI prosecution
Quick Answer

A third or subsequent DWI in Texas is a third-degree felony under Penal Code §49.09(b), punishable by 2 to 10 years in TDCJ and up to $10,000 in fines. Felony DWI also includes intoxication assault (§ 49.07 — third-degree), intoxication manslaughter (§ 49.08 — second-degree), and DWI with a child passenger (§ 49.045 — state jail felony).

A third DWI conviction in Texas is no longer a misdemeanor — it's a third-degree felony carrying 2 to 10 years in the Texas Department of Criminal Justice. If you're facing a felony DWI charge in Collin County or DFW, here is what you need to know.

When a DWI Becomes a Felony

Texas has five ways a DWI becomes a felony under Chapter 49 of the Penal Code:

  1. Third or subsequent DWI (§ 49.09(b)): Third-degree felony — 2 to 10 years TDCJ
  2. DWI with child passenger under 15 (§ 49.045): State jail felony — 180 days to 2 years
  3. Intoxication assault (§ 49.07): Third-degree felony — 2 to 10 years
  4. Intoxication manslaughter (§ 49.08): Second-degree felony — 2 to 20 years
  5. Aggravated intoxication manslaughter (peace officer/firefighter/EMS, § 49.09(b-2)): First-degree felony — 5 to 99 years

The "Two Prior Convictions" Requirement

Under § 49.09(b), the third DWI becomes a felony if the defendant has been “previously convicted” of two DWI offenses. Key points:

The State must prove prior convictions with certified judgments — proof is not presumed.

Defending Felony DWI Charges

Challenge the Priors

The State must prove each prior conviction. Defense often involves:

Suppression Motions

Every felony DWI case requires aggressive motion practice — challenging the stop, field sobriety tests, breath/blood evidence, and any statements.

Constructive Possession of Vehicle

If the defendant was not actually driving (passenger, bystander to an accident), the State faces challenges proving operation of a motor vehicle.

Collin County Felony DWI Practice

Felony DWI cases in Collin County are indicted by the grand jury and assigned to one of the felony district courts (366th, 380th, 416th, 417th, 429th, 469th, or 470th). Bonds are typically higher than misdemeanor DWI — $5,000 to $20,000 depending on priors and aggravating factors.

Pre-trial diversion is generally unavailable for felony DWI. Deferred adjudication was historically unavailable for third-offense DWI, though recent legislative changes have expanded eligibility in limited circumstances.

Intoxication Assault and Manslaughter

When DWI causes injury or death, the charges escalate dramatically:

These cases require specialized defense involving accident reconstruction experts, medical examiner challenges, and forensic toxicology review.

Frequently Asked Questions

When does a DWI become a felony in Texas?

Third or subsequent DWI (§ 49.09(b)), DWI with child passenger under 15 (§ 49.045), intoxication assault (§ 49.07), and intoxication manslaughter (§ 49.08) are all felonies.

Can a felony DWI be reduced to a misdemeanor?

In limited cases, yes — through successful motion practice, challenges to the priors, or negotiated pleas to lesser-included offenses. However, most felony DWI cases stay at the felony level.

What's the minimum sentence for felony DWI?

2 years TDCJ for third-degree felony DWI, though probation is available in most cases. Intoxication manslaughter also starts at 2 years.

Do out-of-state DWI convictions count as priors?

Yes, if the conduct would be a DWI under Texas law. Out-of-state DUI, OUI, and similar offenses typically qualify.

Can I own a gun after felony DWI?

No, under federal law (18 U.S.C. § 922(g)(1)) and Texas Penal Code §46.04. The prohibition is lifetime for federal purposes and 5 years for certain Texas offenses.
