DWI Third Offense (Felony DWI) in Texas | Houston Attorney

A third DWI in Texas is a third-degree felony — 2 to 10 years in prison — and the priors that make it a felony are often its biggest weakness. Because Texas has no lookback period, any two prior DWI convictions count, from any state and any era. That means one of the first things we do is test whether those priors are valid and provable. A DWI third also brings some of the harshest pretrial bond conditions in the system.

If you or a loved one has been charged with a felony DWI in Houston, Harris County, or Galveston, Brian Foley and Luis Baez — former Vehicular Crimes prosecutors — can help.

What the Law Covers

A third DWI is charged under Texas Penal Code § 49.04 and enhanced to a third-degree felony under § 49.09 based on two prior DWI convictions. The State must prove the new DWI and both priors. There is no time limit on the priors, and out-of-state convictions can count if they meet Texas's requirements.

Penalty Range

Item	Detail
Offense level	Third-Degree Felony
Prison	2 – 10 years (felony probation often available)

License suspension	Up to 2 years; occupational license may be available
Bond / interlock	Ignition interlock and monitoring commonly required pretrial

How These Cases Are Defended

Attacking the priors. If either prior conviction is invalid or unprovable, the felony enhancement can drop to a misdemeanor. This is the single most valuable line of attack.
Challenging the stop. An unlawful traffic stop leads to suppression.
Field sobriety and testing. We challenge SFST administration and breath and blood results on calibration, maintenance, procedure, and Rule 702 grounds.
Probation and treatment. Where appropriate, we pursue felony probation with treatment instead of prison.
Trial readiness. Prosecutors negotiate differently when they know your lawyer is prepared to try the case.

Collateral Consequences

A felony DWI conviction is permanent, carries prison exposure, loss of firearm and voting rights, professional-license consequences, and long-term monitoring and insurance costs. Because the priors are so often vulnerable, an experienced felony-DWI defense can change everything.

Frequently Asked Questions

Is a third DWI a felony in Texas?

Yes. A third DWI is a third-degree felony under Texas Penal Code § 49.09, punishable by 2 to 10 years in prison and a fine up to $10,000. Any two prior DWI convictions — of any age, from anywhere — can support the felony enhancement, so the priors themselves are a central issue.

Do the prior DWIs have to be recent?

No. Texas has no lookback period for felony DWI enhancement. Two prior DWI convictions count no matter how long ago they occurred, and they can come from other states. Whether each alleged prior is valid and provable is often the most important question in the case.

What bond conditions come with a felony DWI?

Courts routinely impose strict pretrial conditions on a DWI third even before any conviction — including an ignition interlock device, a portable alcohol monitor, regular reporting, and sometimes a deep-lung device or SCRAM ankle monitor. We work to keep those conditions reasonable and workable.

Can a felony DWI be reduced or dismissed?

Yes. We attack the traffic stop, the field sobriety testing, and the breath or blood evidence, and — critically — whether the two alleged priors are valid and usable. If a prior fails, the felony enhancement can collapse to a misdemeanor. Probation and treatment-based outcomes are also possible in appropriate cases.

Will I go to prison for a third DWI?

Not necessarily. While a DWI third carries a 2-to-10-year range, many cases are resolved with felony probation, treatment, and interlock conditions rather than prison — particularly when the defense is strong or a prior is vulnerable. You need an attorney who is prepared to take the case to trial to get the best result.
