Most DWI arrests start as misdemeanors. A few specific circumstances turn them into felonies, and once that happens the case changes shape entirely: prison time replaces county jail, a permanent felony record replaces a wipeable misdemeanor, and the stakes for fighting the charge go up. A Houston felony DWI lawyer has to know exactly which trigger applies to your case, because each one calls for a different defense.
What Turns a DWI Into a Felony
- A third or later DWI conviction. Texas has no lookback period, so a DWI from fifteen years ago in another state still counts.
- A child under 15 in the vehicle. This alone makes a first DWI a state jail felony, even with no prior record.
- Someone was seriously injured. That’s charged as intoxication assault, a separate felony.
- Someone died. That’s intoxication manslaughter, the most serious DWI-related charge in Texas.
The Penalty Range Gets Wide Fast
A felony DWI can mean anywhere from 180 days in a state jail facility to 20 years in prison, depending on which trigger applies and whether you have prior felony convictions. Texas Penal Code § 12.42 can bump a third-degree felony up to second-degree if you have a prior felony on your record, which is how some DWI cases end up carrying decades of exposure.
Why the Defense Strategy Changes
Felony DWI cases draw more prosecutorial attention and less room for a quiet plea deal. Challenging the underlying stop, the field sobriety tests, and the breath or blood evidence still matters, but the margin for error is smaller. Prior convictions used to enhance a charge can sometimes be challenged too, if they weren’t handled correctly the first time.
