Quick answer: Jail beyond the night of arrest is uncommon for a first DWI, even in Williamson County — but this county’s plea policies are stricter than Austin’s, so the path to staying out of jail runs through preparation, not leniency. Probation is the typical outcome for a conviction; a defense that attacks the stop and the testing can do better.
Williamson County earned its tough-on-DWI reputation by design: prosecutors offer less, judges expect compliance, and cases are pushed to resolution rather than left to drift. That does not mean first offenders serve jail time — it means the discounts defendants take for granted in other counties have to be earned here with real defense work: suppression motions, video review, and challenges to the breath or blood evidence.
What should worry you more than jail: the 15-day deadline to request your ALR hearing before your license is automatically suspended, and the permanence of a DWI conviction — Texas never allows one to be expunged. Handle those two correctly and a first arrest in Georgetown or Round Rock is a problem you manage, not a sentence you serve.

Is Williamson County really harsher than Travis County on DWI?
The difference is real but often overstated. Plea offers are leaner and supervision is stricter — but the law, the defenses, and the suppression standards are identical. Cases are won here the same way they are won everywhere: on the stop, the video, and the science.
What penalties does a first DWI carry in Texas?
Class B misdemeanor: 72 hours to 180 days in jail and a fine up to $2,000 plus state fines — Class A if your BAC was 0.15 or higher. Probation is the norm for first convictions, and many cases resolve without a DWI conviction at all.
