Updated August 2026 · Texas Penal Code § 49.09 · Transportation Code § 709.001

A second DWI in Texas isn't "another misdemeanor" — it's the charge where the system stops offering second chances. Mandatory jail minimums, required ignition interlock, a multi-year license suspension, and a harsh truth: Texas DWI priors never wash out. A conviction from 20 years ago counts the same as one from last year.

What a second DWI carries

PenaltySecond DWI (Class A misdemeanor)
Jail30 days to 1 year (30-day minimum even with probation)
Court fineUp to $4,000
State fine (§ 709.001)$4,500 on top of the court fine
License suspension180 days to 2 years
Ignition interlockMandatory as a condition of bond and any occupational license

No washout period — and out-of-state priors count

Unlike some states where old DWIs age off after 7 or 10 years, Texas counts every prior intoxication conviction for life — including convictions from other states and even boating while intoxicated. Defense attorneys scrutinize the prior itself: defective paperwork, uncounseled pleas, or priors that can't be properly proved can keep a new charge at first-offense level. That fight happens at the enhancement stage and is one of the highest-value motions in repeat-offense defense.

What changes strategically on a second offense

  • Probation still exists, but with teeth. Courts can probate a second DWI, but the 30-day minimum jail term, interlock, and intensive conditions are typically non-negotiable.
  • DWI court becomes relevant. Denton County and other DFW jurisdictions run specialty DWI courts for repeat offenders — intensive supervision traded for treatment-focused resolutions. Eligibility is discretionary and early advocacy matters.
  • Interlock starts immediately. Most judges order interlock as a bond condition on a second arrest, months before any conviction. Budget for it and comply perfectly — violations become leverage for the prosecutor.
  • No nondisclosure. While some first-time Class B convictions can eventually be sealed, second-offense convictions cannot. Avoiding the conviction matters more than ever.

The third-strike calculation

Every decision on a second DWI should be made with the third in mind: a third DWI is a third-degree felony with 2–10 years in prison. A reduction now — even to another misdemeanor — changes what the next arrest could become.
