Second DWI Offense in Texas
A second DWI in Texas is a Class A misdemeanor carrying 30 days to one year in county jail and a fine up to $4,000, with a minimum jail term a court cannot waive on a conviction and an ignition interlock requirement. Deferred adjudication is not available on a second DWI.
That last sentence is why a second case is a different animal from a first. The safety net most first-time defendants rely on is gone, which means the work has to happen earlier and the case has to be built as though it is going to trial — because sometimes that is the only path to an outcome you can live with.
What makes a prior count
Texas has no lookback period for DWI enhancement. A conviction from 1998 counts the same as a conviction from last year. Out-of-state convictions can count if the offense is substantially similar to Texas DWI, and that similarity is not automatic — it is an argument.
The prior itself is also attackable. If you pled guilty years ago without a lawyer, or without a valid waiver of counsel, or the judgment is defective on its face, that prior may not be usable to enhance the current charge. We pull the underlying judgment in every second-offense case. People are frequently surprised by what is in it.
What happens immediately
Two clocks start at arrest. You have 15 days to request an Administrative License Revocation hearing or your license is suspended automatically, with no conviction required. On a second offense the suspension periods are longer than they were the first time. Bond conditions in Tarrant County commonly include an ignition interlock device, alcohol monitoring, and a no-alcohol condition — violating any of those can land you back in custody before the case is ever resolved.
How second-offense cases are defended
Everything that applies to a first DWI still applies: the legality of the stop, the administration and scoring of field sobriety tests, the blood warrant affidavit, the lab work, and whether the State can tie operation and intoxication to the same moment in time. On a second case we add the attack on the prior conviction, and we plan for trial from the first week rather than the third month.
Realistic outcomes include dismissal, reduction to a lesser offense such as obstruction of a highway, and negotiated resolutions that avoid the minimum jail term. What is achievable depends on the evidence, and we will tell you honestly what we see once we have the discovery.
