DWI Lawyer San Antonio: What a Texas First Offense Actually Means

A DWI lawyer San Antonio drivers call after an arrest on Loop 410 or outside a Pearl District bar usually hears the same reassurance from the client. It was a first offense, so it cannot be that serious. Texas disagrees. A first DWI is a misdemeanor, but it carries mandatory jail time on conviction, a separate state fine on top of the court’s fine, and an administrative license suspension that starts before the criminal case is decided. Understanding what the statute actually says is the first step in deciding how to respond to a Bexar County DWI charge.

What Texas Means by Intoxicated

Texas Penal Code Section 49.01 defines intoxication two ways. The first is not having the normal use of mental or physical faculties because of alcohol, a drug, or any combination. The second is an alcohol concentration of 0.08 or more. Prosecutors only need one. So a driver who blew under 0.08 still faces a charge on the faculties definition, and a driver who blew 0.09 faces one even if every field sobriety test went well. That two-track definition is why San Antonio DWI cases rarely come down to a single number.

What a DWI Lawyer San Antonio Residents Hire Sees in a First-Offense Charge

Section 49.04 makes a first DWI a Class B misdemeanor with a minimum term of 72 hours in confinement. Under Penal Code Section 12.22, a Class B carries up to 180 days in county jail and a fine up to $2,000. Two facts move a first offense up a level. An open container in the driver’s immediate possession raises the minimum confinement to six days. Meanwhile, an alcohol concentration of 0.15 or more makes the charge a Class A misdemeanor. Under Section 12.21, that means up to a year in jail and a fine up to $4,000. In Bexar County, the County Courts at Law hear misdemeanor DWI cases rather than the district courts. Arizona takes a different approach, as our guide to Arizona DUI penalties explains, but the Texas structure is what applies here.

The State Fine Most Drivers Have Never Heard Of

Texas repealed its Driver Responsibility surcharge program in 2019. It replaced it with a fine that sits in the Transportation Code rather than the Penal Code. Section 709.001 requires a person finally convicted of DWI to pay $3,000 for a first conviction within a 36-month period. A second conviction in that window costs $4,500. Any conviction with a proven alcohol concentration of 0.15 or more costs $6,000, first offense or not. The court must waive the fine on a finding of indigence, which the statute ties to income at or below 125 percent of the federal poverty guidelines or enrollment in listed assistance programs. This fine is in addition to the criminal fine, court costs, and any probation fees.

Deferred Adjudication and the Interlock Condition

Texas reopened deferred adjudication for first-offense DWI in 2019. Code of Criminal Procedure Article 42A.102 allows it for a Section 49.04 charge unless the driver held a commercial license at the time or the alcohol concentration was 0.15 or more. A successful deferred adjudication ends without a conviction on the criminal record, though the arrest record itself remains. Article 42A.408 governs ignition interlock. The court must order a device when the concentration was 0.15 or more or the driver has a prior. That device then stays installed for at least half the supervision period. Courts may also order one as a discretionary condition in other first-offense cases.

The License Case a DWI Lawyer San Antonio Drivers Hire Handles First

A DWI arrest also triggers an administrative license revocation case that has nothing to do with guilt or innocence. Under Transportation Code Chapter 524, a failed breath or blood test leads to a 90-day suspension for a driver with no alcohol-related contact in the prior ten years. A refusal under Chapter 724 leads to a 180-day suspension. The driver has 15 days from the notice to request a hearing. Miss that window and the suspension takes effect on the 40th day whether or not prosecutors ever prove the criminal case. This deadline arrives long before the first court date.

Repeat Offenses: Why a DWI Lawyer San Antonio Drivers Hire Asks About Priors

Section 49.09 turns a second DWI into a Class A misdemeanor with a minimum of 30 days in confinement. A third DWI becomes a third-degree felony. So does a second offense when the prior was intoxication manslaughter. Under Section 12.34, a third-degree felony carries two to ten years in prison. Texas does not wash out old DWI convictions for enhancement purposes. A conviction from fifteen years ago still counts.

The Bottom Line

A first Texas DWI is a misdemeanor with felony-style consequences attached: mandatory confinement, a separate state fine of $3,000 or more, a possible interlock, and a license suspension with a 15-day fuse. Because the criminal case and the license case run on different calendars, the earlier one closes first. Neither one guarantees an outcome. What a DWI lawyer San Antonio drivers retain can do is examine the stop, the testing, and the timeline before any of those consequences become permanent.
