Will I Go to Jail for a First DWI in Austin?

The Direct Answer: Jail Is Possible, but Outcomes Vary

For a first-offense DWI in Austin, Texas law sets a range of 72 hours to 180 days in jail. The statutory range and the actual outcome in a given case can be very different. Depending on the facts, criminal history, and disposition, a first-offense case may resolve through dismissal, a reduced charge, community supervision, deferred adjudication in some qualifying cases, or a sentence that includes jail time. The Travis County Attorney’s Office prosecutes misdemeanor DWI, and plea offers depend on the evidence and the defendant’s history. An experienced Austin DWI attorney evaluates the evidence first, because the right strategy depends on what the evidence supports.

The Penalty Range for a First DWI in Texas

A standard first-offense DWI in Texas under Penal Code §49.04 is generally a Class B misdemeanor. The statutory range is:

• Minimum: 72 hours of confinement
• Maximum: 180 days in jail
• Fine: Up to $2,000
• License consequences: Criminal-case license suspension on conviction, plus separate ALR consequences through Texas DPS

Under Penal Code §49.04(d), a DWI with an alcohol concentration of 0.15 or more at the time the analysis was performed is a Class A misdemeanor, prosecuted by the same Travis County Attorney’s Office with a higher range: up to 1 year in jail and a $4,000 fine. Ignition-interlock requirements may apply depending on the BAC allegation, disposition, and court.

Time already served after arrest may be credited toward confinement in some cases. Whether any additional jail time is imposed depends on the disposition and the court.

How Travis County Handles First-Offense DWI Cases

The Travis County Attorney’s Office prosecutes misdemeanor DWI, including first and second offenses, and cases are heard at the Blackwell-Thurman Criminal Justice Center at 509 W. 11th Street. Here is how a first offense can develop:

Without representation: A person may receive a plea offer without a full review of the stop, testing, and video evidence. A plea can involve community supervision, fines, alcohol education, a victim impact panel, and community service. The record consequences depend on the disposition. Some qualifying DWI cases may be eligible for deferred adjudication, while others are statutorily excluded.

With experienced representation: An Austin DWI attorney evaluates the traffic stop for Fourth Amendment issues, examines the Intoxilyzer 9000 maintenance records and BAC evidence, reviews the SFST administration on video, and addresses the ALR deadline. When the evidence supports it, issues with the stop, breath test, or SFSTs can support suppression motions or dismissal. A dismissal may make the arrest eligible for expunction under Texas Chapter 55, depending on the circumstances.

Deferred Adjudication and Nondisclosure for DWI in Texas

Many people who ask “will I go to jail?” are also concerned about their record. Both questions matter.

Deferred adjudication may be available for some qualifying DWI offenses under Code of Criminal Procedure Art. 42A.102, but statutory exclusions apply. Exclusions include certain cases involving a BAC of 0.15 or higher, a commercial driver’s license or commercial learner’s permit, repeat-offense enhancement, and specified intoxication offenses. Eligibility depends on the exact charge, BAC allegation, prior history, commercial license status, and other factors.

Some qualifying DWI dispositions may be eligible for an order of nondisclosure. Eligibility depends on the offense level, BAC, prior history, accident circumstances, disposition, waiting period, and other statutory requirements. Nondisclosure is not the same as expunction.

A DWI conviction can still carry significant consequences:

• It generally remains part of criminal history unless a specific record-relief statute applies
• It can be used to enhance a future DWI charge
• It can affect insurance, including SR-22 requirements in some cases
• It can affect commercial driving privileges
• It can prompt review by professional licensing boards in some fields

Factors That Affect Jail Exposure on a First Austin DWI

Not all first DWIs are equal. Several factors can affect how the Travis County Attorney’s Office evaluates a case:

BAC of 0.15 or above. This can elevate the charge to a Class A misdemeanor with a higher maximum and possible ignition-interlock requirements.

An accident. If the arrest followed a crash, the case may be evaluated differently. If there was serious bodily injury, the case may be referred to the Travis County District Attorney as intoxication assault, a third-degree felony.

A child in the vehicle. DWI with a child passenger under 15 is a state jail felony under Penal Code §49.045, even on a first offense, and is prosecuted by the Travis County District Attorney’s Office rather than the County Attorney.

Prior criminal history. Even without a prior DWI, other criminal history can affect how the file is evaluated.

Conduct at the scene. Statements and conduct during the stop can affect the prosecution’s assessment of the case.

The 15-Day ALR Deadline

Separate from the jail question, the Administrative License Revocation process has a short deadline. Texas DPS generally requires an ALR hearing request within 15 days after the person is served with the suspension notice. The DIC-25 or other applicable notice should be reviewed to confirm the deadline. In some blood-test cases, the notice of suspension may arrive later, after the lab result.

If a timely hearing request is not made, the suspension can take effect as stated in the notice. For a first offense, the ALR suspension is generally 90 days for a qualifying test failure and 180 days for a refusal. When representation includes the ALR proceeding, The Hull Firm acts promptly to request the hearing before the applicable deadline. Learn more about first-time DWI defense in Austin.

Evidence Issues That Can Affect a First DWI Case

The strength of the prosecution’s case depends on the evidence. These are areas an Austin DWI lawyer commonly evaluates:

The stop or encounter. Many DWI cases begin with a traffic stop, while others arise from crashes, parked vehicles, or welfare checks. Under Rodriguez v. United States (575 U.S. 348, 2015), a traffic stop generally cannot be extended beyond its original purpose without independent reasonable suspicion. If the stop or detention violated the Fourth Amendment or Texas law, evidence obtained as a result may be subject to suppression under Texas Code of Criminal Procedure Art. 38.23. The effect depends on the facts and what independent evidence remains.

The field sobriety tests. HGN, Walk and Turn, and One Leg Stand are standardized tests with administration requirements. Instructions, surface conditions, and officer training records can be reviewed. The BAC and breath test defense page covers issues that can arise in Travis County.

The Intoxilyzer 9000 result. The instrument used for a breath test has maintenance, calibration, and error records that can be requested. Operator certification, maintenance history, and the observation period can be evaluated to determine whether a reliability or admissibility issue exists.

Blood draw evidence. Blood evidence can be reviewed for the warrant, collection procedure, chain of custody, preservation, and laboratory analysis. Whether a problem affects the result or its admissibility depends on its legal and scientific significance.

What Happens if the Case Is Not Dismissed

When dismissal is not available, other dispositions may be possible. For a first DWI, community supervision can involve:

• A period of community supervision, often 12 to 24 months
• A fine and court costs
• DWI education program completion
• Victim impact panel attendance
• Community service hours
• Possible ignition interlock device requirement

The record and license consequences depend on whether the disposition is a conviction, deferred adjudication, or another outcome. The firm evaluates dismissal, suppression, reduction, deferred adjudication where available, negotiated resolution, and trial based on the individual case.
