A first-offense DWI case in Texas usually takes anywhere from three months to over a year from arrest to resolution. How long does a DWI case take in Texas in your specific situation depends on whether it ends in a plea agreement or goes to trial, how backed up the local court and crime lab are, and whether the charge is a misdemeanor or a felony. Cases with contested evidence, serious injuries, or felony-level allegations routinely stretch past eighteen months.
The Early Deadlines That Move Fastest
The first clock has nothing to do with the courtroom. Texas runs two separate tracks after a DWI arrest: the criminal case in court and an administrative process through the Texas Department of Public Safety called Administrative License Revocation, or ALR. The administrative side moves faster and has tighter deadlines than the criminal case.
If you failed a breath test or refused to provide a specimen at the time of arrest, you have 15 days from the date the notice was served to request an ALR hearing. If law enforcement took a blood sample instead, the deadline is 20 days from the date the suspension notice was mailed. Miss that window and your license suspension automatically starts on the 40th day after the notice was served, with no chance to contest it.1Department of Public Safety.

Requesting the hearing on time puts the suspension on hold until the hearing takes place. For a first offense, the suspension itself runs 90 days if you failed a chemical test and 180 days if you refused. A second or subsequent offense doubles those to one year and two years.2Department of Public Safety. Section 19 – Administrative License Revocation (ALR)
Bail conditions can also include an ignition interlock device, and a magistrate is required to order one if you have a prior DWI or the charge involves intoxication assault or intoxication manslaughter, unless imposing it is not in the best interest of justice.3State of Texas.

The Pre-Trial Phase Is Where Most Time Goes
Once the early deadlines are handled, the case shifts into its slowest phase. This stage alone commonly runs three to nine months, and it is where most of the total timeline accumulates.
It starts with an arraignment, where the charge is formally read and you enter a plea. Nearly everyone pleads not guilty at this point, even if a plea deal is the eventual goal, because it preserves options while the defense reviews the evidence. After arraignment, the defense requests everything the state has through discovery: police reports, dashcam and bodycam video, breath or blood test results, and the officer’s probable cause affidavit.
The defense is looking for procedural problems. Was the traffic stop legally justified? Were field sobriety tests administered correctly? Was the breath-testing equipment properly calibrated? Did the blood draw follow required protocols? Where something was mishandled, the defense files a motion to suppress asking the judge to exclude that evidence before trial. Briefing and arguing those motions adds weeks or months.
Blood test results are one of the most common sources of delay. Texas crime labs carry significant backlogs, and results can take several months to come back. In some counties, waits of over a year have been reported. Until the results arrive, neither side can make informed decisions about resolution, so the case stalls.
Expect the case to be reset multiple times during this phase. Each reset pushes the next court date out by several weeks. This is normal. Courts reset cases to allow time for discovery, motion practice, and negotiation. Four or five resets before resolution is unremarkable.
Plea Deals Move Faster Than Trials
The overwhelming majority of Texas DWI cases resolve through plea negotiations rather than trial, and that is the main reason so many cases finish inside a year. How long negotiations take depends on the strength of the evidence, your prior record, and the individual prosecutor. In a straightforward first-offense case with a BAC just above 0.08 and no accident, a plea offer may come relatively early. In a case with contested evidence or aggravating factors, negotiations can drag through multiple court settings.
For first-time offenders, Texas also allows deferred adjudication community supervision. You plead guilty or no contest, but the judge withholds a final conviction and places you on a supervision period with conditions like alcohol education, community service, and check-ins. Complete everything and the charge is dismissed without a final conviction. Deferred adjudication extends the overall involvement with the court by the length of the supervision period, which is a trade many defendants accept to avoid a conviction. Even a dismissed charge through deferred adjudication still appears on your record unless you later petition successfully for nondisclosure, which has its own eligibility requirements and waiting periods.
If negotiations break down, the case is set for trial, and this is where timelines can balloon. Getting a trial date depends heavily on court congestion. Urban counties with packed dockets may not have an opening for months after a case is declared ready. A jury trial itself typically takes one to three days for a misdemeanor DWI, though complex cases run longer. It includes jury selection, opening statements, testimony and cross-examination, physical evidence, and closing arguments. If the jury returns a guilty verdict, sentencing may happen the same day or be set for a later hearing.
Why Felony DWI Cases Take Longer
A third DWI offense, intoxication assault, and intoxication manslaughter are felonies in Texas. Add several months to every estimate above. Felony cases must be presented to a grand jury for indictment before they can proceed to trial, and the grand jury process alone can take one to several months depending on how often the grand jury convenes in that county.
Felony cases also involve more complex evidence, more witnesses, and longer trials. An intoxication manslaughter case may require accident reconstruction experts, toxicology testimony, and extensive medical records. These cases routinely take one to two years or longer to reach resolution.
What Makes One Case Faster Than Another
Several variables explain why one person’s DWI wraps up in four months while another’s drags past a year:
- County caseload. Courts in large metropolitan areas like Harris, Dallas, and Bexar counties carry enormous dockets. A case in a smaller rural county may move in half the time.
- Evidence delays. Waiting on blood test results from the state crime lab is the single most common bottleneck. If the lab is also screening for drugs beyond alcohol, the wait gets longer.
- Case complexity. A DWI involving a crash, injuries, or a BAC well above 0.15 takes longer because there is more evidence to gather and more legal issues to litigate.
- Defense strategy. Suppression motions, challenges to breath-testing equipment, and requests for independent blood testing all add time but may produce a better outcome.
- Prosecutor workload. An overloaded prosecutor’s office takes longer to extend plea offers and respond to motions.
The constitutional right to a speedy trial exists but rarely helps in practice. Texas courts apply the four-factor test from Barker v. Wingo, weighing length of delay, reason for it, whether the defendant demanded a speedy trial, and whether the delay caused actual harm to the defense. Routine delays of several months for lab work and negotiations do not come close to a constitutional violation. Asserting the right early and on the record matters if delay becomes extreme, but it seldom leads to dismissal.
After the Case Ends
Sentencing day is not necessarily the end of the process. If you were convicted at trial and believe legal errors affected the outcome, notice of appeal must be filed within 30 days of sentencing. Appeals do not involve new evidence or a second trial; the appellate court reviews the trial record for legal mistakes. The appellate process itself typically takes six months to over a year, adding to the total timeline well beyond the original proceedings.
Even without an appeal, there are follow-on steps that keep the case tied to your life for a while. You will need to reinstate your driver’s license through DPS, which involves paying reinstatement fees and completing any required education programs. Texas charges annual surcharges for three years following a DWI conviction to keep your driving privileges active.
