Every criminal case must be specific to the facts and the people involved. Your DWI charges are different from other defendants’ cases; it is imperative that your legal defense consistently works to meet your particular requirements while prevailing. Knowing the defense at your disposal is the only way to accurately plan tactics and bring your case to the most advantageous conclusion possible.
If you were arrested in Harris County, it’s critical to understand the legal framework that governs your case before taking any action. This is truer still for Harris County DWI cases since any time in custody would be spent in the Harris County Jail system, usually in one of the main downtown jail facilities in Houston, Texas.
In reality, Texas DWI law is defined under Texas Penal Code §49.04. This makes it illegal to operate a motor vehicle in a public place while intoxicated — meaning having a blood alcohol concentration (BAC) of 0.08% or higher, or lacking normal use of mental or physical faculties due to alcohol or drugs.

What Does Texas Penal Code §49.04 Say About DWI? Why It Is Hard to Say More
Under §49.04, a first-time DWI is usually a Class B misdemeanor — punishable by up to 180 days in jail and a fine of as much as $2,000. Typically if your BAC is 0.15% or higher, it can be filed as a Class A misdemeanor, bringing up to a year behind bars and $4,000 in fines.
In Harris County, such cases are usually tried at Harris County Criminal Justice Center, 1201 Franklin St., Houston, TX 77002. They are assigned in the County Criminal Courts-at-Law Nos. 1–16. Upon arrest, all your information becomes public information through the Harris County District Clerk’s Office, which also manages your court docket and bond conditions.
Immediate Steps to Take After a DWI Arrest in Houston
Once you have been nabbed for DWI in Harris County, the countdown begins. One of the first orders of business is to do everything possible to protect your right to drive legally; it also means taking hold of any and all damning evidence that might be used against you.
If You Have Not Heard from the ALR Section After 20 Days
Texas Transportation Code §524.031 explicitly states that once you receive notice that DPS intends to suspend your license because of a failed or refused breath or blood test, you generally have 15 days from the date you received that notice to request an ALR hearing.
If you let the time go by, your driver’s license will be automatically suspended. So act now and either hire an attorney to represent you, or go online to the DPS’s web site and submit your demand online.

Preserving Evidence Early (Left: Dash-Cam, Right: Body-Cam, Lab Data)
In Houston, HPD patrol cars and DWI task force units often tape the entire stop and field-sobriety exercise. Preserving this footage—along with breath-test calibration logs and lab chain-of-custody forms—can make or break your case.
Jim Butler’s team obtains these data through subpoenas and discovery requests as quickly as possible after someone is arrested for allegedly driving while intoxicated, in order to establish a true record before much of the evidence is officially lost or overwritten.
Top DWI Defense Strategies to Use in Texas
Every strong defense against DWI or any other crime consists of finding flaws within the state’s evidence. A careful review of probable cause, testing reliability, and procedure forms the basis for each case, and summaries into such as pertain to particular areas can typically follow thereafter.
First Attacking the Traffic Stop
Before police put you in handcuffs, they must have reasonable suspicion to pull you over and then probable cause to arrest you. If a Houston Police Department or Harris County Sheriff’s deputy stopped you by means not only somewhat overbearing but illegal—for instance, without having seen any specific traffic violations committed or any other articulable facts—then your attorney can file a Motion to Suppress under Texas Code of Criminal Procedure Article 38.23, Texas’ exclusionary rule.

Subpoenaing Video Data from DWI Squad Cars and HPD’s Breath Testing Logs on Lab Data and On-Site Blood Tests
DWI all too often turns on the admissibility of test results. While lawyers are wise to play their case in a court of law, laying it out to both judge and jury is where we hope they will eventually flourish.
When your defense team arrives on the scene to investigate it, they are trained to see things differently than most witnesses might because they know what questions need to be asked. Detailed on-road observation reports often accompany defense requests for breath and blood test results in Texas. If the State delays or key records never show up, that can become part of the defense strategy in pretrial hearings.
Examples of problems include:
- Samples of blood that are contaminated or a breach in the chain of custody.
- Field sobriety tests that are administered improperly.
Field Sobriety Tests and Officer Mistakes
Under NHTSA criteria, only three standardized field examinations are accepted when properly administered: Horizontal Gaze Nystagmus (HGN), Walk-and-Turn, and One-Leg Stand. Many Houston-area cops don’t proceed in this fashion, which can weaken how much weight those tests should carry in court.

Medical and Environmental Influences on BAC
Numerous health conditions can send false positives or exaggerated readings to breathalyzer tests, such as acid reflux (GERD), diabetes (ketoacidosis), or hypoglycemia. Even mouthwash or dental work can throw off readings. An experienced DWI attorney in Houston can subpoena calibration and device records plus attestation from operators in order to show these matters.
The Failure of Police To Read Miranda Rights
If an officer failed to tell you your rights after he or she had you in custody or let slip that pressures were being exerted in examination, the Fifth Amendment and Texas Code of Criminal Procedure Art. 38.22 might allow those statements to be excluded from evidence.
Harris County district attorneys often depend on body-fitted camera film (if usable) to demonstrate they followed required processes—if such film doesn’t exist or shows clear breaches, then your defence is able to move for removal of those statements as evidence in whole or in part.
The Role of a DWI Attorney in Houston
Without a lawyer who understands local court dynamics and Harris County procedures, even the most successful DWI defense strategies run into a stone wall. Each courtroom at 1201 Franklin St. has its own culture, docket pace and approach to plea deals.
Why Experience at Harris County Courts Counts
Attorney Jim Butler has defended DWI cases alone for over 30 years. He knows the prosecutors, judges and pre-trial intervention programs of Harris County (PTI) very well, so he can either negotiate or contest cases strategically. For instance, it makes a difference that some judges in the County Criminal Courts may be more open to deferred adjudication or flexible bond conditions for first offenders, while others are stricter about ignition interlock and other terms.
Questions to Ask When Hiring a DWI Attorney
Before hiring a potential Houston DWI lawyer, ask:
- How many Harris County DWI cases have you handled?
- Do you handle both the ALR hearing and criminal case together?
- How quickly can you preserve video evidence from HPD or HCSO?
- Have you successfully filed motions to suppress based on bad stops or testing errors?

Plea Bargains, Reductions, and Dismissals
Not every DWI case in Texas ends in a trial. Some cases can be reduced, dismissed or pleaded out – it all depends on the strength of evidence and the accused’s prior record.
How Plea Bargaining Works in Harris County
In borderline evidence situations or when procedural issues come up, plea bargains are commonplace. For example, a BAC around 0.08–0.09% with no crash or prior offenses may sometimes be worked down into Obstruction of Highway or Passageway; a non-alcohol-labeled misdemeanor. It depends heavily on the facts and the court.
Deferred Adjudication
Under Texas Code of Criminal Procedure Chapter 42A (the community supervision chapter), some first-time DWIs may be offered deferred adjudication, subject to eligibility rules and prosecutor/judge discretion. This can prevent you from getting a final conviction on your record if you successfully complete supervision.
Motions to Suppress and Dismiss in Court
For situations when the Fourth Amendment is violated by evidence, it can be kept away from trial in a Motion to Suppress. When granted, prosecution may have nothing left.

How to Prepare for Court: Inside the Houston Jail Process
Every Harris County DWI case follows clear legal steps, which will help reduce the amount of fear and confusion that one experiences.
From Arraignment to Trial
A not guilty plea could be entered by your attorney and pre-trial motions started after a booking and an arraignment where formal charges are made.
During discovery, both sides exchange evidence–such as police reports, lab results, video footage examples.
Should the case go to trial, the defense could undercut the state’s case under reasonable doubt standards, often calling as their witness experts.
Expert Witnesses and Forensic Evidence
Expert testimony presents a large benefit to those charged with DWI in Houston. Forensic toxicologists, accident reconstructionists or field sobriety experts can finally reason that:
- BAC may have risen after driving (rising BAC), so a later test looks worse than the number at the time of driving, or
- Unit testing or maintenance had malfunctions and gaps,
- Important safety checks under NHTSA or DPS rules were not followed.
These kinds of details can be used to challenge the reliability of the State’s scientific evidence.
Post-DWI Remedies: Erasing or Sealing off Records
Even after a DWI case is over you may be able to modify your record, depending on what happened.
When Nondisclosure May Be Appropriate for a First DWI
Under Texas Government Code §411.0731, some first-time DWI offenders may qualify to have their records sealed from most public view through an order of nondisclosure. This means there is no mention of the conviction in most public background checks (though law enforcement and certain agencies can still see it).
Needed for eligibility often are:
- BAC below 0.15%,
- No accidents or injuries involving another person, and
- Completion of probation with interlock installation compliance if it was ordered.
As regards the time spans for these cases, the waiting period often ranges from about two years with an alcohol ignition interlock to about five years without one, depending on the statute and facts.
How To Seal Non-Convictions
If you were dismissed, no-billed or acquitted of a DWI charge, you may be eligible to expunge it under the Texas expunction statutes (historically found in Chapter 55 and now recodified in Chapter 55A of the Code of Criminal Procedure).
Once you have obtained expunction, the record will generally not appear as if you were ever arrested on most checks. It is typically filed after successful pretrial motions to suppress or when a case ends with a verdict of not guilty.

Frequently Asked Questions About DWI Defense Strategies
- Q: How long after a DWI arrest does the request for a driver’s license hearing have to be made?
A: You have fifteen days from the date of your notice of license suspension from DPS (Department of Public Safety) to file for an Administrative License Revocation (ALR) hearing in Texas. - Q: Can I get my DWI case dismissed in Harris County?
A: Yes, it is possible. When your lawyer shows evidence that there has been an illegal stop, faulty testing or procedural error, Harris County judges may suppress key evidence, and in some cases the district attorney’s office may dismiss the charges. Nothing is guaranteed—each case depends on its facts. - Q: What happens if I refuse to take the breath test or blood test?
A: Refusal itself will result in a license suspension under Texas’ implied consent laws, and officers may still seek a warrant for your blood. But without a breath or blood number, the State has less scientific data to rely on in your criminal case. - Q: Do I need an attorney for a first-time DWI offense?
A: Absolutely. First DWI arrests cause long lasting and sometimes irreversible damage. Attorneys like Houston’s Jim Butler are knowledgeable in the various options for diversion and local practices in Harris County and can generally help to minimize the penalties. - Q: Are field sobriety tests mandatory in Texas?
A: No. Field sobriety tests are voluntary, although refusing them may still result in your arrest based on other observations. However, refusal means that the prosecution will not have some of that test evidence to play for a jury. - Q: How does a DWI conviction affect my record?
A: A DWI conviction remains on your record permanently in Texas. Charges of some types, if not convicted, may be expunged or later sealed by nondisclosure, but a straight conviction is very hard to remove.
