Texas Federal DWI Attorneys

Most DWI arrests in Texas are prosecuted in state court under Texas Penal Code §49.04. When a DWI occurs on federal property (ex. a military installation, a national park, a federal building, or other land under federal jurisdiction) the case is processed differently. It is prosecuted in federal court, handled by federal prosecutors and federal magistrate judges, and governed by federal procedure rather than Texas state court rules.

What does not change is the underlying law. Under the Assimilative Crimes Act (18 U.S.C. §13), a DWI committed on federal land is prosecuted under the state law that would apply if the offense had occurred off federal property. In Texas, that means Texas Penal Code §49.04. The substantive elements, the BAC standard, and the forensic science challenges are all the same. The forum is different.

Deandra Grant Law defends federal DWI charges in North and Central Texas. Managing Partner Deandra Grant holds a Master’s Degree in Pharmaceutical Science, a Graduate Certificate in Forensic Toxicology, and the ACS-CHAL Forensic Lawyer-Scientist designation. She is a trained SFST instructor who administers and grades both the ACS-CHAL Forensic Lawyer-Scientist and DUIDLA Board Certification exams. The forensic science challenge in a federal DWI case is identical to what applies in state court and it is conducted at the same scientific level.

The Assimilative Crimes Act: How Federal DWI Works

18 U.S.C. §13 provides that whoever within or upon any federal enclave is guilty of any act or omission which, although not made punishable by any enactment of Congress, would be punishable if committed within the jurisdiction of the state in which such place is situated, shall be guilty of a like offense and subject to a like punishment.

The practical effect: a DWI on a military installation in Tarrant County is prosecuted using Texas Penal Code §49.04, but in federal court rather than the Tarrant County courts where Tarrant County DWI cases are heard. The federal magistrate judge presiding over the case is applying Texas DWI law. The government’s burden of proof is the same. The BAC threshold (0.08% per se, or impairment regardless of BAC) is the same. The available defenses are the same.

What changes is the procedural setting. Federal court procedures, federal rules of evidence, and federal sentencing provisions govern how the case moves through the system.

Where Federal DWI Charges Arise in North and Central Texas

The following federal properties within the DGL service area generate federal DWI charges:

• Naval Air Station Joint Reserve Base Fort Worth (NAS JRB): One of the largest joint reserve bases in the country, located in Fort Worth. Offenses on base property are prosecuted in the Northern District of Texas.
• Fort Hood: The large Army installation near Killeen in Bell County. Within the Western District of Texas.
• Dyess Air Force Base: Abilene. Northern District of Texas.
• Sheppard Air Force Base: Wichita Falls. Northern District of Texas.
• Lake Texoma and other Army Corps of Engineers recreation areas: Federal land along major reservoir shorelines generates DWI enforcement, particularly on holiday weekends.
• National Park Service lands: Including portions of the Guadalupe Mountains and Big Bend (Western District) and national recreation areas.
• Other federal enclaves: Federal buildings, post offices, VA medical centers, and other federally owned property can fall under the Assimilative Crimes Act if a DWI occurs on the property itself.

Penalties for Federal DWI Under the Assimilative Crimes Act

Because federal DWI assimilates Texas law, the penalty structure mirrors the Texas DWI penalty structure for the equivalent offense level:

• First offense (Class B misdemeanor): Up to 6 months in federal custody, fine up to $5,000 under federal sentencing, and the Texas-equivalent penalties assimilated through the ACA. Probation is available.
• Second offense: Enhanced penalties consistent with the Texas second-offense Class A misdemeanor structure.
• Third offense (felony): Federal felony treatment consistent with the Texas third-offense felony structure.
• DWI with child passenger, intoxication assault, intoxication manslaughter: Each of these Texas offense-level escalations is assimilated into the federal prosecution at the equivalent level.

Federal misdemeanor DWI cases are typically heard by a United States Magistrate Judge rather than a District Court Judge. The defendant has the right to have the case heard by a District Court Judge if they request it, which may affect the strategic posture of the case.

The ALR Process and License Consequences

One procedurally significant difference between state and federal DWI cases is the Administrative License Revocation process. In a Texas state DWI case, the arresting officer issues a DIC-25 notice, triggering the 15-day ALR deadline. In a federal DWI case on federal property, the Texas DPS ALR process may not be automatically triggered in the same way.

However, a federal DWI conviction will be reported to Texas DPS and will result in license consequences consistent with the Texas offense level assimilated by the ACA. The specific mechanism for license suspension in federal DWI cases should be evaluated at the outset of representation. The absence of an automatic ALR notice does not mean there are no license consequences.

The Forensic Science Defense in Federal DWI Cases

The forensic science challenges available in a federal DWI case are the same as in any Texas DWI prosecution, because the same Texas DWI law is being applied:

Breath testing.  The Intoxilyzer 9000 calibration records, observation period compliance, partition ratio variability (1,100:1 to 3,400:1 across the population), and instrument-specific maintenance history are all subject to challenge. Breath test challenges in federal court proceed under the federal rules of evidence, which generally follow the same principles as Texas evidentiary rules for scientific evidence.

Blood draws.  Chain of custody from collection through laboratory analysis, GC-FID methodology (for ethanol), in vitro fermentation from improper storage, sodium fluoride preservative adequacy, and analyst qualifications are all subject to independent review. A blood draw performed by a military medical facility or federal agent rather than a civilian medical professional may have different chain of custody documentation that warrants specific examination.

Field sobriety tests.  SFST administration on federal property may involve military law enforcement or federal park rangers rather than Texas peace officers. The same NHTSA protocol applies regardless of who administered the tests. Deandra Grant is a trained SFST instructor (she administers and grades the ACS-CHAL Forensic Lawyer-Scientist and DUIDLA Board Certification exams) which means SFST cross-examination goes to the specific protocol deviations, not just whether the officer was certified.

Retrograde extrapolation.  The same Widmark formula, elimination rate variability, and rising BAC defense analysis that applies in state court applies in federal court. The pharmacokinetic challenge requires the same graduate-level pharmaceutical science training regardless of the forum.

Texas Federal DWI Attorneys Client Story

This client story is for educational purposes only.

Kenneth never thought he’d end up in the situation he found himself in that cold evening. He had been on his way home from visiting family at the Naval Air Station Joint Reserve Base in Fort Worth when he was pulled over by federal officers. What started as a routine stop quickly escalated into something far more serious—he was arrested for Federal DWI.

In an instant, Kenneth’s life seemed to crumble. A Federal DWI charge was no small thing. He knew the penalties were severe—fines, imprisonment, the loss of his driver’s license. Worse, the thought of being branded with a permanent criminal record weighed heavily on him. How would he explain this to his employer, his friends, and his family? What if his career was ruined?

The night he sat in jail, Kenneth felt helpless. He didn’t know where to turn or what to do. But one thing kept running through his mind: he couldn’t give up. He had to fight this.

The next morning, Kenneth decided to make the call that would change everything.

He reached out to Deandra Grant Law, hoping for a glimmer of hope. What he found was much more than that—he found a team that understood the weight of his situation and was ready to fight for his future.

Deandra Grant, a highly skilled Texas Federal DWI Attorney, took Kenneth’s case personally. From the moment they sat down together, Kenneth felt a weight lift off his shoulders. Deandra listened carefully, asked thoughtful questions, and reassured him that he was not alone in this battle.

“I understand how you feel, Kenneth,” she said. “We’ve handled cases like yours before. The federal system is complex, but we know how to navigate it. We will do everything we can to protect you.”

Deandra immediately got to work. She knew that Federal DWI cases involved a unique set of challenges, especially with the Assimilative Crimes Act coming into play. Deandra’s years of forensic DWI knowledge made her the ideal attorney to challenge the evidence in Kenneth’s case. She didn’t just rely on the surface-level facts—she dug deeper.

Through her meticulous examination, she discovered flaws in the procedures the officers used during the arrest. The breathalyzer test wasn’t administered properly, and the field sobriety tests were conducted under questionable circumstances. Deandra presented this evidence in court with confidence, showing the jury that Kenneth’s arrest was not handled according to the law.

In the end, Kenneth was found not guilty of all charges. The weight that had burdened him for so long was finally lifted. The sense of relief Kenneth felt was overwhelming. Not only had he avoided prison time and a criminal record, but his life was back on track.

“I can’t believe it,” Kenneth said, tears in his eyes after the verdict was read. “I thought everything was lost, but Deandra Grant Law gave me hope when I had none. I owe everything to her.”
