The initial stop
The defense should examine the facts police relied upon to stop or detain the driver.
DWI Defense
A DWI case is built from a sequence of decisions, observations, tests, and evidence.
A Texas DWI arrest can involve the traffic stop, officer observations, field sobriety testing, breath or blood evidence, video, statements, and separate driver-license issues. The defense should examine how those pieces fit together before accepting the State’s version of events.

At a Glance
A DWI charge asks whether the State can prove intoxication while operating a motor vehicle in a public place.
Texas DWI cases are highly fact-specific. The defense may involve the reason for the stop, the officer’s observations, the meaning and administration of field sobriety exercises, chemical-test evidence, video, statements, warrants, and whether the complete record supports the conclusions in the police report.
The practical question
What does the evidence actually show about the driving, the encounter, the testing, and the State’s claim that the accused was intoxicated?
What Can Shape the Case
Six parts of a DWI case that deserve careful review.
Officer observations
Speech, balance, appearance, driving, conduct, and other observations should be compared with recordings and surrounding circumstances.
Field sobriety testing
Instructions, administration, conditions, physical limitations, and video may affect how roadside exercises are evaluated.
Breath or blood evidence
Collection procedures, testing records, timing, laboratory information, and other technical evidence may require review.
Video evidence
Dash-camera and body-camera recordings can provide context that may confirm, qualify, or conflict with written reports.
Enhancement issues
Prior history and other alleged circumstances can affect the accusation and should be verified carefully.
The Questions That Come First
The defense should test the investigation from the beginning—not start with the assumption that the arrest was correct.
A DWI investigation develops in stages. Each stage can produce evidence, and each stage can raise factual or legal questions that affect the case.
Why was the vehicle stopped?
The facts supporting the stop or detention should be identified and evaluated.
What does the video show?
Recordings may provide important context for driving, speech, movement, instructions, testing, and officer observations.
How were tests administered?
The circumstances surrounding roadside exercises and chemical testing should be reviewed rather than reduced to a conclusion in a report.
Are there separate deadlines or restrictions?
A DWI arrest can involve issues outside the criminal prosecution, including driver-license matters that may be time-sensitive.
What to Do Now
Preserve the evidence and address deadlines before the case moves forward.
Preserve records and video
Identify recordings, receipts, messages, location information, witnesses, and other potentially relevant evidence.
Address license issues
Determine whether the arrest created a separate driver-license process or deadline requiring attention.
Avoid discussing the facts publicly
Posts, messages, and unnecessary statements can create additional evidence or confusion.
Review the complete investigation
Compare the police narrative with video, testing, records, and the legal requirements of the charged offense.
Our Process
A DWI defense developed from the stop through the evidence.
Analyze the encounter
Review the alleged driving conduct, stop, detention, investigation, arrest, and procedural history.
Collect the evidence
Obtain and organize recordings, reports, testing records, warrants, laboratory information, and other available material.
Identify disputed issues
Evaluate factual inconsistencies, evidentiary questions, constitutional issues, and weaknesses in the State’s proof.
Prepare the case
Develop the strategy for negotiations, motions, hearings, trial preparation, or other appropriate case decisions.
Strategy
The police report is one account of the investigation. The evidence is the case.
A DWI defense should not be limited to reading the arresting officer’s conclusions. The underlying recordings, testing information, chronology, observations, and procedures may provide a more complete picture.
The goal is to determine what the State can actually prove and identify the factual and legal issues that matter before important decisions are made.
Frequently Asked Questions
DWI defense questions.
Is a DWI arrest the same as a conviction?
No. An arrest is an accusation. The prosecution still has the burden of proving the charged offense.
What does Texas law generally require for DWI?
Texas Penal Code Section 49.04 generally addresses operating a motor vehicle in a public place while intoxicated. The application of the statute depends on the facts of the individual case.
Can breath or blood evidence be challenged?
The collection, testing, documentation, timing, and other circumstances surrounding chemical evidence may be relevant and should be reviewed in the individual case.
Can video matter in a DWI case?
Yes. Dash-camera and body-camera recordings may provide evidence concerning the driving, investigation, field exercises, statements, and officer observations.
Why should a DWI case be reviewed early?
Evidence may need to be preserved and a DWI arrest can create separate driver-license issues with time-sensitive procedures.
DWI Defense Consultation
A DWI case should be reviewed before the State’s version becomes the only version being considered.
The Piri Law Firm can review the stop, investigation, recordings, field testing, chemical evidence, alleged enhancements, procedural posture, and available defense issues.
