Texas DUI & DWI Attorney

A Texas DWI arrest can threaten your driver’s license, freedom, employment and reputation. JP Law examines the stop, arrest, testing procedures, video, laboratory evidence and constitutional issues, then prepares the defense for negotiation, motions or trial.

Every criminal case is different. No result can be guaranteed, and this page provides general information rather than legal advice.

Why These Cases Are Different

A DWI Arrest Requires More Than a Quick Plea Decision

Texas generally uses the term Driving While Intoxicated, or DWI, for adult impaired-driving allegations. DUI is commonly associated with alcohol-related driving allegations involving minors, although people often use DUI and DWI interchangeably when searching for counsel.

A DWI charge is an accusation, not a conviction. The State must prove the required elements beyond a reasonable doubt, and the defense may challenge how the investigation began, how evidence was obtained and whether the evidence is reliable.

Texas DWI Law and Constitutional Rules Matter

Texas intoxication law, search-and-seizure protections, implied-consent procedures, evidentiary rules and driver-license regulations can all affect the defense.

Do Not Assume the Crash Report Tells the Whole Story

An officer’s report is only one account. Body-camera footage, dash-camera video, dispatch records, test records, laboratory documents, medical history and witness testimony may support, contradict or add context to that report.

The Criminal Case and License Case Are Separate

A DWI arrest may create two separate matters: the criminal prosecution and an Administrative License Revocation process involving driving privileges.

How Truck Crashes Happen

Common Texas DWI Defense Issues

A careful defense examines each stage of the investigation rather than assuming that a breath number, blood result or officer conclusion ends the case.

The Initial Traffic Stop

An officer generally needs a lawful basis to stop or detain a vehicle. Video and dispatch records may show whether the stated reason is supported.

Field Sobriety Testing

Standardized field sobriety tests depend on instructions, administration, scoring and conditions. Lighting, footwear, injuries, age, surface conditions, weather and communication can affect performance.

Breath Testing

Breath testing raises questions about observation periods, instrument maintenance, operator procedures, calibration, environmental interference and whether the reported result reliably reflects the relevant time.

Blood Testing

Blood evidence may involve the legal basis for collection, consent or warrant issues, chain of custody, storage, preservatives, laboratory methods, quality control and interpretation.

Drug-Related DWI Allegations

Prescription medications, over-the-counter products, controlled substances and medical conditions can produce allegations that require a different scientific analysis than an alcohol-only case.

Accidents, Injuries and Enhanced Charges

Crashes, alleged injuries, a child passenger, prior convictions or other circumstances can increase the seriousness of the accusation and the potential consequences.

Evidence Can Disappear

The Evidence That Can Shape a DWI Defense

DWI cases generate video, electronic and scientific records that should be requested and reviewed before important decisions are made.

01

Body Camera, Dash Camera and Digital Evidence

Body-camera and dash-camera footage may show driving behavior, speech, balance, instructions, test conditions, officer statements and the timing of events.

Why it matters

Digital evidence may reveal whether the written report accurately describes what happened and whether required procedures were followed.

Preservation priority

Video can be subject to retention rules, technical problems or incomplete recording.

Attorney action

Prompt requests can help identify and preserve footage from law enforcement, detention facilities and nearby businesses.

02

Officer Reports and Civilian Witnesses

Officer reports, dispatch audio, 911 calls, passengers and civilian witnesses may provide different accounts of driving, drinking, medication use, conduct or the crash.

Why it matters

Reports should be compared with recordings and physical evidence rather than accepted in isolation.

Preservation priority

Witness memories can fade, and contact information may become outdated.

Attorney action

Early investigation helps locate witnesses and preserve their observations.

03

Breath, Blood and Laboratory Evidence

Breath-test records, blood-test chromatograms, chain-of-custody documents, maintenance logs and laboratory quality-control materials can be important to evaluating scientific evidence.

Why it matters

A reported concentration does not eliminate questions about collection, contamination, storage, analysis, uncertainty or relation back to the time of driving.

Preservation priority

Independent expert review may be appropriate in contested scientific cases.

Attorney action

The defense should determine what underlying data exists and whether it supports the reported conclusion.

04

Medical, Prescription and Timeline Evidence

Medical conditions, injuries, fatigue, anxiety, balance limitations and prescribed medications may affect appearance, coordination, speech or test performance.

Why it matters

Receipts, phone records, location data and witness accounts may help establish a timeline.

Preservation priority

Accurate context can matter when the State relies on observations that have possible non-intoxication explanations.

Attorney action

Medical or prescription evidence should be evaluated carefully and disclosed strategically.

Identifying Every Responsible Party

What Must Be Examined in a Texas DWI Case?

A DWI defense evaluates both the legal authority for police action and the reliability of the evidence obtained.

Reasonable Suspicion for the Stop

The defense examines whether specific, articulable facts supported the traffic stop, detention or encounter.

Probable Cause for Arrest

The arrest must be supported by probable cause based on the totality of the circumstances, not merely a conclusion written after the fact.

Field Sobriety Test Conditions

Field sobriety tests should be reviewed for instructions, demonstration, administration, scoring and environmental or physical limitations.

Breath or Blood Collection

Breath or blood evidence should be examined for legal authorization, collection procedures, chain of custody, instrument or laboratory reliability and interpretation.

Laboratory and Instrument Reliability

Maintenance records, calibration documents, quality-control data and analyst qualifications may affect the weight or admissibility of scientific evidence.

Statements and Constitutional Rights

Statements may raise issues involving custodial interrogation, warnings, voluntariness, recording and the right to remain silent.

The Full Human and Financial Loss

Possible Consequences of a Texas DWI Case

A DWI case can affect liberty, driving privileges, finances, insurance, professional licensing and future opportunities. The possible outcome depends on the charge, evidence, history and circumstances.

Medical ExpensesEmergency care, surgery, rehabilitation, medication and future treatment.
Lost IncomeMissed work, reduced hours and diminished earning capacity.
Physical ImpairmentLimitations affecting mobility, work, hobbies and daily activities.
Pain and Mental AnguishPhysical suffering, emotional distress and loss of normal life.
DisfigurementScarring, burns, amputation or other permanent physical changes.
Property LossVehicle damage and other accident-related property expenses.

Intoxication Assault and Intoxication Manslaughter

Cases involving serious bodily injury or death may be charged as intoxication assault or intoxication manslaughter and require immediate accident reconstruction, causation and scientific investigation.

We request and review reports, body camera, dash camera, dispatch records, test records, laboratory material and available third-party video.

3

Scientific and Legal Analysis

We analyze the stop, detention, arrest, testing, constitutional issues, scientific reliability and potential motions.

4

Negotiation, Motions and Trial

We prepare for negotiation without sacrificing the ability to challenge evidence and try the case when appropriate.

Frequently Asked Questions

Texas DUI & DWI Defense FAQs

These answers provide general information and are not a substitute for legal advice about a particular arrest.

JP Law handles Texas DWI and related impaired-driving defense matters, including first-offense allegations, repeat allegations, felony DWI, drug-related DWI and cases involving accidents or enhanced charges.

The prosecution may rely on driving observations, officer testimony, field sobriety tests, statements, open containers, breath results, blood results, video, witnesses and crash evidence.

Important defense evidence may include body camera, dash camera, dispatch audio, booking video, business surveillance, medical records, receipts, phone or location data, test records and laboratory documents.

You have the right to remain silent. Basic identifying information and compliance with lawful instructions are different from volunteering explanations about drinking, medications, travel or test performance.

The Texas DPS ALR process is separate from the criminal case. In many refusal or breath-test-failure situations, a hearing must be requested within 15 days after service of the suspension notice; mailed blood-result notices may follow a different timeline.

Refusing a requested specimen can trigger license consequences, but the legal and evidentiary effect depends on the circumstances. Police may also seek a warrant for a blood draw.

Fees depend on the charge, county, history, complexity, expert needs and anticipated litigation. The written representation agreement controls the scope and fee.
