DWI Defense Services In Dallas

Driving while intoxicated is not one charge. It is a family of offenses graded by history, circumstances, and consequences, each with its own evidence, deadlines, and defense strategy. Our attorneys handle every DWI-related matter that comes through Dallas County courts, from a first arrest to a felony indictment to the license fight that runs alongside the criminal case.

First-Time DWI Defense

A first offense DWI is usually filed as a Class B misdemeanor, elevated to Class A when a test shows an alcohol concentration of 0.15 or higher. The case still threatens your license, your insurance rates, and a permanent record, because a DWI conviction cannot be expunged in Texas. Our attorneys examine the stop, the field tests, and the chemical evidence before advising you on anything. Many first-time clients have more options than they realize, including resolutions that preserve future record-clearing eligibility.

Repeat Or Multiple DWI Offenses

A second DWI is a Class A misdemeanor carrying mandatory jail exposure and longer license suspensions, and prosecutors treat a repeat DWI as proof of a pattern. Defending these cases means more than negotiating. It means auditing whether earlier convictions are valid enhancements and whether the new evidence holds together on its own. We challenge the current arrest on its merits while scrutinizing the paperwork behind every prior conviction the State intends to use against you.

Felony DWI Cases

A third DWI arrest is charged as a third-degree felony in Texas, punishable by two to ten years in prison and a fine of up to $10,000. A felony conviction also strips civil rights and closes professional doors for life. Cases this serious call for a felony DWI lawyer who tries cases, not one who only settles them. We prepare every felony DWI for trial from the first meeting, which changes how prosecutors evaluate the file long before a jury is ever selected.

DWI With Child Passenger

Driving while intoxicated with a passenger younger than 15 is a state jail felony even on a first arrest, and it frequently draws parallel attention from child welfare authorities. The stakes reach beyond the courtroom into custody and family life. Our team moves on both fronts at once, contesting the intoxication evidence itself while working toward a resolution that protects your record and your role as a parent.

Breath Test Defense

Texas breath testing relies on Intoxilyzer instruments that estimate blood alcohol from a breath sample, and that estimate depends on proper calibration, a certified operator, a mandatory observation period, and physiological assumptions that do not fit everyone. We obtain maintenance records, operator credentials, and reference sample data, then look for the gaps. A breath number is only as reliable as the machine and the procedure behind it, and both can be challenged.

Blood Test Defense

Blood evidence feels definitive to jurors, which is exactly why it deserves the hardest look. A valid result requires a lawful warrant or consent, a proper draw, an unbroken chain of custody, correct storage, and accurate gas chromatography analysis at the laboratory. Errors occur at every stage. Our attorneys review lab records, analyst qualifications, and warrant affidavits line by line, and we retain independent experts when the science warrants a second opinion.

Administrative License Revocation (ALR) Hearings

A DWI arrest starts a separate civil case against your driver's license. You have 15 days to request an Administrative License Revocation hearing; miss that deadline and the suspension begins automatically on day 40. As ALR hearing lawyers, we request these proceedings routinely, and not only to fight the suspension. An ALR hearing lets us question the arresting officer under oath months before trial, locking in testimony that often becomes the backbone of the criminal defense.

Occupational License Assistance

If your license is suspended, Texas law allows a court-ordered occupational driver's license so you can drive to work, school, and essential household duties. Obtaining one requires a petition, proof of financial responsibility, and sometimes an ignition interlock device, with requirements that vary by court and driving history. We handle the filings and the appearances so that a suspension does not cost you your job while the underlying case is still being fought.

Hardship License Assistance

Some drivers do not fit neatly into the standard occupational license framework, including younger drivers and people carrying layered or overlapping suspensions. Restricted driving relief may still be available. Eligibility depends on the reason for the suspension, prior orders, and any interlock requirements. We evaluate every lawful path back to driving, explain what each option demands, and pursue the one that restores your mobility fastest without jeopardizing the criminal case.

Intoxication Assault Defense

When an allegedly intoxicated driver causes serious bodily injury to another person, Texas charges intoxication assault, a third-degree felony. These cases turn on two disputed questions: whether the driver was actually intoxicated and whether intoxication, rather than road conditions or another driver's choices, caused the injury. Accident reconstruction, medical records, and toxicology all come into play. We build the defense around the causation evidence the State would prefer to gloss over.

Intoxication Manslaughter Defense

A fatality allegation is the most serious DWI-related charge in Texas, a second-degree felony carrying up to 20 years in prison. Grief and public pressure push these cases toward fast conclusions, which makes independent investigation essential. Our attorneys retain reconstruction and toxicology experts early, work to preserve physical evidence before it disappears, and hold the State to its full burden of proving both intoxication and causation beyond a reasonable doubt.

Underage DWI Defense

Texas enforces a zero-tolerance rule for drivers under 21. Any detectable amount of alcohol supports a charge, and a young driver at a 0.08 concentration faces the same DWI statute as an adult. A conviction can shadow college applications, professional licensing, and an early career. We defend these cases with the long view in mind, pressing for outcomes that keep young records clean and preserve expunction eligibility wherever the law allows.

DWI Probation Violations

An alleged probation violation, from a missed class to a flagged interlock reading, can bring a motion to revoke and an arrest warrant. The State's burden at a revocation hearing is lower than at trial, so preparation matters even more. We respond fast, address bond, and present the full context behind the allegation, working to keep clients on supervision or restructure its terms rather than watch probation convert into jail time.

Expunction Guidance

Texas allows expunction when a DWI charge ends in acquittal, dismissal, or no-bill, erasing the arrest from public records. A conviction cannot be expunged, though certain first-time DWI convictions qualify for an order of nondisclosure that seals the record from most private employers. The defense strategy you choose today determines which doors stay open tomorrow, so we map record-clearing eligibility at the start of every case, not after it ends.

A DWI Defense Built On Evidence, Procedure & Preparation

Who We Are & Who We Represent

Dallas DWI Lawyers is a Texas criminal defense team with a deliberately narrow focus: defending people accused of driving while intoxicated and the offenses that surround it. The practice is led by Gary L. Medlin, licensed in Texas since 1983 and Board Certified in Criminal Law by the Texas Board of Legal Specialization since 1989. Before devoting his career to the defense, he spent nearly a decade prosecuting cases as an assistant district attorney. A second attorney on our team served six years in a district attorney’s office as well. Combined, our lawyers bring more than 70 years of criminal courtroom experience to every file.

That background shapes everything downstream. Former prosecutors read an offense report differently. They can see which facts the State will lean on, which witnesses will hold up under oath, and where a case is thinner than its paperwork suggests. A Dallas DWI attorney who has built prosecutions from the inside starts dismantling them with a map instead of a flashlight.

Peer Reviews

Gary is a gentleman & a scholar

Gary is a gentleman and a scholar who helped me out recently when I was in a bind and needed some help on a case that had some Texas implications. He was Johnny on the spot, interrupted his weekend, and followed through perfectly. I am glad not only to call him a colleague, but also my friend.

the “go-to” lawyer in Tarrant County

I endorse this lawyer. Gary Medlin is a “stand-up” criminal lawyer and the “go-to” lawyer in Tarrant County for ALR hearings. I have regularly hired him as local counsel in Fort Worth and I will continue to do so.

DWI Defense In Dallas

Dallas is a driving city, and most DWI arrests here begin with something unremarkable. A late dinner in Uptown. A show in Deep Ellum. A drive back to Lake Highlands after a delayed flight into Love Field. Then the lights come on somewhere along US-75 or I-35E, and an ordinary night becomes a criminal case in Dallas County.

Local defense starts with local geography. Enforcement concentrates where nightlife and highways meet: the corridors feeding out of Deep Ellum onto I-30, the Dallas North Tollway ramps that carry traffic home from Uptown toward Preston Hollow and North Dallas, the Cedar Springs strip in Oak Lawn, and the restaurant blocks of Bishop Arts in north Oak Cliff. Patterns shift with the calendar, too. The weeks around the State Fair bring saturated patrols near Fair Park, and holiday weekends often mean no-refusal initiatives, with judges on standby to sign blood warrants around the clock. An attorney who defends cases in this city recognizes those patterns in an offense report immediately.

Where Your Case Will Be Heard

Nearly every DWI arrest in the county, regardless of which agency made it, is prosecuted by the Dallas County District Attorney’s Office and heard at the Frank Crowley Courts Building just west of downtown Dallas. Misdemeanor cases go to the county criminal courts. Felony DWIs, intoxication assault, and intoxication manslaughter cases are assigned to the felony district courts. Each court manages its docket in its own way, from how settings are scheduled to how discovery disputes get resolved to what a judge expects before hearing a motion. Attorneys who appear in these courts week after week learn those rhythms, and clients feel the difference in shorter timelines and fewer surprises.

The people across the aisle matter as well. Prosecutorial filing practices, reduction policies, and diversion criteria in Dallas County evolve with each administration, and they differ meaningfully from neighboring counties. A defense calibrated to how Dallas actually charges and resolves cases today will outperform one built from a statewide template every time.

The Agencies Behind Dallas Arrests

Arrests come from more directions than most people expect. Dallas Police Department units work the entertainment districts. Texas DPS troopers patrol I-35E, I-30, and the tollway system. Dallas County sheriff’s deputies and dozens of suburban departments across the northern half of the county make arrests that all funnel into the same courthouse. Travelers face their own exposure near Love Field and DFW Airport, where an arrest can complicate employment, security clearances, and immigration status in ways a standard case does not. Every agency has its own report formats, video systems, and testing practices, and familiarity with those habits helps a defense team find the inconsistencies faster.

Fifteen Days, Then Forty

The Administrative License Revocation deadline applies with full force in Dallas. Request a hearing within 15 days of your arrest and the suspension is put on hold until an administrative law judge rules; let the deadline pass and your license is suspended automatically on day 40. These hearings are conducted through the State Office of Administrative Hearings, with the Department of Public Safety on the other side. Handled well, an ALR hearing does double duty. It contests the suspension, and it puts the arresting officer under oath early, creating a sworn record the defense can use for the remainder of the criminal case.

Local Knowledge Is Not A Slogan Here

A lawyer defending a Dallas DWI from a distance misses what a Dallas lawyer reads at a glance: which stretch of I-30 the stop occurred on and what the video from that corridor typically shows, which facility analyzed the blood, which court will receive the filing, and how quickly that court moves. From White Rock Lake to Bishop Arts, from Preston Hollow to Deep Ellum, people from every corner of this city end up facing the same charge in the same building. The ones who fare best share one habit: they put a defense in motion early.

Board Certification in Criminal Law: What It Means for Your DWI Case

Texas created the first attorney board certification program in the country in 1974 through the Texas Board of Legal Specialization, and its standards remain demanding. To become Board Certified in Criminal Law, an attorney must practice for years with substantial, documented involvement in criminal matters, complete specialized continuing legal education, pass confidential evaluations by judges and fellow lawyers who have seen the attorney’s work firsthand, and pass a rigorous daylong examination in the specialty. The credential is not permanent. It must be renewed every five years through continued education and continued substantial work in the field.

Most Texas lawyers never pursue it. Roughly one in ten licensed attorneys in the state holds board certification in any specialty, and the number certified specifically in criminal law is smaller still. The certification exists precisely because the words “experienced criminal lawyer” appear on thousands of websites, and clients have no independent way to verify them. Board certification is the State Bar’s answer: a claim of specialized competence that has actually been examined, tested, and confirmed.

For a person facing a DWI charge, the certification matters in practical terms. DWI is a technical corner of criminal law where cases are won and lost on suppression motions, instrument records, laboratory science, and judgment calls about when to negotiate and when to try the case. An attorney whose depth in this field has been verified by the state’s certifying body, and re-verified every five years for more than three decades, brings that depth to each of those decisions.

Honesty requires saying the rest plainly. Certification does not decide cases, and no credential guarantees an outcome. Preparation, evidence, and law decide cases. What board certification offers is confidence that the person making the strategic decisions in your case has met a standard most lawyers never attempt, judged by the peers and judges best positioned to know.

Why Choose Our Team

Choosing a lawyer after a DWI arrest usually happens under pressure, with little time and less clarity. These are the facts about our team that matter most to that decision. Each one is verifiable, and none of it is puffery.

Board Certified Leadership Since 1989

Our lead attorney has held Board Certification in Criminal Law from the Texas Board of Legal Specialization for more than three decades, a credential earned through examination and peer review and renewed continuously since 1989.

Prosecutors Turned Defenders

Two of our attorneys began their careers in district attorneys’ offices, one serving nearly a decade and another serving six years. They have written the charging decisions, prepared the officers, and tried the cases from the State’s table. That perspective now works for the defense.

More Than 70 Years Of Combined Courtroom Experience

Our attorneys have spent their careers in Texas criminal courts, handling thousands of matters across every level of offense. That accumulated judgment shows up in the small decisions that shape big outcomes: which motion to file, which question to ask, which offer to refuse.

Criminal Defense Is All We Do

The firm practices no other kind of law. No family cases, no civil litigation, no side practices. A team focused entirely on criminal defense stays current on the statutes, the science, and the case law that decide DWI cases, because nothing else competes for its attention.

Every Case Prepared As If It Will Be Tried

Prosecutors evaluate a case partly by the lawyer standing across from them. Files built for trial from the first day produce better negotiated outcomes and stronger verdicts when negotiation is not enough. Preparation is the strategy; everything else follows from it.

A Full Team On Every File

Clients hire the firm, not a single overloaded calendar. Attorneys collaborate on strategy, paralegals and legal assistants keep evidence and deadlines organized, and someone who actually works on your case can answer your questions when you call.

National Involvement In DWI Defense

Our lead attorney is a founding member of the DUI Defense Lawyers Association and a member of the National College for DUI Defense, with published work and continuing legal education presentations on DWI defense topics. Teaching this material requires mastering it, and that mastery flows directly into client cases.

Reachable When It Matters

Arrests do not happen during business hours. Our phones are answered live 24 hours a day, seven days a week, and our team serves clients in English, Spanish, Russian, and Ukrainian.

The Sooner We See Your Case, The More We Can Do With It

Evidence is freshest, deadlines are furthest away, and options are widest right now. Bring us the facts and get a straight assessment of where your case stands, what it will take to fight it, and what deadlines are already moving. Schedule your Free Case Evaluation today.
