A DWI arrest doesn’t make you a criminal. It makes you a person who needs a plan.
Right now you’re probably replaying the stop in your head: the lights, the questions, the tests, the cuffs. Take a breath. What happens next matters a lot more than what happened last night, and what happens next is our job, not yours.

Why People Facing a DWI Hire Jay Cohen
Most DWI lawyers cross-examine the State’s science from the outside. Jay learned the science itself:
- ACS-CHAL Forensic Lawyer-Scientist, a designation from the Chemistry & the Law Division of the American Chemical Society held by only a small group of attorneys nationwide
- Certified practitioner and instructor in Standardized Field Sobriety Testing (SFST). Jay doesn’t just know the tests the officer gave you; he’s qualified to teach them
- Certified Drug Recognition Expert (DRE)
- Trained in forensic chromatography, the actual lab method behind Texas blood-alcohol results
- Founding member, DUI Defense Lawyers Association; member, National College for DUI Defense; appointed to the Texas Indigent Defense Commission by Gov. Abbott in 2024
Almost every Houston DWI case is built on the stop and on the tests that came after it, field and chemical. The State assumes you’ll take their numbers at face value. We don’t. We pull the maintenance records and the raw lab data. We watch the video. Then we check their work, and often it doesn’t hold up.
The Science Is Our Home Field
The breath machine
The Intoxilyzer doesn’t measure your blood alcohol, it estimates it, using assumptions about your body that may not be true for you. Radio interference, mouth alcohol, acid reflux, even a low-carb diet can push a reading up. See how we challenge DWI breath tests.
The blood draw
Texas labs analyze blood with headspace gas chromatography. Jay is trained in that exact discipline, so instead of accepting the lab’s one-page report, we read the underlying chromatograms and audit your sample from the draw to the run. Fermentation in the vial and expired tubes show up more often than the State would like you to know. So does sloppy chain of custody.
The roadside tests
The three standardized field sobriety tests are graded on strict NHTSA rules, and officers break those rules constantly. Jay is a certified SFST instructor. When the officer’s technique is wrong, the “clues” are worthless, and we show the jury exactly why. See how we challenge field sobriety tests.
First Things First: The 15-Day Clock on Your License
Your criminal case and your driver’s license are two separate fights. If you refused testing or blew over the limit, DPS moves to suspend your license automatically, and you have only 15 days from the date you receive your notice of suspension to request the hearing that puts the suspension on hold and lets us fight it. Miss the deadline and the suspension just happens.
Requesting that hearing also gets us an early shot at cross-examining the arresting officer under oath, months before trial. Don’t sit on it. Read what happens at an ALR hearing so you know what’s coming.
What You’re Facing: Texas DWI Penalties
Your exposure under Texas Penal Code Chapter 49:
- First DWI. Class B misdemeanor: up to 180 days in jail, fines and state fees, license suspension. Houston first-offense DWI lawyer
- First DWI with BAC 0.15+. Class A misdemeanor: up to a year in jail and steeper fines.
- First DWI in a school crossing zone. State jail felony under Penal Code § 49.04(e), a change the Legislature made effective September 1, 2025. This one catches people who have no idea the zone applies where they were driving.
- Second DWI. Class A misdemeanor with mandatory minimum jail time. Houston second-offense DWI lawyer
- Third DWI or more. Third-degree felony: 2 to 10 years. Houston felony DWI lawyer
- DWI with a child passenger. State jail felony. DWI with a child passenger
- Intoxication assault or intoxication manslaughter. Felonies with prison exposure measured in years, not months. Intoxication assault · Intoxication manslaughter
Beyond the courtroom: the state traffic fine of $3,000 or more, insurance, background checks, professional licenses, immigration consequences. That’s exactly why the goal is to keep a conviction off your record in the first place. That is what Keeping Innocent People Innocent® means in practice.
How We Fight Houston DWI Cases
Every case is different, but the playbook starts the same way. We make the State prove every link in its chain:
- Was the stop legal? No reasonable suspicion, no case. Harris County officers make illegal stops more often than you’d think, and the video usually tells the truth.
- Was the arrest supported by probable cause? “Odor of alcohol and red eyes” is not intoxication.
- Do the field tests survive scrutiny? Instructor-level review of every clue the officer claims.
- Does the chemical test survive scrutiny? Machine records, lab audits, raw chromatography data.
- Should you take a plea at all? You’ll get a straight answer from us. If a deal is truly your best outcome, we’ll negotiate it hard, but we prepare every case like it’s going to trial, because that’s what gets the good offers.

- Calendar day 15. The ALR request deadline is unforgiving.
- Stop talking about the case. Not to friends, not on social media, and definitely not to investigators.

Houston DWI FAQs
How much does a DWI lawyer cost in Houston?
Less than a conviction. Fees depend on whether your case is a first-offense misdemeanor or a felony headed to trial, and we’ll quote you a flat picture up front at the free consult, no surprises. When you weigh it against the $3,000-plus state traffic fine, insurance hikes and a permanent record, fighting the case is usually the cheaper path.
Can I beat a DWI if I failed the breath or blood test?
Yes. People do it every week in Harris County. A number is only as good as the machine, the operator, and the lab that produced it. We’ve seen breath scores undermined by medical conditions and maintenance failures, and blood results undone by how the sample was stored and analyzed. Our forensic approach goes looking for exactly those problems.
Should I have refused the tests?
That decision’s already made, so don’t beat yourself up either way. A refusal gives the State less evidence but triggers a longer license suspension; a failed test gives us science to attack. Either way, there’s a defense path.
Will I lose my license?
It can happen automatically if you don’t act. If you refused or tested over the limit, you must request an ALR hearing within 15 days of receiving your notice of suspension. Even if a suspension eventually lands, we can usually get you an occupational license so you can keep driving to work.
Is a first DWI worth fighting?
Almost always. A first conviction follows you for life in Texas, and there’s no automatic expunction. Beat the case or resolve it the right way, and you may be able to clear or seal your record entirely.

The Texas statutes behind these charges
Everything the State has to prove against you is written down in Chapter 49 of the Texas Penal Code, and it is worth reading the actual language instead of somebody’s summary of it. The core offense is Section 49.04, driving while intoxicated. Having a child under fifteen in the car moves it to Section 49.045. Prior convictions are what turn a misdemeanor into a felony, and Section 49.09 is where those rules live. If somebody was seriously injured the charge becomes intoxication assault under Section 49.07, and if somebody died it becomes intoxication manslaughter under Section 49.08. Every one of them, with the punishment ranges and the enhancements side by side, is on our Texas DWI laws and penalties page. Texas also criminalizes operating things other than a car while intoxicated: a boat under Section 49.06, an aircraft under Section 49.05, and, yes, an amusement ride under Section 49.065.
Still figuring out what you are up against
Most people land here a few days after an arrest with no real idea what happens next. If that is you, start with what happens on a first DWI in Texas and how long probation runs on a first offense. Then read how a Texas DWI case moves from arrest to verdict. If you refused testing or tested over the limit, the first deadline is the 15-day window to request a hearing and fight the license suspension, and it runs out before most people have even talked to a lawyer.
Other Houston DWI situations we handle
A DWI charge doesn’t carry the same weight for everyone. Often the real exposure has less to do with the arrest itself than with what you do for a living or where you live, and sometimes with what you own. If you run your own company, the risk reaches your contracts and your commercial insurance as much as your license, and your professional reputation takes a hit too. We cover that for a Houston small business owner facing a DWI. Gun owners have a separate problem, because a pending charge and a final conviction affect your right to carry in different ways, and that’s the subject of our page on DWI and your firearm rights. Students can face campus discipline and lose scholarships on top of the criminal case, which we address for a Houston college student arrested for DWI. If you were arrested here but licensed somewhere else, two states now have a say in your driving privileges, and our page on an out-of-state DWI arrest in Houston explains how that works. Pilots answer to federal reporting rules that run on their own clock, covered in flying while intoxicated. Riders should read our page on a Houston motorcycle DWI, because the stop and the balance-based field tests play out differently on a bike. So do the injuries. Two other issues come up constantly: the SCRAM alcohol monitoring bracelet, which shows up in bond and probation orders, and the Texas open container rule, which can raise the jail minimum on a DWI. And if all you want is a map of the months ahead, start with the Texas DWI process from arrest to resolution.
