In most jobs, a DWI arrest is a personal problem. In trucking, it’s a career problem. Your CDL is your paycheck, and Texas can take it away over a single arrest. It doesn’t matter if you were off the clock and driving your own pickup on a Saturday night. The state will still come after the license that feeds your family.
Here’s a quick look at the consequences of CDL DWI in Texas:
- One-year CDL disqualification for a first offense
- Three-year disqualification if you were hauling hazardous materials
- Lifetime disqualification for a second offense
- A 0.04 BAC limit when driving a commercial vehicle
- CDL disqualification for refusing a breath or blood test
- Standard DWI penalties like fines, jail time, and license suspension
- Lost jobs and fewer carriers willing to hire you
That’s a lot to lose, but an arrest is not a conviction. Mark Thiessen has earned 160+ Not Guilty verdicts and thousands of dismissals by tearing apart the state’s evidence. He knows where these cases fall apart, and he knows how much your CDL is worth to you.

What happens to your CDL after a DWI in Texas?
A DWI can cost you your CDL for one year, three years, or the rest of your life. It depends on your record, your test results, and what you were hauling. These penalties come on top of the regular criminal punishment, and they apply whether you were driving a big rig or your own car.
One-year CDL disqualification for a first offense
If you’ve looked up the penalties for a DWI in Texas first offense, you probably saw fines, possible jail time, and a license suspension. Commercial drivers get hit with something extra: a one-year CDL disqualification. What catches most people off guard is that it doesn’t matter what you were driving. Your personal car, your buddy’s truck, or a rental on vacation all count the same. Texas treats any DWI conviction as a strike against your commercial license.
There’s no easy workaround, either. Texas won’t give you an occupational license to drive a commercial vehicle during that year. Texas law also doesn’t allow deferred adjudication for DWI if you held a CDL at the time of the offense. Federal rules block the state from “masking” a CDL holder’s conviction, so the plea deals that help regular drivers can be a trap for you. That’s why a DWI with a CDL case has to be fought from day one, not negotiated like a routine misdemeanor.
Three-year disqualification if you were hauling hazardous materials
If you were driving a vehicle placarded for hazardous materials at the time, that one year becomes three. The state’s reasoning is simple. A drunk driver in a sedan is dangerous, but a drunk driver hauling a tanker of fuel is a disaster waiting to happen. The trouble is that these cases often rest on the same shaky evidence as any other DWI. Shaky field sobriety tests and questionable breath results can still cost you three years.
Three years away from the road is long enough to end a hazmat career. Your endorsement and certifications may lapse in that time. You could be starting over with new paperwork and a fresh background check. Meanwhile, the carriers that valued your experience have already filled your seat.
Lifetime disqualification for a second offense
A second DWI conviction means a lifetime CDL disqualification. The same goes for a second refusal, or any combination of two major offenses from separate incidents. It doesn’t matter if the first one happened a decade ago. Of all the Texas CDL disqualifications, this is the one that ends careers for good.
“Lifetime” does have a narrow exception. Texas may let some drivers apply for reinstatement after 10 years, usually after completing an approved rehabilitation program. That’s at the state’s discretion, not yours. If you pick up another disqualifying offense after reinstatement, the ban becomes permanent with no second chances.
A 0.04 BAC limit when driving a commercial vehicle
Everyone knows the 0.08 limit. Once you’re behind the wheel of a commercial vehicle, the line drops to 0.04. For many people, that’s one or two drinks. A 0.04 doesn’t make you legally intoxicated under the Texas Penal Code, but it still triggers a CDL disqualification. That means you could beat the criminal case and still lose your commercial license.
It gets stricter from there. Any detectable alcohol at all, even below 0.04, can get you placed out of service for 24 hours. And the machines measuring these tiny amounts are far from perfect. Mouth alcohol, poor calibration, and sloppy testing procedures can all skew a result. When the legal line is this thin, a small machine error can decide your whole career.
CDL disqualification for refusing a breath or blood test
By driving in Texas, you’ve already agreed to implied consent laws. Refuse a breath or blood test and you’ll face the same one-year disqualification as a conviction (three years with hazmat). That happens even if you’re never convicted of DWI. On top of that, the state will suspend your regular license for 180 days on a first refusal. You only have 15 days to request an ALR hearing to fight it.
A refusal also counts as a strike toward that lifetime ban. Refuse once and get convicted later, and you’re done driving commercially. Worst of all, refusing rarely stops the test from happening. Officers can get a warrant for your blood in a matter of hours. So you can lose your CDL for refusing and still end up with a blood result the state uses against you.
Standard DWI penalties like fines, jail time, and license suspension
Every CDL consequence stacks on top of the regular criminal penalties. A first offense is a Class B misdemeanor with up to a $2,000 fine, 3 to 180 days in jail, and a license suspension of up to a year. Texas also tacks on a state fine of $3,000 at conviction, which jumps to $6,000 if your BAC was 0.15 or higher. That higher BAC also bumps the charge to what’s commonly called aggravated DWI, a Class A misdemeanor with up to a year in jail and a $4,000 fine.
A second offense carries 30 days to a year in jail, up to $4,000 in fines, and a longer license suspension. Add in ignition interlock devices, DWI education classes, and strict probation terms. The punishment for DWI in Texas is designed to drain your wallet and your calendar at the same time. For a driver who gets paid by the mile, every court date and probation meeting is money out of your pocket.
Lost jobs and fewer carriers willing to hire you
You can’t keep a CDL DWI quiet. Federal rules require you to notify your employer of a disqualification by the end of the next business day. You also have to report any conviction within 30 days. Carriers review your driving record at least once a year anyway. Many of their insurance companies won’t cover a driver with a recent DWI, so a pink slip often follows fast.
When your disqualification ends, the job market won’t be waiting for you. Plenty of carriers refuse to hire anyone with a DWI within the past several years. The ones that will may offer lower pay and worse routes. That’s why you need the best DWI lawyer in Houston before you plead to anything. The goal isn’t just a lighter sentence. It’s keeping that conviction off your record entirely.
Can you fight a CDL DWI in Texas?
Yes. An arrest is not a conviction, and the state still has to prove every piece of its case. A skilled DWI defense attorney can challenge the traffic stop, the field sobriety tests, the chemical test results, and the license suspension itself.
The strongest defense is one that attacks the state’s evidence at every step, including:
- Challenging the traffic stop: An officer needs reasonable suspicion to pull you over and specific signs of impairment to turn a routine inspection into a DWI investigation. If the stop or probable cause for the arrest doesn’t hold up, the evidence that came from it can be thrown out.
- Attacking field sobriety tests: After hours in the cab, fatigue, stiff knees, and red eyes can all look like “clues” to an officer eyeballing your performance on a busy highway shoulder. Bodycam footage and the officer’s training often tell a very different story.
- Questioning breath and blood results: At a 0.04 limit, mouth alcohol, poor calibration, or a blood sample drawn hours after the stop can make the difference. Thiessen Law Firm’s lead attorney is an ACS-CHAL Forensic Lawyer-Scientist who knows how to challenge breathalyzer results and the state’s experts.
- Winning the ALR hearing: You have just 15 days to request an ALR hearing, or your suspension starts automatically. Winning it can protect your license, and it gives your attorney a chance to question the arresting officer under oath.
For commercial drivers, fighting back isn’t optional. A plea deal might look like the easy way out, but with no deferred adjudication available and no masking allowed, a plea can end your career just as fast as a guilty verdict.

Consequences of a CDL DWI — FAQs
Do you lose your CDL if you get a DWI?
Yes. A DWI conviction in any vehicle triggers at least a one-year CDL disqualification in Texas. You can also lose your CDL before you’re ever convicted if you refuse a breath or blood test or test over the legal limit.
Can I get my CDL back after a DWI?
In most cases, yes. After a one-year or three-year disqualification ends, you can reinstate your CDL by meeting DPS requirements and paying the reinstatement fees. A lifetime disqualification is much harder to undo, though some drivers may be able to apply for reinstatement after 10 years, and only once.

Can you get a CDL with 3 DWIs in Texas?
Realistically, no. Two DWI convictions while holding a CDL already trigger a lifetime disqualification, and a third DWI in Texas is a third-degree felony. Even if you could get the license, very few carriers or insurers will take on a driver with three DWIs on record.
Does a DWI in your personal vehicle count against your CDL?
Yes. Texas applies the same CDL disqualifications to a DWI in your personal car as it does to one in a commercial vehicle. Being off the clock won’t protect your commercial license.
Does an out-of-state DWI affect my Texas CDL?
Yes. States share CDL violations through a national database, so a DWI conviction in Louisiana or Oklahoma will be reported back to Texas. Texas will then disqualify your CDL just as if the offense happened here.
