Short answer: If you hold a Texas commercial driver's license (CDL), a first DWI conviction disqualifies you from driving a commercial vehicle for one year, even if you were arrested in your personal pickup on a Saturday night. Refusing a breath or blood test, or testing at 0.08 or higher in your own car, can trigger the same one-year disqualification. A second offense means a lifetime disqualification. CDL holders also can't get deferred adjudication for DWI, can't get an occupational license to drive a commercial vehicle, and can't have the disqualification probated.
For truck drivers, bus drivers, delivery drivers, and equipment operators across Dallas-Fort Worth, a DWI arrest isn't just a criminal case. It's a threat to your livelihood. Whether the stop happened on I-35W near AllianceTexas, on I-20 in Grand Prairie, or on a farm-to-market road in Parker County, the CDL rules apply the same way.
At Howard Lotspeich Alexander & Williams, PLLC (HLAW), our Fort Worth DWI attorneys defend commercial drivers in Tarrant, Dallas, Denton, Collin, Johnson, and Parker counties. This guide explains what's at stake, the deadlines that matter, and the defense options that protect your CDL.
Key Takeaways
- One year off the road for a first DWI conviction, in any vehicle. Texas disqualifies a CDL holder for one year on a first conviction of driving under the influence, and the rule applies while "operating any type of motor vehicle, including a commercial motor vehicle" (Tex. Transp. Code §522.081(b)).
- Refusal or a 0.08+ test in your own car counts too. A refusal, or a test showing 0.08 or more while driving a non-commercial vehicle, is a separate one-year trigger (§522.081(b)(3)–(4)).
- 0.04 is the limit in a commercial vehicle. A test of 0.04 or more while operating a CMV means disqualification, and any detectable alcohol puts you out of service for 24 hours (§§522.081, 522.101).
- Hazmat means three years; a second offense means life. (§522.081(c)–(d); 49 CFR 383.51).
- No deferred adjudication for CDL holders charged with DWI (Tex. Code Crim. Proc. art. 42A.102(b)(1)(B)).
- No occupational license for a CMV, and no probated disqualification (§§522.085–.086).
- You have 15 days to request an ALR hearing after receiving notice of suspension (Tex. Transp. Code §524.031).
Does a DWI in My Personal Car Affect My CDL in Texas?
Yes. This is the most common misunderstanding we hear from commercial drivers. Section 522.081(b) of the Transportation Code says the one-year disqualification applies to a violation "committed while operating any type of motor vehicle, including a commercial motor vehicle" (Tex. Transp. Code §522.081). Federal rules match: the disqualification table in 49 CFR 383.51 lists a one-year disqualification for a first DWI conviction whether you were driving a CMV or a non-CMV.
So a DWI in your own car can take you out of your truck for a year, even though your regular Class C driving privileges might be eligible for an occupational license.
What Are the CDL Disqualification Periods for DWI in Texas?
| Situation | CDL disqualification | Source |
|---|---|---|
| First DWI conviction (any vehicle) | 1 year | §522.081(b)(2) |
| Refusing a breath or blood test (any vehicle) | 1 year | §522.081(b)(3) |
| Test of 0.08+ in a personal vehicle | 1 year | §522.081(b)(4)(B) |
| Test of 0.04+ (or drugs present) in a CMV | 1 year | §522.081(b)(4)(A) |
| Any of the above while hauling placarded hazmat | 3 years | §522.081(c) |
| Two or more qualifying offenses or refusals from separate incidents | Life | §522.081(d) |
| Any detectable alcohol while driving a CMV, or refusing a CMV test | 24-hour out-of-service order | §522.101 |
The lifetime rule is stricter than many drivers realize. Under §522.081(d)(3), any combination of two of the following from separate incidents triggers it: a DWI conviction, a test refusal, or a qualifying test result. For example, a refusal five years ago plus a DWI conviction today can mean lifetime disqualification. Federal rules allow a state to reinstate a driver disqualified for life after 10 years if the driver completes an approved rehabilitation program, but a second disqualifying conviction after reinstatement is permanent (49 CFR 383.51(a)(6)).
Why Can't a CDL Holder Get Deferred Adjudication for DWI?
Since 2019, Texas judges have been able to grant deferred adjudication in many first-time DWI cases. Our DWI deferred adjudication guide explains how it works. But the statute carves out an exception: deferred adjudication isn't available for a DWI charge if, at the time of the offense, "the defendant held a commercial driver's license or a commercial learner's permit" (Tex. Code Crim. Proc. art. 42A.102(b)(1)(B)(i)). The same bar applies if the alcohol concentration was 0.15 or more.
This tracks a federal rule. States "must not mask, defer imposition of judgment, or allow an individual to enter into a diversion program" that would keep a CDL holder's traffic-law conviction, in any type of vehicle, off the national CDL driver record (49 CFR 384.226). In practice, the options that help non-commercial drivers often aren't available to you, which makes the strength of the defense even more important.
Can I Get an Occupational License to Keep Driving My Truck?
No. Texas law says a person disqualified from operating a commercial motor vehicle "may not be granted an essential need or occupational driver's license that would authorize operation of a commercial motor vehicle" (§522.086). The disqualification also "may not be probated" (§522.085).
You may still qualify for an occupational license for your personal (non-commercial) driving during a regular license suspension. Our article on Texas DWI license suspensions and occupational licenses covers that process.
How Does the ALR Hearing Work for Commercial Drivers?
After a DWI arrest with a refusal or a failed test, DPS will seek to suspend your license through the Administrative License Revocation (ALR) process. For adults, the regular suspension is 90 days with no alcohol- or drug-related enforcement contact in the prior 10 years, or one year with such a contact (§524.022). You must request a hearing within 15 days of receiving notice (§524.031). See our step-by-step guide to the ALR hearing and its 15-day deadline.
For CDL holders, the ALR stakes are higher. A test result of 0.08 or more in your personal vehicle, or a refusal, is itself a basis for CDL disqualification under §522.081(b)(3)–(4), separate from any criminal conviction. When a driver stopped in a commercial vehicle refuses or tests 0.04 or more, the officer files a sworn report, and DPS disqualifies the driver beginning on the 45th day after receiving it "unless a hearing is granted" (§§522.104–.105).
The ALR hearing is also a valuable chance to question the arresting officer under oath early in the case. That testimony can expose problems with the stop, the field sobriety tests, or the breath or blood testing.
What Do I Have to Tell My Employer?
Federal regulations require commercial drivers to report certain events to their employers:
- Convictions. A CDL holder convicted of a traffic violation (other than parking), in any type of vehicle, must notify the employer "within 30 days of conviction" (49 CFR 383.31).
- Suspensions and disqualifications. If your license is suspended, revoked, canceled, or you're disqualified, you must tell your employer "before the end of the business day following the day the person received notice of the action" (49 CFR 383.33).
Many companies also have their own policies that require reporting an arrest sooner. Talk with a lawyer before you make any written statement to your employer about the facts of the arrest.
Will a DWI show up in the FMCSA Clearinghouse?
It depends on what you were driving. According to FMCSA, a DUI in a personal car "is not considered 'actual knowledge'" and "must not be reported to the Clearinghouse" (FMCSA Clearinghouse Q&A). But if you receive a citation for DUI while operating a CMV, your employer must report it as an actual-knowledge violation. That report remains for five years or until you finish the return-to-duty process, whichever is later, even if you're never convicted. You can, however, submit proof of a dismissal or acquittal (FMCSA Clearinghouse FAQ). Under FMCSA's enforcement policy, a plea to a lesser charge such as reckless driving doesn't count as a "non-conviction" (FMCSA).
What Defense Strategies Protect a CDL?
Because deferred adjudication and occupational CMV licenses are off the table, the best outcomes for commercial drivers usually come from attacking the case itself:
- The stop. Was there reasonable suspicion for the traffic stop? Weaving within a lane, a single lane touch, or a "late-night" hunch may not be enough.
- Field sobriety tests. Were the standardized tests administered and scored correctly? Truck drivers often have long-shift fatigue, back injuries, or footwear issues that affect balance tests.
- Breath and blood testing. Was the breath instrument properly maintained? Was the blood draw taken under a valid warrant, and was the chain of custody intact? See our no-refusal DWI article.
- Impairment under 0.08. Texas can charge DWI based on loss of normal use even below 0.08. Our article on DWI arrests under 0.08 explains how those cases are defended.
- Dismissal or acquittal. A dismissal or a not-guilty verdict avoids the conviction-based disqualification under §522.081(b)(2). (A refusal or test-based disqualification is a separate issue, so the ALR fight still matters.)
- Charge reductions, with caution. A plea to a non-alcohol offense avoids a DWI conviction, but some offenses still have CDL consequences. Reckless driving, for example, is a "serious traffic violation," and two within three years mean a 60-day disqualification (§§522.003(25), 522.081(a)).
What Should a CDL Driver Do After a DWI Arrest in DFW?
- Calendar the 15-day ALR deadline today.
- Don't drive a commercial vehicle while subject to any out-of-service order or disqualification. Doing so is a separate offense under §522.071.
- Write down everything you remember about the stop, the tests, and what the officer said, and share it only with your lawyer.
- Gather your records: your medical card, logbook or ELD data, and any dash-cam or in-cab camera footage.
- Know your employer reporting deadlines under 49 CFR 383.31 and 383.33.
- Hire a DWI lawyer who knows the CDL rules. A plea that might be fine for a regular driver can end a commercial driving career. See our overview of DWI costs in Texas for the broader financial picture.
Frequently Asked Questions
Will I lose my CDL for a first DWI in my personal car in Texas?
If you're convicted, yes. A first DWI conviction disqualifies a CDL holder from driving a commercial vehicle for one year, regardless of the vehicle you were driving (§522.081(b)). A refusal or a 0.08+ result can also trigger the one-year disqualification.
What is the legal limit for a commercial driver in Texas?
0.04 while operating a commercial motor vehicle (§522.081(b)(4)(A)). Any detectable amount of alcohol while driving a CMV results in a 24-hour out-of-service order (§522.101). In your personal vehicle, the per se limit is 0.08.
Can a CDL holder get deferred adjudication or pretrial diversion for DWI?
Texas law bars deferred adjudication for a DWI if the defendant held a CDL or commercial learner's permit at the time of the offense (art. 42A.102), and federal rules prohibit states from using deferral or diversion to keep a CDL holder's traffic-law conviction off the record (49 CFR 384.226).
Can I get an occupational license to drive my truck during the disqualification?
No. An occupational license can't authorize commercial driving for a disqualified driver, and the disqualification can't be probated (§§522.085–.086).
Is a second DWI really a lifetime CDL ban?
Two qualifying offenses from separate incidents, including combinations of convictions, refusals, and failed tests, result in lifetime disqualification (§522.081(d)). Federal rules allow a state to reinstate after 10 years with an approved rehabilitation program (49 CFR 383.51).
Does my employer find out about a DWI arrest?
Federal rules require you to report a conviction within 30 days and a suspension or disqualification by the end of the next business day (49 CFR 383.31; 49 CFR 383.33). A DUI citation in a CMV is reported to the Clearinghouse by your employer.
