Commercial Vehicle DWI Lawyer In Conroe, TX
A commercial driver's license is a livelihood, and Texas can disqualify it for a year after a single DWI, whether the arrest happened in a tractor trailer or a personal pickup on a Saturday night. This page covers the 0.04 rule, the disqualification periods, the plea options a CDL holder does not have and the deadlines that start at arrest.
How Does A DWI Affect A CDL In Texas?
A commercial driver faces the ordinary DWI charge under Penal Code § 49.04 and a separate disqualification under Transportation Code § 522.081. The CDL can be disqualified for one year after a DWI conviction in any vehicle, a refusal, or a test at 0.04 in a commercial vehicle or 0.08 in a personal one. The period is three years with hazardous materials and lifetime after a second qualifying event.

Understanding Texas Law
How Does A DWI Affect A Commercial Driver's License In Texas?
A commercial driver charged with DWI is prosecuted under the same statute as everyone else, Texas Penal Code § 49.04, with the same penalty range. The difference is what happens to the commercial license. Transportation Code chapter 522 governs commercial licenses, and it adds a disqualification from driving commercial vehicles on top of any ordinary suspension.
Texas builds those rules on the federal standards in 49 C.F.R. part 383, which is why the disqualification periods look alike from state to state. A disqualification is not the same as a suspension. It bars commercial driving even while the ordinary license is valid.
Under § 522.081, a CDL holder can be disqualified for:
- A 0.04 or higher alcohol concentration while operating a commercial motor vehicle
- A controlled substance or drug in the body while operating a commercial motor vehicle
- A 0.08 or higher alcohol concentration in a non-commercial vehicle
- Refusing a requested breath or blood test
- A DWI conviction, whatever was being driven
How long the disqualification lasts under § 522.081:
- One year on a first qualifying offense
- Three years if the vehicle was placarded for hazardous materials
- Lifetime on a second qualifying offense
The 0.04 number belongs to the commercial license rules, not the Penal Code. The criminal case still turns on 0.08 or loss of normal use of faculties.
A driver who holds a CDL and is arrested on the way home from a cookout faces the same disqualification as one arrested in a loaded rig. The personal side of that arrest is covered on the first DWI page.
Penalties And Consequences
What Are The Penalties For A CDL Holder's DWI In Texas?
The jail and fine ranges do not change for commercial drivers. The license consequences do, and so does the list of ways a case can be resolved. These are statutory limits, not predictions for any one driver.
For a conviction, refusal or failed test, in any vehicle.
0.08 applies in a personal vehicle.
- Classification
- Class B misdemeanor for a first DWI under Penal Code § 49.04, rising with prior convictions and aggravating facts.
- Jail, first DWI
- 72 hours to 180 days.
- Fine, first DWI
- Up to $2,000, plus court costs.
- Commercial license
- One year, three years with hazardous materials, lifetime on a second qualifying offense (§ 522.081).
- Deferred adjudication
- Barred for a person who held a commercial license or learner's permit at the time of the offense (art. 42A.102).
- Occupational license
- A court order for an occupational license has to bar operating a commercial motor vehicle (§ 521.248), so it does not restore the CDL.
- Employer notice
- A conviction in any vehicle must be reported to the employer in writing within 30 days (49 C.F.R. § 383.31).
- Ordinary license
- A separate suspension of 90 days to one year can follow a first conviction, and an ALR suspension can start earlier.
A plea that looks small on paper can still be a qualifying offense for the commercial license, so the exact offense of conviction is read against the § 522.081 list before any plea.
Real Questions
What Do People Ask About A CDL DWI In Texas?
Does the ALR case threaten my CDL separately?
Can I drive a truck on an occupational license?
Does it matter if I was off duty or in my own truck?
What about my employer's testing program?
Possible Defenses
How Can A CDL DWI Be Defended?
A commercial driver's defense has two tracks. One is the criminal DWI, which turns on the stop, the testing and what the state can prove about intoxication. The other is the license, where the question is whether a disqualifying event can be established at all.
An attorney reads both files together, because a choice on one affects the other. No result can be promised.
The vehicle and the paperwork matter more for a CDL.
Federal definitions decide whether a vehicle counts as a commercial motor vehicle, using things like gross weight, passenger capacity and placarded cargo. A 0.04 case depends on that label, and so does the three year hazardous materials period.
During the county's No Refusal program periods, a refusal can lead to a warrant application as well as a disqualification ground. Multi agency DWI task forces run several times a year with seventeen or more participating agencies from Montgomery and Harris Counties.
Was It A Commercial Vehicle?
Does the vehicle meet the definition that triggers the 0.04 threshold or the hazmat period?
The Stop Or Inspection
Was there a lawful basis for the stop, or for a roadside inspection that led to the contact?
The Test
Was the breath or blood specimen collected, stored and analyzed correctly?
The Refusal
Was the statutory warning given before a refusal was recorded?
The Offense Of Conviction
How would a proposed plea be counted against the § 522.081 list?
Employer Reporting
What has to be reported, to whom, and by what date?
Local Process
What Happens After A CDL DWI Arrest In Montgomery County?
Criminal procedure is the same statewide, and the commercial license rules come from state and federal law. The court, the prosecutor and the jail are the parts that belong to Montgomery County.
Arrest And Notice
The officer arrests the driver, may ask for a specimen and serves a notice of suspension after a failed test or refusal. The ALR request is due 15 days after the notice is received.
Booking And The Magistrate
The driver is booked and brought before a magistrate, who explains the charge and sets bond.
The License Hearing
A judge of the State Office of Administrative Hearings decides whether the suspension is sustained, and that ruling feeds the commercial license record.
The Criminal Case
The state's evidence is requested, motions are heard, and the case resolves by dismissal, a plea that avoids a qualifying offense where possible, or trial.
- Where it is filed
- A misdemeanor DWI is filed in one of the Montgomery County Courts at Law and prosecuted by Montgomery County District Attorney's Office. A felony is heard in the district courts at the Montgomery County Criminal Justice Center on 207 W Phillips St, prosecuted by the Montgomery County District Attorney's Office.
- Who makes the arrest
- Conroe Police Department, Montgomery County Sheriff's Office, Texas DPS Highway Patrol, Montgomery County Constables, Precincts 1 through 5, Willis Police Department, Shenandoah Police Department, Oak Ridge North Police Department, Magnolia Police Department, Splendora Police Department, or Roman Forest Police Department.
- Where you are booked
- The Montgomery County Jail at 1 Criminal Justice Drive, run by the Montgomery County Sheriff's Office.
- If the case is appealed
- Appeals go to the Ninth Court of Appeals in Beaumont.
The ALR hearing page covers the one place to challenge an administrative disqualification before it takes effect. Drivers licensed in another state face the same federal framework, covered on the out of state DWI page.
Next Steps
What Should You Do After A DWI As A Commercial Driver?
Two clocks start together for a commercial driver, one for the license and one for the criminal case. These steps are general information, not advice for any one person.
Count 15 Days
Find the date on the notice of suspension and count 15 days. Ask about the ALR request right away.
Know Your Vehicle
Write down what you were driving, its weight and any placarded cargo, since the classification can change the period.
Read The Employer Policy
Read your employer's written drug and alcohol policy and note any reporting deadline it sets.
Hold Off On Pleas
Do not agree to any plea before the offense is checked against the disqualification list.
Track The 30 Days
If a conviction happens, the written employer notice is due within 30 days of it.
Keep Every Paper
Save the notice, bond papers, test paperwork and the citation.
A plea that seems small for a regular driver can end a commercial career, and it cannot be taken back. Mitchell Law Firm offers a confidential conversation about a commercial driver's DWI charge in Montgomery County. The collateral consequences page covers what else a conviction touches.

Common Questions
Commercial Driver DWI Questions People In Conroe Ask
Can a DWI in my own pickup cost my CDL in Conroe, TX?
Texas Transportation Code § 522.081 disqualifies a commercial license holder from driving a commercial motor vehicle after a DWI conviction in any vehicle, including a personal one. A result of 0.08 or more in a personal vehicle, or a refusal to test, is also a listed ground. A first disqualification lasts one year, or three years where hazardous materials were involved.
Why does 0.04 matter for a commercial driver in Montgomery County?
Section 522.081 uses an alcohol concentration of 0.04 as the threshold when a person is operating a commercial motor vehicle. That figure governs the commercial license only. The criminal DWI offense is separate, and it still requires a concentration of 0.08 or more, or a loss of normal use of mental or physical faculties.
Is deferred adjudication available to a CDL holder charged with DWI in Montgomery County?
Code of Criminal Procedure article 42A.102 bars deferred adjudication for a DWI when the defendant held a commercial driver's license or a commercial learner's permit at the time of the offense. Federal rules also forbid a state from masking a commercial driver's conviction. Dismissal, a reduction to a different charge, a plea and trial remain outcomes that exist in the system.
What does a refusal on a No Refusal weekend mean for a CDL in Conroe, TX?
Refusing a breath or blood test is a listed ground for commercial disqualification under § 522.081. During Montgomery County's No Refusal periods, a refusal can also lead to a blood warrant application reviewed by an on-call judge. The refusal and any warrant draw that follows are separate events in the file, and each can matter to the license.
How long is a CDL disqualified after a DWI in Conroe, TX?
Under § 522.081, a first qualifying offense disqualifies a driver from operating a commercial motor vehicle for one year. The period is three years if the vehicle was placarded for hazardous materials, and a second qualifying offense leads to a lifetime disqualification. These periods run apart from any sentence in the criminal case.
Do I have to tell my employer about a DWI if I hold a CDL in Conroe, TX?
Federal rule 49 C.F.R. § 383.31 requires a commercial license holder convicted of a non-parking traffic violation, in any type of vehicle, to notify the current employer in writing within 30 days of the conviction. The duty follows the conviction, so the way a case ends decides when that clock starts.
