Commercial DWI

People who drive trucks or buses professionally are subject to some laws that do not apply to other drivers. Both federal and Texas laws hold commercial drivers to a higher standard regarding alcohol consumption, with lower thresholds of legal impairment than for other drivers.

The Federal Motor Carrier Safety Administration (FMCSA), a division of the U.S. Department of Transportation (USDOT) has established that the operation of a commercial vehicle by a driver with a blood-alcohol concentration (BAC) of 0.04 or more is illegal (49 Code of Federal Regulations, Section 382.201). Section 522.081 of the Texas Statutes mirrors the federal threshold of 0.04, which is half the legal maximum threshold for non-commercial drivers (0.08).

A person with a commercial driver's license (CDL) who has a BAC of 0.04 or more in Texas while driving a commercial vehicle is legally considered a drunk driver and may be arrested for DWI (driving while intoxicated), even when the BAC level is below 0.08. In addition, a commercial driver who exceeds the 0.08 threshold when driving a personal vehicle will lose his or her CDL for a year, which will result in job loss as a professional driver.

Other penalties for "Commercial DWI" include jail, heavy fines, and probation, as well as DWI "surcharges."

Civil Penalties for Commercial DWI in Texas

People convicted of Commercial DWI in Texas face numerous penalties — both criminal and civil — although the potential civil consequences may be harsher because they include a CDL suspension, which may result in the loss of a job as a commercial driver. A CDL may be suspended for a period of one year to life, depending on the severity of the violation.

One Year CDL Suspension for First Commercial DWI

Under Texas law, a person who holds a commercial driver's license is disqualified from driving a commercial motor vehicle for one year upon a first conviction:

  • For driving a motor vehicle under the influence of alcohol or a controlled substance;
  • For refusing to submit to a test to determine the person's alcohol concentration or the presence in the person's body of a controlled substance or drug while operating a motor vehicle in a public place;  or
  • If an analysis of the person's blood, breath, or urine determines that the person:
    • Had an alcohol concentration of 0.04 or more, or that a controlled substance or drug was present in the person's body, while operating a commercial motor vehicle in a public place;  or
    • Had an alcohol concentration of 0.08 or more while operating a motor vehicle, other than a commercial motor vehicle, in a public place

Three Year CDL Suspension for DWI with Hazardous Material

A person who holds a commercial driver's license is disqualified from operating a commercial motor vehicle for three years if:

  • Convicted of driving a motor vehicle under the influence of alcohol in a vehicle transporting a hazardous material required to be placarded or if the driver refuses to submit to a test to determine the driver's alcohol concentration or the presence in the person's body of a controlled substance or drug, or;
  • An analysis of the person's blood, breath, or urine determines that while transporting a hazardous material required to be placarded that the person:
    • While operating a commercial motor vehicle in a public place had an alcohol concentration of 0.04 or more, or a controlled substance or drug present in the person's body;  or
    • While operating a motor vehicle, other than a commercial motor vehicle, in a public place had an alcohol concentration of 0.08 or more.

Lifetime CDL Suspension Multiple Convictions and Other Crimes

A person who holds a commercial driver's license is disqualified from operating a commercial motor vehicle for life if:

  • The person is convicted two or more times of certain offenses specified in the statutes or a combination of those offenses, arising from two or more separate incidents; or
  • The person uses a motor vehicle in the commission of a felony involving:
    • The manufacture, distribution, or dispensing of a controlled substance; or
    • Possession with intent to manufacture, distribute, or dispense a controlled substance; or
  • The person uses a motor vehicle in the commission of an offense that involves the transportation, concealment, or harboring of an alien

(See Texas Statutes, Title 7, Chapter 522.081.)

Texas law provides for an appeals process for CDL suspensions, but a lifetime CDL suspension may not be appealed for 10 years (Texas Statutes, Title 7, Chapter 522.082).

The Texas licensing bureau will determine a person's eligibility for CDL restoration after 10 years. But if a reinstated driver is ever convicted of a similar offense, he or she will permanently lose his or her CDL with no possibility of reinstatement.

Texas DWI Surcharges

In addition to the criminal penalties that may be imposed after a Commercial DWI conviction, Texas also assesses a mandatory annual DWI surcharge fee to be paid to the Texas Department of Public Safety (DPS). This administrative fee must be paid for a period of three years as a condition of maintaining a driver’s license. Failure to pay the surcharges or enter into a payment agreement will result in the automatic suspension of a CDL until all payments are made.

Texas DWI surcharges, to be paid to the Texas Department of Public Safety, are:

Client Testimonials

I can’t say enough great things about the attorneys at this law firm. Within a few months they had my case, which I thought I was going to lose, dismissed and put my life back on track. I would recommend their firm to anyone and everyone who is in need of legal help.

Leslie L. Denton County DWI

A few months before I moved out of Texas, I was arrested for DWI. The problem was I was building a new life in another state with greater opportunities. I needed to find an attorney to handle my special situation being an out of state client who also travels out of the country. My case was in Denton County, which I have heard is a very difficult county to deal with. Because of my job I was in need of special accommodations from the court so I would not lose my career. After several months of tough negotiations with the DA, Richard and Brian were able to finalize my case beyond my expectations. I would highly recommend this law firm to anyone who has run into some trouble anywhere they might get a DWI.
