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.”

Commercial DWI under Texas Law

A commercial motor vehicle driver with an alcohol concentration of 0.04 or higher is considered to be driving while intoxicated under the Texas Statutes, Transportation Code, Title 7, Subtitle B, Subchapter H, Section 522.081.

The law states that any commercial vehicle driver operating a commercial motor vehicle in Texas with an alcohol concentration (BAC) of 0.04 or higher is subject to the same DWI punishments imposed on non-commercial drivers with a BAC of 0.08 or higher.

Definitions of Terms Related to Commercial DWI in Texas

Some of the terms in the commercial DWI law are defined in the Texas statutes, including a commercial motor vehicle, intoxicated, and alcohol concentration.

“Commercial motor vehicle” is defined under federal 49 C.F.R. § 382.107 and Texas Statutes, Transportation Code § 522.003(5) as a motor vehicle or combination of motor vehicles used to transport passengers or property that:

  • Has a gross combination weight or a gross combination weight rating of 26,001 or more pounds, including a towed unit with a gross vehicle weight or a gross vehicle weight rating of more than 10,000 pounds; or
  • Has a gross vehicle weight or a gross vehicle weight rating of 26,001 or more pounds; or
  • Is designed to transport 16 or more passengers, including the driver; or
  • Is transporting hazardous materials.

Under the Texas Penal Code § 49.01(2), “intoxicated” means: 

  • Not having the normal use of mental or physical faculties by reason of the introduction of alcohol, a controlled substance, a drug, a dangerous drug, a combination of two or more of those substances, or any other substance into the body;  or
  • Having an alcohol concentration of 0.08 or more (0.04 for commercial drivers under Texas § 522.081).

Under Texas P.C. § 49.01(1), “alcohol concentration” (also known as blood alcohol concentration or BAC) means the number of grams of alcohol per:

  • 210 liters of breath
  • 100 milliliters of blood, or
  • 67 milliliters of urine.”

Criminal Penalties for Commercial DWI in Texas

A person charged with a commercial DWI in Texas will be subject to the same DWI penalties that a non-commercial driver would face, but a commercial DWI conviction may result in the loss of his or her CDL, which is detailed in the next section.

Driving while intoxicated is considered a Class B misdemeanor in Texas, and penalties include a sentence of at least three days and up to 180 days in jail and/or fines of up to $2,000.

If a driver is found to have a BAC of 0.15 or higher, the charge is elevated to a Class A misdemeanor. If convicted, a Class A misdemeanor is punishable by up to one year in jail and/or fines of up to $4,000.

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:
