Commercial DWI

Without a driver's license, a person who drives a truck or a bus for a living is out of a job. A DWI conviction may lead to the suspension of a driver's license, which could apply the brakes to a commercial driver's employment.

Commercial drivers who operate in Texas must hold a commercial driver's license (CDL) and they must follow both federal and state laws. Both federal and Texas laws are stricter for commercial drivers than for other drivers regarding alcohol, with lower limits for legal impairment than for other drivers.

The U.S. Department of Transportation (USDOT), through the Federal Motor Carrier Safety Administration (FMCSA), requires commercial drivers to be sober while on the job. A commercial driver with a blood-alcohol concentration (BAC) of 0.04 or more is considered legally drunk under 49 Code of Federal Regulations, Section 382.201, which is half the legal maximum limit for non-commercial drivers (0.08).

Section 522.081 of the Texas Statutes copies the federal BAC limit of 0.04. 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, also known as driving under the influence [DUI], or drunk driving), even if the person's BAC level is below 0.08.

A commercial driver who exceeds the 0.08 limit when operating his or her personal vehicle will lose his or her CDL for a year, which will usually mean the end of the road as a professional driver. Additional penalties for "Commercial DWI" include the possibility of jail, fines, probation, and expensive DWI "surcharges."

Commercial DWI under Texas Law

In Texas, a commercial truck or bus driver is considered to be driving while intoxicated if he or she has a BAC of 0.04 or higher (Texas Statutes, Transportation Code, Title 7, Subtitle B, Subchapter H, Section 522.081).

A driver operating a commercial motor vehicle 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.

Civil Penalties for Commercial DWI in Texas

Anyone convicted of Commercial DWI in Texas may have to deal with a variety of civil penalties. After a DWI conviction, a person's CDL may be suspended for a period of anywhere from one year to life, depending on the severity of the violation.

One Year CDL Suspension for First Commercial DWI

After a first DWI conviction, a person who holds a commercial driver's license will be disqualified from driving a commercial vehicle for a period of one year:

  • 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 0.08 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 CDL holder charged with DWI will be 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 motor vehicle, other than a commercial motor vehicle, in a public place had an alcohol concentration of 0.08 or more.

Lifetime CDL Suspension for Multiple DWI Convictions and Other Crimes

Under Texas Statutes, Title 7, Chapter 522.081, a CDL holder charged with DWI will be disqualified from operating a commercial motor vehicle for life if:

  • The person is convicted two or more times of DWI 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

A person who received a lifetime CDL suspension may appeal the suspension, as provided in Texas Statutes, Title 7, Chapter 522.082, but only after 10 years. If a driver who is reinstated after a lifetime suspension 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:

  • DWI First Offense  — $1,000 annual surcharge  ($3,000 total)
  • DWI Second or Subsequent Offense — $1,500 annual surcharge ($4,500 total)
  • DWI with BAC 0.16 or more (first offense) — $2,000 annual surcharge  ($6,000 total)
