Commercial Driver’s License DWIs in Texas | What to Know

If you drive a commercial vehicle, it is important to understand Texas’ DWI laws. Read on to learn more about DWI penalties for drivers with commercial licenses.

What Constitutes a Commercial Driver’s License (CDL) DWI in Texas?

The first thing you should understand is that the bar for DWIs is higher for commercial drivers in Texas than for standard automobile drivers. For example, you can receive a DWI for operating a commercial vehicle with a Blood Alcohol Concentration (BAC) of just .04%. Comparatively, if you have a standard driver’s license, you may be charged with a DWI if you have a BAC of .08%. That being said, if you are charged with a first-offense DWI with a CDL in Texas, you are looking at a Class B Misdemeanor that comes with very serious penalties.

What are the Penalties of a First Offense CDL DWI in Texas?

If you are charged with a CDL DWI for the first time, you may face the following penalties:

  • A potential one-year suspension of your commercial driver’s license
  • Up to 180 days in jail
  • A $2,000 fine

You should also understand that if you were arrested for a DWI while operating a commercial vehicle that was transporting hazardous materials, you will most likely lose your commercial driver’s license for an even longer period of time. In most cases, you will lose your commercial license for 3 years.

What Happens if I Am Charged with a Second CDL DWI?

If you are charged with a second CDL DWI offense in Texas, you will most likely lose your commercial driver’s license forever. If you are someone who drives for a living, this can seriously impact your livelihood.
