DWI/DUI

 Texas Law on DWI/DUI

​Under Texas Penal Code § 49.04, a non-commercial driver is considered legally intoxicated and may be arrested and charged with a DWI (Driving While Intoxicated) when they are operating a motor vehicle in a public place with a .08 BAC (blood or breath alcohol concentration) or higher. Commercial drivers operating a motor vehicle in a public place with a .04 BAC or higher are considered legally intoxicated and may be arrested and charged with a DWI. 

Under Texas law, "intoxicated" means not having the normal use of mental or physical faculties due to the consumption of alcohol, drugs, or a combination of those substances, or having a .08 BAC or higher. Texas law permits the arrest and charge of a person with a DWI if they appear intoxicated or impaired due to alcohol or other drugs regardless of whether the BAC is a .08 or above.

An offense under Texas Penal Code § 49.04 is a Class B misdemeanor, with a minimum term of confinement of 72 hours. If it is shown on the trial of an offense under § 49.04 that at the time of the offense the person operating the motor vehicle had an open container of alcohol in the person's immediate possession, the offense is a Class B misdemeanor, with a minimum term of confinement of six days. If it is shown on the trial of an offense under § 49.04 that an analysis of a specimen of the person's blood, breath, or urine showed an alcohol concentration level of 0.15 or more at the time the analysis was performed, the offense is a Class A misdemeanor.
