How does Texas law define “driving while intoxicated” (DWI)?

The definition of “driving while intoxicated” (DWI) under Texas law specifically includes two key components: operating a motor vehicle in a public place while intoxicated, or having a blood alcohol concentration (BAC) of 0.08% or more. This legal framework is designed to address both impairment caused by alcohol consumption and the specific quantifiable measure of blood alcohol that indicates a level of intoxication.

By stating that a BAC of 0.08% or more constitutes DWI, Texas law provides a clear and objective standard that facilitates enforcement and prosecution. It helps law enforcement officers determine whether an individual is legally considered impaired, irrespective of subjective interpretations of behavior or driving patterns.

The other options do not encompass the full legal definition of DWI as understood in Texas. For instance, while prescription drugs can impair a person's ability to drive, the definition specifically emphasizes intoxication and a certain BAC threshold. Similarly, driving recklessly or consuming any amount of alcohol may contribute to unsafe driving but does not directly align with the legal parameters defining DWI in Texas. By focusing on both operational behavior (driving while intoxicated) and measurable impairment (BAC), option B accurately reflects the stipulations of Texas law regarding DWI.
