What code clearly defines "intoxication" as it applies to the state of Texas?

In Texas, "intoxication" is specifically defined within the Texas Penal Code. This legal framework outlines various criminal offenses, including those related to driving while intoxicated (DWI). The definition encompasses not just alcohol impairment but also drug-related impairment, providing clarity on what constitutes intoxication under the law. Understanding this definition is crucial for comprehending the regulations surrounding impaired driving and the legal implications that follow.

The other choices refer to different areas of law or regulations. The Texas Vehicle Code primarily relates to laws governing vehicles and their operation, while the Texas Traffic Law encompasses specific rules of the road and traffic regulations. The Texas Safety Code covers a broader range of safety laws but does not specifically address the definitions of intoxication in relation to driving offenses. Thus, the Texas Penal Code is the correct reference point for defining intoxication in Texas.
