Yes, the word intoxicated for purposes of the CHL statute is undefined in Texas Penal Code Chapter 46. However, as a practical matter, most district attorneys' offices will use the definition of intoxication from Chapter 49, which means intoxication can be proven three ways.
It can either be shown to be a blood alcohol concentration of .08 or greater, or the consumption of an intoxicant to the degree that it causes the loss of the normal use of a person's mental faculties or physical faculties.
Thank you for the question.
