How Prosecutors Prove a DWI in Texas

Under Texas law, a prosecutor only needs to prove one of the following:

  • You lacked the normal use of mental or physical faculties due to alcohol, a controlled substance, a drug, a dangerous drug, or a combination of substances; or
  • You had a blood alcohol concentration (BAC) of .08% or higher


This means:

  • You can be convicted with a BAC below .08
  • You can be convicted without giving a breath sample
  • A refusal does not automatically protect you


Because of how broadly Texas defines intoxication, hiring an experienced Houston DWI lawyer is critical.
