  1. A0.05%
  2. B0.10%
  3. C0.02%
  4. D0.08%
Show answer & explanation

Correct answer: D. 0.08%

In Texas, for drivers 21 years of age or older, a Blood Alcohol Concentration (BAC) of 0.08% or higher is the legal threshold for intoxication.

Why the other options are wrong

  • A. 0.05% is not the legal limit for intoxication in Texas for drivers 21 or older.
  • B. 0.10% is above the legal limit, but 0.08% is the specific threshold.
  • C. 0.02% is typically the 'zero tolerance' limit for drivers under 21, not the legal intoxication limit for adults.

Texas Legal BAC Limit (Adults)

In Texas, a driver aged 21 or older is considered legally intoxicated if their Blood Alcohol Concentration (BAC) is 0.08% or higher.

  • Applies to drivers 21 years or older.
  • Below 0.08% can still result in DWI if impaired.
  • Penalties include fines, jail time, license suspension.
