What is the legal Blood Alcohol Concentration (BAC) limit for drivers aged 21 and over in Texas?

  1. 0.05%

  2. 0.08%

  3. 0.10%

  4. 0.12%

The correct answer is: 0.08%

In Texas, the legal Blood Alcohol Concentration (BAC) limit for drivers aged 21 and over is 0.08%. This limit is established to promote road safety and reduce the number of alcohol-related accidents. A BAC of 0.08% indicates that a driver’s ability to operate a vehicle may be significantly impaired, which can lead to dangerous driving behaviors such as decreased reaction times, poorer judgment, and impaired coordination. This standard is in line with national guidelines, as the 0.08% limit is widely adopted across the United States as the threshold for impaired driving for individuals of legal drinking age. Therefore, it is crucial for drivers to understand and adhere to this limit to ensure not only their safety but the safety of others on the road.
