What is the legal blood alcohol concentration (BAC) limit for drivers over 21 in Texas?

In Texas, the legal blood alcohol concentration (BAC) limit for drivers who are over 21 years old is set at 0.08%. This standard aligns with the national guidelines for driving under the influence, indicating that at this level, a person's ability to operate a vehicle safely is significantly impaired.

Having a BAC of 0.08% means that for every 100 milliliters of blood, there are 0.08 grams of alcohol, which can affect driving skills such as reaction time, motor coordination, and judgment. Driving with a BAC at or above this threshold can lead to strict penalties, including fines, license suspension, and potential jail time.

The other BAC options are lower than the legal limit for those over 21. While lower levels may not be illegal, they still carry risks of impairment and legal consequences when combined with other factors, such as driver behavior and driving conditions.
