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

In Texas, the legal blood alcohol concentration (BAC) limit for drivers aged 21 and older is set at 0.08%. This means that if a driver's BAC is at or above this level, they are considered legally intoxicated and can face penalties such as fines, license suspension, and even incarceration if apprehended driving under the influence. This threshold is established to promote road safety and minimize the risks associated with impaired driving.

The choice of 0.08% is widely recognized across many states in the U.S., aligning with federal guidelines to standardize drunk driving laws. It reflects a level of impairment where the driver's ability to operate a vehicle safely is significantly compromised, making it an important legal benchmark.
