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 21 years of age and older is set at 0.08%. This means that if a driver has a BAC of 0.08% or higher, they are considered legally impaired and can be charged with driving while intoxicated (DWI). The BAC limit is established to promote road safety by reducing the risk of accidents caused by impaired driving.

Setting the limit at 0.08% balances the need for safe driving with the recognition that alcohol affects individuals differently. Factors such as body weight, metabolism, and drinking habits can impact an individual's level of impairment. Hence, the established legal limit serves as a guideline for law enforcement and offers a measurable standard to enforce impaired driving laws effectively.

The other BAC levels listed are not recognized as legal limits for adult drivers in Texas; therefore, they do not apply.
