What is the legal blood alcohol concentration (BAC) limit for adults in Texas?

The legal blood alcohol concentration (BAC) limit for adults in Texas is 0.08%. This standard applies to drivers aged 21 and over, indicating that any driver found with a BAC at or above this level is considered legally intoxicated and can be charged with driving under the influence (DUI). The rationale behind setting the limit at 0.08% is based on research that shows significant impairment in motor skills and judgment at this level of intoxication, which can lead to dangerous driving conditions.

Other BAC levels provided in the options are not applicable to the general adult driving population in Texas. For instance, a BAC of 0.02% may be relevant in certain situations, like for underage drivers or specific restricted licenses, but it is not the threshold for adult drivers. Similarly, levels of 0.10% and 0.05% exceed the legally permissible limit for adults, reinforcing the importance of understanding and adhering to the established legal standards for safe driving.
