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

In Texas, the legal blood alcohol concentration limit for drivers aged 21 and over is 0.08%. This level is established as the threshold for driving under the influence (DUI) of alcohol. When an individual's BAC reaches or exceeds this limit, they are considered impaired and are subject to arrest and penalties, including fines, license suspension, and possible imprisonment.

This regulation aims to enhance road safety by reducing the risk of accidents caused by impaired driving. The 0.08% limit aligns with the federal standard, reinforcing a uniform approach to drinking and driving laws across the country. Understanding this limit is crucial for responsible alcohol consumption and ensuring public safety on Texas roads.
