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

In Texas, the legal blood alcohol concentration (BAC) limit for drivers over the age of 21 is 0.08%. This standard is in line with laws across the United States, as 0.08% BAC is widely recognized as the threshold where impairment begins to significantly impact a person's ability to operate a vehicle safely. At this level, a driver may exhibit decreased coordination, judgment, and reaction times, elevating the risk of accidents. The law was established to ensure public safety on the roads, effectively balancing personal freedoms with the need to protect all drivers and pedestrians.

Other options present varying limits that do not align with Texas law. Limits below 0.08%, while they may be relevant in specific contexts, do not represent the legal threshold for a DUI charge. Limits above this mark indicate a higher degree of impairment and are not permissible under Texas statutes for drivers in this age group.
