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 over the age of 21 is 0.08%. This means that a driver is considered legally impaired if their BAC is at or above this level. The rationale behind the 0.08% limit is based on research indicating that this level of intoxication significantly impairs a person's ability to operate a vehicle safely. At this BAC level, drivers may experience reduced coordination, slower reaction times, and diminished judgment, all of which increase the risk of accidents on the road.

Setting the limit at 0.08% is meant to provide a clear and enforceable standard that supports public safety and helps deter individuals from driving under the influence. Drivers are encouraged to be responsible and make alternate arrangements for transportation if they have consumed alcohol, even if their BAC is below this threshold, as impairment can begin at lower levels.
