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

The legal blood alcohol concentration (BAC) limit for drivers over 21 in Texas is 0.08%. This standard is widely recognized and enforced as the threshold at which a driver is considered impaired in terms of their ability to operate a vehicle safely. The establishment of this limit serves to promote road safety by reducing the incidence of accidents related to alcohol consumption.

Setting the BAC limit at 0.08% is based on research that indicates that impairment significantly affects motor skills and judgment at this level. Therefore, if a driver's BAC is at or above this limit, they are subject to DUI or DWI charges, reflecting a serious violation of traffic laws aimed at protecting both the driver and others on the road.

The other BAC levels listed are not applicable as legal limits for drivers over 21 in Texas, as they fall below or exceed the established standard.
