In Texas, the legal limit for blood alcohol concentration (BAC) 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 threshold. The 0.08% limit is established to ensure that drivers maintain a level of alertness and coordination necessary for safe driving.

Driving under the influence of alcohol can significantly impair one's ability to operate a vehicle, affecting reaction times, judgment, and coordination. The BAC limit is a crucial regulation to help reduce the incidence of alcohol-related traffic accidents and fatalities.

It's important to note that even at lower BAC levels, a person can still be charged with driving while intoxicated (DWI) if their ability to drive is visibly impaired. The legal system recognizes the risks associated with alcohol consumption and its impact on driving safety, making it essential for drivers to understand and adhere to these regulations.
