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

• A. 0.10%
• B. 0.08%
• C. 0.05%
• D. 0.12%

Answer: (B)

The legal blood alcohol concentration (BAC) limit for drivers over 21 in Texas is 0.08%. This threshold is established to enhance road safety by ensuring that drivers maintain a level of alertness and reaction time that is crucial for safe driving. A BAC at or above 0.08% significantly impairs a person's ability to operate a vehicle safely, increasing the risk of accidents and endangering both the driver and others on the road. The other options represent BAC levels that either have no legal standing for adult drivers or are below the threshold deemed acceptable for safe driving. For instance, while a BAC of 0.05% is considered lower than the legal limit, it is still important to note that even at this level, drivers can be charged with DWI (Driving While Intoxicated) if their driving ability is impaired. The choices of 0.10% and 0.12% are above the legal limit and would inevitably result in legal consequences if a driver operated a vehicle at those levels. Thus, understanding the 0.08% limit is crucial for compliance with Texas law and to ensure safe driving practices.
