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

The legal blood alcohol concentration (BAC) limit for drivers over 21 in Texas is 0.08%. This threshold is established by state law and is consistent with federal regulations. When a driver has a BAC of 0.08% or higher, they are considered impaired and can be charged with driving while intoxicated (DWI). This legal limit is crucial as it protects both the driver and other road users by ensuring that individuals operating vehicles are not under the influence of alcohol to a degree that significantly impairs their motor skills or judgment.

The other options represent lower BAC levels that, while still possibly requiring caution, do not constitute the legal limit for driving in Texas. A BAC of 0.02%, for example, may still lead to penalties if the driver shows signs of impairment, but it is not the legal threshold for intoxication. Understanding this limit is essential for responsible driving and alcohol consumption.
