Texas Defensive Driving Written Practice Test 2025 – Comprehensive All-in-One Guide to Success!

The legal blood alcohol concentration (BAC) limit for drivers over 21 in Texas is 0.08%. This limit is established to ensure that drivers are not impaired while operating a vehicle, as even small amounts of alcohol can affect judgment and reaction times. The 0.08% threshold is widely recognized across many states as the standard for determining legal intoxication, and driving with a BAC at or above this level can result in legal penalties, including fines, license suspension, and even jail time. Understanding this limit is crucial for responsible driving and maintaining safety on the roads.
