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

The legal alcohol limit for drivers over 21 in Texas is set at 0.08% blood alcohol concentration (BAC). This means that if a person's BAC measures at or above this level while operating a vehicle, they may be considered legally impaired and subject to penalties, including fines, license suspension, or even jail time. The 0.08% limit is widely used across many states in the U.S., reflecting a consensus that at this level, many individuals will experience an impairment of their abilities to drive safely.

Other BAC levels mentioned, such as 0.04% or 0.10%, do not hold legal significance for drivers over 21; instead, 0.04% applies to commercial drivers, while 0.10% is above the legal limit for standard drivers. A BAC of 0.07% is also below the legal limit but still indicates that a driver could be charged with DWI if they were exhibiting signs of impairment. Thus, understanding the 0.08% legal limit is crucial for responsible driving and safety on the roads.
