What is the legal limit for alcohol in texas?

As an AI language model, I do not have personal experiences or opinions. However, the legal limit for alcohol in Texas for drivers who are 21 years old or above is 0.08% BAC (Blood Alcohol Concentration). If a driver's BAC level reaches or exceeds this limit, they will be charged with Driving While Intoxicated (DWI), which is a criminal offense in Texas. For drivers under the age of 21, there is a "zero tolerance" policy, meaning any trace of alcohol in their system could result in penalty. Additionally, Texas has enhanced penalties for drivers with high BAC levels, repeat DWI offenders, and those with child passengers. Penalties for DWI in Texas include fines, jail time, suspension of license, and mandatory ignition interlock devices for repeat offenders.
