Texas refers to drunk driving or alcohol-based driving offenses as DWI, and penalties include fines, jail time, and license suspension. The legal limit for drivers is below .08% BAC, but those with lower BAC may still find themselves facing consequences depending on the circumstances of the incident. Some offenders are able to regain driving privileges by installing an ignition interlock device from an approved provider. This guide will explain the interlock policy in Texas.What Are the Penalties for DWI in Texas?
