What is the maximum permissible BAC for commercial drivers in Texas?

In Texas, the maximum permissible blood alcohol concentration (BAC) for commercial drivers is set at 0.04%. This standard is significantly lower than the 0.08% limit that applies to non-commercial drivers. The rationale behind this stricter limit is to enhance safety on the roads since commercial drivers are often responsible for operating larger vehicles, such as buses or trucks, which can cause more significant harm in the event of an accident. This regulation reflects the heightened responsibility and the potential for severe consequences that come with driving commercial vehicles.

Different limits apply to various categories of drivers, particularly those holding a commercial driver’s license (CDL). For example, the 0.02% limit is applicable for underage drinking, and the higher limits of 0.08% reflect standards for private individuals. Adhering to the 0.04% BAC limit for commercial drivers is critical to maintain safety standards and enforce regulation in the transportation industry.
