What is the maximum Blood Alcohol Concentration (BAC) level permitted for commercial drivers in Texas?

The maximum Blood Alcohol Concentration (BAC) level permitted for commercial drivers in Texas is 0.04% BAC. This is significantly stricter than the general legal limit of 0.08% BAC for non-commercial drivers. The reasoning behind this low limit for commercial drivers stems from the increased responsibility they hold when operating large vehicles, such as trucks or buses, that can pose greater risks to public safety.

A BAC of 0.04% indicates impairment that could potentially affect a commercial driver's ability to safely operate their vehicle, hence, the law aims to maintain higher safety standards in the commercial driving sector. Consequently, commercial drivers are held to stricter regulations to ensure that they remain alert and capable while performing their duties on the road. This lower threshold emphasizes the importance of safety in transportation involving commercial vehicles.
