What is the maximum allowed blood alcohol concentration (BAC) for commercial drivers?

The maximum allowed blood alcohol concentration (BAC) for commercial drivers is legally set at 0.04%. This standard is in place because commercial drivers operate vehicles that are larger and heavier than standard passenger cars, which can pose greater risks on the road when the driver is impaired. The lower threshold compared to the general driving limit of 0.08% reflects the heightened responsibility commercial drivers have in ensuring the safety of themselves and others on the road.

Regulations are stringent in the commercial driving sector to prevent accidents caused by impaired driving. A BAC of 0.04% has been established as the maximum level, meaning that even a small amount of alcohol can lead to serious legal repercussions for commercial drivers. This standard aims to promote safe driving practices in the industry, thereby reducing accident rates and enhancing public safety.
