The maximum legal blood alcohol concentration (BAC) limit for commercial drivers is 0.04% or lower. This limit is established to ensure the safety of both the driver and the public due to the inherent responsibilities that come with operating large vehicles. Commercial drivers are held to a stricter standard compared to non-commercial drivers because they often operate vehicles that can cause significant harm in the event of an accident.

The regulatory environment for commercial drivers recognizes that alcohol impairs judgment, reaction times, and overall driving ability, making it essential to maintain a lower threshold for alcohol consumption. This standard reflects the importance placed on safety in the trucking industry, where drivers must be alert and able to respond quickly to changing road conditions and emergencies.

While other BAC limits exist for general driving, they do not apply to those with commercial driver's licenses, emphasizing the need for heightened caution in commercial vehicle operations.
