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

The maximum blood alcohol concentration (BAC) allowed for commercial drivers is 0.04%. This regulation is in place to ensure a high standard of safety on the roads, as commercial drivers operate large vehicles and have a higher responsibility for the safety of themselves, their passengers, and other road users. At or above this BAC level, commercial drivers are considered impaired and can face legal consequences, including fines, suspension of their CDL, or even criminal charges.

The lower limit for commercial drivers, compared to non-commercial drivers, reflects the increased risks associated with operating larger vehicles that require more skill and focus. This not only helps to minimize the potential for accidents but also fosters a culture of safety within the commercial driving industry. The BAC levels for non-commercial drivers can be higher, as shown by the other choices, reflecting the varying standards for different types of drivers.
