What is the maximum BAC for commercial drivers operating a commercial vehicle?

The maximum Blood Alcohol Concentration (BAC) for commercial drivers operating a commercial vehicle is set at 0.04. This limit is significantly lower than the standard limit of 0.08 for non-commercial drivers because the federal regulations ensure a higher standard of safety for commercial vehicle operation.

Commercial drivers are held to this stricter BAC limit due to the nature of their work, which often involves larger vehicles and greater responsibilities, such as transporting goods or passengers. At a BAC of 0.04, a driver is considered impaired and therefore poses a risk to road safety. Stricter regulations for commercial drivers emphasize the importance of maintaining a higher level of alertness and performance while operating a commercial vehicle.
