What is the maximum blood alcohol concentration (BAC) level for drivers with a Class 4 license in Alberta?

For drivers with a Class 4 license in Alberta, the maximum blood alcohol concentration (BAC) level is indeed 0.00%, which indicates a zero-tolerance policy. This means that any presence of alcohol in the bloodstream while operating a vehicle is not allowed, prioritizing the safety of all road users.

In Alberta, this strict rule applies particularly to drivers who hold a Class 4 license, which allows them to operate vehicles for commercial purposes, such as taxis, buses, or other services involving transporting passengers. The intention behind implementing a zero-tolerance policy is to minimize the risks associated with impaired driving, especially in a professional capacity where the driver's actions directly impact the safety and well-being of others.

Other BAC limits, such as 0.02%, 0.05%, or 0.08%, are relevant for different classes of licenses or situations. However, the Class 4 licenseholder’s requirement for a 0.00% BAC emphasizes the heightened responsibility they carry on the road.
