What is the maximum legal limit for blood alcohol concentration (BAC) for drivers operating commercial vehicles in Ontario?

The maximum legal limit for blood alcohol concentration (BAC) for drivers operating commercial vehicles in Ontario is set at 0.00%. This means that any detectable amount of alcohol in the bloodstream is not permissible for commercial drivers. The reason for this strict regulation is to ensure the safety of all road users, as commercial drivers are responsible for larger vehicles that can pose a significant risk if operated under the influence of alcohol.

For non-commercial drivers in Ontario, different limits apply, where a BAC of 0.05% may still permit driving under certain circumstances. However, for commercial drivers, the zero-tolerance policy reflects the higher standards of safety expected in the operation of commercial vehicles. This also discourages any consumption of alcohol before or during driving, thus promoting safer driving practices in the industry.
