According to the Graduated Licensing System, what is the maximum Blood Alcohol Concentration allowed for a supervising driver?

The correct understanding of the Graduated Licensing System in Ontario dictates that the maximum allowable Blood Alcohol Concentration (BAC) for a supervising driver is 0.00 g%. This strict regulation is in place to ensure that the supervising driver is completely sober, as their role is to provide guidance and support to a new driver who is still in the learning phase of acquiring their driving skills.

Allowing any level of alcohol in the supervising driver's system could compromise their ability to effectively assist the learner, and may also create unsafe conditions on the road. The emphasis on a BAC of 0.00 reinforces the commitment to safety during the initial stages of a new driver’s education, ensuring that they receive clear and safe supervision without the influence of alcohol.

In contrast, other BAC levels suggest a tolerance for some degree of alcohol consumption, which runs counter to the objectives of the Graduated Licensing System.
