What is the legal blood alcohol concentration (BAC) limit for novice drivers in Ontario?

Answer: A — 0.00%

The legal blood alcohol concentration (BAC) limit for novice drivers in Ontario is 0.00%, which means that novice drivers are not allowed to have any alcohol in their system while operating a vehicle. This means that choices B, C, and D are all incorrect because they suggest that novice drivers are allowed to have some level of alcohol in their system. Having any amount of alcohol in their system can impair a novice driver's ability to safely operate a vehicle, and therefore the law has a strict zero-tolerance policy for novice drivers.
