Ontario Bus Driver Knowledge Practice Test 2025 – All-in-One Study Guide for Exam Success!

In Ontario, the legal blood alcohol concentration (BAC) limit for bus drivers is set at 0.00%. This means that bus drivers must have no measurable amount of alcohol in their system while operating a vehicle. This stringent regulation is in place to ensure the safety of passengers and others on the road, given the high level of responsibility involved in driving a bus.

Bus drivers, as well as other commercial vehicle operators, are held to a higher standard compared to the general public, where the BAC limit is 0.08% for most drivers. By enforcing a zero-tolerance policy, the law aims to minimize any risk associated with alcohol consumption, thereby protecting the communities they serve.

A BAC of 0.02% or higher would indicate the presence of alcohol, which does not align with the zero-tolerance requirement for bus drivers. This is why having a BAC limit of 0.00% is essential in maintaining public safety and upholding the integrity of public transportation services in Ontario.
