SmartServe Ontario Practice Exam

In Ontario, a Blood Alcohol Concentration (BAC) level of 0.08% or higher is legally considered a criminal offence for drivers. This threshold is part of Canada's regulations concerning driving under the influence of alcohol. When a person's BAC reaches this level, they are deemed unable to operate a motor vehicle safely due to impaired judgment and motor skills, increasing the risk of accidents. The BAC levels mentioned in the other options, while they may indicate impairment, do not meet the legal threshold for a criminal offence in Ontario. This is why 0.08% is significant; it marks the line at which driving becomes illegal from a legal standpoint, and penalties for being above this limit can include fines, license suspension, and potentially more severe consequences.
