What is the legal blood alcohol concentration (BAC) limit for drivers over 21 in Ontario?

The legal blood alcohol concentration (BAC) limit for drivers over 21 in Ontario is 0.08%. This means that if a driver's BAC is 0.08% or higher, they are considered legally impaired and can be charged with DUI (driving under the influence). This threshold is established to ensure public safety, as higher levels of alcohol consumption significantly impair a driver's ability to operate a vehicle safely, increasing the risk of accidents.

The 0.08% limit is a widely accepted standard for adult drivers in many jurisdictions, reflecting a level at which impairment is likely to affect driving performance. For drivers who are younger or those who have graduated from certain programs, lower limits may apply, emphasizing the additional caution required for inexperienced drivers. It's crucial for drivers to understand these regulations, as they are designed to prevent alcohol-related accidents and promote road safety.
