In Ontario, Canada, the legal alcohol limit for driving is 80 milligrams of alcohol per 100 milliliters of blood, commonly referred to as 0.08 BAC (Blood Alcohol Concentration). This limit applies to fully licensed drivers who are not in the Graduated Licensing System. For drivers under the age of 21, novice drivers (with a G1, G2, M1, or M2 license), and commercial drivers, the limit is zero – they must have no alcohol in their system while driving. Exceeding these limits can result in serious consequences, including fines, license suspensions, and criminal charges, depending on the severity of the offense. It’s crucial for drivers to prioritize safety and responsibility on the road, refraining from driving if they’ve consumed alcohol and arranging alternative transportation instead.
