Over 80 Defence
Charged with driving with a blood alcohol concentration at or over the legal limit? An Over 80 charge is technical, science-driven, and defensible.
Overview
Understanding the charge.
In Ontario, it is a criminal offence to operate a motor vehicle with a blood alcohol concentration (BAC) of 80 milligrams of alcohol in 100 millilitres of blood or more, within two hours of driving. This is commonly known as an ‘Over 80’ charge and is prosecuted under section 320.14(1)(b) of the Criminal Code of Canada.
Unlike an impaired driving charge, the Crown does not have to prove that your ability to drive was actually affected. The case turns almost entirely on the breath readings and the procedures the police followed to obtain them — which is exactly where these files are won and lost.
