What is BAC?
Your blood alcohol concentration, or BAC, is the amount of alcohol in your blood. As an example, if your BAC is .05%, this means you have 50 milligrams of alcohol in 100 millitres of blood. Thus, each drink you have within a certain timeframe increases your BAC.
A number of factors affect how quickly your BAC rises and drops. Body type, weight and food intake at the time of drinking can all impact your BAC. Since women tend to be smaller than men and have more fatty tissue, a woman who drinks as much alcohol as a man usually has a higher BAC.
Legal and Administrative BAC Limits
In Canada, the Criminal Code BAC limit is .08%. This is the level at which Criminal Code impaired driving charges can be laid. It is important to realize, though, that even small amounts of alcohol can impair driving ability.
That is why just about every province and territory in Canada has administrative laws for drivers whose BACs are .05% and over. Drivers at these levels do not face criminal impaired driving charges, but they are subject to licence suspensions ranging from 24 hours to 7 days depending on the province or territory. Provincial administrative licence suspension programs also include escalating suspensions for repeat infractions, vehicle impoundments, education and remedial program requirements and alcohol ignition interlocks.
Young Drivers – No Safe BAC
Young drivers in many provinces and territories have a .00% BAC requirement. They may range for the duration of the graduated licensing program or may extend until they are 21 years of age, depending on the jurisdiction. These special rules for young drivers reflect the very serious increased risks seen when young people mix drinking with driving.
Best Practice – Play it Safe!
The safest way, always, is to separate drinking from driving entirely. If you are going to be drinking don’t risk a licence suspension or worse, a crash — plan alternate transportation home.
