  1. What is the legal BAC limit for driving in Ontario?

    Answer: 0.08%

    The Criminal Code of Canada sets the legal BAC limit at 0.08%. However, Ontario also imposes administrative penalties starting at 0.05% (warn range).

  2. Why doesn't coffee help 'sober up' an intoxicated person?

    Answer: Coffee only makes you a wide-awake drunk — it doesn't reduce BAC or impairment

    Caffeine is a stimulant that may make someone feel more alert, but it has zero effect on blood alcohol level or the liver's rate of alcohol metabolism. The person remains equally impaired.

  3. What happens when someone drinks alcohol on an empty stomach?

    Answer: Alcohol is absorbed much faster, leading to quicker and higher BAC peaks

    Food in the stomach slows alcohol absorption by closing the pyloric valve. On an empty stomach, alcohol passes quickly to the small intestine where it's rapidly absorbed into the bloodstream.

  4. At approximately what BAC level do most people begin to show visible signs of impairment?

    Answer: 0.05%

    Most people show noticeable impairment at around 0.05% BAC: relaxed inhibitions, slight impairment of judgment, and mild coordination issues. Some show signs even earlier.

  5. What is 'tolerance' to alcohol and does it affect BAC?

    Answer: Regular drinkers may show fewer visible signs but BAC and actual impairment remain the same

    Tolerance means a person may not show obvious signs of impairment, but their BAC and actual impairment level are the same. This makes tolerance dangerous — the person appears less drunk than they are.

  6. How does carbonation in drinks (like champagne or mixed drinks with soda) affect alcohol absorption?

    Answer: Carbonation speeds up alcohol absorption

    Carbonation increases the rate of alcohol absorption by irritating the stomach lining and speeding gastric emptying into the small intestine, where most absorption occurs.
