Oakville, Ontario – Mothers Against Drunk Drivers (MADD) Canada has issued a warning to the public not to depend on the reliability of alcohol calculators, used to inform them on how many drinks they can consume before reaching the legal limit of 0.08 per cent blood alcohol concentration (BAC).

“These alcohol calculators are general and not accurate to any person’s specific situation,” said Andrew Murie, MADD Canada CEO. “As rough estimates, the numbers provided by alcohol calculators can’t be considered to be reliable. Anyone drinking and using a calculator to factor how much they can drink and legally drive is just taking an unnecessary risk. Research indicates that impairment of key driving skills begins with the first drink. So the safest way to protect yourself and others is to separate your drinking from your driving. It is best not to drink at all if you intend on driving a vehicle.”

Murie warned that many factors determine a person’s BAC, including weight, gender, alcohol tolerance, how fast the alcohol is being consumed, and whether the person is eating. “There is no calculation table that captures all BAC factors, and to use any such BAC chart or alcohol calculator is just foolhardy,” he said.
